Systematic quantitative investigations were performed in the coronary arteries of 102 hearts of 36 mammal species with an overall more than tenthousandfold difference of their heart weight. After postmortem coronary angiography with a filling pressure of 100 mm Hg x-rays were taken, and the widest diameters of the coronary artery stems were determined. We found a nearly linear correlation between diameter of a standardized coronary artery and virtual diameter of heart, but the increase in diameter of coronary arteries exceeded somewhat that of the diameter of heart especially for heart weights surmounting 100 g. Perhaps relative enlargement of coronary arteries in the bigger hearts contributes to the prevention of large increase of blood flow velocity.
对36种哺乳动物的102颗心脏的冠状动脉进行了系统的定量研究，这些心脏的重量相差超过一万倍。在尸检冠状动脉血管造影中，注入100毫米汞柱的充盈压力后进行X光拍摄，并确定冠状动脉主干的最宽直径。我们发现标准化冠状动脉直径与心脏虚拟直径之间存在近乎线性的相关性，但冠状动脉直径的增加在一定程度上超过了心脏直径的增加，尤其是对于超过100克的心脏重量。也许较大心脏中冠状动脉的相对增大有助于防止血流速度大幅增加。
