This document discusses hypertension, including its definition, classification, causes, types (primary and secondary), diagnosis, management through lifestyle changes and medications, complications, and heart failure. Hypertension is defined as blood pressure over 140/90 mmHg. Its causes include lifestyle factors like stress, diet, obesity, and genetics. Treatment involves lifestyle modifications like diet changes and exercise, as well as medications that lower blood pressure such as diuretics, ACE inhibitors, and calcium channel blockers. Complications of uncontrolled hypertension include heart disease, stroke, kidney disease, and cognitive impairment.
Congestive heart failure (CHF) results from any structural or functional cardiac disorder that impairs the ventricle's ability to fill with or eject blood. It is diagnosed based on history, physical exam, chest x-ray, EKG, and echocardiogram. Treatment focuses on restoring normal cardiopulmonary physiology by using ACE inhibitors, beta-blockers, diuretics, and addressing pulmonary complications. Management involves evaluating the patient's stage of CHF and functional classification to determine appropriate pharmacotherapy and monitoring according to guidelines from the American Heart Association.
Cardiogenic shock is defined as persistent hypotension and hypoperfusion due to cardiac dysfunction with adequate filling pressures. It is commonly caused by left ventricular failure due to an extensive acute myocardial infarction. Signs include low blood pressure, decreased cardiac output, and signs of hypoperfusion. Treatment involves optimizing preload, inotropic support, vasopressor therapy, and mechanical circulatory support such as IABP or VAD if refractory to medical management.
Arrhythmias are abnormalities in heart rate or rhythm that arise from problems with the heart's electrical system. They can be caused by issues with impulse formation or conduction. Arrhythmias are classified as tachyarrhythmias, which involve fast heart rates, or bradyarrhythmias, which involve slow heart rates. Common arrhythmias include atrial fibrillation, atrial flutter, and various types of heart block. Diagnosis involves electrocardiography and other cardiac tests. Treatment may involve medications, cardiac ablation, implanted devices, or surgery depending on the type of arrhythmia.

Congestive heart failure (CHF) is a clinical syndrome where the heart is unable to pump enough blood to meet the body's demands. It is a major public health problem and most common in the elderly. CHF results from conditions that increase the heart's workload like valvular diseases or decrease the heart's ability to contract effectively from issues such as a myocardial infarction. As the heart fails to meet circulatory demands, compensatory mechanisms activate but eventually fail, leading to symptoms of fluid overload and organ congestion. Treatment involves controlling symptoms with medications that lower preload and afterload on the heart like diuretics, ACE inhibitors, and beta blockers as well as addressing any underlying causes of heart muscle dysfunction.
Coronary artery disease is caused by atherosclerosis and is a leading cause of death worldwide. As atherosclerosis progresses, fatty deposits build up in the arteries and restrict blood flow. Over many years, risk factors such as high cholesterol, hypertension, smoking, and obesity can cause plaque to build up and rupture, restricting blood flow. Managing modifiable risk factors through lifestyle changes, medication, and medical treatment can help prevent complications from coronary artery disease.
Myocardial infarction, commonly known as a heart attack, occurs when the coronary arteries become blocked, cutting off the blood supply to parts of the heart muscle. This lack of oxygenated blood causes tissues in the myocardial muscles of the heart to die. A myocardial infarction is also referred to as a heart attack and results from prolonged lack of oxygen to the heart muscle cells.

The document outlines the goals of treatment which are to prevent heart attacks and death while reducing angina symptoms. It then discusses the various pharmacological treatments used including nitrates, beta blockers, calcium channel blockers, antiplatelet agents, ACE inhibitors, and ranolazine. Non-pharmacological options like percutaneous coronary
Atrial fibrillation and atrial flutter are types of arrhythmia where the heart beats irregularly. Atrial fibrillation occurs when rapid, irregular electrical signals cause the heart's upper chambers (atria) to beat very fast and irregularly. Atrial flutter is similar but the heart beats fast in a regular pattern. These conditions are diagnosed through electrocardiograms which detect abnormal heart rhythms. Holter monitors and event recorders can also detect arrhythmias over longer periods of time when symptoms occur. Complications include stroke and heart failure, so treatment focuses on rate or rhythm control and preventing clots.
Unstable angina is a form of ischemic heart disease where a person experiences chest pain or discomfort that occurs at rest or with minimal exertion. It is caused by decreased blood supply to the heart muscle due to partial blockage of the coronary arteries. Diagnosis involves taking a medical history, electrocardiogram, cardiac enzyme tests, and stress testing. Treatment consists of blood thinners, nitroglycerin, blood pressure medications, and cholesterol-lowering drugs medically or early cardiac catheterization and angioplasty or bypass surgery if high risk.
Hypertension, or high blood pressure, is a global health problem that affects nearly 1 billion people worldwide. It is poorly controlled, with less than 25% of cases controlled in developed countries and less than 10% in developing countries. If left untreated, hypertension can lead to heart attacks, heart failure, strokes and kidney disease.
The goals of hypertension treatment are to reduce cardiovascular and renal morbidity and mortality by achieving blood pressure targets.

1) Congestive heart failure results from structural or functional abnormalities that impair the heart's ability to pump or fill with blood adequately.
2) As a result, the heart cannot pump enough blood to meet the body's needs, leading to a buildup of fluid in the lungs or tissues.
3) Treatment focuses on lifestyle modifications, medications such as diuretics, ACE inhibitors, beta blockers, and device-based therapies as needed to manage symptoms and improve outcomes.
Heart failure is a condition where the heart cannot pump enough blood to meet the body's needs. It has many potential causes, but is often due to problems with the heart muscle itself or valves. Treatment focuses on managing symptoms with diuretics, and slowing progression with ACE inhibitors, beta-blockers, and aldosterone antagonists. Other therapies aim to improve heart function or treat underlying causes. Prognosis depends on severity but ranges from 5-50% annual mortality.
Heart failure is a common condition where the heart is unable to pump enough blood to meet the body's needs. It can result from structural or functional disorders of the heart. The document provides details on the definition, causes, risk factors, pathophysiology, symptoms, diagnostic evaluation, classification systems, and treatment of heart failure. It emphasizes the importance of controlling risk factors, using medications such as ACE inhibitors and diuretics to manage symptoms, and making lifestyle changes like following a low-sodium diet and exercising regularly.
Pathophysiology of congestive heart failurethunderrajesh
This document provides an overview of congestive heart failure, including its definition, types, causes, symptoms, complications, diagnosis, and treatment. Congestive heart failure occurs when the heart muscle is weakened and cannot pump blood effectively, leading to fluid buildup in tissues and organs. The main types are systolic and diastolic dysfunction. Common causes include hypertension, coronary artery disease, and valvular issues. Symptoms involve fatigue, shortness of breath, and swelling. Treatment focuses on medications like ACE inhibitors, diuretics, beta blockers, and lifestyle changes such as diet, exercise, and stress reduction.
Heart failure results from left ventricular dysfunction and is a common outcome of many cardiovascular diseases. It is characterized by symptoms like dyspnea and fatigue. The main causes are coronary artery disease, hypertension, valvular heart disease and cardiomyopathy. Treatment involves drugs like ACE inhibitors, beta-blockers, diuretics and digoxin to improve symptoms, reduce disease progression and mortality risk. These drugs act via different mechanisms such as neurohormonal inhibition and reducing preload and afterload.
The document discusses cardiac pacemakers. Cardiac pacemakers are electronic devices that use electrical pulses to regulate an abnormal heart rhythm. They consist of two main parts: a pulse generator that creates stimulating impulses, and leads that carry the pulses from the generator to the heart. There are different types of pacemakers including external pacemakers used temporarily and implantable pacemakers that are surgically placed under the skin and directly connected to the heart muscle. Implantable pacemakers can have various features to control heart rate and are powered by batteries that must provide energy for long periods of time.

Jr approach to the patient with varicose veins april 2010John Rowen
Varicose veins affect about 50% of people by age 50, with heredity playing a large role. There are two vein systems - the deep system which circulates most blood and is surrounded by muscle, and the superficial system where varicose veins typically form in the loose subcutaneous tissue. Varicose veins result from primary issues with vein wall integrity as well as secondary causes like deep vein thrombosis obstructing blood flow. Symptoms range from heaviness and aching to night cramps and swelling. Treatment options include sclerotherapy, laser ablation, compression devices, and surgery.
Advanced stage heart failure can result from any structural or functional issues that reduce the heart's ability to pump blood effectively. Common causes include coronary artery disease, heart attacks, and uncontrolled hypertension. Symptoms vary by individual but can include shortness of breath, fatigue, swelling, and confusion. Diagnosis involves tests like echocardiograms to check the ejection fraction of the left ventricle and blood tests to examine biomarkers like BNP and CRP levels. Treatment is multifaceted, focusing on lifestyle changes, medications, and possibly surgery, with the goals of managing symptoms and improving quality of life.

Hypertension, or high blood pressure, is caused by increased cardiac output and peripheral vascular resistance. It is classified as essential (primary) hypertension which is idiopathic or secondary which has an identifiable cause. Risk factors include family history, race, stress, obesity, sodium intake, alcohol, and tobacco use. Complications affect the heart, brain, kidneys and eyes. Diagnosis involves medical history, physical exam, and tests like ECG and bloodwork. Treatment focuses on lifestyle modifications and may include diuretics, beta blockers, ACE inhibitors, and other medications. Nursing care educates on compliance, diet, exercise and monitoring.
Hypertension, or high blood pressure, affects nearly 1 billion people worldwide. It is a leading cause of death and is poorly controlled in many countries. May 14th is recognized as World Hypertension Day to increase awareness. Hypertension is defined as a systolic blood pressure over 140 mmHg or a diastolic over 90 mmHg. Lifestyle modifications like weight loss, dietary changes, and increased physical activity can help control blood pressure but medication is often required. Treatment goals are to reduce blood pressure below 140/90 mmHg or 130/80 for those with diabetes or kidney disease to lower the risks of complications.
Hypertension, also known as high blood pressure, is a medical condition defined as blood pressure above 140/90 mmHg. It is often asymptomatic but can lead to serious health issues like heart disease or stroke if left untreated. Treatment involves lifestyle modifications like reducing salt intake, exercise, and weight loss. Medications may also be prescribed depending on severity, such as ACE inhibitors, calcium channel blockers, beta blockers, or diuretics. For hypertensive emergencies with very high blood pressure, intravenous drugs are used to rapidly lower the pressure.
The document discusses the role of clinical pharmacists in treating hypertension. It begins with definitions of hypertension and discusses diagnosing and assessing hypertension through medical history, lab tests, and monitoring blood pressure levels. It then covers lifestyle changes, medications, and the roles of clinical pharmacists in managing drug therapy, counseling patients, and working with physicians and nurses to optimize treatment of hypertension. The clinical pharmacist aims to prevent medication-related problems and optimize patient outcomes through their expertise in pharmacotherapy.

Heart disease low blood pressure: Just like any other medical
condition, heart disease has very real consequences. However, in
some cases of the illness, its severity can be reduced when patients
are able to control their blood pressure. Find out how low-pressure
therapy might help you by reading this article!

Blood Pressure: Heart disease low blood
pressure
Blood pressure is a measure of the force of blood pushing against
the walls of the arteries. It can be affected by a number of factors,
including age, sex, obesity, and genetics. There are two types of blood
pressure: systolic and diastolic. Systolic pressure is the maximum
pressure your heart can push against while it’s pumping blood, and
diastolic pressure is the minimum pressure your heart can push
against while it’s pumping blood.
Low blood pressure is a common condition that affects about 50% of
adults over age 50. It can be caused by many things, including obesity,
high blood cholesterol, lack of exercise, and chronic stress. Blood
Pressure Symptoms can include heart disease, stroke, and other
serious health problems.
There are dozens of ways to lower your blood pressure. Some people
need medication to lower their blood pressure, but there are many
effective lifestyle changes you can make to help too. If you have very
low blood pressure, it’s important to talk with your doctor about
what’s best for you.

You might feel like you have high blood pressure when your blood
pressure readings are above 140/90. But you might also have low
blood pressure if your reading is below 120/80.nnBoth high and low
blood pressure can be dangerous, and both can lead to heart
problems, strokes, and even death. If you’re concerned about your
blood pressure, talk to your doctor. But don’t wait to get checked out –
a high or low blood pressure can be the first sign of a serious health
problem. Here are some tips to help keep your blood pressure in
check:
-If you have high blood pressure, follow a healthy diet and exercise
regimen. Eating well-balanced foods and getting regular exercise can
help lower your blood pressure naturally.
-If you have low blood pressure, make sure to get enough fluids and
salt in your diet. This will help keep your blood vessels open and
prevent damage from occurring.

Blood pressure test and Hypotension
Hypotension is a condition in which the body doesn’t have enough
blood pressure. This can be caused by a number of things, including
low blood flow to the brain or heart, excessive fluid retention, and high
blood pressure. The most common way to test for hypotension is with
a blood pressure test. The person t
1) Blood pressure is determined by cardiac output and peripheral vascular resistance. It represents the force exerted by blood on blood vessel walls.
2) Blood pressure is measured by systolic pressure when the heart contracts and diastolic pressure when the heart is at rest between beats.
3) High blood pressure, or hypertension, is classified according to levels of systolic and diastolic pressure. The majority of high blood pressure cases are primary (essential) hypertension which develops gradually over many years without an identifiable cause. Secondary hypertension can be caused by underlying conditions.
Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. Blood pressure is expressed using two measurements - systolic and diastolic pressures. For most adults, normal blood pressure is within the range of 100-130 mmHg systolic and 60-80 mmHg diastolic. High blood pressure is present if the resting blood pressure is persistently at or above 130/80 or 140/90 mmHg. Treatment involves lifestyle modifications and medications such as diuretics, ACE inhibitors, ARBs, calcium channel blockers, and beta blockers. Uncontrolled high blood pressure can lead to damage of vital organs and increase risk of
This document summarizes a seminar presentation on hypertension given by two nursing students. It began with an outline and objectives.

This document defines hypertension and describes its causes, types, symptoms, diagnosis, treatment, and management. Hypertension, also called high blood pressure, is defined as a systolic pressure over 140 mm Hg or diastolic over 90 mm Hg. It has two main types: primary (essential) hypertension which has no identifiable cause, and secondary hypertension which is caused by an underlying condition like kidney disease. Treatment involves lifestyle changes and may include diuretics, beta blockers, ACE inhibitors, or calcium channel blockers to lower blood pressure. Regular monitoring of blood pressure and medication adherence are important for managing the condition and preventing complications like heart attack, stroke, or kidney failure.
Essential hypertension management and treatmentFabio Grubba
This document discusses hypertension (high blood pressure), including its classification, causes, symptoms, diagnosis, and treatment. It defines the different stages of hypertension according to blood pressure readings. Lifestyle modifications are recommended initially, including diet changes and exercise. If lifestyle changes do not control blood pressure, medications such as diuretics, beta-blockers, calcium channel blockers, ACE inhibitors, and other drug classes may be used. The goal of treatment is to prevent complications in target organs like the heart, brain, and kidneys by maintaining a blood pressure below 140/90 mmHg.
Secondary hypertension is high blood pressure caused by an underlying medical condition that affects the kidneys, heart, blood vessels or endocrine system. It differs from primary hypertension which has no clear cause. Proper treatment of the underlying condition can control both secondary hypertension and reduce risks of complications like heart disease, kidney failure and stroke. Some common causes of secondary hypertension include kidney disease, Cushing's syndrome, pheochromocytoma, thyroid problems and obstructive sleep apnea.

Breast cancer :Receptor (ER/PR/HER2 NEU) Discordance.pptxDr. Sumit KUMAR
Receptor Discordance in Breast Carcinoma During the Course of Life
Definition:
Receptor discordance refers to changes in the status of hormone receptors (estrogen receptor ERα, progesterone receptor PgR, and HER2) in breast cancer tumors over time or between primary and metastatic sites.
Causes:
Tumor Evolution:
Genetic and epigenetic changes during tumor progression can lead to alterations in receptor status.
Treatment Effects:
Therapies, especially endocrine and targeted therapies, can selectively pressure tumor cells, causing shifts in receptor expression.
Heterogeneity:
Inherent heterogeneity within the tumor can result in subpopulations of cells with different receptor statuses.
Impact on Treatment:
Therapeutic Resistance:
Loss of ERα or PgR can lead to resistance to endocrine therapies.
HER2 discordance affects the efficacy of HER2-targeted treatments.
Treatment Adjustment:
Regular reassessment of receptor status may be necessary to adjust treatment strategies appropriately.
Clinical Implications:
Prognosis:
Receptor discordance is often associated with a poorer prognosis.
Biopsies:
Obtaining biopsies from metastatic sites is crucial for accurate receptor status assessment and effective treatment planning.
Monitoring:
Continuous monitoring of receptor status throughout the disease course can guide personalized therapy adjustments.
Understanding and managing receptor discordance is essential for optimizing treatment outcomes and improving the prognosis for breast cancer patients.

In general the major causes of hypertension
are the following:
Hectic and stress filled life style
Unhealthy food habits
Obesity
Excessive consumption of liquors
Smoking
Over consumption of tea/coffee
Insufficient rest and sleep
Metabolic disorders
5. Contd……
Hardening of the arteries
Excessive use of pain killers and other strong
medicines
Genetic disorders
Over consumption of oily food and fast food
High salt intake
Emotional and Physical stress
Family history of hypertension
6. Secondary causes
Sleep apnoea
Drug-induced or drug-related
Chronic kidney disease
Primary aldosteronism
Renovascular disease
Chronic steroid therapy and Cushing syndrome
Phaeochromocytoma
Acromegaly
Thyroid or parathyroid disease
Coarctation of the aorta
Takayasu Arteritis
7. Primary hypertension
Primary (essential) hypertension is the most
common form of hypertension, accounting for
90–95% of all cases of hypertension. Numerous
common genetic variants with small effects on
blood pressure have been identified as well as
several environmental factors influence blood
pressure. Insulin resistance, which is common in
obesity and is a component of syndrome X (or
the metabolic syndrome), is also thought to
contribute to hypertension
8. Secondary hypertension
Secondary hypertension results from an
identifiable cause. Renal disease is the most
common secondary cause of hypertension.
Hypertension can also be caused by
endocrine conditions, such as Cushing's
syndrome, hyperthyroidism, hypothyroidism,
acromegaly, Conn's syndrome or
hyperaldosteronism, hyperparathyroidism
and pheochromocytoma.
9. Resistant hypertension
Resistant hypertension is defined as
hypertension that remains above goal blood
pressure in spite of concurrent use of three
antihypertensive agents belonging to
different antihypertensive drug classes
10. Hypertensive crisis
Severely elevated blood pressure (equal to or
greater than a systolic 180 or diastolic of 110 —
sometime termed malignant or accelerated
hypertension) is referred to as a "hypertensive
crisis.People with blood pressures in this range
may have no symptoms, but are more likely to
report headaches (22% of cases) and dizziness
than the general population.Other symptoms
accompanying a hypertensive crisis may include
visual deterioration or breathlessness due to
heart failure or a general feeling of malaise due
to renal failure.
11. Malignant hypertension
A "hypertensive emergency", previously
"malignant hypertension", is diagnosed when
there is evidence of direct damage to one or
more organs as a result of the severely elevated
blood pressure. This may include hypertensive
encephalopathy, caused by brain swelling and
dysfunction, and characterized by headaches
and an altered level of consciousness (confusion
or drowsiness). Retinal papilloedema and/or
fundal hemorrhages and exudates are another
sign of target organ damage. Chest pain may
indicate heart muscle damage
13. Signs and symptoms.
Headaches - Headaches may be experienced due to elevation in blood
pressure. Sometimes morning headaches can also be due to
hypertension.
Dizziness - Dizziness is often experience by people with high blood
pressure. However dizziness cannot always be treated as a symptom of
hypertension. If dizziness is experienced it is always wise to consult a
medical practitioner.
Heart pain
Palpitations
Nosebleeds - Nosebleeds without particular reason might be a symptom
of high blood pressure. It is better to check the blood pressure in such
cases.
Difficulty in breathing
Tinnitus (ringing or buzzing in the ears)
Blurred Vision
Frequent urination

minutes per day, most days of the week
21. Different programs aimed to reduce
psychological stress such a biofeedback,
relaxation or meditation are advertised to
reduce hypertension
22. Medications
Several classes of medications, collectively
referred to as antihypertensive drugs, are
currently available for treating hypertension..
.One or more of these blood pressure medicines
are often used to treat high blood pressure:
Diuretics are also called water pills. They help
your kidneys remove some salt (sodium) from
your body. As a result, your blood vessels don't
have to hold as much fluid and your blood
pressure goes down.
23. Beta-blockers make the heart beat at a slower rate
and with less force.
Angiotensin-converting enzyme inhibitors (also
called ACE inhibitors) relax your blood vessels,
which lowers your blood pressure.
. Angiotensin II receptor blockers (also called
ARBs) work in about the same way as
angiotensin-converting enzyme inhibitors
24. .
Calcium channel blockers relax blood vessels by
stopping calcium from entering cells.
Blood pressure medicines that are not used as
often include:
Alpha-blockers help relax your blood vessels,
which lowers your blood pressure.
Centrally acting drugs signal your brain and
nervous system to relax your blood vessels.
Vasodilators signal the muscles in the walls of
blood vessels to relax.
25. Renin inhibitors, a newer type of medicine for
treating high blood pressure, act by relaxing your
blood vessels
Renin inhibitors work, as the name would suggest,
by inhibiting the activity of renin, the enzyme largely
responsible for angiotensin II levels. In clinical trials,
renin inhibitors have proven effective in not only
lowering blood pressure, but also keeping blood
pressure levels steadier throughout the day.One
renin inhibitor, aliskiren (Tekturna), was approved by
the FDA in 2007. Other drugs in this class are in
development
26. Complications of
hypertension
Hypertension is the most important
preventable risk factor for premature death.
Ischemic heart disease
Strokes
Peripheral vascular disease,
Other cardiovascular diseases
, Including heart failure, aortic aneurysms,
diffuse atherosclerosis, and
pulmonaryembolism
27. Hypertension is also a risk factor for cognitive
impairment and dementia, and chronic
kidney disease. Other complications include
hypertensive retinopathy and hypertensive
nephropathy.
Bleeding from the aorta
28. Researches
Sesame and rice bran oil can treat high blood
pressure and cholesterol, study showSignificant

Yoga benefits high blood pressure through
promoting relaxation of the mind and body.
Practicing yoga helps decrease the negative
impacts of stress, including tension, shallow
breathing and elevated heart rate. It also
improves physical strength and flexibility, plus
may assist with weight loss
29. Heart failure
Heart failure is an illness in which the
pumping action of the heart becomes less
and less powerful. When this happens, blood
does not move efficiently through the
circulatory system and starts to back up,
increasing the pressure in the blood vessels
and forcing fluid from the blood vessels into
body tissues
30. Incidence
Heart failure affects 2% of the adult
population. In the United States, nearly four
million people have heart failure. Each year
about 550,000 new cases are diagnosed. The
condition is more common among African
Americans than Caucasians.
Heart failure affects 1% of people age 50
years or older, about 5% of those age 75 years
or older, and 25% of those age 85 years or
older.
31. Left-sided failure
When the left side of the heart (left ventricle)
starts to fail, fluid collects in the lungs
(pulmonary edema). This extra fluid in the
lungs (pulmonary congestion) makes it more
difficult for the airways to expand as a person
inhales. Breathing becomes more difficult
and the person may feel short of breath,
particularly with activity or when lying down
32. Right-sided failure
When the right side of the heart (right
ventricle) starts to fail, fluid begins to collect
in the feet and lower legs. Puffy leg swelling
(edema) is a sign of right heart failure,
especially if the edema is pitting edema.
33. Biventricular failure
Dullness of the lung fields to finger
percussion and reduced breath sounds at the
bases of the lung may suggest the
development of a pleural effusion .Though it
can occur in isolated left- or right-sided heart
failure, it is more common in biventricular
failure because pleural veins drain both into
the systemic and pulmonary venous system.
When unilateral, effusions are often right
sided.
34. Systolic heart failure
This condition occurs when the pumping
action of the heart is reduced or weakened. A
common clinical measurement is ejection
fraction (EF).. Systolic heart failure is
diagnosed when the ejection fraction has
significantly decreased below the threshold
of 55%.
35. Diastolic heart failure
This condition occurs when the heart can
contract normally but is stiff, or less compliant,
when it is relaxing and filling with blood. The
heart is unable to fill with blood properly, which
produces backup into the lungs and heart failure
symptoms. Diastolic heart failure is more
common in patients older than 75 years of age,
especially in patients with high blood pressure,
and it is also more common in women. In
diastolic heart failure, the ejection fraction is
normal or increased.
36. Causes
Congestive heart failure (CHF) is a syndrome
that can be brought about by several
causes,or a combination of several problems,
including the following:
Weakened heart muscle (cardiomyopathy)
Damaged heart valves
Blocked blood vessels supplying the heart
muscle which may lead to a heart attack (This
is known as ischemic cardiomyopathy.
37. Contd………..
Toxic exposures, such as alcohol or cocaine
Infections, commonly viruses, which for
unknown reasons affect the heart in only
certain individuals
High blood pressure that results in thickening
of the heart muscle (left ventricular
hypertrophy)

48. Symptoms and Signs
Left sided heart failure
Common respiratory signs are tachypnea
and increased work of breathing (non-specific
signs of respiratory distress).
Backward failure of the left ventricle causes
congestion of the pulmonary vasculature,
dyspnea (shortness of breath) on exertion and in
severe cases, dyspnea at rest. orthopnea, occurs.
It is often measured in the number of pillows
required to lie comfortably.
49. "Cardiac asthma" or wheezing
paroxysmal nocturnal dyspnea
Rales or crackles suggestive of pulmonary edema
Cyanosis which suggests severe hypoxemia, is a
late sign of extremely severe pulmonary edema
50. gallop rhythm may be heard as a marker of
increased blood flow, or increased intra-cardiac
pressure
Heart murmurs
Due to reduced systemic circulation,
dizziness, confusion and cool extremities at
rest can occur.
51. Right heart failure
Physical examination may reveal pitting
peripheral edema, ascites,
and hepatomegaly
Increased jugular venous pressure
If the right ventricular pressure is increased,
aparasternal heave may be present,
signifying the compensatory increase in
contraction strength.
52. Backward failure of the right ventricle leads
to congestion of systemic capillaries
peripheral edema or anasarca
Sacral edema in lying patients
Nocturia
Hepatomegaly
Significant liver congestion may result in
impaired liver function, and jaundice and
even coagulopathy
53. What is present in this extremity, common to right sided HF?
56. Diagnostic measures
Imaging
Echocardiography is commonly used to support a
clinical diagnosis of heart failure. This modality
uses ultrasound to determine the stroke volume ,
the end-diastolic volume , and the SV in
proportion to the EDV, a value known as
the ejection fraction (EF Normally, the EF should
be between 50% and 70%; in systolic heart failure,
it drops below 40%. Echocardiography can also
identify valvular heart disease and assess the state
of the pericardium.
59. Chest X-rays are frequently used to aid in the
diagnosis of CHF. In the compensated patient,
this may show cardiomegaly ), quantified as
the cardiothoracic ratio (proportion of the heart
size to the chest). In left ventricular failure, there
may be evidence of vascular redistribution
("upper lobe blood diversion" or
"cephalization"), Kerley lines, cuffing of the areas
around thebronchi, and interstitial edema.
62. Electrophysiology
An electrocardiogram (ECG/EKG) may be
used to identify arrhythmias, ischemic heart
disease, right and left ventricular
hypertrophy, and presence of conduction
delay or abnormalities (e.g. left bundle
branch block). Although these findings are
not specific to the diagnosis of heart failure a
normal ECG virtually excludes left ventricular
systolic dysfunction
64. Others
comparing BNP and N-terminal pro-BNP (NTproBNP) in the
diagnosis of heart failure, BNP is a better indicator for heart
failure and left ventricular systolic dysfunction.
Angiography
Heart failure may be the result of coronary artery
disease, and its prognosis depends in part on the
ability of the coronary arteries to supply blood to
the myocardium.As a result, coronary
catheterization may be used to identify possibilities
for revascularisation through percutaneous coronary
intervention or bypass surgery
65. Classification
There are many different ways to categorize
heart failure, including the side of the heart
involved (left heart failure versus right heart
failure).
whether the abnormality is due to
insufficient contraction (systolic dysfunction),
or due to insufficient relaxation of the heart
(diastolic dysfunction), or to both.
66. NYHA –functional
classification
Functional classification generally relies on the New York
Heart Association functional classification. The classes (I-IV)
are:
Class I: no limitation is experienced in any activities; there
are no symptoms from ordinary activities.
Class II: slight, mild limitation of activity; the patient is
comfortable at rest or with mild exertion.
Class III: marked limitation of any activity; the patient is
comfortable only at rest.
Class IV: any physical activity brings on discomfort and
symptoms occur at rest.
This score documents severity of symptoms, and can be
used to assess response to treatmen
67. ACC- stages of heart faiure
American College of Cardiology/American Heart
Association working group introduced four stages of heart
failure:
Stage A: Patients at high risk for developing HF in the future but
no functional or structural heart disorder.
Stage B: a structural heart disorder but no symptoms at any
stage.
Stage C: previous or current symptoms of heart failure in the
context of an underlying structural heart problem, but managed
with medical treatment.
Stage D: advanced disease requiring hospital-based support, a
heart transplant or palliative care.
The ACC staging system is useful in that Stage A encompasses
"pre-heart failure" — a stage where intervention with treatment
can presumably prevent progression to overt symptoms.
68.
69. Algorithm
There are various algorithms for the diagnosis of
heart failure. For example, the algorithm used by
the Framingham Heart Study adds together
criteria mainly from physical examination.
Framingham criteria
By the Framingham criteria, diagnosis of
congestive heart failure requires the
simultaneous presence of at least 2 of the
following major criteria or 1 major criterion in
conjunction with 2 of the following minor criteria
70. Framingham criteria
Major criteria:
Cardiomegaly on chest radiography
S3 gallop (a third heart sound)
Acute pulmonary edema
Paroxysmal nocturnal dyspnea
Crackles on lung auscultation
Central venous pressure of more than 16 cm H2O at the
right atrium
Jugular vein distension
Positive abdominojugular test
Weight loss of more than 4.5 kg in 5 days in response to
treatment
71. Minorcriteria
Tachycardia of more than 120 beats per minute
Nocturnal cough
Dyspnea on ordinary exertion
Pleural effusion
Decrease in vital capacity by one third from maximum recorded
Hepatomegaly
Bilateral ankle edema
Minor criteria are acceptable only if they can not be attributed to
another medical condition such as pulmonary hypertension,
chronic lung disease, cirrhosis, ascites, or the nephrotic
syndrome. The Framingham Heart Study criteria are 100%
sensitive and 78% specific for identifying persons with definite
congestive heart failure.
72. Congestive Heart Failure
Treatment
Lifestyle modifications
Elevate the feet and legs if they are swollen.
Eat a reduced-salt diet.
Weigh in every morning before breakfast and
record it in a diary that can be shown to a health
care provider.
Avoid the following:
Not taking prescribed medications
Smoking
Alcohol (up to one drink per day is usually fine)
73. Excessive emotional stress and/or depression (seek
professional help)
avoid high altitude :breathing is more difficult
because of the lower level of oxygen in the
atmosphere; pressurized cabin air travel is usually
fine
Stay active
Exercise; consult your doctor to determine a safe
workout routine.
If you are overweight, lose weight.
Reduce cholesterol
Get enough sleep
74. Supplemental oxygen
Oxygen therapy may become necessary as
heart failure progresses. The need is based on
the degree of pulmonary congestion and
resulting hypoxia. Some patients require
supplemental oxygen only during activity
75. Medications
Diuretics (water pills):
Diuretics cause the kidneys to remove excess
salt and accompanying water from the
bloodstream, thereby reducing the amount
of blood volume in circulation.
Diuretics commonly used in heart failure
include furosemide (Lasix), bumetanide
(Bumex), hydrochlorothiazide (
spironolactone (Aldactone), eplerenone ,
triamterene, torsemide, or metolazone
76. Digoxin (Lanoxin): Digoxin is a mild inotrope
and, in some cases, is beneficial as an add-on
therapy to ACE inhibitors and beta-blockers.
It is the most common form of digitalis.
Digoxin can reduce heart failure symptoms
and hospitalizations, but it does not prolong
life.
Digoxin is mainly used as an antiarrhythmic
to control the rate of the heart in atrial
fibrillation and flutter
77. Vasodilators: These medications enlarge the
small arteries or arterioles, which relieve the
systolic workload of the left ventricle.
ACE inhibitors are the most widely used
vasodilators for congestive heart failure. They
block the production of angiotensin II, which is
abnormally high in congestive heart failure. Some
common examples of ACE inhibitors are captopril,
enalapril. Lisino pril
78. Angiotensin II receptor blockers (ARBs) work by
preventing the effect of angiotensin II at the tissue level.
Examples of ARB medications include olmesartan ,
losartan (Cozaar),
Nitrates are venous vasodilators that include isosorbide
mononitrate (Imdur) and isosorbide dinitrate (Isordil).
They are commonly used in combination with an arterial
vasodilator, such as hydralazine
Nitroglycerin is a nitrate preparation that is administered
to treat acute chest pain, or angina.
Hydralazine (Apresoline) is a smooth muscle arterial
vasodilator that may be used for congestive heart failure.
79. Beta-blockers: These drugs slow down the
heart rate, lower blood pressure, and have a
direct effect on the heart muscle to lessen the
workload of the heart. Specific beta-blockers,
such as carvedilol and long-acting
metoprolol , have been shown to decrease
symptoms, hospitalization due to congestive
heart failure, and deaths.
80. Inotropes: IV inotropes are stimulants, such
as dobutamine and milrinone which increase
the pumping ability of the heart. These are
used as a temporary support of a very weak
left ventricle that is not responding to
standard congestive heart failure therapy.
Commonly used inotropes are dobutamine
(Dobutex) and milrinone (Primacor).
Phenylephrine may be used when a patient is
suffering with severe low blood pressure.
81. Congestive Heart Failure
Interventions
Angioplasty: This is an alternative to coronary
bypass surgery for some people whose heart
failure is caused by coronary artery disease and
may be compounded by heart damage or a
previous heart attack
Pacemaker: This device controls the rate of the
heartbeat. A pacemaker may keep the heart
from going too slow, increasing heart rate when
the heart is not increasing enough with activity.
It also helps sustain regular rates when the heart
is not beating in a coordinated way
82. Implantable Cardioverter Defibrillator
(ICD): This device returns the heart to a
normal rhythm by pacing or delivering an
electrical shock, with a life-threatening
arrhythmia.
ICDs are indicated for ischemic or
nonischemic cardiomyopathy patients with
slight or marked physical limitations and low
left ventricular ejection fractions (<30% to
35%),
83. CRT-Cardiac
Resynchronization Therapy
HOW IT WORKS:
Standard implanted pacemakers -
equipped with two wires (or "leads")
conduct pacing signals to specific regions
of heart (usually at positions A and C).
Biventricular pacing devices have added a
third lead (to position B) that is designed
to conduct signals directly into the left
ventricle. Combination of all three lead >
synchronized pumping of ventricles, inc.
efficiency of each beat and pumping more
blood on the whole.
84. Temporary Cardiac Support: An intra-aortic
balloon pump is used as a temporary
support of left ventricle function, such as
in a large heart attack, waiting for the
heart to recover
85. Surgical management
Left ventricle assist device (LVAD): This
device is surgically implanted to mechanically
bypass the left ventricle. It can be used as a
“bridge to transplant” until a heart transplant
is available.
Alternatively, LVADs are also being used as
“destination therapy” in patients who are not
eligible for a transplant, but only at approved
specialized medical centers.
87. Total artificial heart (TAH): For patients with
severe, end-stage heart failure.
These devices are most commonly used as a
temporary bridge to heart transplantation, but
can be used as destination therapy in patients
who are not eligible for a transplant and have a
high chance of mortality within 30 days.
This technique is constantly improving, but is still
limited to specialized centers and is considered
experimental at this time.

89. complications
Pleural effusion
Atrial fibrillation (most common
dysrhythmia)
Loss of atrial contraction (kick) -reduce CO by
10% to 20%
Promotes thrombus/embolus formation inc. risk
for stroke
Treatment may include cardioversion,
antidysrhythmics, and/or anticoagulants
90. Complications
High risk of fatal dysrhythmias (e.g., sudden
cardiac death, ventricular tachycardia) with HF
and an EF <35%
HF lead to severe hepatomegaly, especially with
RV failure
Fibrosis and cirrhosis - develop over time
Renal insufficiency or failure
91. Prognosis
Prognosis in heart failure can be assessed in
multiple ways including clinical prediction rules
and cardiopulmonary exercise testing. Clinical
prediction rules use a composite of clinical
factors such as lab tests and blood pressure to
estimate prognosis
ADHERE Tree rule indicates that patients
with blood urea nitrogen < 43 mg/dl and systolic
blood pressure at least 115 mm Hg have less than
10% chance of inpatient death or complications
92. Contd………..
cardiopulmonary exercise testing (CPX
testing). CPX testing is usually required prior to
heart transplantation as an indicator of
prognosis. Cardiopulmonary exercise testing
involves measurement of exhaled oxygen and
carbon dioxide during exercise. The peak oxygen
consumption (VO2 max) is used as an indicator
of prognosis. As a general rule, a VO2 max less
than 12–14 cc/kg/min indicates a poor survival
and suggests that the patient may be a
candidate for a heart transplant. Patients with a
VO2 max<10 cc/kg/min have clearly poorer
prognosis

Editor's Notes
BNP belongs to a family of protein hormones called natriuretic peptides, which includes ANP, BNP, CNP, and DNP. Natriuretic peptides are part of the body’s natural defense mechanisms designed to protect the heart from stress and play an important role in regulating circulation. They promote urine excretion, relax blood vessels, lower blood pressure, and reduce the heart’s workload. Most scientific study has focused on ANP and BNP.
Measurement of BNP helps doctors diagnose and treat congestive heart failure. In this condition, the heart is unable to pump blood efficiently, and the heart chambers swell with blood. As the heart cells stretch, they produce extra BNP, which pours into the bloodstream. By measuring blood levels of BNP, doctors can spot signs of congestive heart failure in its early stages, when it may be hard to distinguish from other disorders. A normal BNP level is about 98% accurate in ruling out heart failure. And, in general, the higher the level, the worse the heart failure. Falling BNP levels indicate that treatment is working.
