0525: Gender related differences on cardiac rehabilitation benefits for heart failure

BackgroundFemale heart diseases are underdiagnosed and undertreated. They are also probably under referred to cardiac rehabilitation (CR). The aim of our study is to compare CR benefits between men and women.MethodsA total of 442 patients suffering from heart failure were referred to our center for CR between 2010 and 2014. Only 67 were women (15%). All patients had physical examination, electrocardiogram, echocardiography and a cardio-pulmonary exercise test (CPET) before and at the end of CR.ResultsAge was similar between men and women with 56.8±12.4 versus 56.2±14.5 years (p: NS). Ischemic heart disease was the main etiology for men (57.6%), but not for women (30%, p<0.05).Patient’s CR characteristics are summarized in table.Abstract 0525 – Table: Patient’s clinical, echocardiographic and CPET’s characteristicsMen (n=375)Women (n=67)pBefore CRHeart Rate (bpm)80.3±15.780.3±15.777.3±16.4NSSystolic blood pressure (mmHg)109.8±19102.8±19<0.05Left ventricle Ejection Fraction (%)28.8±8.729.3±8.9NSCPET workload (watts)76±2758.1±20<0.05Peak oxygen uptake:15.6±5.214.7±4.9NS– VO2 max (ml/kg/mn)– % of the normal value56.2±17.863.9±22First ventilatory threshold (VT1) (ml/kg/mn)10.9±3.410.5±4NSAfter CRHeart Rate (bpm)76.8±14.675.4±14.3NSSystolic blood pressure (mmHg)110.4±20.898.5±19.2NSCPET workload (watts)92.5±3267.8±20
