Even if you’ve never had one yourself, you are probably familiar with the cardiac stress test, in which a person is hooked up to electrodes and asked to walk or jog on a treadmill under medical supervision. It’s a familiar trope in cinema, in which we see the aspiring athlete/aging astronaut/stressed-out executive put through the paces before the serious conversation with the white-coated medical professional.
That’s a fair representation of what an exercise stress test looks like. Health care providers order such tests to look for weakness or abnormalities in the way the heart pumps under stress.
But it may surprise you to learn that physicians don’t regard the stress test as routine. In fact, most physician groups, from the American College of Cardiology to the Society for Vascular Medicine, advise against giving the test to people who don’t show symptoms of heart problems or are in low heart-risk categories. One of the reasons is that they worry about false positives, which can lead to unnecessary treatment, not to mention undue stress.
“The latest recommendations point out that a careful review of the medical literature failed to find any convincing evidence that resting or exercise ECG provided useful information for preventing CVD events in asymptomatic adults,” states an editorial in the August 2018 edition of JAMA Cardiology.
The stress test has its place
Stress tests are commonly ordered by physicians who want a clearer picture of your heart’s strength. The American Heart Association says the test may be called for when a physician seeks to:
- Diagnose coronary artery disease
- Diagnose the causes of chest pain, shortness of breath or lightheadedness
- Recommend a safe level of exercise
- Check the effectiveness of procedures done in patients with coronary artery disease
- Predict the likelihood of risk of a heart attack or other serious heart problems.
So, when is the right time to have an exercise stress test? If you have symptoms of heart problems or have an elevated risk for a serious heart condition and your physician recommends it — that’s when you should have a cardiac stress test.
If you or someone you care about experiences symptoms that could signal heart problems, see your health care provider. You can find a Providence provider in our online directory.
