摘要
目的探讨赘生物（Ｖｅｇ）的经食管超声心动图（ＴＥＥ）特征对感染性心内膜炎（ＩＥ）并发症的预测价值。方法对３２例ＩＥ患者进行ＴＥＥ检查。ＩＥ并发症包括充血性心力衰竭（ＣＨＦ）、栓塞及需要外科治疗。结果ＴＥＥ检查Ｖｅｇ的阳性率为９３．７５％（３０／３２）。随着Ｖｅｇ最大径、活动度、范围和回声强度分级级别的增加，其ＩＥ并发症发生率也随之增加。结论ＩＥ患者各因素与并发症的回归分析表明，Ｖｅｇ的活动度、范围、回声强度、Ｖｅｇ大小的三个测值（长度、宽度、最大径）和瓣膜返流均与ＩＥ并发症呈显著的相关关系，它们均是ＩＥ并发症的独立预测因素（均Ｐ＜０．０５），而患者的年龄和性别均与ＩＥ并发症无显著的相关关系（均Ｐ＞０．０５）。当Ｖｅｇ总体评分≥９～≥１１时，其预测准确性最高（７０％～８０％），其相应的敏感性（６０％～９３．３３％）及特异性（６６．６７％～８６．６７％）也较高。
Objective\ To study the value of predicting the complications of infective endocarditis (IE) depending on transesophageal echocardiography (TEE) characterization of vegetation (Veg). Methods\ 32 patients with IE were examined by TEE. The disease associated complications included congestive heart failure (CHF), embolic events and requiring for surgery. Results\ Positive rate of TEE for Veg was 93.75% (30/32). Increasing morphologic grades of Veg (Veg maximal dimension, mobility, extent and consistency) was associated with increasing frequency of clinical complications. Conclusions\ Stepwise multiple logistic regression analysis revealed that Veg mobility, extent, consistency, all three measures of size (perpendicular dimension, parallel dimension, maximal dimension) and valve regurgitation were significantly correlation with disease associated overall complications (P<0.05 entirely). While Veg scores was ≥9￣≥11, the predictive accuracy was highest (70%￣80%) with higher sensitivity (60%￣93.33%) and higher specificity (66.67%￣ 86.67% ).
