  1. AMI acute myocardial infarction, CI confidence interval, HR hazard ratio, Ref reference category
  2. a Anemia: Hemoglobin (Hb) concentration of < 12 g/dL in women, Hb concentration of < 13 g/dL in men
  3. b Mild anemia: Hb concentration of 11 g/dL to < 12 g/dL in women, Hb concentration of 11 g/dL to < 13 g/dL in men
  4. c Moderate to severe anemia: Hb concentration of < 11 g/dL in men and women
  5. d Non-anemia: Hb concentration of ≥12 g/dL in women, Hb concentration of ≥13 g/dL in men
  6. e Model 1: Adjusted for age and sex
  7. f Model 2: Model 1 + previous myocardial infarction, angina pectoris, hyperlipidemia, diabetes, stroke, eGFR, heart rate, AMI type (STEMI, NSTEMI, Bundle branch block), left-ventricular ejection fraction (LVEF) < 30%, medications at discharge (evidence-based medications (antiplatelet agents, angiotensin-converting-enzyme inhibitor (ACEI), angiotensin-receptor blocker (ARB), beta-blocker, statins), calcium channel blockers, diuretics), percutaneous coronary intervention (PCI) and any in-hospital complication
