What is the recommended exercise intensity (heart rate maximum) for post-MI or heart failure inpatient rehabilitation?

The recommended exercise intensity for post-myocardial infarction (MI) or heart failure inpatient rehabilitation is typically set to a target heart rate of less than or equal to 120 beats per minute (bpm). This intensity level is considered safe and effective for initiating cardiac rehabilitation for individuals recovering from these conditions.

Staying within this heart rate range allows patients to engage in physical activity that promotes cardiovascular health while minimizing the risk of overexertion and potential adverse cardiac events. Following a heart attack or in the presence of heart failure, the ability to tolerate exercise will vary among individuals, and a heart rate ceiling of 120 bpm reflects a cautious approach to ensure safety during rehabilitation. It also allows for the gradual progression of exercise intensity as the patient's condition improves and they build endurance.

This target heart rate aligns with guidelines from various cardiorehabilitation organizations, emphasizing a careful approach to exercise prescription for patients with compromised cardiac function. It is especially important to monitor heart rate during exercise, as post-MI and heart failure patients may have different thresholds and responses to physical activity compared to the general population.
