  1. Baseline characteristics of patients in the moderate continuous (MCT, n = 24) and high-intensity interval training (HIIT, n = 22) groups. Afib Atrial fibrillation, BMI Body mass index [kg/m2]. Stroke: this illustrates a history of stroke with a current modified Rankin scale of no more than three points. COPD Chronic obstructive lung disease, LTOT Long-term oxygen treatment, NIV Non-invasive ventilation, LVEF Left-ventricular ejection fraction (categorised with eyeballing in transthoracic echocardiography). Valvular dysfunction was defined as at least grade II stenosis or insufficiency on transthoracic echocardiography. Mean values ± standard deviations are depicted. Significance is denoted with an asterisk (p < .05). Differences were assessed with chi-squared/Fisher’s test
