title: Leukocyte ascorbic acid and its relationship to coronary artery disease in man.
abstract: The ascorbic acid level of the leukocytes in patients with coronary artery disease was compared to the ascorbic acid level of the leukocytes in patients without coronary artery disease as demonstrated by coronary arteriography. The leukocyte ascorbic acid level was found significantly lower in patients with coronary arteriography. The leukocyte ascorbic acid level was found significantly lower in patients with coronary atherosclerosis (P < 0.001). There was also significant difference in the leukocyte ascorbic acid levels among patients with abnormal coronary arteriograms who smoked compared to those who did not. The anatomical changes secondary to atherosclerotic disease, and mainly those changes related to the ground substance, have been shown to be the changes that have been observed in patients with ascorbic acid deficiency. From the present study, with its limitations, it is suggested that ascorbic acid may play a role in the pathogenesis of atherosclerosis, and although not implicated as an etiological factor in coronary artery disease, it suggests that a closer look at its possible role in the pathogenesis and progression of coronary artery disease is warranted.
