Long‐Term Observed Mortality Rates and Hazard Ratios Stratified by Subgroups
| Subgroup | Subcategory | Observed Event Rate % (95% CI) | Median Follow‐Up Times During the Entire Study Period in Years (25th to 75th Percentiles) | Adjusted HR (95% CI) |
|---|---|---|---|---|
| Prior MI | Presence of prior MI | 74.5 (73.4–75.5) | 3.4 (0.8–8.1) | 1.12 (1.07–1.16) |
| Absence of prior MI | 61.1 (60.3–61.8) | 5.6 (1.3–8.6) | Reference | |
| Sex | Male | 62.6 (61.7–63.5) | 5.2 (1.3–8.6) | 1.18 (1.14–1.23) |
| Female | 67.8 (66.9–68.7) | 4.3 (0.9–8.4) | Reference | |
| DM | Presence of DM | 73.7 (72.7–74.7) | 3.5 (0.8–8.1) | 1.28 (1.23–1.33) |
| Absence of DM | 60.3 (59.5–61.1) | 5.7 (1.4–8.6) | Reference | |
| MI type | STEMI | 53.4 (51.5–55.3) | 7.2 (1.8–8.7) | 0.94 (0.88–1.00) |
| NSTEMI | 66.5 (65.9–67.2) | 4.6 (1.1–8.5) | Reference | |
| Revascularization Status | PCI | 49.3 (48.2–50.4) | 8.0 (3.4–8.8) | 0.64 (0.61–0.67) |
| CABG | 46.4 (44.2–48.6) | 8.2 (3.9–9.0) | 0.61 (0.56–0.66) | |
| Medical management | 78.3 (77.6–79.1) | 2.5 (0.4–7.1) | Reference |
CABG indicates coronary artery bypass grafting; CI, confidence interval; DM, diabetes mellitus; HR, hazard ratio; MI, myocardial infarction; NSTEMI, non–ST‐segment–elevation myocardial infarction; PCI, percutaneous coronary intervention; STEMI, ST‐segment–elevation myocardial infarction.
