Table 2.
Incidence rates and adjusted HR of stroke and other clinical events according to AF type in Cox regression analysis.
| Endpoint | Incidence rate (per 100 person-year) | HR (95% CI) | p-value | ||
|---|---|---|---|---|---|
| Paroxysmal AF | Non-paroxysmal AF | unadjusted | clinical variable-adjusted** | ||
| Primary endpoint | |||||
| Stroke | 0.50 | 1.09 | 2.19 (1.42–3.39)* | 2.08 (1.33–3.25) | 0.001 |
| Other clinical endpoints | |||||
| STE | 0.07 | 0.15 | 1.35 (0.40–4.53) | 0.627 | |
| All-cause death | 0.48 | 0.68 | 1.24 (0.75–2.05) | 0.399 | |
| Composite outcome (Stroke, STE, All-cause death) | 1.14 | 2.03 | 1.61 (1.18–2.20) | 0.002 | |
*p < 0.001 for unadjusted HR in stroke risk.
**Adjusted for age, sex, hypertension, diabetes, dyslipidemia, prior stroke/transient ischemic attack, congestive heart failure, prior myocardial infarction/peripheral arterial occlusive disease, and anticoagulant, antiplatelet, statin use.
AF, atrial fibrillation; CI, confidence interval; HR, hazard ratio; STE, systemic thromboembolism.
