All autopsies on Black patients who died of heart disease at Baragwanath Hospital were examined for the years 1959, 1960 and 1976. The commonest form of heart disease encountered in South African Blacks is undoubtedly hypertensive heart disease and by far the majority of these cases are of essential hypertension. There appears to have been a slight rise in the incidence of hypertension. Rheumatic heart disease is extremely common, and affects young people, who often have advanced valvular lesions by puberty. The incidence of idiopathic cardiomyopathy does not seem to have altered materially, although there has perhaps been a slight drop, which may be accounted for by the tendency of clinicians to place cases of congestive cardiac failure with mild hypertension in the hypertensive group rather than in the idiopathic cardiomyopathy group. There was a significant alteration in the incidence of myocardial infarction; in 1959 and 1960 these cases comprised less than 1% of all cardiac deaths but in 1976 they comprised nearly 12%. There has also been a dramatic fall in the incidence of cardiovascular syphilis.
对1959年、1960年和1976年在巴拉干纳特医院死于心脏病的黑人患者进行了所有尸检。在南非黑人中最常见的心脏病形式无疑是高血压性心脏病，而且到目前为止这些病例中的大多数是原发性高血压。高血压的发病率似乎略有上升。风湿性心脏病极为常见，且影响年轻人，他们在青春期时往往已有严重的瓣膜病变。特发性心肌病的发病率似乎没有实质性变化，尽管可能略有下降，这可能是由于临床医生倾向于将轻度高血压伴充血性心力衰竭的病例归入高血压组而非特发性心肌病组。心肌梗死的发病率有显著变化；1959年和1960年，这些病例占所有心脏死亡病例的比例不到1%，但在1976年，它们占近12%。心血管梅毒的发病率也有显著下降。
