Why the study?
Does vital exhaustion interact with endothelial dysfunction and impaired arterial elasticity to promote early atherosclerosis in young healthy adults?
Does vital exhaustion interact with endothelial dysfunction and impaired arterial elasticity to promote early atherosclerosis in young healthy adults?
Vital exhaustion may contribute to early atherosclerosis specifically in individuals with pre-existing endothelial dysfunction or impaired arterial elasticity.
May link vital exhaustion to early atherosclerosis only in those with lowest FMD or CAC; hypothesis-generating for interactions in young adults.
This study aims to explore the interactive effect of vital exhaustion (VE) and endothelial dysfunction on preclinical atherosclerosis, assessed by carotid intima-media thickness (IMT). Furthermore, interaction between VE and carotid elasticity is examined. Participants were 1,596 young healthy adults from the Cardiovascular Risk in Young Finns study. Endothelial dysfunction was measured by brachial flow-mediated dilatation (FMD), and carotid elasticity by carotid artery compliance (CAC). Significant interactions between FMD and VE, and between CAC and VE, for IMT were found in participants with the very lowest FMD and CAC. Thus, VE may be harmful if the endothelium is not working properly.
