本文用超声心动图观察了８０２例吸毒者的心瓣膜及心内膜，对不同的吸毒量、吸毒年限、吸毒方式及不同溶剂进行分析，并与非吸毒者１０３例对照，发现吸毒者心瓣膜或内膜病变３７例（总发生率４．６％），非吸毒者无１例。吸毒者受累心瓣膜为二尖瓣１４例（占３７．８％），主动脉瓣１５例（占４０．５％）．三尖瓣１１例（２９．７％），左室心内膜增厚６例（１６％）。静脉注射者瓣膜病变发生率为４．７％，单纯抽吸者为３．８％；吸毒量≥２．１ｇ／ｄ者瓣膜病变发生率显著高于≤１ｇ／ｄ者（Ｐ＜０．０１）；４例用过污水配制毒品者中，３例确诊为感染性心内膜炎，１例为瓣膜增厚。
In this paper, the heart valve and endocardium of 802 drug addicts were observed by echocardiography. The different drug-taking, drug-taking, drug-taking methods and different solvents were analyzed. Compared with 103 non-drug addicts, heart valve Or endometrial lesions in 37 cases (the overall incidence of 4.6%), non-drug users without one case. 14 cases (37.8%) had mitral valve involvement and 15 cases (40.5%) had aortic valve. Tricuspid valve in 11 cases (29.7%), left ventricular endocardial thickening in 6 cases (16%). The incidence of valvular disease was 4.7% in intravenous injection and 3.8% in simple aspiration, and the incidence of valvular disease was significantly higher than that in ≤1g / d (P <0.01) ). Of the 4 patients who used the waste water to make the drug, 3 cases were confirmed as infective endocarditis and 1 case was valve thickening.
