Heart Failure

Frequently Asked Questions

1. What is heart failure?

In heart failure, the heart cannot pump enough blood through the body. Heart failure develops over time as the pumping action of the heart gets weaker. Heart failure does not mean that the heart has stopped working or is about to stop working.

When the heart is weakened by heart failure, blood and fluid can back up into the lungs and fluid builds up in the feet, ankles, and legs. People with heart failure often experience tiredness and shortness of breath.
