Clinical Relevance of Different Training Intensities in Chronic Heart Failure.
- Conditions
- Chronic Heart Failure
- Interventions
- Other: Aerobic exercise training
- 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 .

Group Intervention Description Moderate intensity aerobic training group(MIT) Aerobic exercise training 15 patients who received moderate Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months. High intensity aerobic training group(HIT) Aerobic exercise training 15 patients who received High Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months. Low intensity aerobic training group(LIT) Aerobic exercise training 15 patients who received low Intensity aerobic Training in the form of bicycle ergometer exercise for the lower limbs three times /week for three months
- Primary Outcome Measures
Name Time Method Ejection fraction change from baseline to after 12 weeks represents left ventricular function measured by pulsed echocardiography
pro-brain natriuretic peptide (proBNP) change from baseline to after 12 weeks biomarker for heart failure measured by analysis of venous samples drawn
- Secondary Outcome Measures
Name Time Method Minnesota Living With Heart Failure Questionnaire (MLWHF): change from baseline to after 12 weeks Questionnaire for measuring quality of life of heart failure patients
