目的探讨超声心动图对甲状腺功能亢进性心脏病的诊断价值。方法对65例临床确诊的甲状腺功能亢进性心脏病患者进行超声心动图检查。结果心脏扩大45例,占69.2%,以左心扩大为主;室间隔及左室壁肥厚8例,占12.3%;左室收缩减低6例,占9.2%。二尖瓣脱垂6例,占9.2%;二尖瓣返流49例,占75.4%;三尖瓣返流52例,占80%;肺动脉高压47例,占72.3%。另有9.2%的患者出现左房自发性显影现象。结论超声心动图检查是诊断甲状腺功能亢进性心脏病的有效方法。 Objective To investigate the diagnostic value of echocardiography for hyperthyroidism heart disease. Methods 65 cases of clinically diagnosed hyperthyroid heart disease patients were examined by echocardiography. Results The heart enlarged in 45 cases (69.2%). The left ventricular enlargement was predominant. The ventricular septum and left ventricular wall hypertrophy in 8 cases (12.3%) and left ventricular contraction (6%) decreased in 9.2%. Mitral valve prolapse in 6 cases, accounting for 9.2%; 49 cases of mitral regurgitation, accounting for 75.4%; tricuspid regurgitation in 52 cases, accounting for 80%; pulmonary hypertension in 47 cases, accounting for 72.3%. Another 9.2% of patients with left atrial spontaneous development phenomenon. Conclusion Echocardiography is an effective method to diagnose hyperthyroid heart disease.
