Causes of Heart Failure
Heart failure is often a long-term (chronic) condition, but it may come on really fast. As the heart's pumping becomes less effective, blood may back up in other areas of the body. Fluid may build up in the lungs, liver, gastrointestinal tract, and the arms and legs.
The most common causes of heart failure are:
- Coronary artery disease (CAD), a narrowing of the small blood vessels that supply blood and oxygen to the heart. This can weaken the heart muscle over time or suddenly.
- High blood pressure that is not well-controlled, leading to problems with stiffness, or eventually leading to muscle weakening.
