病理性Q波对冠状动脉多支血管病变的诊断价值

Diagnostic Value of Pathological Q Wave in Multiple Coronary Artery Disease

目的探讨病理性Q波在冠状动脉多支血管病变中的诊断价值。方法选取我院2016年12月—2017年4月收治的70例经冠脉造影(CAG)检查确诊的冠心病患者为研究对象,按照是否出现病理性Q波分为病理性Q波组(观察组)16例和无病理性Q波组54例(对照组)。以CAG检查为金标准,分析病理性Q波对冠状动脉多支病变的诊断价值。结果观察组的冠脉三支病变多于对照组,单支病变少于对照组,差异有统计学意义(P<0.05)。病理性Q波评价冠脉多支病变的准确度为40.7%。结论病理性Q波的出现与冠脉病变的严重程度密切相关,可作为冠心病危险程度的判定依据。

Objective To evaluate the diagnostic value of pathological Q wave in multiple coronary artery disease. Methods 70 cases of coronary heart disease diagnosed by coronary angiography （CAG） were selected from December 2016 to April 2017 in our hospital. The pathological Q waves were divided into pathological Q wave group （observation group） 16 cases and no pathological Q wave group 54 cases （control group）. The diagnostic value of pathological Q wave for multiple coronary artery disease was analyzed with CAG examination as the gold standard. Results The three lesions of coronary artery in the observation group were more than those in the control group, and the single branch lesion was less than the control group, the difference was statistically significant （P 〈 0.05）. The accuracy of the pathological Q wave to evaluate the multiple coronary artery disease was 40.7%. Conclusion The appearance of pathological Q wave is closely related to the severity of coronary artery disease, which can be used as the basis for determining the risk of coronary heart disease.
