Angina Pectoris and Heart Attack (Myocardial Infarction) share overlapping symptoms such as Chest pain, Shortness of breath but differ in underlying cause, disease course, and treatment approach. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to coronary artery disease. Stable angina occurs predictably with exertion; unstable angina occurs at rest and is a medical emergency.
Clinical Context
A heart attack occurs when blood flow to part of the heart muscle is blocked, usually by a blood clot in a coronary artery. Immediate treatment is critical. Symptoms include chest pain, pressure radiating to the arm or jaw, sweating, and nausea. Key distinction: Angina Pectoris — Chest pain triggered by exertion or stress, relieved by rest. Heart Attack (Myocardial Infarction) — Chest pain at rest, not relieved by nitrates or rest.
