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

Effect of Percutaneous Coronary Intervention on Cardiac Function in Patients with Coronary Heart Disease and Left Ventricular Dysfunction

目的探究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。方法方便择选该院2017年3月-2018年6月收治的冠心病合并左心功能不全患者80例为研究对象,按照完全随机方法 ,分为研究组和对照组两组,每组患者40例。对照组患者全部接受常规治疗方法,研究组患者全部接受经皮冠状动脉介入治疗方法。治疗一段时间后,分别就两组患者的临床治疗有效性、治疗前后的心功能指标与心功能分级情况进行对比。结果两组患者的临床治疗有效性、治疗前后的心功能指标与心功能分级情况的对比结果,研究组均要优于对照组,差异有统计学意义(P<0.05)。其中研究组40例患者中,仅有2例为"无效",治疗有效率为95.0%,而对照组40例患者中,有8例患者为"无效",治疗有效率仅为80.0%(χ~2=4.110,P<0.05),研究组患者接受治疗前,Ⅳ级和Ⅲ级心功能患者分别有13和14例,治疗后减少至1例和3例,而对照组患者接受治疗前,Ⅳ级和Ⅲ级心功能患者分别有14和14例,治疗后仍有8例和10例,差异有统计学意义(χ~2=6.134、4.500,P<0.05)。结论针对冠心病合并左心功能不全患者行以经皮冠状动脉介入治疗方法,可有效提高患者治疗有效率,改善患者心功能情况,具有较高的临床应用价值。

Objective To investigate the effect of percutaneous coronary intervention on cardiac function in patients with coronary heart disease complicated with left ventricular dysfunction. Methods Convenient selected eighty patients with coronary heart disease and left ventricular dysfunction who were admitted to the hospital from March 2017 to June 2018 were selected as subjects. According to a completely randomized method, they were divided into two groups: study group and control group. example. All patients in the control group received conventional treatment, and all patients in the study group underwent percutaneous coronary intervention. After treatment for a period of time, the clinical treatment effectiveness of the two groups of patients, cardiac function indicators before and after treatment and cardiac function grading were compared. Results The clinical efficacy of the two groups of patients, the cardiac function index before and after treatment and the classification of cardiac function, the study group were better than the control group, the difference was statistically significant(P<0.05). Among the 40 patients in the study group, only 2 were "ineffective", and the effective rate was 95.0%. Among the 40 patients in the control group, 8 patients were "ineffective" and the treatment efficiency was only 80.0%(χ~2=4.110,P<0.05), before the treatment group, 13 and 14 patients with grade IV and III cardiac function were treated, and 1 and 3 patients were treated after treatment. The control group received grade IV and III cardiac function before treatment.There were 14 and 14 patients, respectively. There were still 8 and 10 patients after treatment. The difference was statistically significant (χ~2=6.134,4.500,P<0.05). Conclusion Percutaneous coronary intervention for patients with coronary heart disease and left ventricular dysfunction can effectively improve the treatment efficiency of patients and improve the cardiac function of patients. It has high clinical value.
