Cardiac stress tests are diagnostic evaluations that assess how well your heart performs during physical exercise – when it's “stressed.” Some signs of heart disease may not be fully evident when the heart is at rest or during activities that require low levels of exertion, but when exertion levels increase, they can become evident, sometimes even resulting in heart attack. The stress test evaluates how your heart responds to increasing levels of stress in a controlled environment and under the guidance of skilled care providers.
Stress tests can be used for lots of purposes, including:
Prior to the test, your heart will be evaluated, either with an electrocardiogram or with an echocardiogram (called a stress echocardiogram test). During the test, you'll be asked to use a treadmill while electrodes remain attached to your chest to monitor your heart's activity. The speed of the treadmill will be increased until your heart reaches a target zone. If you're having an echocardiogram test, the echocardiogram will be repeated as soon as you dismount from the treadmill.
Depending on the type of stress test you're having, you may have dietary or medication restrictions to follow prior to your test. You should also wear loose-fitting clothing. Patients who can't perform or tolerate exercise will be given controlled doses of IV medication to simulate the effects of physical exercise.
Nuclear stress tests are assessments designed to evaluate how the heart responds to increased physical activity. The tests use a special mildly-radioactive dye to highlight areas of the heart and blood vessels prior to and during the test to identify if any areas are not functioning properly or to look for arterial blockages that are preventing normal blood flow to the heart.
Nuclear stress testing can be used to diagnose several heart-related issues and to monitor their treatment. At our practice, we may use a nuclear stress test to:
