摘要
目的 探讨曲美他嗪治疗不稳定型心绞痛(UAP)的临床疗效及对内皮素(ET)、一氧化氮(NO)的表达影响.方法 随机选择UAP患者80例,入选患者被随机单盲分为曲美他嗪组40例和常规治疗组40例.观察统计两组治疗前1周和治疗结束后1周心绞痛发作次数、自拟的疼痛强度及持续时间记分值,检测治疗前后患者血浆ET和NO水平的变化.结果 曲美他嗪组和常规治疗组比较,治疗后患者疼痛发作频率、疼痛强度及持续时间记分均有明显减少,但曲美他嗪组的疗效比常规治疗组明显,差异有统计学意义(P<0.05). 两组治疗都可改善不稳定型心绞痛患者心电图ST段的偏移,但曲美他嗪组的疗效比常规治疗组显著, 差异有统计学意义(P<0.05).两组都可改善心绞痛患者心电图表现,但差异无统计学意义(P>0.05).两组患者治疗后血浆ET水平明显减低,NO水平明显升高,但曲美他嗪组比常规治疗组显著, 差异有统计学意义(P<0.01).结论 曲美他嗪组对不稳定型心绞痛患者疗效明显升高,这种疗效与改善血管内皮细胞功能有关.
Objective To observe the effects of trimetazidine on plasma concentration of endothelin(ET) and nitric oxide(NO) in patients with unstable angina pectoris(UAP).Methods Randomly selected 80 patients with unstable angina pectoris, patients were randomly divided into trimetazidine group with 40 patients, and conventional treatment group with 40 patients. The clinical effect was observed by the changes of the angina pectoris frequencies and pain period and intensity score per mean day at 1 week pro-treatment and 1 week post-treatment. Plasma concentrations of ET and NO were measured before and after the treatment.Results The frequency, intensity and duration of pain score was significantly reduced in both groups, and the effect of trimetazidine group was obvious than the conventional treatment group, the difference was statistically significant(P<0.05). The two groups can improve the treatment of unstable angina patients ECG ST section of the shift, and the effect of trimetazidine group was obvious than the conventional treatment group, the difference was statistically significant(P<0.05). Two groups of patients can improve angina and ECG, but the difference was not statistically significant(P>0.05). In the two groups, plasma ET was significantly reduced, and plasma NO was significantly elevated,the effect of trimetazidine group was obvious than the conventional treatment group, the difference was statistically significant(P<0.01).Conclusions The effects of trimetazidine on patients with unstable angina pectoris is significantly elevated, and is significantly beneficial to protect the endothelial function.
