  1. Italicized value indicates that blood group A was significantly associated with an elevated risk of HR after AMI in different models
  2. HR, heart rupture; AMI, acute myocardial infarction; OR, odds ratio; CI, Confidence interval; BMI, body mass index; SBP, systolic blood pressure; ESR, erythrocyte sedimentation rate; BNP, brain natriuretic peptide; CTnI, cardiac troponin I; LVEF, left ventricular ejection fraction; pPCI, primary primary percutaneous coronary intervention; GRACE RS, Global Registry of Acute Coronary Events risk score
  3. Variables included in model 1 are blood group A, age, female gender, heart rate at admission, BMI and SBP
  4. Variables included in model 2 are blood group A, age, female gender, ESR, BNP and CTnI
  5. Variables included in model 3 are blood group A, age, female gender and LVEF
  6. Variables included in model 4 are blood group A, age, female gender and no pPCI treatment
  7. Variables included in model 5 are blood group A and the GRACE RS
