Abstract: To elucidate compositional changes of the cardiac valves in monkey with aging, the authors investigated age-related changes of elements in the four cardiac valves of rhesus and Japanese monkeys and the relationships among elements by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The four cardiac valves of the aortic, pulmonary, mitral, and tricuspid valves were resected from 19 rhesus and 11 Japanese monkeys, ranging in age from 10 d to 33 yr. The element contents were determined by ICP-AES. It was found that the Ca, P, S, and Zn contents were high in the four cardiac valves of the monkeys below 1 yr and thereafter decreased significantly with aging, except for Ca in the mitral valve, for which no significant correlation was found between age and Ca content. The Ca and P contents did not increase in the four cardiac valves at old age. This result revealed that calcification scarcely occurred in the four cardiac valves at old age. With regard to the relationships among elements, it was found that there were significant direct correlations among the Ca, P, S, and Zn contents in all of the four cardiac valves of the monkeys, with two exceptions between P and Zn contents in both the aortic and pulmonary valves. Therefore, as Ca decreased in the four cardiac valves, P, S, and Zn decreased simultaneously in the same cardiac valves. © Copyright 2005 by Humana Press Inc.
