Data are presented as mean±SD, or number (percentage). The P values were calculated using t tests for continuous variables and Fisher exact test tests for categorical variables. ACEI indicates angiotensin‐converting enzyme inhibitor; ARB, angiotensin II receptor blocker; BMI, body mass index; CABG, coronary artery bypass grafting; CAD, coronary artery disease; HDL‐C, high‐density lipoprotein cholesterol; LDL‐C, low‐density lipoprotein cholesterol; LVEF, left ventricular ejection fraction; MI, myocardial infarction; NSTE‐ACS, non–ST‐segment elevation acute coronary syndrome; OCT, optical coherence tomography; PR, plaque rupture; STEMI, ST‐segment elevation myocardial infarction; TC, total cholesterol; TG, triglyceride.
