摘　　要：目的:研究托伐普坦对心肌梗死后左心室功能不全的疗效,初步探讨其作用机制。方法:随机选取心肌梗死后10周的患者共120例,和健康体检人员30例,分别为心梗组和健康对照组,将心梗组随机分为4个亚组,即安慰剂组、呋塞米治疗组、托伐普坦治疗组和呋塞米+托伐普坦治疗组。所有参与者均行体格检查及超声心动图检查,并抽取静脉血以测定相关生化指标。结果:给药4周后,与安慰剂组相比,托伐普坦治疗组和托伐普坦+呋塞米治疗组的血利钠肽(BNP)均显著降低(P<0.05),左室舒张末期内径和收缩末期内径均显著降低(P<0.05),左室射血分数明显改善(P<0.05)。与安慰剂组相比,对照组的心室重量/体重比值均明显降低(P<0.05),托伐普坦组和托伐普坦+呋塞米治疗组亦显著降低(P<0.05)。但与安慰剂组相比,呋塞米治疗组的上述指标无明显统计学差异(P>0.05)。结论:托伐普坦可改善心肌梗死后左心功能不全,并有抑制心肌重构的作用。Objective：To study the effects of tolvaptan on left ventricular dysfunction after myocardial infarctionand explore the potential mechanisms. Method： There are 120 patients 10 weeks after myocardial infarction and 30 healthy subjects were included in this study. Patients with MI were divided into four subgroups, including placebo group, furosemide group, tolvaptan group, furosemide and tolvaptan group. All the participants underwent physical and echocardiographic examinations. Meanwhile, fasting blood was collected to determine the biochemical parameters. Result： Four weeks after medication, , compared with placebo group, the levels of BNP in plasma were significantly reduced in tolvaptan group （P〈0.05） and furosemide and tolvaptan group （P〈0.05）. Similarl,yL- VEDd and LVESd were significantly reduced in tolvaptan group （P%0.05） and furosemide and tolvaptan group （P〈0.05）, while LVEF was significantly increased and LVM/WT was significantly reduced in tolvaptan group （P〈0.05） and furosemide and tolvaptan group（P〈0.05）. However, compared with the placebo group, there is no significant change of all the above parameters. Conclusion： Tolvaptan may improve left ventricular dysfunction and myocardial remodeling after myocardial infarction.
