Full Answer
What is the role of beta blockers in heart failure?
The use of beta blockers which may inhibit sympathetic activity, might reduce the risk of disease progression in heart failure, improve symptoms and increase survival.
Are antihypertensive drugs effective for prostatic hypertrophy of the heart?
Background: ABs, found to increase the risk of HF in the ALLHAT (Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack Trial) trial, are commonly used for prostatic hypertrophy, including in those with or at risk for HF.
What is the mechanism of action of beta blockers?
A. Beta-blockers inhibit the release of renin, which in turn prevents the formation of angiotensin II, which causes vasoconstriction. B. Beta-blockers decrease the rate at which the heart beats and reduce the force of the contractions of the heart.
What is the role of metoprolol in the treatment of CHF?
Several large clinical trials with metoprolol, carvedilol and bisoprolol have shown that long term use of these agents can improve left ventricular function and symptoms of CHF, it may also reduce hospital readmission and decrease mortality.
Which beta blocker is best for CHF?
Carvedilol and nebivolol are the third generation beta blockers of choice for heart failure together with the second generation beta blockers bisoprolol and metoprolol succinate.
Can beta blockers be used in CHF?
Current guidelines recommend the use of beta blocker in mild, moderate and severe CHF, in the absence of contraindications or tolerance in combination with ACE inhibitor and diuretics.
Which beta blocker is used in heart failure?
BETA-BLOCKER SELECTION AND DOSAGE Carvedilol is the only agent labeled by the FDA for use in patients with heart failure. It is also the only agent that is available in the appropriate starting dosage (3.125 mg twice daily).
Which drug can be indicated in CHF?
Digoxin has been the traditional first drug of choice for CHF, but with protracted controversy about its efficacy and safety. It is hope that new agents as vesnarione, and ibopamine may improve contractility without having adverse consequences.
What does metoprolol do for CHF?
In addition, metoprolol is used to treat patients with heart failure. This medicine is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure.
Why beta-blockers are contraindicated in CHF?
Beta-blockers were contraindicated in CHF because of their intrinsic negative inotropic activity, but have now been shown to be beneficial, partly due to their ability to enhance sensitivity to sympathetic stimulation.
Which one of the following is an alpha and beta-blocker that can be used to treat hypertension and heart failure?
Labetalol, a compound possessing both alpha- and beta-receptor blocking properties, has been found to be effective both as an oral therapy for chronic hypertension and as an intravenous agent in treating hypertensive crisis.
Why is carvedilol preferred in CHF?
Carvedilol improved left ventricular ejection fraction (LVEF) in patients with chronic heart failure (CHF) in numerous studies. Moreover, significantly greater increases from baseline in LVEF were seen with carvedilol than with metoprolol in a double-blind, randomised study and in a meta-analysis.
What is propranolol used for?
It's used to treat heart problems, help with anxiety and prevent migraines. If you have a heart problem, you can take propranolol to: treat high blood pressure. treat conditions that cause an irregular heartbeat (arrhythmia), like atrial fibrillation.
What is the best medication for CHF?

Is digoxin used for CHF?
Digoxin and HF In CHF, contractility is decreased, which in turn reduces cardiac output. Digoxin is effective in patients with CHF because of its positive inotropic properties. Although studies have shown that digoxin reduces hospitalizations and improves symptoms of HF, it has not been proven to decrease mortality.
What treatments are available for congestive heart failure?
Procedures used include:Coronary artery bypass grafting surgery. The most common surgery for heart failure caused by coronary artery disease is bypass surgery. ... Heart valve surgery. ... Implantable left ventricular assist device (LVAD). ... Heart transplant.
What is the most important mechanism for heart failure?
In heart failure, activation of sympathetic nervous system has been described as one of the most important pathophysiologic abnormalities in patients with congestive heart failure and as one of the most important mechanisms that may be responsible for progression of heart failure. The use of beta blockers which may inhibit sympathetic activity, ...
Can you use beta blocker with ACE inhibitor?
Current guidelines recommend the use of beta blocker in mild, moderate and severe CHF, in the absence of contraindications or tolerance in combination with ACE inhibitor and diuretics. Beta blocker should be initiated in patients after maximal medical therapy with diuretics, ACE inhibitor and digitalis and patients already stabilized ...
Does beta blocker help with heart failure?
The use of beta blockers which may inhibit sympathetic activity, might reduce the risk of disease progression in heart failure, improve symptoms and increase survival. Several large clinical trials with metoprolol, carvedilol and bisoprolol have shown that long term use of these agents can improve left ventricular function and symptoms of CHF, ...
What are beta blockers?
A. Beta-blockers inhibit the release of renin, which in turn prevents the formation of angiotensin II, which causes vasoconstriction. B. Beta-blockers decrease the rate at which the heart beats and reduce the force of the contractions of the heart.
What is the effect of a drop in blood pressure on the release of renin?
A drop in systemic blood pressure or a decrease in renal blood flow stimulates the release of renin from the kidneys. Renin initiates reactions that lead to the formation of angiotensin II. Angiotensin II causes vasodilation and the release of aldosterone (sodium retention) and ADH (water retention). These actions normally function ...
What is the role of renin in blood pressure?
These actions normally function to maintain normal blood pressure and blood volume.
What is the difference between preload and afterload?
A. Preload is the force (force of ventricular contraction) that the heart must generate in order to overcome vascular resistance (open the aortic valve) and eject blood out of the left ventricle. Afterload is the amount of blood returning to the heart (venous return).
Why is digitalization similar to the process of administering a loading dose?
A. Digitalization is similar to the process of administering a loading dose because both rapidly produce a therapeutic blood level of drug. B. After the initial administration of digoxin, subsequent daily maintenance doses are lower and adjusted to maintain a therapeutic level of glycoside in the blood.
Does sodium reduce cardiac output?
A. Restriction of sodium intake during diuretic therapy may decrease the edema and congestion that occur with CHF, but it has no effect on the cardiac output. B. Restriction of sodium intake during diuretic therapy may control the edema, congestion, and reduced cardiac output that occur with CHF.
