Values are mean (standard deviation) or percentages. P values correspond to chi-square tests for categorical variables, analysis of variance for continuous variables.
BMI = body mass index; LVEF = left ventricular ejection fraction; BPM = beats per minute; BDI= Beck Depression Inventory; ECG=electrocardiogram; CP-LVH = left ventricular hypertrophy by Cornell product
