目的:验证如下假说:在房颤(AF)患者口服凝血酶抑制剂预防脑卒中(SPOR TIF)III、V试验中卒中和全身性血栓事件(SEE)与血压相关,事件发生率(卒中/SEE、出血)的差异亦与高血压程度相关。方法和结果:采用横断面、纵向分析,资料来源于SPORTIF III、V研究。结果表明,在A F患者中,随收缩压(SBP)的升高,卒中和SEE发生率增高。最高四分位水平SBP与最低四分位水平SBP相比,发生卒中和SEE的H R为1.83(95%CI1.22～2.74), PURPOSE: To verify the hypothesis that stroke and systemic thrombotic events (SEE) are associated with blood pressure in patients with atrial fibrillation (AF) in the oral thrombin inhibitor prophylaxis of stroke (SPOR TIF) III, V event, and incident rates (stroke / SEE , Bleeding) the difference is also related to the degree of hypertension. Methods and Results: The cross-sectional, longitudinal analysis was used and the data were sourced from the SPORTIF III, V study. The results showed that in patients with AF, with the systolic blood pressure (SBP) increased, the incidence of stroke and SEE increased. The highest tertile SBP was 1.83 (95% CI, 1.22 to 2.74) for stroke and SEE compared to the lowest tertile SBP,
