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.
Your doctor or cardiologist can take a close look at your heart using an echocardiogram. An echocardiogram is a common ultrasound test that examines your heart and shows its movements. The procedure is helpful in identifying any abnormalities in your heart and heart valves. During the test, sound waves are used to produce images of your heart. An echocardiogram examines: Heart size: The chambers or the muscular walls of your heart may be enlarged due to damaged heart valves, high blood pressure, or other diseases. Heart valves: The test shows whether your valves are shaped normally, whether they open and close correctly, and whether they are leaky.
