二尖瓣中、重度反流患者左心射血分数的超声检测可靠性研究

目的]探讨二尖瓣中、重度反流患者左心射血分数的超声检测可靠性。方法]选取2009年1月~2010年1月某院收治的二尖瓣中、重度反流患者50例,均分别采用常规超声检测法检测左心射血分数,同时采用MR测定二尖瓣反流容积。分别按照常规方法计算左心射血分数;常规方法结合MR反流容积修正计算左心射血分数,将两种检测结果分别与临床症状、胸部正位片、心电图检测结果进行符合性检查,综合评价超声检测二尖瓣中、重度反流患者的射血分数在临床诊断、治疗效果评价的可靠性。结果]常规超声检测结合MR检测二尖瓣中、重度反流患者的左心射血分数值与胸部正位片、临床症状、心电图的符合率明显高于单纯的常规超声检测。P﹤0.05,差异有统计学意义。结论]采用常规超声检测联合MR检测,对二尖瓣中、重度患者的左心射血分数测定,所得结果可靠性强,可以真实反应患者的左心收缩功能。

THE RESEARCH FOR THE RELIABILITY OF ULTRASONIC TESTING FOR LEFT VENTRICULAR EJECTION FRACTION IN PATIENTS WITH MITRAL VALVE AND SEVERE REGURGITATION

Objective]To investigate the reliability of ultrasonic testing for left ventricular ejection fraction in patients with mitral valve and severe regurgitation.Methods]50 patients with mitral and severe regurgitation treated in our hospital from January 2009 to January 2010 were chosen as the research subjects.All patients were detected by conventional ultrasonic testing to detect left ventricular ejection fraction.And determined the mitral regurgitation using MR flow volume.Calculated ejection fraction of t...
