Capacity of Human Coronary Arteries

Abstract

A postmortem study of the capacity of the coronary arteries of 100 human hearts is presented. The volume of Schlesinger's barium sulfate-gelatin injection mass entering the coronary arterial tree under standard conditions was taken as a measure of its capacity. The factors analyzed include the weight of the heart in the normal and diseased state, the cross-sectional dimensions of the main coronary arteries near their origins, and the sex, age, and nutrition of the subjects.
