The impact of high-intensity interval training on ventricular remodeling in patients with a recent Non ST segment Elevation Acute Myocardial Infarction

Introduction : Exercise-based secondary prevention programs have confirmed improvements in mortality and morbidity in patients with stable coronary heart disease (CHD) and after AMI, respectively. High intensity interval training (HIIT) is more effective at improving V-O2 peak and can be performed safely . our study aimed to determine the impact of HIIT o ventricular remodeling in patients with recent non ST segment myocardial infarction (NSTEMI ) . Methods: sixty-five patients who were suffered from a recent STEMI were randomized to four groups : Group I : re-vascularized and perform HIIT program ,Group II : re-vascularized and not perform HIIT program ,Group III : not re-vascularized and perform HIIT program and Group IV : not re-vascularized and not perform HIIT . Baseline clinical assessment (ie , medical history, physical examination and anthropometric measurements) , transthoracic echocardiography, and cardiopulmonary exercise test ( CPET ) available parameter were performed at baseline and after three months (duration of HIIT program ) . Result : there was significant improvement in CPET parameters in groups that perform HIIT program while no significant changes were obtained according to echocardiographic parameters . conclusion : HIIT program leads to significant improvement in CPET parameters.
