目的探讨左卡尼汀治疗冠状动脉粥样硬化性心脏病(CHD)心绞痛患者的临床疗效。方法选取2011年12月至2015年6月长春市中心医院收治的194例CHD心绞痛患者作为研究对象,采用随机数字表法将其分为对照组与观察组,各97例。其中对照组患者采用单硝酸异山梨酯联合阿司匹林进行治疗,观察组患者在对照组基础上加用左卡尼汀治疗,比较两组患者的临床疗效、血液流变学变化和左心室射血分数(LVEF)。结果观察组患者治疗的总有效率明显高于对照组,差异有统计学意义(P<0.05);治疗后,观察组患者的全血高切黏度、全血中切黏度、全血低切黏度、血细胞比容均明显低于对照组,差异均有统计学意义(均P<0.05);治疗后,观察组患者的LVEF明显高于对照组,差异有统计学意义(P<0.05)。结论左卡尼汀治疗CHD心绞痛患者临床疗效显著,可有效改善患者血液流变学,提高心脏功能。
Objective To investigate the clinical efficacy of levocarnitine in the treatment of patients with coronary heart disease (CHD) angina pectoris. Methods A total of 194 patients with CHD angina pectoris who were admitted to Changchun Central Hospital from December 2011 to June 2015 were selected as subjects and divided into control group and observation group with 97 cases in each group by random number table. The patients in the control group were treated with isosorbide mononitrate combined with aspirin. The patients in the observation group were treated with levocarnitine on the basis of the control group. The clinical efficacy, hemorheological changes and left ventricular ejection fraction (LVEF). Results The total effective rate of observation group was significantly higher than that of control group (P <0.05). After treatment, the observation group had high blood viscosity, whole blood blood viscosity, low blood viscosity (P <0.05). After treatment, the LVEF in the observation group was significantly higher than that in the control group, the difference was statistically significant (P <0.05). Conclusion L-carnitine treatment of patients with CHD angina significant clinical effect, which can effectively improve the patient’s blood rheology and improve cardiac function.
