How does heart attacks kill you?

Heart attacks, or myocardial infarctions, occur when blood flow to a part of the heart is blocked, typically by a blood clot. This blockage deprives the heart muscle of oxygen, leading to tissue damage and potentially causing the heart to stop beating effectively. If the heart cannot pump blood properly, it can result in fatal complications like arrhythmias, cardiac arrest, or severe heart failure. Immediate medical intervention is crucial to restore blood flow and minimize damage.
