Which precaution is advised for post-MI exercise?

• A. Begin with low-intensity aerobic exercise and monitor RPE and symptoms, avoid Valsalva during resistance training.
• B. Begin with high-intensity intervals and avoid warm-up
• C. Avoid monitoring RPE
• D. Use Valsalva during resistance training

Answer: (A)

After a myocardial infarction, exercise is prescribed with a gradual, monitored approach to protect the healing heart while rebuilding fitness. Starting with low-intensity aerobic work lets the heart adapt and reduces the risk of ischemia or arrhythmia, while still providing meaningful benefits. Using the rating of perceived exertion gives a practical way to pace activity, especially if medications blunt the heart-rate response, and watching for symptoms such as chest pain, shortness of breath, dizziness, or excessive fatigue lets you adjust immediately. In resistance training, avoiding the Valsalva maneuver is important because holding the breath during lifts can cause large increases in blood pressure and reduce venous return, placing extra strain on the heart. A proper warm-up remains important, and high-intensity intervals are not typically appropriate early in recovery. So beginning with gentle aerobic exercise, monitoring RPE and symptoms, and avoiding breath-holding during resistance work aligns with safe post-MI exercise practice.
