Baseline characteristics of the entire collective.

(BMI = body mass index, LV EF = left ventricular ejection fraction, AV = aortic valve, PAD = peripheral artery disease, COPD = chronic obstructive pulmonary disease, CAD = cardiac artery disease). Variables are expressed as mean ± standard deviation (median) or percentage (number).（身体质量指数（body mass index，BMI）、左心室射血分数（left ventricular ejection fraction，LV EF）、主动脉瓣（aortic valve，AV）、外周动脉疾病（peripheral artery disease，PAD）、慢性阻塞性肺疾病（chronic obstructive pulmonary disease，COPD）、冠状动脉疾病（cardiac artery disease，CAD））。变量以均值±标准差（中位数）或百分比（例数）的形式表示。
