目的探讨女性冠心病的心电图及冠脉造影特点。方法对140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270例对比。结果女性心电图阳性率74.2%,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54.3%,男性冠脉造影阳性率68.9%;二者对比差异具有统计学意义(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 investigate the characteristics of ECG and coronary angiography in women with coronary heart disease. Methods The electrocardiogram and coronary angiography results of 140 clinically diagnosed women with coronary heart disease and suspected coronary artery disease were analyzed and compared with 270 male patients examined at the same period. Results The positive rate of female ECG was 74.2%, the positive rate of male was 54.1%. The change of T wave in female was significantly higher than that of male (31.5%). The positive rate of coronary angiography was 54.3% and the positive rate of male coronary angiography was 68.9% The difference was statistically significant (P <0.05). The main coronary lesion was single lesion, followed by three branch and two branch lesion. The lesion was dominated by left anterior descending branch, followed by left circumflex branch, right coronary artery and left main branch. Severe coronary stenosis was significantly lower than the male (P <0.05). Conclusions The positive rate of electrocardiogram in women is high, and T wave changes are common. The positive rate of coronary angiography is low, the number of coronary lesion involvement is lower than that of male, and severe stenosis is significantly lower than that of male (P <0.05). Coronary angiography on the diagnosis of coronary heart disease in women have an important value, but may also cause missed diagnosis of coronary heart disease in women.
