Angiograms Can Detect Blockages
If someone has symptoms or risk factors for heart disease, a doctor can use different tests to evaluate heart function and detect blockages. Electrocardiograms, or EKGs, can show if the heart has been damaged. Exercise tolerance tests, also know as stress tests, measure the heart's ability to supply the body with oxygen. But for pinpointing blockages, X-ray images called angiograms are essential.
