AF = atrial fibrillation, CM = cardiomyopathy, COPD = chronic obstructive pulmonary disease, LVEF = left ventricular ejection fraction, std = standard deviation; Left ventricular function was recorded in recorded in n = 345 in the HTN-group and n = 219 in the patient group without HTN. Data are presented as percentages of patients unless otherwise stated.
