A heart attack occurs when blood supply to the heart is blocked, depriving it of oxygen. Heart attacks are often due to coronary artery disease caused by plaque buildup. Symptoms can be sudden or subtle, making awareness crucial. Key warning signs include chest pain—pressure, tightness, or burning that may radiate to the arms, neck, or back—shortness of breath due to fluid buildup in the lungs, and unexplained cold sweats.
