Quizplus · Accepted Answer

A blood test to measure cardiac enzymes is done to diagnose a myocardial infarction (heart attack). An MI is caused by the death of heart muscle due to decreased blood flow from a blocked coronary artery. Cardiac enzymes are released into the bloodstream when heart muscle cells die, and measuring these enzymes helps to confirm a heart attack has occurred. Congestive heart failure, essential hypertension, and valvular stenosis can also cause damage to the heart muscle but are not typically evaluated by measuring cardiac enzymes.
