    Abstract:
    To analyze the accumulation of elements in the rami of the coronary arteries, the authors determined element contents in both the coronary arteries and their rami of the Thai by inductively coupled plasma-atomic emission spectrometry. The subjects consisted of 13 men and 6 women, ranging in age from 34 to 83 yr. It was found that a higher accumulation of calcium and phosphorus occurred in the proximal sites of coronary arteries such as the anterior descending, right coronary, left coronary, and circumflex arteries than the distal sites such as the diagonal, lateral, conus, acute marginal, and posterior descending arteries. The accumulation of calcium and phosphorus in the anterior descending and right coronary arteries of the Thai increased remarkably in the fifties, thereafter decreased, and increased again in the eighties. It should be noted that a very high accumulation of calcium and phosphorus in the coronary arteries occurred in the fifties. In regard to relationships among the average contents of elements in the coronary arteries and their rami, it was found that there were very significant direct correlations between calcium and phosphorus contents, between calcium and magnesium contents, and between phosphorus and magnesium contents. These results suggested that as calcium and phosphorus increased in the coronary arteries and their rami, magnesium increased simultaneously in all of the coronary arteries and their rami.
