急性冠状动脉综合征患者冠状动脉狭窄与心律失常发生的相关性分析

Relationship between coronary artery stenosis of acute coronary syndrome and arrhythmia

目的 研究急性冠状动脉综合征患者的心律失常与冠状动脉狭窄程度的关系。方法 对 10 3例冠状动脉狭窄患者的冠状动脉造影及与心律失常发生的关系进行观察分析。结果 发生各种心律失常者共有 72例 ,其中重度狭窄及完全闭塞的患者中发生心律失常者为 10 0 % (5 8/5 8)、中度狭窄的患者中发生心律失常者为 4 8% (12 /2 5 )、轻度狭窄的患者中发生心律失常者为 13.3% (2 /15 )、而狭窄程度 <5 0 %的患者未发现有心律失常。在心律失常的种类上 ,以右冠状动脉病变为主的患者 ,窦性心动过缓发生率最高占 18.4 5 % (19/10 3)、以左冠状动脉病变为主的患者 ,室性早搏发生率最高占 2 3.3% (2 4 /10 3)。

Objective To investigate the relationship between coronary artery stenosis of acute coronary syndrome and arrhythmia. Methods The data of coronary angiography and arrhythmia in 103 patients were analyzed . Results There were 72 patients with arrhythmia. They include serious stricture and completed obstruction with arrhythmia in 100%(58/58), moderate 48%(12/25), mild 13.3%(2/15), in stricture <50% without arrhythmia. On kind of arrhythmia, sinus bradycardia is the highest in 18.45%(19/103) on the stricture of right cordial artery, premature ventricular contraction is the highest in 23.3%(24/103) on the stricture of left cordial artery. Conclusion Patients with severe coronary artery stenosis had higher incidence of arrhythmia and severe manifisations.
