摘要
目的研究静脉应用重组人脑利钠肽(rhBNP)对急性心肌梗死经皮冠状动脉介入治疗(PCI)术后患者心室重塑和左心功能的影响。方法选择48例发病12h内的急性前壁心肌梗死PCI术后患者,随机分为rhBNP组25例和常规治疗组23例,分别于发病后1周、4周和24周采用二维超声心动图测定舒张末期容积指数(LVEDVI)、收缩末期容积指数(LVESVI)、左室射血分数(LVEF)、左室质量指数(LVMI),计算梗死区的局部室壁运动指数(RWMI)。结果两组患者治疗1周时LVEDVI、LVESVI、LVEF、RWMI、LVMI间差异均无显著性意义(P>0.05);治疗4、24周时LVEDVI、LVESVI、LVEF以及治疗24周时RWMI、LVMI间差异均有显著性意义(P<0.05)。结论PCI术后在常规治疗的基础上应用rhBNP可进一步阻抑急性前壁心肌梗死后心室重塑,改善左心功能。
Objective To evaluate the influence of recombinant human brain natriuretic peptide (rhBNP) on ventricular remodeling and ventricular function in patients with acute myocardial nfarction (AMI) after PCI. Methods Total of 48 patients with AMI after PCI were randomly divided into two groups: rhBNP Group (25 cases) and routine treatment group (23 cases). Two dimension echocardiography was used to measure the index of left ventricular end - diastolic volume (LVEDVI) , the index of left ventricular end - systolic volume (LVESVI) , the left ventricular ejection fraction (LVEF) , the index of left ventricular mass (LVMI), the movement index of infarcted regional wall (RWMI). Results LVEDVI, LVESVI, LVEF, RW- MI, LVMI at 1 week after PCI had no significant difference between the two groups, LVEDVI 、 LVESVI 、 LVEF ( at 4 and 24 weeks after PCI) , LVMI, RWMI (at 24 weeks after PCI) in rhBNP group were significantly different from the routine treatment group ( P 〈 0.05 ). Conclusion Transvenous injection of rhBNP combined with other routine treatment can further inhibit the remodeling of left ventricular and improve the left ventricular function.
