Four Black South African patients, representative of a larger group, are described in detail. The common features were long periods of observation, multiple hospital admissions in both normotensive and hypertensive cardiac failure, hypertensive retinopathy and good renal function. All had been diagnosed as having cardiomyopathy. Two of the patients in a normotensive phase became hypertensive after responding to therapy for heart failure. One patient with malignant hypertension showed the features of idiopathic cardiomyopathy at necropsy. These cases are regarded as evidence in favour of the hypothesis that many cases of cryptogenic heart disease (cardiomyopathy, congestive cardiomyopathy, idiopathic cardiomegaly) are in fact cases of hypertension presenting with normotensive cardiac failure.
详细描述了四名南非黑人患者，他们代表了一个更大的群体。共同特征包括观察期长、在血压正常和高血压性心力衰竭时多次住院、高血压视网膜病变以及肾功能良好。所有患者均被诊断为患有心肌病。两名处于血压正常阶段的患者在心力衰竭治疗有反应后血压升高。一名恶性高血压患者在尸检时表现出特发性心肌病的特征。这些病例被视为支持以下假设的证据：许多原因不明的心脏病（心肌病、充血性心肌病、特发性心脏肥大）实际上是表现为血压正常的心力衰竭的高血压病例。
