      Highlights

      • The pancreatic attenuations was correlated with visceral fat and vascular stiffness.
      • Non-obese patients with pancreatic steatosis had increased risk for atherosclerosis.
      • In the obese group, pancreatic steatosis was not associated with atherosclerosis.
      • Our finding highlights the importance of pancreatic fat related to higher risk of CVD.

      Abstract

      Aims

      Evidence that pancreatic fat accumulation has a role in obesity, metabolic syndrome and type 2 diabetes mellitus (DM) is emerging. However, data on the influence of pancreatic steatosis on subclinical atherosclerosis are lacking.

      Methods

      We examined 198 patients with type 2 DM. Pancreatic computed tomography (CT) attenuations were assessed using CT imaging. Obesity was defined as BMI ≥ 25 kg/m2 according to the Asian-specific BMI cut-offs. We defined pancreatic steatosis as pancreatic attenuations below median levels.

      Results

      The pancreatic attenuations was significantly correlated with age (r = −0.302, p < 0.001), visceral fat area (r = −0.194, p = 0.006) and vascular stiffness (r = −0.242, p = 0.001). In the non-obese group (BMI < 25 kg/m2), pancreatic steatosis was associated with a higher prevalence of carotid artery plaque and vascular stiffness. In the non-obese group, patients with pancreatic steatosis, compared with those without, had an odds ratio (OR) of 3.1 (95% CI 1.2–8.1) for carotid atherosclerosis, after adjusting for age, gender and BMI. However, significant associations between pancreatic steatosis and atherosclerosis were not found in the obese group.

      Conclusion

      Ectopic fat in the pancreas is strongly associated with carotid atherosclerosis in non-obese subjects with type 2 DM. This finding highlights the importance of pancreatic fat deposits related to a higher risk of cardiovascular disease, especially in non-obese subjects.
