A Heart Attack occurs when blood flow to a part of the heart is suddenly blocked, usually due to a clot in the coronary arteries. This prevents oxygen from reaching heart muscles, causing damage or death of tissue. Common symptoms include chest pain or pressure, shortness of breath, sweating, nausea, and pain in the arm, neck, or jaw. Risk factors include high blood pressure, smoking, diabetes, obesity, and stress. Immediate medical attention is crucial to save life and reduce damage. Healthy lifestyle changes, regular exercise, and proper diet can help prevent heart attacks and improve overall heart health.
