对９例施行瓣膜置换术（ＶＲ）的患者，在术前和术后早期（１０天）分别采用彩色多普勒超声心动图（Ｄ－ＵＣＧ）和无创心功能仪两项技术进行了心功能检测。结果发现，术后早期心功能有一定程度的改善，各项指标中以彩超射血分数（ＥＦ）、左室短轴缩短率（△Ｄ％）、Ｅ峰加速度（ＥＡＣ）以及无创心功能仪心肌收缩指数（ＨＩ）、等容收缩时间（ＩＣＴ）、和颈动脉搏动图切迹垂直高度与顶峰垂直高度比值（ＰＩ／ＰＣ）为敏感和有效指标，两种无创技术检测的左室收缩和泵血功能参数中以射血时间（ＥＴ）相关性最好（ｒ＝０．４１６，Ｐ＜０．１０）。
Nine patients undergoing valvular replacement (VR) underwent heart function using color Doppler echocardiography (D-UCG) and noninvasive cardiac function before and after surgery (10 days) Detection. The results showed that early postoperative cardiac function improved to some extent. Among the indexes, the indexes of EF, △ D%, EAC and noninvasive cardiac function Myocardial contractile index (HI), isovolumic contractile time (ICT), and carotid pulsatility index notch vertical and vertical peak height ratio (PI / PC) were sensitive and effective indicators of noninvasive technique to detect left ventricular systolic and Pumping blood parameters in the ejection time (ET) correlation is best (r = 0.416, P <0.10).
