左心房增大的独立预后意义还不是十分清楚。该研究旨在探讨接受治疗的老年高血压患者中左心房增大与脑卒中危险的相关性。方法:分析1191例60~90岁老年高血压患者中缺血性脑卒中的发生率。按左心房直径(cm)/体表面积(m~2)指数将患者分为正常心房组和左心房增大组(≥2.4cm/m~2)。结果:在随访期[(9.1±4.9)年,范围0.4~20年]内,139例患者发生了缺血性脑卒中,事件发生率为1.28/100患者年。正常心房组(n=928)中86例出现脑卒中,左心房
The significance of independent prognostic significance of left atrial enlargement is not well understood. The aim of this study was to investigate the association of left atrial enlargement with stroke risk in elderly hypertensive subjects undergoing treatment. Methods: The incidence of ischemic stroke in 1191 elderly hypertensive patients aged 60-90 years was analyzed. According to the left atrium diameter (cm) / body surface area (m ~ 2) index, patients were divided into normal atrium group and left atrium enlargement group (≥2.4cm / m ~ 2). Results: During the follow-up period (range, 9.1 ± 4.9 years, range 0.4 to 20 years), ischemic stroke occurred in 139 patients with an incident rate of 1.28 per 100 patient-years. In the normal atria group (n = 928), 86 patients developed stroke and left atrium
