is the test?
- The exercise stress test, also known as the treadmill test
or exercise tolerance test, indicates whether your heart gets
enough blood flow and oxygen when it's working its hardest, such
as during exercise. Often, stress tests are given to people with
chest pain or other symptoms who appear to have coronary artery
disease, based on a medical exam and EKG. In addition, these
tests are sometimes used for other purposes, from assessing the
effectiveness of heart disease treatment to gauging the safety
of a proposed exercise program.
Stress tests are among the best tools for diagnosing heart disease,
and some research suggests that they may also be useful in estimating
disease risk in people who don't have symptoms but have risk
factors such as high cholesterol. If you are over age 40 and
are at risk for coronary artery disease because you smoke or
have high blood pressure or other risk factors, ask your doctor
if you should have this test.
