Abstract:
Objective To explore the independent risk factors for the 1 year stroke event in Chinese patients with atrial fibrillation (AF) and hypertension (HT).Methods Data of AF and HT patients in the Chinese Emergency Atrial Fibrillation Registry Study were retrospectively analyzed.The eligible patients were divided into the stroke group and the non-stroke group according to the result of 1 year follow-up.The predictors for the 1 year stroke event were identified by uni-and multi-variate Cox regression analysis with the baseline and therapeutic variables.Results A total of 1 118 AF and HT patients were enrolled in the study with the incidence of 1 year stroke event of 8.7％.All patients were divided into the stroke group (n =97) and the non-stroke group (n =1 021).Compared with the non-stroke group,more female patients were in the stroke group (68.0％ vs 54.5％,P ＜ 0.05) and the patients in the stroke group were older [(76.0 ± 9.4) years vs (71.9 ± 10.6) years,P ＜ 0.01] with higher proportion of previous history of stroke (38.1％ vs 23.8％,P ＜0.01).More patients were observed on the antihypertensive treatment in the non-stroke group (91.6％ vs 85.6％,P ＜ 0.05),while more patients on statins in the stroke group(45.4％vs 34.5％,P ＜ 0.05).Multi-variate Cox regression analysis showed that age (HR =1.036,95％ CI 1.010-1.062),female (HR =1.908,95％ CI 1.170-3.110),previous stroke history (HR =1.680,95％ CI 1.084-2.603),and no antihypertensive treatment (HR =1.955,95％ CI 1.008-3.791) were independent risk factors for the 1 year stroke event in patients with AF and HT.Conclusion Age,female,previous stroke history and no antihypertensive treatment are the independent risk factors for the 1 year stroke event in patients with AF and HT.
