女性冠心病心电图及冠脉造影特点与冠状动脉病变的关系

Electrocardiogram Characteristics of Coronary Angiography and Coronary Artery Lesion in Female Patients with Coronary Heart Disease

目的探讨女性冠心病的心电图及冠脉造影特点。方法对88例临床诊断为冠心病和疑为冠心病女性患者的心电图及冠脉造影结果进行分析,并与同期检查的男性患者135例对比。结果女性心电图阳性率75.0%,男性阳性率54.1%;女性T波改变(45.5%)明显高于男性(31.9%);女性冠脉造影阳性率54.5%,男性冠脉造影阳性率68.9%;二者对比均有显著差异(P<0.05)。女性冠脉病变以单支病变为主,其次为三支、双支病变,病变部位以左前降支为主,其次为左回旋支、右冠脉、左主干。冠脉重度狭窄明显低于男性(P<0.05)。结论女性心电图阳性率高,T波改变多见;冠脉造影阳性率低,冠脉病变受累支数低于男性,重度狭窄明显低于男性(P<0.05)。冠脉造影对女性冠心病的诊断有重要价值,但亦可能造成女性冠心病漏诊。

Objective To observe the ECG and coronary arteriongraphy（CAG） in female patients with coronary heart disease（CHD）. Methods The ECG and the results of CAG from 88 female and 135 male patients with known CHD were comparatively analyzed. Results The incidence of ECG in female was 75.0%. while in male was 54.1%. T wave change in female（45.5% ） was significant higher than in male （31.9%）. females had lower incidence of CAG than male patients （54.5%VS68.9%, P 〈 0.05 ）. Single vessel lesion appears more in female group than three, double-vessel lesion, left anterior descending （LAD） is the first struck blood vessel, followed by the left-roundabout, right winner,left main. Conclusion Females had higher incidence of ECG while lower incidence of CAG. The number of coronary lesions in female less than in male and severe stenosis was significantly lower than in male（P 〈 0.05 ）. CAG in the diagnosis of C HD for female has important value, hut also may cause lose diagnosis.
