Liu J, Walton J, DeVries A, Nelson R. Disruptions of Circadian Rhythms and Thrombolytic Therapy During Ischemic Stroke Intervention Frontiers in Neuroscience. 2021 Jan;15. Abstract Several endogenous and exogenous factors interact to influence stroke occurrence, in turn contributing to discernable daily distribution patterns in the frequency and severity of cerebrovascular events. Specifically, strokes that occur...

Source: HARVARD HEALTH BLOG May 13, 2020 By: Lawrence Epstein, MD, ContributorBy: Syed Moin Hassan, MD, Contributor It’s no accident that most people tend to sleep at night and are awake during the day. Our sleep-wake cycle is determined by our circadian rhythm, the body’s internal clock. Like old-time clocks, this internal clock needs to be reset every day,...

Holmer, B.J., Lapierre, S.S., Jake-Schoffman, D.E. et al. Effects of sleep deprivation on endothelial function in adult humans: a systematic review. GeroScience 43, 137–158 (2021). https://doi.org/10.1007/s11357-020-00312-y Abstract Sleep deprivation is highly prevalent and is associated with increased cardiovascular disease (CVD) morbidity and mortality. Age-related alterations in sleep and chronobiology may exaggerate CVD susceptibility in older individuals. The mechanisms responsible for...
