Which statement about coronary heart disease and stroke are most accurate?
Acute coronary syndrome is a term used to describe a range of conditions associated with sudden, reduced blood flow to the heart. One such condition is a heart attack (myocardial infarction) — when cell death results in damaged or destroyed heart tissue. Even when acute coronary syndrome causes no cell death, the reduced blood flow changes how your heart works and is a sign of a high risk of heart attack. Acute coronary syndrome often causes severe chest pain or discomfort. It is a medical emergency that requires prompt diagnosis and care. The goals of treatment include improving blood flow, treating complications and preventing future problems. SymptomsThe signs and symptoms of acute coronary syndrome usually begin abruptly. They include:
Chest pain or discomfort is the most common symptom. However, signs and symptoms may vary significantly depending on your age, sex and other medical conditions. You're more likely to have signs and symptoms without chest pain or discomfort if you're a woman, older adult or have diabetes. When to see a doctorAcute coronary syndrome is a medical emergency. Chest pain or discomfort can be a sign of any number of life-threatening conditions. Get emergency help for a prompt diagnosis and appropriate care. Do not drive yourself to the hospital.

When a plaque deposit ruptures or splits, a blood clot forms. This clot blocks the flow of blood to heart muscles. When the supply of oxygen to cells is too low, cells of the heart muscles can die. The death of cells — resulting in damage to muscle tissues — is a heart attack (myocardial infarction). Even when there is no cell death, the decrease in oxygen still results in heart muscles that don't work the way they should. This change may be temporary or permanent. When acute coronary syndrome doesn't result in cell death, it is called unstable angina. Risk factorsThe risk factors for acute coronary syndrome are the same as those for other types of heart disease. Acute coronary syndrome risk factors include:
