TORONTO, Oct 5:
Women have a heart health advantage over men as the interplay between female ovarian hormones and a circadian “clock” molecule protects their cardiac health as they age, a study has found.
The findings, published in the journal Cardiovascular Research, could help prevent heart disease as we grow older.
In earlier studies, researchers from University of Guelph in Canada found that heart attacks were worse for males than for females of similar age.
The study also uncovered a time-of-day effect: heart attacks in males were more severe during sleep. This led to the idea that the circadian mechanism – tiny clocks in all of our body’s cells which regulate our 24-hour day and night processes – might work differently in male and female hearts. (PTI)
