感染性心内膜炎的临床与超声心动图诊断

The Clinical Features and Echocardiographic Diagnosis of Patients with Infective Endocarditis

目的 :探讨感染性心内膜炎 (IE)的临床特点及超声心动图 (UCG)的诊断价值。方法 :对 42例IE病人作UCG检查 ,结合临床资料进行分析。结果 :发热 40例 ( 95 .2 % ) ,脾肿大 2 6例 ( 6 1.9% ) ,栓塞 2 4例 ( 5 7.1% ) ;血培养阳性 12例 ( 2 8.6 % ) ;UCG检出瓣膜赘生物 36例 ( 85 .7% ) ,多发生于左心系统 ,尤以主动脉多见 ;有基础心脏病者 2 5例 ( 5 9.5 % ) ;死亡 10例 ( 2 3 .8% )。结论 :UCG不仅可提供IE的病因、病理诊断 ,而且对判断其并发症 ,以及治疗和预后均有重要意义。

Objective:To explore the clinical features of infective endocarditis(IE) and the role of echocardiography in diagnosing IE. Methods:The clinical and echocardiographic data of 42 patients with IE were analysed. Results:The incidence of fever, splenomegaly, embolism and death were 95.2%,61.9%,57.1% and 23.8% repectively. The underlying heart disease was found in 25 patients (59.5%). Blood culture was positive in 12 patients (28.6%). Vegetations were detected by echocardiography in 36 patients (85.7%). Left cardiac valves had high rate of vegetations. Conclusions:The detection of vegetation by using echocardiography is important and significant in diagnosing IE and its complication.
