Effect of phase 2 cardiac rehabilitation on change of body composition in patients with acute myocardial infarction

Abstract

[Purpose]: The aim of this study was to evaluate the effect of phase 2 cardiac rehabilitation on the body composition of patients with acute myocardial infarction (AMI). [Subjects]: One hundred seventy-one AMI patients were enrolled in this study. [Methods]: We separated the patients into two groups according to the status of phase 2 cardiac rehabilitation: reha group (n=112) and non-reha group (n=59). Body composition was measured at discharge and 4 months after discharge. [Result]: Body weight, fat mass and waist circumference of the reha group decreased significantly at 4 months after discharge. Muscle mass and lean body mass in both groups increased significantly at 4 months after discharge. [Conclusion]: This study demonstrated that phase 2 cardiac rehabilitation maintained muscle mass and lean body mass in addition to decreasing body weight and fat mass.
