Cumulative incidence of events within 1 year after cardiac surgery, stratified by type of surgery**
| Event | Cumulative incidence of events % (95% confidence interval) | ||||
|---|---|---|---|---|---|
| CABG n = 52 546 | Single valve n = 10 368 | Multiple valves n = 1309 | CABG + single valve n = 7936 | CABG + multiple valves n = 665 | |
| Disability | 4.6 (4.4–4.8) | 6.5 (6.1–7.0) | 9.0 (7.5–10.7) | 9.0 (8.4–9.7) | 13.1 (10.6–15.8) |
| Death | 3.5 (3.3–3.7) | 5.2 (4.8–5.6) | 10.7 (9.1–12.5) | 9.2 (8.6–9.9) | 14.1 (11.6–16.9) |
| Disability or death | 7.3 (7.1–7.6) | 10.4 (9.8–11.0) | 17.4 (15.4–19.5) | 16.4 (15.6–17.2) | 23.8 (20.6–27.1) |
| Stroke | 1.5 (1.4–1.6) | 2.5 (2.2–2.8) | 3.7 (2.7–4.8) | 3.5 (3.1–4.0) | 5.7 (4.1–7.7) |
| ≥ 3 nonelective hospital admissions | 2.8 (2.6–2.9) | 3.5 (3.2–3.9) | 4.4 (3.3–5.6) | 4.7 (4.3–5.2) | 6.2 (4.5–8.2) |
| Long-term care admission | 0.7 (0.6–0.7) | 1 (0.8–1.2) | 1.5 (1.0–2.3) | 1.5 (1.3–1.8) | 1.8 (1.0–3.0) |
Note: CABG = coronary artery bypass grafting.
* Comparisons between surgery type yielded p < 0.001 for all variables.
