目的研究分析经皮冠状动脉介入治疗对冠心病合并左心功能不全患者心功能的影响。方法 86例冠心病合并左心功能不全患者,根据随机数字表法分为观察组与对照组,各43例。观察组给予经皮冠状动脉介入方案治疗,对照组给予常规方案治疗。比较两组患者治疗后心功能改善情况。结果观察组患者左室舒张末内径(LVEDd)、左室收缩末内径(LVEDs)、左室射血分数(LVEF)及左室短轴缩短率(FS)变化情况均显著优于对照组,心功能分级改善情况优于对照组,差异具有统计学意义(P<0.05)。结论对于冠心病合并左心功能不全患者应用经皮冠状动脉介入治疗可有效提高患者的临床治疗效果。
Objective To study the influence of percutaneous coronary intervention on cardiac function in patients with coronary heart disease complicated with left ventricular dysfunction. Methods Eighty-six patients with coronary heart disease complicated with left ventricular dysfunction were divided into observation group and control group according to random number table method, 43 cases in each group. The observation group was treated with percutaneous coronary intervention and the control group with conventional treatment. The improvement of cardiac function was compared between the two groups after treatment. Results The changes of left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (FS) in observation group were significantly better than those in control group The improvement of function grading was better than that of control group, the difference was statistically significant (P <0.05). Conclusion The application of percutaneous coronary intervention in patients with coronary heart disease complicated with left ventricular dysfunction can effectively improve the clinical effect of the patients.
