Common Causes of Heart Failure


Transcript

Any condition or disease that damages your heart’s ability to pump blood can cause heart failure.

For example, the most common cause is coronary artery disease in which blood vessels that supply your heart muscle,

called coronary arteries, become blocked by a fatty substance called plaque.

Other common causes of heart failure include uncontrolled high blood pressure,

and high blood sugar in diabetes.

Less common causes of heart failure include:

diseased, infected, or damaged heart valves, irregular heartbeats called arrhythmias,

heart defects, poisons or substance abuse, lung diseases, and breathing problems during sleep, called sleep apnea.
