Data are presented as mean ± standard deviation for continuous variables with normal distribution, or median (interquartile range 25% - 75%) for continuous variables with non-normal distribution. Categorical variables are presented as absolute numbers (percentage). COPD: chronic obstructive pulmonary disease; SBP: systolic blood pressure; DBP: diastolic blood pressure; HR: heart rate; LVDD: left ventricular diastolic diameter; LA: left atrium; LVEF: left ventricular ejection fraction; PAP: pulmonary artery pressure. 366
