ObjectivesNonfunctioning adrenal incidentalomas (NFAIs) are associated with increased cardiovascular risk, but the frequency of masked hypertension (MH) is uncertain in these patients. This study aimed to evaluate the prevalence of MH by ambulatory blood pressure monitoring in patients with NFAIs.MethodsThe study included a total of 85 individuals: 43 patients with NFAIs and 42 controls of similar age, gender, BMI, smoking, and diabetes. The office BP and ABPM parameters of the NFAI and controls were measured. Biochemical, hormonal, and radiological data were obtained retrospectively in the NFAI group.ResultsThere were no statistically significant difference between the NFAI and control groups in relation to the office SBP (134.4 ± 37.2 mmHg vs 133.1 ± 35.8 mmHg, p = 0.273) and office DBP (87.4 ± 14.5 mmHg vs 86.8 ± 13.7 mmHg, p = 0.318). Besides, normal (28% vs 28.6%, p = 0.176) and high normal blood pressure (72% vs 71.4%, p = 0.332) rates were similar. The prevalence of MH was significantly higher in patients with NFAI than in controls (25.5% vs 9.5%, p = 0.037). MH was significantly associated with diabetes odds ratio (OR) = 2.07, p = 0.044, office SBP (OR = 1.41, p = 0.046), smoking (OR = 1.46, p = 0.031), BMI (OR = 1.17, p = 0.037), and morning cortisol (OR = 1.21, p = 0.039).ConclusionThe prevalence of MH in the NFAI patient's was higher than in the control group. Patients with NFAI with high normal blood pressure should be evaluated for MH.© 2021. Royal Academy of Medicine in Ireland.
