Table 4. Univariable Analysis of the Association between Preoperative Coexisting Disease and In-hospital Cardiac Mortality

*P  values are from chi-square tests, except † Fisher exact test.

‡ Poorly controlled hypertension (for details, see Methods).

§ If CHF was present at surgery, the odds ratio for death was 12.0 (P = 0.008), and if the patient had history of CHF more than 12 months before index surgery, the odds ratio for mortality was 1.4 (P = 0.70).

PMI = perioperative myocardial infarction; CI = confidence interval; ECG = electrocardiogram; CAD = coronary artery disease; CHF = congestive heart failure.
