Risk of stroke/systemic embolism according atrial fibrillation type.
| Outcome | No. of events | Incidence per 100py | Hazard ratio (95% CI) | |||
|---|---|---|---|---|---|---|
| Age and sex adjusted | p value | Multivariable adjusted | p value | |||
| Stroke/systemic embolism | ||||||
| Paroxysmal | 52 | 0.8 | Ref | Ref | ||
| Persistent | 27 | 1.0 | 1.22 (0.76; 1.94) | 0.41 | 1.13 (0.69; 1.85) | 0.64 |
| Permanent | 42 | 1.5 | 1.35 (0.88; 2.05) | 0.17 | 1.27 (0.83; 1.95) | 0.28 |
Data are hazard ratios (HR) (95% confidence intervals [CI]). p-values were based on Cox regression models.
No. number, Ref. reference, py patient years.
P-values are based on Cox regression models. Multivariable models were adjusted for age, sex, heart rate and time-updated: smoking status (current vs. history/never smoker), BMI, history of diabetes, history of coronary artery disease, history of hypertension, history of heart failure, history of stroke and/or transient ischemic attack, history of renal failure, oral anticoagulation, antiplatelet therapy, history of pulmonary vein isolation and history of electrical cardioversion.
