Acute Coronary Syndrome - Ischemic Heart Disease

Acute coronary syndrome (ACS), formerly referred to as ischemic heart disease, refers to a large spectrum of clinical conditions, including unstable angina and myocardial infarction (MI). ACS is caused by a sudden onset of cardiac tissue ischemia secondary to impaired blood flow. The precipitating event is blockage in the coronary arteries or a mismatch between cardiac tissue demand and supply. The resulting tissue ischemia can cause substernal chest pressure; radiation of pain to the left arm, shoulder, or jaw; shortness of breath; sweating; nausea; and changes on an electrocardiogram (ECG). ACS requires immediate diagnosis and care.
