dc.description.abstractThis paper reviews the work carried out in the Research Centre for Nuclear Microscopy, NUS on the role of iron in coronary heart disease, using the technique of nuclear microscopy to determine the levels of iron and other trace elements in the artery wall and lesions. These investigations have indicated that iron may play a significant role in the development of atherosclerosis, probably through the promotion of cytotoxic free radicals leading to the oxidation of low-density lipoprotein (LDL). Using a rabbit model we have observed that early atherosclerotic lesions, induced by feeding the animals on a 1% cholesterol diet, contain increased levels of iron (up to 8 times) compared with the adjacent healthy artery wall. In a follow-up time sequence study, we have shown that iron accumulation occurs at the onset of lesion formation, which takes place around 4-6 weeks after exposure to the 1% cholesterol diet. As the lesions mature, they enlarge to occupy a significant fraction of the artery wall, and at abou t 16 weeks the lesions begin to show signs of calcification. In an additional experiment, where the cholesterol fed rabbits were kept anaemic through weekly bleeding, the iron content of the artery wall was reduced and the onset of atherogenesis was delayed. In a further investigation, rabbits were fed on a 1% cholesterol diet and after 6 weeks (corresponding to the period of early lesion formation) a test group was subjected to treatment using the iron chelator desferal. Preliminary results indicate that during the treatment with desferal, lesion development was slowed down. © 2001 Elsevier Science B.V. All rights reserved.
