Registration Number
NCT05213546
Lead Sponsor
Cairo University
Brief Summary

To determine the efficacy of different aerobic exercise training intensities in patients with chronic heart failure.Forty five eligible male patients with chronic heart failure were randomly assigned into three groups( High intensity , moderate intensity and low intensity)groups .

Detailed Description

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 :HIT Group: received High Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months.(n=15) MIT Group: received moderate Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months. .(n=15) LIT Group: 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 .
