Time of day could have an effect on cardiac health

A new study on mice has found that the time of day could have an effect on a person’s risk of sudden cardiac death. Published in the journal Nature, the researchers from Case Western Reserve University School of Medicine found that levels of a protein which controls the heart’s rhythm fluctuate through the day.

Nearly 300,000 out-of-hospital sudden cardiac arrests occur every year, according to the American Heart Association.
