Abstract

Objective This study aimed to investigate microvascular differences in individuals with obesity at risk for developing cardiovascular disease. Methods In this cross-sectional Netherlands Epidemiology of Obesity study, participant sublingual microcirculation was assessed with a newly developed GlycoCheck software (Microvascular Health Solutions Inc., Salt Lake City, Utah), which integrates red blood cell velocity within the smallest capillaries (4-7 mu m) and feed vessels (>10 mu m). Framingham Risk Score was used to calculate 10-year cardiovascular risk, divided into low-, intermediate-, and high-risk groups. ANOVA was used to evaluate microvascular differences among the groups. Results A total of 813 participants were included. The high-risk group (n = 168) was characterized by differences in the microvasculature compared with the low-risk group (n = 392): the high-risk group had a 49% reduction in the number of smallest capillaries and a 9.1-mu m/s (95% CI: 5.2-12.9) higher red blood cell velocity in the feed vessels. No differences in velocity-corrected perfused boundary regions were found. Conclusions It was observed that, with adding red blood cell velocity to the software, sidestream dark field imaging is able to detect microcirculatory differences in a cohort of individuals with obesity at risk for developing cardiovascular disease.
