Cardiovascular disease is a type of disease that affects the heart and blood vessels. The current care for cardiovascular disease prevention in people with type 1 diabetes is to manage blood pressure, cholesterol blood levels, or manage blood glucose levels.
This study will examine the potential cardiovascular effect(s) of artificial pancreas (AP) technology in patients with type 1 diabetes. AP technology is a system of devices that closely mimics the glucose-regulating function of a healthy human pancreas. It includes an insulin pump and a continuous glucose monitor (CGM). In this study, we will use the Food and Drug Administration (FDA)-approved Tandem t:slim insulin pump with Control-IQ Technology and the FDA approved Dexcom G6 CGM. This study will research whether improvements in blood glucose metrics lead to reductions in some of the cardiovascular biomarkers that represent harmful effects in people with type 1 diabetes. Subjects will be randomly assigned to one of two study groups for 12 weeks—Group 1 will be treated with AP Technology and Group 2 will wear the study CGM and continue to use their current diabetes management strategy (i.e., standard care).
