The problem with plaque: Even lesser amounts are still risky

Known as non-obstructive coronary artery disease, this condition can trigger heart attacks down the road.

Imaging stress tests: A clearer view of your heart's health

Exercise tests may include special scans that evaluate blood flow to your heart.

If you have chest discomfort, shortness of breath, or other symptoms that suggest heart disease, your doctor may recommend a stress test. Plaque buildup in your arteries may be limiting blood flow to your heart, which is more evident when the heart is stressed. In many cases, exercise provides the "stress"—you walk or run on a treadmill or pedal a stationary bike. If you're unable to exercise, a pharmacologic stress test (see box) is a good alternative.
