Effect of Postprandial Hyperglycemia on Vasculature in Type 1 Diabetes and Healthy Adults

University of Virginia·observational·Posted Jan 29, 2021·Updated Mar 30, 2025

In Brief

An observational study evaluating Mixed Meal for Type 1 Diabetes and Hyperglycemia, Postprandial. Completed, enrolled 36 participants across 1 site.

Detailed Summary

To the investigator's knowledge, there are no data available in the current literature regarding the acute effects of postprandial hyperglycemia and insulin timing on myocardial perfusion in people with type 1 diabetes (T1D). Observational studies using CEU in type 2 diabetes demonstrate that postprandial hyperglycemia determines myocardial perfusion defects. The investigator hypothesizes that the combination of postprandial hyperglycemia and insulin increases pulse wave velocity (i.e., aortic stiffness) and myocardial vasoconstriction, thereby reducing myocardial perfusion in T1D when compared to healthy controls. Furthermore, the investigator hypothesizes in T1D that dosing insulin before meal intake will ameliorate these cardiovascular defects.
