Name two strategies for the treatment of chronic heart failure.

<p>Increase cardiac contractility and reduce preload and/or afterload in order to decrease cardiac work demand.</p> Signup and view all the answers

What is the mechanism of action of beta blockers in heart failure?

<p>The paradoxical use of beta blockers is beneficial in heart failure as they reduce heart rate and improve myocardial function.</p> Signup and view all the answers

What is the mechanism of action of drugs that inhibit the renin-angiotensin-aldosterone system?

<p>Drugs that inhibit the renin-angiotensin-aldosterone system block the production or action of angiotensin II, a potent vasoconstrictor, and aldosterone, which promotes sodium and water retention.</p> Signup and view all the answers

What is the mechanism of action of digoxin and how does it increase myocardial contractility?

<p>Digoxin increases myocardial contractility by inhibiting the sodium-potassium ATPase pump, leading to increased intracellular calcium concentration and enhanced contractility.</p> Signup and view all the answers

What are the main benefits of using renin-angiotensin system inhibitors in heart failure?

<p>Reduce salt and water retention, reduce vasoconstriction, reduce vascular resistance, reduce afterload, improve tissue perfusion, reduce ventricular remodeling and hypertrophy</p> Signup and view all the answers

Why are beta-blockers used in heart failure?

<p>They allow the ventricle to fill more completely during diastole, reduce renin release by the kidney, and can increase renal perfusion at low doses</p> Signup and view all the answers
