Cardiovascular (heart and blood vessel) disease is the leading cause of death in developed nations. Assessing the heart's function and examining the seriousness of coronary artery (the blood vessels of the heart) disease are the goals of cardiac stress testing. Putting stress on the heart, such as with exercise or certain medications, makes the heart work harder. Under these conditions, myocardial ischemia (diminished blood flow to the heart muscle) may occur. As part of an evaluation for cardiovascular disease in someone with chest pain (in addition to an electrocardiogram [ECG]), cardiac stress testing may be helpful in determining the need for invasive tests such as coronary angiography—visualizing coronary arteries after injecting dye through a cardiac catheter (tube inserted into the heart). The October 15, 2008, issue of JAMA includes an article about cardiac stress testing.
