What condition would contraindicate a regular exercise stress test?

• A. Recent Myocardial Infarction
• B. Beta Agonist Use
• C. Hypertension
• D. Missing an Exercise Prescription

Answer: (A)

When deciding if an exercise stress test is safe, recent myocardial infarction is a critical contraindication because the heart is still healing and more vulnerable to the added stress of exercise. The damaged heart muscle and the potential for ongoing ischemia mean that pushing the heart with a stress test could trigger dangerous events such as arrhythmias, extension of the infarct, or unstable hemodynamics. Therefore, the test is typically deferred in the immediate post‑MI period until the patient has stabilized and any needed revascularization is addressed. In contrast, using a beta agonist can affect heart rate and blood pressure responses during testing, but it does not by itself render the test unsafe. Hypertension by itself is not an automatic contraindication; with proper monitoring and appropriate thresholds, many patients with high blood pressure can safely undergo a stress test. Missing an exercise prescription isn’t a safety issue for the test itself; it relates to planning and supervision, not an inherent risk of testing.
