Effects of a 12-week exercise-based program on the quality of life among myocardial revascularization subjects with normal and reduced left ventricular ejection fraction

Resumen

Background/Aims/: Exercise-based cardiac rehabilitationis an effective and safe therapy to be used in themanagement of clinically stable patients following percutaneouscoronary intervention (PCI) or coronary arterybypass graft (CABG).Objectives: To determine if a 12-week physical exerciseprogram (12-WPEP), after PCI or CABG with differentleft ventricular ejection fraction (LVEF) might improve thehealth-related quality of life (HRQOL).Methods: A prospective, controlled before-after studywas conducted in a cardiac rehabilitation service with a12-WPEP. Each session had a duration between 40 to 60minutes, three times per week. Before and after a 12-WPEPwas evaluated HRQOL using the SF-36 questionnaire.Results: The 12-WPEP improve the HRQOL but did notshow differences among PCI (31 subjects) compared toCABG (18 subjects), regardless of whether the LVEF wasnormal or reduced (p<0.005).Conclusion: 12-WPEP improved HRQOL in both PCI andCABG subjects regardless of LVEF.
