房内传导阻滞者缺血性脑卒中相关危险因素观察

Observe the risk factors of ischemic stroke in the patients with intra-atrial block

目的观察房内传导阻滞(IAB)冠心病患者发生缺血性脑卒中(IS)的危险因素。方法60例心电图存在IAB的窦性节律冠心病患者,均行头颅CT、超声心动图及颈部血管多普勒检查,同时回顾分析医疗记录以观察IS的发生以及可能与IS相关的危险因素如高血压、阵发性房颤等的发生情况。并以55例非IAB的窦性节律冠心病患者为对照组。结果存在IAB的窦性节律患者IS发生率较高;与对照组相比,IS相关危险因素如年龄、高血压、阵发性房颤等也有显著关联。结论IAB可能是IS的一个危险因素,其有可能作为预测IS的临床参考指标。

Objective To observe the risk factors of ischemic stroke （IS） in the patient with intra-atrial block （IAB）. Methods Sixty coronary heart disease patients with IAB and fifty-five patients without IAB accepted crinial computer tomography, ultrasonic cardiography （UCG） and neck vascular.Doppler ultrasound examinations. The cardiac rhythm of all the patients enrolled were sinus rhythm. Reviewed the medical records to gain the risk factors which were asscioated with IS, such as hypertention and paroxysmal atrial fibrillation. Compared the data of patients with or without IAB. Results The occurance rate of IS was higher in patients with IAB than in patients without IAB. Conclusion IAB may be a risk factor of IS.
