Assessment of Dapagliflozin on Vascular Health in Patients With Type 2 Diabetes (SFRNDM2)
Patients with Type 2 Diabetes Mellitus (T2DM) have changes in blood vessel health that can lead to a higher chance of developing heart attacks or strokes. New medications for T2DM including dapagliflozin, which is a Sodium-Glucose Cotransporter-2 inhibitor (SGLT2) inhibitor, may help protect the heart and blood vessels.
The overarching objective of this mechanistic study is to learn how a Sodium-Glucose Cotransporter-2 (SGT2) inhibitor, dapagliflozin, impacts vascular health in patients with Type 2 Diabetes Mellitus (T2DM). The investigators will compare the changes in vascular health to changes in endothelial cell (EC) phenotype including non-coding RNA (ncRNA) to develop evidence supporting the mechanism of cardiovascular benefit of SGLT2 inhibitors. This study will provide novel information regarding the mechanism of effects of novel treatments for endothelial function and vascular health in patients with T2DM to reduce cardiovascular (CV) risk. The research aims to assess the:
- effects of dapagliflozin on EC phenotype.
- impact of dapagliflozin on vasodilator function and additional measures of vascular health including arterial stiffness and circulating markers of vascular health.
