Which condition is an absolute contraindication to symptom-limited exercise testing?

• A. Acute coronary syndrome in the last week
• B. Chronic kidney disease stage 3
• C. Acute myocarditis or pericarditis
• D. Osteoarthritis

Answer: (C)

The key idea is that exercising places stress on the heart, so doing a symptom-limited test is only safe when the heart isn’t in an acute, high-risk state. Acute myocarditis or pericarditis means the heart muscle or the surrounding lining is inflamed, which can provoke dangerous arrhythmias, reduced pumping ability, or even sudden death during exercise. Because of this immediate risk, acute myocarditis or pericarditis is an absolute contraindication to performing a symptom-limited exercise test. Chronic kidney disease stage 3 and osteoarthritis don’t inherently make the test unsafe; they may affect how the test is conducted or tolerated, but they’re not outright barriers. Acute coronary syndrome within the last week is also high risk and would typically lead to deferral, but the strongest, most direct absolute contraindication among the options is the acute inflammatory cardiac condition, since it directly increases the danger of exercising the heart during the test.
