Blood tests. When your heart muscle has been damaged, as in a heart attack, your body releases substances in your blood. Blood tests can measure the levels of these substances and show if, and how much of, your heart has been damaged. The most common test after a heart attack checks levels of troponin in your blood.
You had an EKG (electrocardiogram), stress test, or other test with results that suggested heart disease; Cardiac catheterization also might be used if your doctor thinks you have a heart defect or if you're about to have heart surgery. The procedure shows the overall shape of your heart and the four large spaces (heart chambers) inside it.
