What is congestive heart failure?

Congestive heart failure (CHF) is characterized by the heart's inability to pump blood effectively, leading to a reduced capacity for the heart to supply sufficient blood to meet the body's needs. This condition may result from various underlying issues, such as coronary artery disease, hypertension, or damage to the heart muscle, which impede the heart's ability to function optimally.

In CHF, the heart's pumping action becomes compromised, leading to a buildup of fluid in the lungs and surrounding tissues. This can cause symptoms like shortness of breath, fatigue, and fluid retention. The focus on the heart's ineffective pumping function distinguishes CHF from conditions like excessive pumping or temporary heart issues, as the root problem lies in inadequate output rather than overexertion or brief episodes of impairment.

Understanding the essence of congestive heart failure is crucial for recognizing its symptoms and potential treatments, as it reflects a chronic and often progressive condition requiring long-term management.
