What is Congestive Heart Failure

Congestive heart failure (CHF), is when the heart is unable to pump sufficiently to maintain blood flow to meet the body’s needs.

Heart failure affects nearly 6 million Americans. Roughly 670,000 people are diagnosed with heart failure each year. It is the leading cause of hospitalization in people older than age 65.

Heart failure does not mean the heart has stopped working. Rather, it means that the heart’s pumping power is weaker than normal. Blood moves through the heart and body at a slower rate, and pressure in the heart increases. As a result, the heart cannot pump enough oxygen and nutrients to meet the body’s needs.

The chambers of the heart may respond by stretching to hold more blood to pump through the body or by becoming stiff and thickened. The heart muscle walls may eventually weaken and become unable to pump as efficiently. As a result, the kidneys may respond by causing the body to retain fluid (water) and salt. If fluid builds up in the arms, legs, ankles, feet, lungs, or other organs, the body becomes congested, and congestive heart failure is the term used to describe the condition.
