Which symptom is a red flag during post-MI exercise?

• A. Chest pain
• B. Dizziness
• C. Palpitations
• D. Excessive fatigue

Answer: (A)

Chest pain during exercise after a myocardial infarction is a red flag because it directly points to possible myocardial ischemia or reinfarction. If chest pain occurs, stop the activity immediately, rest, and check how you feel—if the pain lasts, worsens, or is accompanied by shortness of breath, sweating, or nausea, seek urgent medical evaluation. This symptom specifically signals the heart isn’t getting enough oxygen, which requires careful medical assessment before continuing any activity. Dizziness, palpitations, and excessive fatigue can occur during rehab for various reasons—blood pressure changes, benign sinus rhythms, or deconditioning. They’re important to monitor and usually warrant stopping the activity and pausing to reassess, but they aren’t as specific to dangerous heart ischemia as new chest pain is, which is why chest pain stands out as the strongest red flag in this context.
