What causes heart attack?
Heart attacks are primarily caused by Lack of blood supply to the heart. This occurs when coronary arteries are narrowed or blocked, leading to reduced blood flow. Heart failure refers to the heart’s inability to pump effectively and is not the primary cause of heart attacks.

Heart attacks are primarily caused by (c) Lack of blood supply to the heart. This occurs when the coronary arteries that supply blood to the heart muscle become narrowed or blocked, often due to the buildup of plaque. This deprives the heart muscle of oxygen and nutrients, leading to tissue damage and potentially a heart attack.
Heart attacks, medically known as myocardial infarctions, are typically triggered by the sudden rupture of a plaque within the coronary artery, leading to the formation of a blood clot that obstructs blood flow. This interruption of blood supply causes damage or death to part of the heart muscle, resulting in a heart attack.
