Many conditions can lead to heart failure, including the following:
- Coronary Artery Disease: When plaque builds up in the arteries, less blood can reach the heart, causing it to work harder.
- Heart attack: heart attacks can essentially kill parts of the heart muscle which were starved of oxygen, making the heart work more to compensate for the lost muscle.
- Severe lung disease: if the lung??s ability to provide enough oxygen to the body is impaired, the heart has to compensate by pumping more blood.
