What type of exercises would be least appropriate for a patient with a recent myocardial infarction and an ejection fraction of 45%?

In the context of a patient who has experienced a recent myocardial infarction and has an ejection fraction of 45%, progressive resistive exercises are least appropriate. After a myocardial infarction, patients typically have a reduced tolerance for physical activity due to decreased cardiac output and potential residual heart muscle damage. Engaging in progressive resistive exercises, which involve increasing resistance levels, places additional strain on the cardiovascular system and can elevate heart rate and blood pressure significantly.

This may exceed the safe limits of exertion for someone recovering from a myocardial infarction, especially with a compromised ejection fraction. Consequently, it can pose a risk of cardiac complications or adverse events.

In contrast, light walking, range of motion exercises, and low-intensity aerobic exercises are generally considered safe and beneficial for patients in this stage of recovery. These activities promote circulation, enhance mobility, and support cardiovascular health without unnecessary strain on the heart. Properly tailored exercise programs that prioritize safety are crucial for the recovery of patients following a cardiac event.
