Improving Coronary Vascular Health in Women

Recruiting now · Phase 2

Conditions studied: HIV-1-infection, Coronary Microvascular Dysfunction, Metabolic Disease

In brief

Women with HIV have an increased risk of having a myocardial infarction (heart attack) as compared to women without HIV. One of the mechanisms underlying the increased risk of myocardial infarction among women with HIV may involve reduced ability to increase blood flow through large and small coronary arteries at times when increased flow of oxygen-carrying blood is needed. We are conducting a study randomizing women with HIV and either diabetes, chronic kidney disease, or both to health education alone or to health education plus referral to see either an Endocrinologist or a Nephrologist in a subspecialty clinic for consideration of treatment with medication in a class known as sodium glucose transporter 2 (SGLT2) inhibitors. SGLT2 inhibitors are clinically approved for use in patients with diabetes or chronic kidney disease but have been shown to be underutilized in people with HIV. One of our key analytic aims will be to test if SGLT2 inhibitor therapy results in improved blood flow through the large and small coronary arteries among women with HIV and either diabetes, chronic kidney disease, or both but who have no history of myocardial infarction. A second aim will be to test if subspecialty clinic referral (with or without SGLT2 inhibitor therapy prescription) results in improved blood flow through the large and small coronary arteries among the same group.
