When the body is active, it requires more oxygen than when it is at rest, and, therefore, the heart has to pump more blood. Because of the increased stress on the heart, exercise can reveal coronary problems that are not apparent when the body is at rest. This is why the stress test, though not perfect, remains the best initial, noninvasive, practical coronary test. The stress test helps doctors determine how well the heart handles the increased demands imposed by physical activity. It is particularly useful for evaluating possible coronary artery disease, detecting inadequate supply of oxygen-rich blood to the tissues of the heart muscle (ischemia), and determining safe levels of exercise in people with existing heart disease.
