[The prevalence of atrial cardiomyopathy in patients with different types of acute ischemic stroke and its relationship with cryptogenic stroke].

Objective: To investigate the prevalence of atrial cardiomyopathy in patients with different types of acute ischemic stroke and its relationship with cryptogenic stroke. Methods: Patients with acute ischemic stroke within 7 days of onset who were admitted to the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January to September 2019 were prospectively and consecutively enrolled. All included patients were classified according to TOAST classification of ischemic stroke. Chi-square test was used to compare the prevalence of atrial cardiomyopathy among patients with different TOAST classifications. Multivariate logistic regression model was used to analyze the related factors of cryptogenic stroke. Results: A total of 1 098 patients with acute ischemic stroke were enrolled in the study, including 661 males and 437 females, with a median age [M(Q1,Q3)] of 61 (53, 68) years. The prevalence of atrial cardiomyopathy in patients with cryptogenic stroke[53.5% (46/86)] was higher than that in patients with large artery atherosclerosis [38.0%(63/166), P=0.018] and small vessel occlusion [19.4%(37/191), P<0.001], but was lower than that of patients in the cardioembolic group [97.3% (72/74), P<0.001]. Multivariate logistic regression analysis showed that atrial cardiomyopathy was an associated factor for cryptogenic stroke (OR=2.945, 95%CI: 1.766-4.911, P<0.001). Conclusions: Atrial cardiomyopathy is associated with cryptogenic stroke. The prevalence of atrial cardiomyopathy in patients with cryptogenic stroke is higher than that in patients with large artery atherosclerosis and small vessel occlusion, but lower than that in patients with cardiac embolism.目的： 探讨心房心肌病在不同类型急性缺血性卒中患者中的患病率及其与隐源性卒中的关系。 方法： 连续纳入2019年1—9月在郑州大学第一附属医院神经内科就诊的发病7 d内的急性缺血性卒中患者。所有纳入患者均按照缺血性卒中TOAST分型进行病因学分型。采用χ²检验比较心房心肌病在不同TOAST分型患者中的患病率差异。采用多因素logistic回归模型分析探讨隐源性卒中的相关因素。 结果： 本研究共纳入1 098例急性缺血性卒中患者，男661例，女437例，年龄［M（Q1，Q3）］61（53，68）岁，其中隐源性卒中患者128例（11.7%）。隐源性卒中患者心房心肌病患病率［53.5%（46/86）］高于大动脉粥样硬化组［38.0%（63/166），P=0.018］和小血管闭塞组［19.4%（37/191），P<0.001］，低于心源性栓塞组患者［97.3%（72/74），P<0.001］。多因素logistic回归分析显示心房心肌病是隐源性卒中的相关因素（OR=2.945，95%CI：1.766~4.911，P<0.001）。 结论： 心房心肌病与隐源性卒中有关，隐源性卒中患者心房心肌病的患病率高于大动脉粥样硬化组和小血管闭塞组卒中患者，低于心源性栓塞组患者。.
