FRI182 Cardiometabolic Risk And Outcomes In Patient With Adrenal Adenomas

Abstract Disclosure: H. Lam: None. H. Han: None. S. Athimulam: None. Background: Approximately 5% of adults undergoing cross-sectional imaging are reported to have an adrenal adenoma. Although most adenomas are considered non-functioning (NFAT), up to 48% can present with mild autonomous cortisol secretion (MACS). Published studies have reported an increased prevalence of cardiometabolic risk factors, cardiac and cerebrovascular events in MACS patients. Objective: To determine the prevalence of cardiometabolic disease and outcomes in a population-based cohort of patients with adrenal adenomas. Design: Retrospective cross-sectional study of patients with adrenal adenomas over a 10-year period (Jan 2012 – Dec 2021). Setting: Academic primary and tertiary care setting. Main outcomes measured: Prevalence of cardiometabolic disease, cardiovascular events requiring procedure (percutaneous coronary intervention, PCI or coronary artery bypass graft, CABG) and cerebrovascular events. MACS was diagnosed based on cortisol level ≥ 1.8cmg/dL after overnight 1mg dexamethasone suppression testing (DST) and NFAT if cortisol < 1.8mcg/dL. Patients who did not undergo 1mg DST were categorized as unknown cortisol status (UCS). Results: Preliminary results include 198 patients with adrenal adenomas [(135 women (67%) with a median age of 67y, 106 Black (54%), 83 White (42%) and 9 other races (4%)]. 74 (37%) were diagnosed with NFAT, 42 (21%) with MACS, and 82 (41%) with UCS. Hypertension (n=163,83%; MACS vs NFAT vs UCS: 23% vs 34% vs 43%) is the most prevalent cardiometabolic risk factor, followed by hyperlipidemia (n=146, 75%; MACS vs NFAT vs UCS: 21% vs 38% vs 41%), prediabetes (n=94, 50%; MACS vs NFAT vs UCS: 18% vs 43% vs 39%) and type 2 diabetes mellitus (n=82,43%; MACS vs NFAT vs UCS: 22% vs 35% vs 43%), respectively. 14% of patients with adrenal adenomas underwent procedures (PCI or CABG) for cardiovascular events (MACS vs NFAT vs UCS: 33% vs 26% vs 41%) and 11% were diagnosed with cerebrovascular events (MACS vs NFAT vs UCS: 29% vs 19% vs 52%). Conclusions: Patients with adrenal adenomas and mild autonomous cortisol secretion (MACS) are at increased risk of cardiovascular events requiring intervention and cerebrovascular events, compared to non-functioning adrenal tumors. 41% (n=82, 61% Blacks, 30% White, 2% Others) of patient population was classified as unknown cortisol status indicating further need to educate health care professionals on evaluation of adrenal adenomas to improve health care outcomes and disparities in management.
