Detailed explanation-1: -Heart failure, also known as congestive heart failure, is a condition that develops when your heart doesn’t pump enough blood for your body’s needs. This can happen if your heart can’t fill up with enough blood. It can also happen when your heart is too weak to pump properly.

Detailed explanation-2: -Heart failure is a lifelong condition in which the heart muscle can’t pump enough blood to meet the body’s needs for blood and oxygen.

Detailed explanation-3: -Insufficient blood flow to the heart muscle can lead to symptoms of chest pain (angina). If the coronary artery becomes completely blocked, it will cause a heart attack. During a heart attack, some of the heart muscle can die from a lack of oxygen.
