摘要
目的研究二尖瓣关闭不全(mitral insufficiency,MI)患者围术期左心功能改变。方法 (1)术前根据左室舒张末期内径(LVEDD)大小将患者分成A、B 2组。(2)采用超声心动图测量2组患者术前及术后1周、2周、1个月、3个月的左房大小(LAD),左室舒张末期内径(LVEDD),左室收缩末期内径(LVESD),左室射血分数(LVEF),左室短轴缩短率(LVFS)并进行对比分析。结果 2组患者术后LVEDD,LVESD,LAD都有减少趋势(P<0.05);术后1周、2周LVEF,LVFS呈下降趋势(P<0.05)。结论二尖瓣置换术(mitral valve replacement MVR)后1~2周时间左心功能会发生反复。对于心功能NYHA>Ⅱ级,LVEF<60%者应积极调整后手术。
Objective Research the changes of left ventricular function in perioperative in the patients with Mitral insufficiency.Methods (1) Divide the patients into A and B groups according to the left ventricular end-diastolic diameter before operation.(2) Using Echocardiographic to measure the left atrial size(LAD),left ventricular end-diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS) for two groups before o...
