肥厚型心肌病(HCM)以不对称左室肥厚为特征,尤其是非对称型室间隔肥厚(ASH),然而一些高血压病例也有ASH。为了确定原发性高血压(HT)病人的ASH是高血压性左室肥厚的一个类型,还是合并HT的HCM,作者采用放射性核素扫描和右心室心内膜活检,对7例有ASH的HT病人,12例非梗阻性肥厚型心肌病和10例正常人进行了比较研究。
Hypertrophic cardiomyopathy (HCM) is characterized by asymmetric left ventricular hypertrophy, especially asymmetric interventricular septal hypertrophy (ASH), although some cases of hypertension also have ASH. To determine whether ASH in patients with essential hypertension (HT) is a type of hypertensive left ventricular hypertrophy, or HCM with HT, the authors used radionuclide scanning and right ventricular endocardial biopsy to evaluate the effects of ASH HT patients, 12 non-obstructive hypertrophic cardiomyopathy and 10 normal subjects were compared.
