The Relationship Between Increased Epicardial Fat Thickness and Left Ventricular Hypertrophy and Carotid Intima-Media Thickness in Patients With Nonfunctional Adrenal Incidentaloma

Sumario:BACKGROUND: Emerging evidences indicate that patients diagnosed with Adrenal Incidentaloma (AI) may present cardiovascular complications. Epicardial fat thickness (EFT) has recently been described as a new risk factor and an active player in metabolic syndrome and cardiovascular disease. OBJECTIVES: We aimed to evaluate the relationship between EFT and left ventricular hypertrophy and carotid intima-media thickness, which are both strong predictors of cardiovascular morbity and mortality, in patients with nonfunctioning AI. PATIENTS AND METHODS: We evaluated 51 patients (36 females and 15 males) diagnosed with AI and 35 (29 females, 6 males) age, gender and body mass index (BMI) matched healthy controls in terms of cardiovascular risk parameters. Epicardial fat was identified as the echo-free space between the outer wall of the myocardium and the visceral layer of the pericardium. RESULTS: Epicardial fat thickness was significantly higher in patients with AI when compared to the control group (0.89 ± 0.32 cm vs. 0.74 ± 0.26 cm; P = 0.023). left ventricular (LV) mass index and median carotid intima-media thickness (CIMT) were also higher in subjects with AI than in controls (99.8 g/m(2) vs. 86.9 g/m(2); P = 0.024 and 7.5 mm (5.5 - 11.5) vs. 6.5 mm (4.5 - 9.5); P = 0.017). There was a positive correlation between EFT, LV mass index, EFT and CIMT (r = 0.315, P = 0.004; r = 0.363, P < 0.001; respectively). CONCLUSIONS: In this study we showed that EFT, measured by echocardiography is higher in subjects with AI when compared to healthy controls. epicardial fat thickness had the best independent correlation with AI in multiple logistic regression analysis. Incidentaloma is also associated with increased left ventricular mass index and CIMT. Adrenal incidentaloma patients may show early cardiac changes, such as increased left ventricular mass and increased CIMT.
