In a prospective cohort study, we observed that women with a history of irregular cycles have a 28% increased coronary heart disease risk and tended to have a higher type 2 diabetes risk as compared with women who had a regular cycle length of 27 to 29 days. This association could not be explained by metabolic risk factors or altered hormone levels. Copyright © 2010 American Society for Reproductive Medicine, Published by Elsevier Inc.
