Blood pressure is determined by cardiac output and total peripheral resistance. Hypertension is defined as blood pressure higher than 140/90 mmHg. Common drug classes for treating hypertension include diuretics, beta blockers, calcium channel blockers, ACE inhibitors, ARBs, and vasodilators. Diuretics work by inhibiting sodium reabsorption in the kidneys, thereby increasing urine output. Beta blockers reduce blood pressure by blocking the effects of epinephrine to decrease cardiac output and heart rate. Potential side effects of beta blockers include bronchospasm.
Hypertension is also known as high blood pressure. There are mainly two type of blood pressure i.e. systolic and another one is diastolic . The hypertension are categories into two parts that is primary hypertension and secondary hypertension. People are suffering from 3 stage during the condition of hypertension. There are following agents are used to treat hypertension like calcium channel blockers, ACE inhibitors, beta blocker, alpha + beta blockers these are commonly used.
The document discusses medications used to treat cardiac conditions like hypertension, coronary artery disease, and congestive heart failure. It describes several classes of drugs and their effects, such as diuretics which reduce blood volume, ACE inhibitors which lower blood pressure, and beta blockers which decrease heart rate and oxygen demand. The goals of treatment are outlined as reducing risk factors and maintaining normal blood pressure, heart rate, and cholesterol levels. Nursing considerations are also highlighted, like monitoring for side effects and ensuring medication adherence.
The document discusses the regulation of blood pressure and hypertension. It defines normal blood pressure and hypertension. The causes of primary and secondary hypertension are described. The pathophysiology involves the baroreflex and renin-angiotensin-aldosterone system. Treatment includes non-pharmacological methods as well as various classes of antihypertensive drugs such as ACE inhibitors, calcium channel blockers, diuretics, and beta blockers.

Basic understandings in the Heart FailureAryendu kumar
Congestive heart failure occurs when the heart is unable to pump enough blood to meet the body's needs. Common causes include high blood pressure, cardiomyopathy, abnormal heart rhythms, and coronary artery disease. Symptoms include fluid retention leading to peripheral edema and pulmonary edema. Treatment involves reducing preload and afterload on the heart to increase cardiac output and relieve symptoms. Key drug classes used are diuretics, ACE inhibitors, beta blockers, vasodilators, and inotropic drugs. Non-pharmacological treatments include sodium and fluid restriction and exercise. The goal of treatment is management of symptoms and slowing disease progression.
This document provides an overview of heart failure, including its causes, symptoms, and goals of treatment. It discusses the key physiological compensatory mechanisms in heart failure progression, including increased sympathetic nervous system activity, renin-angiotensin-aldosterone system activation, and myocardial hypertrophy. These compensations initially help the failing heart but ultimately lead to further deterioration. The document outlines pharmacologic interventions for heart failure, focusing on inhibitors of the renin-angiotensin-aldosterone system like angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, which reduce workload on the heart and improve outcomes.

Congestive cardiac failure occurs when the heart cannot pump enough blood to meet the body's needs. It results from structural or functional abnormalities of the heart. The key functions of the heart are to supply oxygen and substrates to tissues through adequate blood flow and receive blood returning from tissues. When the heart cannot fulfill these functions due to issues with its structure, filling, contractility, heart rate, or afterload, congestive cardiac failure develops. Common causes include coronary artery disease, hypertension, diabetes, and valvular heart disease. Over time, compensatory mechanisms like increased sympathetic activity and fluid retention can worsen the condition. Treatment involves managing symptoms, improving cardiac function, and preventing further disease progression through medications, diet, exercise,
This document defines hypertension and describes its types, etiology, risk factors, pathophysiology, clinical features, diagnostic evaluations, and management. Hypertension is defined as a systolic blood pressure of 140 mmHg or higher and/or a diastolic blood pressure of 90 mmHg or higher. It is managed primarily through lifestyle modifications like diet and exercise changes as well as pharmacological therapies including diuretics, beta blockers, ACE inhibitors, and calcium channel blockers. Nursing care involves monitoring the patient's condition, educating on lifestyle changes, and ensuring proper treatment adherence.
The document discusses different types of fungal diseases (mycoses). It describes four main groups: 1) superficial mycoses which grow on the skin surface, 2) cutaneous mycoses which grow in superficial skin layers like athlete's foot and ringworm, 3) subcutaneous mycoses which penetrate below the skin, and 4) systemic mycoses which can infect internal organs. Examples of different fungal diseases are provided for each group. Common antifungal drugs and their mechanisms of action and side effects are also summarized.

5. Blood pressure is the force exerted by blood against the
walls blood vessels.
Factors that determine the blood pressure:
1- Cardiac output (CO): Cardiac output is the volume of
blood the heart pumps per minute
2- Total peripheral resistance (PR).
3- Elasticity of the aorta and large arteries.
4- Blood volume and circulatory capacity.
BP = CO X PR
6. What is afterload: Afterload is the
pressure against which the heart
works to eject blood during systole.
What is preload: ??
10. Baroreceptors are pressure sensors. Their function
is to sense pressure changes.
Baroreflex or baroreceptor reflex is a homeostatic
mechanisms that helps to maintain blood pressure at
nearly normal level.

15. Beta-blockers are drugs that bind to beta- receptors.
These drugs block the binding of norepinephrine and
epinephrine to these receptors.
Beta-blockers are sympatholytic drugs.
β1-receptors are located commonly in the heart and
kidneys.
β2- receptors are located mainly in the lungs,
gastrointestinal tract, liver, uterus, vascular smooth
muscle, and skeletal muscle.
β3- adrenergic receptors are located in fat cells.

17. Hypertension is associated with an increase
cardiac output. Beta-blockers decrease blood
pressure by reducing cardiac output.
• Hypertension in some patients is caused by
emotional stress, which causes enhanced
sympathetic activity. Beta-blockers can be very
effective in these patients.

21. Bronchoconstriction can occur when non-selective
beta-blockers are given to asthmatic patients.
Therefore, non-selective beta-blockers are
contraindicated in patients with asthma or chronic
obstructive pulmonary disease.
Bronchoconstriction occurs because sympathetic
nerves innervating the bronchioles normally activate
β2-adrenoceptors that promote bronchodilation.
Beta-blockers can also mask the tachycardia that
serves as a warning sign for insulin-induced
hypoglycemia in diabetic patients; therefore, beta-
blockers should be used cautiously in diabetics.

23. Heart: Blockade of beta1-receptors in the sino-
atrial node reduces heart rate (negative
chronotropic effect) and blockade of beta1-
receptors in the myocardium decrease cardiac
contractility (negative inotropic effect).
26. Kidney: Blockade of beta1-receptors inhibit the release of renin from
juxta-glomerular cells and thereby reduce the activity of the renin-
angiotensin-aldosterone system.
27. Renin is a proteolytic enzyme that is released into
the circulation by the kidneys. Its release is
stimulated by:
sympathetic nerve activation (acting through β1-
adrenoceptors)
renal artery hypotension (caused by systemic
hypotension or renal artery stenosis)
decreased sodium delivery to the distal tubules of
the kidney.
28. The renin-angiotensin-aldosterone system (RAAS)

resistance, which together influence cardiac
output and arterial pressure.
There are three important components to this
system: 1) renin, 2) angiotensin, and 3)
aldosterone. Renin, which is released primarily by
the kidneys, stimulates the formation of
angiotensin in blood and tissues, which in turn
stimulates the release of aldosterone from the
adrenal cortex.
29.
30. Angiotensin2 functions:
Constricts resistance vessels increasing systemic
vascular resistance and arterial pressure
Stimulates reabsorption.
increase the release aldosterone, which in turn acts
on the kidneys to increase sodium and fluid retention
Stimulates the release of vasopressin (antidiuretic
hormone, ADH) from the posterior pituitary, which
increases fluid retention by the kidneys
Stimulates thirst centers within the brain
Enhancing sympathetic adrenergic function
Stimulates cardiac hypertrophy and vascular
hypertrophy.
32. ACE inhibitors have the following actions:
Dilate arteries and veins by blocking angiotensin II
formation
Down regulate sympathetic activity
Promote renal excretion of sodium and water
(natriuretic and diuretic effects) by blocking the
effects of angiotensin II in the kidney and by
blocking angiotensin II stimulation
of aldosterone secretion. This reduces blood
volume, venous pressure and arterial pressure.
Inhibit cardiac remodeling associated with
chronic hypertension, heart failure, and myocardial
infarction.
In cardiology, ventricular remodeling (or cardiac remodeling) refers to
changes in the size, shape, structure, and function of the heart.
35. Dry cough
First-dose hypotension (due to vasodilatation)
Angioedema: it is a serious type of skin reaction
that affects the skin layer and also the tissues
Increased blood-potassium level (hyperkalemia)
36.
37. Patients with bilateral renal artery stenosis may
experience renal failure if ACE inhibitors are
administered. The reason is that the elevated
circulating and intrarenal angiotensin II in this
condition constricts the efferent arteriole more
than the afferent arteriole within the kidney, which
helps to maintain glomerular capillary pressure
and filtration. Removing this constriction by
blocking circulating and intrarenal angiotensin II
formation can cause an abrupt fall in glomerular
filtration rate.
38. Renal artery stenosis is a narrowing
of arteries that carry blood to one or both of the
kidneys.
39. Patients with renal artery stenosis, the kidneys
release large amounts of renin.
High angiotensin II serve to maintain glomerular
filtration by two mechanisms: elevation of blood
pressure and constriction of efferent glomerular
arterioles.
When ACE is inhibited, causing angiotensin II
levels to fall, the mechanisms that had been
supporting glomerular filtration fail, causing urine
production to drop
40. Diuretics. Diuretics may intensify first-dose
hypotension. To prevent this interaction, diuretics
should be withdrawn 1 week prior to initiating ACE
inhibitor treatment
ACE inhibitors increase the risk of hyperkalemia
caused by potassium supplements and
potassium-sparing diuretics
41. Candesartan
Irbesartan
Losartan
Olmesartan
Telmisartan
Valsartan
These drugs have very similar effects
to angiotensin converting enzyme (ACE)
inhibitors and are used for the same indications
(hypertension, heart failure, post- myocardial
infarction).
42. A diuretic is any substance that promotes diuresis
(increased production of urine).
DIURETICS
Diuretics enhance the removal of sodium and water from
body through kidneys.

44. Types of diuretics
Thiazides: Hydrochlorothiazide, Chlorthalidone, indapamide
MOA:
these drugs Inhibit sodium-chloride transporter in the
distal tubule. This transporter normally reabsorbs about
5% of filtered sodium.
Loop diuretics: Furosemide (lasix), Torsemide, Bumetanide
MOA: Loop diuretics inhibit the sodium-potassium-chloride
co-transporter in the thick ascending limb. This transporter
normally reabsorbs about 25% of the sodium load.
Potassium-sparing diuretics: spironolactone and eplerenone.
50. Calcium channel blockers decrease the amount of
calcium entering cardiac and smooth muscle cells
by blocking voltage-gated calcium channels.
This causes blood vessels to relax and widen
(vasodilate), improves oxygen supply to the heart
51. Calcium-channel blockers bind to L-type calcium channels
located on the vascular smooth muscle, cardiac myocytes, and
cardiac nodal tissue (sinoatrial and atrioventricular nodes).
These channels are responsible for regulating the influx of
calcium into muscle cells, which in turn stimulates smooth
muscle contraction and cardiac myocyte contraction.
In cardiac nodal tissue, L-type calcium channels play an
important role in pacemaker currents.
Therefore, by blocking calcium entry into the cell, there is,
vasodilation,
Decreased myocardial force generation (negative inotropy),
decreased heart rate (negative chronotropy),
Decreased conduction velocity within the heart (negative
dromotropy),
