Effects of Different Exercise Modalities on Cardiopulmonary Function and Pathological Ventricular Remodeling in...

Area of Science:

• Cardiology
• Exercise Physiology
• Rehabilitation Medicine

Background:

• Myocardial infarction (MI) leads to significant cardiopulmonary dysfunction and pathological cardiac remodeling.
• Optimizing exercise interventions is critical for post-MI recovery.
• Current evidence on the comparative effectiveness of different exercise modalities is varied.

Purpose of the Study:

• To evaluate the effects of diverse exercise modalities on cardiopulmonary function in MI patients.
• To assess the impact of exercise on ventricular remodeling post-MI.
• To identify the most effective exercise interventions for cardiac rehabilitation.

Main Methods:

• A systematic review and meta-analysis of 53 studies involving 3170 MI patients.
• Utilized "Netmeta" package in R4.2.2 and "Network" package in Stata15.0 for statistical analysis.
• Study registered in PROSPERO (CRD42024560638).

Main Results:

• Different exercise modes show distinct effects on cardiopulmonary function and cardiac remodeling.
• Moderate-intensity aerobic exercise significantly improved cardiopulmonary function and cardiac remodeling markers.
• High-intensity interval training with resistance training maximized peak oxygen uptake; mind-body exercise enhanced left ventricular ejection fraction and volume.

Conclusions:

• Exercise training generally improves cardiopulmonary health and reduces ventricular remodeling in MI patients.
• Moderate-intensity aerobic exercise offers the greatest overall benefit.
• Individualized exercise prescriptions are essential for tailoring interventions to patient needs and recovery goals.
