JAMA Patient Page. Acute Coronary Syndrome.

ACS includes both unstable angina (increasing chest pain, or chest pain at rest) and myocardial infarction (heart attack). Most cases are caused by a blocked blood vessel in the heart. Because of the blockage, the heart muscle does not get enough blood or oxygen. A Rational Clinical Examination in the November 10, 2015, issue of JAMA provides more information on ACS.

Other risk factors include • High blood pressure • High cholesterol • Cigarette smoking • Diabetes • Increasing age
