Table 3. Univariable Analysis of Association of Surgical (Duration of Surgery, Fluid Balance), Anesthetic (Intraoperative Hemodynamics), and Laboratory Characteristics with Perioperative Myocardial Infarction

*P  values are from univariable logistic regression analysis. All odds ratios (OR) represent the perioperative myocardial infarction (PMI) group (control group is reference with OR 1.0). ORs are expressed in terms of 1 unit increase, unless otherwise noted (e.g. , the odds of having an MI for patients with preoperative hemoglobin of 13.3 g/dl are estimated to be 18% less than the odds of having an MI for patients with hemoglobin level of 12.5 g/dl).

† ORs expressed as a result of a variable change of 500 ml or 5 units (beats per minute [bpm], min, mmHg).

‡ This analysis is performed only for patients who underwent aortic reconstructive surgery (n = 37).

§ Includes allogeneic and cell-salvaged blood (data for the entire group, n = 107).

∥ Only MI identified within the first 48 postoperative h versus  respective controls were used for these analyses.

CI = confidence interval; SBP = systolic blood pressure; DBP = diastolic blood pressure; MI = myocardial infarction.
