Study of the Prevalence of Endogenous Hypercortisolism in Patients With Resistant Hypertension (MOMENTUM)

This is a non-interventional study to assess the prevalence of endogenous hypercortisolism (eHC) in patients with resistant hypertension (rHTN) and will enroll approximately 1000 patients at approximately 45 sites in the United States (US). Each patient will have an initial visit for screening. After eligibility is confirmed, a limited exam will be performed and demographic and medical history will be collected. Non-fasting labs and a urine collection will also be done. A second visit will be a fasting blood draw at 8 AM after taking 1 mg of dexamethasone the night before at 11 PM. Cortisol level and study labs will also be collected. After the lab results are obtained, a third visit will be scheduled only for patients with eHC and will include a non-fasting blood draw at 8 AM and scheduling of a non-contrast CT scan.
