|---|---|---|---|---|---|---|---|---|
| Follow‐up, y | 756.9 | 164.3 | 592.6 | |||||
| Average follow‐up, y | 0.8±0.3 | 0.8±0.3 | 0.8±0.3 | 0.47 | ||||
| Event (n) | Rate (%) | Event (n) | Rate (%) | Event (n) | Rate (%) | |||
| MACE | 164 | 21.7 | 56 | 34.1 | 108 | 18.2 | 1.9 (1.3–2.6) | <0.001 |
| All‐cause mortality | 43 | 5.7 | 13 | 7.9 | 30 | 5.1 | 1.6 (0.8–3.0) | 0.19 |
| Nonfatal MI | 90 | 11.9 | 34 | 20.7 | 56 | 9.4 | 2.2 (1.4–3.3) | <0.001 |
| Nonfatal ischemic stroke | 17 | 2.2 | 7 | 4.3 | 10 | 1.7 | 2.5 (0.9–6.7) | 0.07 |
| TIA | 8 | 1.1 | 1 | 0.6 | 7 | 1.2 | 0.5 (0.02–3.3) | 0.60 |
| Stent thrombosis | 6 | 0.8 | 1 | 0.6 | 5 | 0.8 | 0.7 (0.03–5.2) | 0.84 |
| HEM | 90 | 11.9 | 29 | 17.7 | 61 | 10.3 | 1.7 (1.1–2.7) | 0.02 |
| Gastrointestinal hemorrhage | 42 | 5.5 | 18 | 11.0 | 24 | 4.1 | 2.7 (1.5–5.0) | 0.002 |
| Intracranial hemorrhage | 5 | 0.7 | 0 | 0 | 5 | 0.8 | 0 (0–3.0) | 0.29 |
| Other hemorrhage | 43 | 5.7 | 11 | 6.7 | 32 | 5.4 | 1.2 (0.6–2.4) | 0.53 |
For MACE: 11 patients had 2 nonfatal MI events; 2 patients had 2 nonfatal ischemic stroke events; 1 patient had 2 TIA events. For HEM: 16 patients had 2 events and 1 patient had 4 events. HEM indicates major hemorrhage; IRR, incident rate ratio; MACE, major adverse cardiovascular events; MI, myocardial infarction; PCI, percutaneous coronary intervention; TIA, transient ischemic attack.
