Epicardial Adipose Tissue Is Increased in Patients With Inflammatory Bowel Disease

OBJECTIVES: Patients with inflammatory bowel disease (IBD) have high cardiovascular morbidity, and, in general, epicardial adipose tissue thickness is related to atherosclerotic vascular disease. This study aimed to investigate the association between epicardial adipose tissue thickness and carotid intima-media thickness as markers of early atherosclerosis in patients with IBD. METHODS: The study comprised 47 patients with IBD (25 with Crohn disease and 22 with ulcerative colitis) and 35 control participants. In all individuals, epicardial adipose tissue and carotid intima-media thickness values were measured by sonography. RESULTS: The mean age ± SD of the 47 patients with IBD was 42.3 ± 11.2 years, versus 41.4 ± 10.1 years for the control group. The epicardial adipose tissue thickness was higher in both the Crohn disease and ulcerative colitis groups compared to the control group (P < .001), but not the carotid intima-media thickness (P = .695 and .917, respectively). There was a strong positive correlation between the carotid intima-media and epicardial adipose tissue thickness values in the Crohn disease and ulcerative colitis groups (r = 0.757; 95% confidence interval, 0.711-0.901; r = 0.786; 95% confidence interval, 0.364-0.615; both P < .001). However, there was no significant difference between the patients who were in the active and inactive disease periods in both groups in terms of carotid intima-media and epicardial adipose tissue thickness values. CONCLUSIONS: Our findings suggest that epicardial adipose tissue thickness might be a marker for detection of early atherosclerosis in patients with IBD. There was a strong positive correlation between carotid intima-media thickness and epicardial adipose tissue thickness values in the patients with IBD. However, there was no correlation between IBD activity and carotid intima-media or epicardial adipose tissue thickness.
