Abstract
Background and purpose: Cardiac remodeling involves changes that manifest clinically as changes in size, shape, and function of the heart after injury. Long-term exercise training has been shown to induce reverse remodeling in patients with stable CHF, improvements in exercise capacity in CHF patients led to increased metabolism, strength and significant reductions in depressive symptoms.Aim of the study: to determine the efficacy of different aerobic exercise training intensities on left ventricular remodeling, prognostic biomarkers in patients with chronic heart failure. Materials and methods: : Forty five eligible male patients with chronic heart failure secondary to ischemic heart disease were selected from National Heart Institute heart failure outpatient clinic , their ages ranged from 50-60 years old and their ejection fraction ranged from 30-40% ,they were randomly assigned into three groups :HITGroup: received High Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months.(n=15) MITGroup: received moderate Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months. .(n=15)LITGroup: received low Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months, Before and after intervention, the following measures were obtained: Echocardiograph parameter (EF%, and left ventricular internal dimension ) , prognostic biomarkers (proBNP), and quality of life
