This document provides an overview of congestive heart failure, including: 1. Heart failure results from structural or functional abnormalities that impair the ventricle's ability to pump or fill with blood. 2. A vicious cycle occurs where heart dysfunction causes fluid retention through activation of the renin-angiotensin-aldosterone system. 3. Treatment involves controlling symptoms with diuretics and drugs like ACE inhibitors, beta blockers, and aldosterone antagonists to slow disease progression.
