a. 倾向得分logistic回归模型中采用的参数
b. 出院用药情况仅统计于出院后存活的患者
LVEF——左心室射血分数（left ventricular ejection fraction）
BP——血压（blood pressure）
MI——心肌梗死（myocardial infarction）
TIA——短暂性脑缺血发作（transient ischemic attack）
PCI——经皮冠状动脉介入治疗（percutaneous coronary intervention）
CABG——冠状动脉旁路移植术（coronary artery bypass graft）
PM——起搏器（pacemaker）
ICD——植入式心律转复除颤器（implantable cardioverter–defibrillator）
CRT——心脏再同步治疗（cardiac resynchronization therapy）
COPD——慢性阻塞性肺疾病（chronic obstructive pulmonary disease）
ARB——血管紧张素Ⅱ受体拮抗剂（angiotensin-2 receptor blockers）
