Data were analyzed with repeated measures ANCOVAs, adjusting for %LVEF, Stage B etiology in all analyses plus BMI (kg/meter) for inflammation biomarkers. P values represent group x time interactions. ANCOVA = analysis of co-variance; LVEF = left ventricular ejection fraction; BMI = body mass index; SD = standard deviation; LVEF = left ventricular ejection fraction; BMI = body mass index; GQ6 = gratitude questionnaire – 6 item; LTEQ = Leisure-Time Exercise Questionnaire; sTNFr1 = soluble tumor necrosis factor receptor 1; IL-6 = interleukin 6; RMSSD = root mean square successive differences; HF power = high frequency power; SD1 = standard deviation of the distances of the RRi to the slope of the line.
