Categorical variables are presented as absolute numbers (percentage). P*: To calculate P value, Student t test was used for the variables with normal distribution, Mann-Whitney U test for the variables with non-normal distribution. P value was estimated by use of the chi-square test or Fisher exact test for the categorical variables. COPD: chronic obstructive pulmonary disease; SBP: systolic blood pressure; DBP: diastolic blood pressure; HR: heart rate; LVDD: left ventricular diastolic diameter; LVSD: left ventricular systolic diameter; LA: left atrium; LVEF: left ventricular ejection fraction; PAP: pulmonary artery pressure. 368
