Heart failure is a condition in which the heart is unable to pump blood effectively enough to meet the body's needs. This can occur when the heart becomes too weak or too stiff to function properly.
There are different causes for heart failure, including:
- Coronary artery disease (CAD): Narrowed arteries reduce blood flow to the heart muscle.
- High blood pressure (hypertension): Over time, it can make the heart work harder and lead to heart failure.
- Heart valve disease: Narrowed or leaky heart valves can make it harder for the heart to pump blood.
- Cardiomyopathy: A disease of the heart muscle itself that affect its ability to pump blood effectively.
- Cardiac arrhythmias: Abnormal heart rhythms can disrupt the heart’s pumping ability.
