Research contributors had a mean age of 46 years, no prior medical historical past of heart problems, and had self-reported menstrual cycle size data in the beginning of the examine interval.

Throughout a median follow-up interval of 12 years, researchers famous greater than 1,600 cardiovascular occasions among the many examine contributors.

Upon additional evaluation, the scientists discovered that contributors with menstrual cycles of lower than 21 days or longer than 35 days had a 19% increased threat of coronary heart illness in comparison with girls with common menstrual cycles.
