Why the study?
Is abnormal sleep duration and quality associated with increased non-invasive markers of sub-clinical cardiovascular disease?
Is abnormal sleep duration and quality associated with increased non-invasive markers of sub-clinical cardiovascular disease?
This systematic review suggests a relationship between abnormal sleep duration and quality and an increased burden of subclinical cardiovascular disease.
Mixed evidence links abnormal sleep to higher subclinical CVD burden; leaves open need for prospective trials on causality and screening.
Overall, our review provided mixed results, which is generally in line with published literature, with most of the studies showing a significant relationship with subclinical CVD, but only some studies failed to demonstrate such an association. Although such mechanistic relationship needs further evaluation in order to determine appropriate screening strategies in vulnerable populations, this review strongly suggested the existence of a relationship between abnormal sleep duration and quality with increased subclinical CVD burden.
