本文观察了90例欧洲人和98例班图人心脏的冠状动脉类型和冠状动脉病变。在班图人的心脏中，冠状动脉吻合口血供明显更好。这被发现存在于很小的年龄，与冠状动脉的肥大、动脉粥样硬化或动脉树的大体解剖差异（如左冠状动脉的第三主分支）无关。后者在班图人中（74%）比在欧洲人中（38%）更常见。提示班图族儿童贫血较好的原因可能是其巨幼细胞性贫血和缺铁性贫血的发生率较高。在班图人的心脏中，严重程度的冠状动脉粥样硬化及其并发症的发生率很低。
The coronary arterial pattern and coronary anastomoses have been investigated in 90 European and 98 Bantu hearts. A significantly better coronary anastomotic blood supply has been demonstrated in Bantu hearts. This was found to be present from a very early age onward and not related to hypertrophy, atherosclerosis of the coronary arteries, or to gross anatomic differences of the arterial tree, such as a third primary division of the left coronary artery. The latter was found to be more common (74 per cent) in Bantu than in European hearts (38 per cent). It is suggested that the reason for the better anastomoses might be the high incidence of megaloblastic and iron-deficiency anemia in Bantu children. The low incidence of the severe degrees of coronary atherosclerosis and its complications has been reaffirmed in the Bantu hearts.
