Neurovascular-Nuggets (5)_ The Surprising Link Between Long Sleep and Stroke Risk
Episode notes
In an investigation into the cardiovascular health disparities among racially and ethnically diverse populations, the Northern Manhattan Study (NOMAS) examined the correlation between sleep duration and subclinical carotid atherosclerosis, a precursor to stroke. The study controlled for a range of sociodemographic and lifestyle variables. The results, based on 1,553 community-dwelling adults, revealed a pronounced association between long sleep duration (≥9 hours) and increased presence and area of carotid plaque, independent of other risk factors. Conversely, short sleep duration (<7 hours) and daytime sleepiness showed no significant correlation with carotid atherosclerosis markers. These findings suggest that extended sleep duration may serve as an independent risk factor for carotid atherosclerosis, thereby providing a potential mechanistic link between long sleep and elevated stroke risk. The paper also explores potential mechanisms linking sleep duration to carotid atherosclerosis. Long sleep has been correlated with metabolic imbalances, inflammatory markers, and certain behavioral risk factors, all of which are implicated in cardiovascular disease. Despite these observations, causality remains unclear. The study suggests that targeted interventions aimed at sleep duration could serve as a novel pathway to mitigate carotid atherosclerotic burden, although further research is needed to elucidate the underlying mechanisms.
