What does moderate-to-severe angina during a Symptom-Limited Test signal?

• A. No risk.
• B. Significant myocardial ischemia that could worsen with continued exercise.
• C. A benign finding not requiring action.
• D. An indicator of good fitness.

Answer: (B)

The main idea is that angina appearing during a symptom-limited exercise test signals significant myocardial ischemia. When the heart is stressed by exercise and a patient develops moderate-to-severe angina, it means the heart muscle isn’t getting enough blood flow to meet the increased demand. Continuing to exercise in this situation could worsen the ischemia and raise the risk of dangerous events like larger areas of muscle damage or arrhythmias. That’s why this finding prompts stopping the test and reassessing with appropriate treatment or further testing. It’s not a sign of no risk, a benign finding, or good fitness—the presence of significant angina under stress indicates a real safety concern and the need for medical action.
