Effect of exercise-based cardiac rehabilitation on ejection fraction in XXXX @entity1 : a randomized controlled trial.

@entity1 @entity453 @entity1002 @entity299
BACKGROUND: Exercise training as a part of cardiac rehabilitation aims to restore @entity1 with @entity299 to health. However, @entity1002 ( @entity1002 ) is clinically used as a predictor of long-term prognosis in @entity453 ( @entity453 ) @entity1 , there is a scarcity of data on the effectiveness of exercise-based cardiac rehabilitation on @entity1002 . OBJECTIVE: To investigate the effectiveness of exercise-based cardiac rehabilitation on @entity1002 in early post-event @entity453 @entity1 . @entity1 AND METHODS: In a single blinded, randomized controlled trial, post-coronary event @entity453 @entity1 from the age group of 35-75 years, surgically (Coronary artery bypass graft or percutaneous coronary angioplasty) or conservatively treated, were recruited from Golsar Hospital, Iran. Exclusion criteria were high-risk group (AACVPR-99) @entity1 and contraindications to exercise testing and training. Forty-two @entity1 were randomized either into Study or Control. The study group underwent a 12-week structured individually tailored exercise program either in the form of Center-based (CExs) or Home-based (HExs) according to the ACSM-2005 guidelines. The control group only received the usual cardiac care without any exercise training. @entity1002 was measured before and after 12 weeks of exercise training for all three groups. Differences between and within groups were analyzed using the general linear model, two-way repeated measures at alfa=0.05. RESULTS: Mean age of the subjects was 60.5    8.9 years. There was a significant increase in @entity1002 in the study (46.9    5.9 to 61.5    5.3) group compared with the control (47.9    7.0 to 47.6    6.9) group (P=0.001). There was no significant difference in changes in @entity1002 between the HExs and CExs groups (P=1.0). CONCLUSION: A 12-week early (within 1 month post-discharge) structured individually tailored exercise training could significantly improve @entity1002 in post-event @entity453 @entity1 .
