Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Investigators will recruit 250 subjects; Group A will consist of 100 prediabetic patients with an A1c of 5.7%-6.4%. Group B will consist of 100 patients with uncontrolled T2D defined as either a) an A1c of 6.5%-7.9% without diabetes medications or b) an A1c ≥ 8.0% with or without diabetes medications. Group C will include 50 participants without T2D or known cardiovascular disease to serve as control comparisons.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with prediabetes have an elevated risk of cardiovascular disease (CVD). Cardiovascular disease (CVD) is also the leading cause of morbidity and mortality in patients with Type 2 Diabetes. There remains an unmet clinical need to identify modifiable risk factors for CVD in patients with disordered glucose homeostasis, including prediabetes and T2D. Exposure to inorganic arsenic and other environmental toxicants may be novel targets for CVD risk reduction for these patients. However, there have been no clinical studies of environmental exposures on vascular function and thrombotic risk among patients with prediabetes and growing understanding of environmental exposures as modifiable risk factors for CVD, and can have an impact by: (1) describing the role of environmental exposures for patients with or at risk for T2D; (2) identifying T2D patients at higher risk for the adverse biological effects of environmental exposures; and (3) informing health policies and treatment pathways to reduce the risk of these exposures.

Investigators will evaluate the association between inorganic arsenic exposure and measures of vascular function, estimate the association between inorganic arsenic exposure and measures of thrombotic risk and will explore the independent association between environmental exposures other than inorganic arsenic and measures of vascular function and thrombotic risk.
