摘　　要：目的使用磁共振成像(MRI)的方法,研究房颤患者无症状脑梗死(ACI)发生率及其危险因素。方法回顾性分析288例房颤患者和262例窦性心律患者的MRI资料,探讨两组ACI的发生率及其影响因素。结果两组ACI的发生率(37.2%vs.35.9%)无统计学差异(P>0.05)。Logistic回归分析显示:高龄、男性、罹患冠心病、糖尿病和高血压病病史的患者均为ACI的高危人群;高胆固醇血症及颈动脉粥样硬化斑块亦为ACI的高危因素。结论与窦性心律相比,房颤患者的ACI发生率无明显增加;控制危险因素可能是ACI防治的重点所在。Objective To explore the incidence and risk factors of asymptomatic cerebral infarction （ACI） in patients with atrial fibrillation （AF） by means of magnetic resonance imaging （MRI）. Methods A retrospective analysis on the MRI data about 288 patients with AF and 262 patients with sinus rhythm （SR） was made, and the incidence and risk factors of ACI in two groups were explored. Results There was no significant difference between the incidences of ACI in the two groups （37.2% vs. 35.9% ;P 〉 0.05）. Logistics regression analysis showed that the aged males and those having a history of coronary heart disease, diabetes or hypertension were high risk population of ACI, and hypercholesterolemia and atherosclerotic plaque were also risk factors for ACI. Conclusion Compared with the patients with SR, the incidence of ACI of the patients with AF does not significantly increased; control over the risk factors may be the key for prevention and treatment of ACI.
