"Circadian Clock May Contribute to Daily Fluctuation in Risk of Heart Attack and Stroke"

November 8, 2010

Brigham and Women's Hospital Press Release:

Serious adverse cardiovascular events such as heart attack or stroke occur most frequently in the morning. It has been generally assumed that this daily pattern of occurrence is caused (in vulnerable individuals) by the pattern of behaviors that change across the day. Frank Scheer, Ph.D., and Steven Shea, Ph.D. at Brigham and Women’s Hospital (BWH) have now demonstrated that the internal biological clock, or circadian system, regulates several components of the cardiovascular system, suggesting that the circadian system could also be involved in the daily pattern of occurrence of serious adverse events. These findings are published online in November in the Proceedings of the National Academy of Sciences (PNAS).
