目的观察经皮冠状动脉介入治疗(PCI)前后的冠心病患者左心功能改善与其病变严重程度的关系。方法选择我院心内科成功实施冠状动脉介入治疗的住院患者102例,根据冠脉造影结果用累积积分法显示冠脉狭窄严重程度,根据积分分为高分组和低分组,术前及术后3个月行心脏多普勒超声检查,分别检测EF、E峰、A峰及E/A比值,并进行比较。结果高分组、低分组EF值、E/A比值术后较术前明显提高,且高分组EF值、E/A比值的改善明显高于低分组。结论冠心病患者介入治疗后左心功能较术前有明显改善,且冠脉病变越重,左心功能改善越明显。
Objective To observe the relationship between the improvement of left ventricular function and the severity of the disease in patients with coronary heart disease before and after percutaneous coronary intervention (PCI). Methods A total of 102 hospitalized patients undergoing coronary intervention were successfully enrolled in the Department of Cardiology of our hospital. The severity of coronary artery stenosis was shown by Cumulative Integral Method according to the results of coronary angiography. According to the scores, the severity of coronary artery stenosis was divided into high and low scores, preoperative and postoperative 3 Month Doppler ultrasound examination of the heart, respectively, detection of EF, E peak, peak A and E / A ratio, and compared. Results The scores of high-score group, low-score EF and E / A ratio increased significantly after operation, and the improvement of EF and E / A ratio in high-score group was significantly higher than that of low-score group. Conclusion Left ventricular function in patients with coronary artery disease after interventional therapy was significantly improved compared with preoperative, and coronary lesions more severe, the more obvious improvement of left ventricular function.
