Background: Since poor pump function and left ventricular dilatation both contribute to the development of heart failure, improving pump function and limiting left ventricular dilatation are both important therapeutic targets. The aim of this study was to investigate the effect of cardiac rehabilitation based on aerobic and aerobic-resistance exercises on the biomechanical function of cardiac myocardium (MI, PCI and CABG).
Methods: In this quasi-experimental study, 51 middle-aged male patients aged 55.73±5.92 were followed by MI, CABG, and PCI randomly and equally in three groups of aerobic training, aerobic-resistance training and control were divided. The experimental groups performed sub-maximal aerobic exercises for 8 weeks. The training protocol consisted of three sessions per week of rehabilitation exercises and each activity session consisted of three sections: warm-up, core activity, and cooling. Aerobic-resistance group In addition to aerobic training, they performed resistance training twice a week for 15 minutes.
Results: Significant improvement in all biomechanical performance indices of myocardium including: ejection fraction (P=0.001), end diastolic volume (P=0.001) and end systolic volume (P=0.001), left ventricular end diastolic (P=0.001), left ventricular end systolic (P=0.001), inter-ventricular septal thickness (P=0.001), and left ventricular posterior wall thickness (P=0.001). Both aerobic and aerobic-resistance training groups were significantly better than the control group. This improvement was more pronounced in the aerobic-resistance group.
Conclusion: Exercise-based cardiac rehabilitation program, especially using aerobic-resistance training for at least 8 weeks, significantly improves the biomechanical function of cardiac muscle in patients.
