缩窄性心包炎(CP)与限制性心肌病(RC)的临床鉴别是非常困难的。常规的体检、ECG,胸片及超声心动图等无创性检查不可靠,即使心导管检查也不能确定舒张期充盈受损是由于心肌病,还是心包增厚所致。明确诊断往往需要开胸手术。近来采用CT显象法,为心包增厚提供了精确的诊断方法。因此本文旨在确定胸部CT是否能准确鉴别心室舒张充盈受损是由缩窄性心包炎还是由限制性心肌病所引起。方法:①病人分三组。A组7例均有CP或/和RC的临床或/和血流动力学的发现;B组5 Clinical differential diagnosis of constrictive pericarditis (CP) and restrictive cardiomyopathy (RC) is very difficult. Non-invasive tests such as routine physical exams, ECGs, chest radiographs, and echocardiography are not reliable, and even cardiac catheterization can not determine whether diastolic filling is due to cardiomyopathy or pericardial thickening. A definite diagnosis often requires a thoracotomy. Recently used CT imaging method for pericardial thickening provides an accurate diagnostic method. Therefore, this article aims to determine whether chest CT can accurately identify ventricular diastolic filling damage is caused by constrictive pericarditis or by restrictive cardiomyopathy. Methods: ① patients divided into three groups. Seven patients in group A had clinical and / or hemodynamic findings of CP or / and RC; Group B 5
