  1. Renal function was estimated by levels of the creatinine clearance and binary classified by ≥60 and <60 min/ml
  2. BMI body mass index; BF body fat; LMI lean mass index; HR hazard ratio; CI confidence interval; CAD coronary artery disease; ACS acute coronary syndrome; ACE angiotensin-converting enzyme; ARBs angiotensin-receptor blockers
  3. aRisk factors adjustment included age, sex, medical history (pre-hypertension and pre-diabetes mellitus), heart function (Killip level), severity of CAD (left main artery and three vessel diseases), discharge medication (statin, ACE inhibitors or ARBs and beta-receptor blockers)
