Heart failure
- Reviewed by Mallika Marshall, MD, Contributing Editor
Heart failure occurs when disease, injury, or years of wear and tear interfere with the heart's ability to pump as effectively and efficiently as it should. When that happens, a cascade of physiological changes is set in motion. The end result is that many body parts don't get the blood flow that they need.
Although the term "heart failure" conjures up the catastrophe of a suddenly lifeless heart, the condition is better described as a gradual decline in the heart's ability to pump.
