Are stress tests safe?
On One Hand: Stress Test RisksDuring a stress test, the heart rate is increased by exercise or medication, allowing a physician to diagnose potential coronary artery problems. Possible risks of the test include discomfort, a decrease in blood pressure which may cause dizziness, shortness of breath, an abnormal heart rhythm or a heart attack.On the Other: Side Effects Are RareAccording to the National Heart, Lung and Blood Institute, the risks of a serious side effect from a stress test are very low. The risk of a heart attack is about one in every 5,000 tests. Minor side effects, such as dizziness and discomfort, typically stop when the test is completed.Bottom LineA stress test does pose risks, however, they are rare and often minor. MedlinePlus reports that a stress test is an effective way for a physician to diagnose heart problems, allowing potentially life-saving treatment to begin.
