BACKGROUND: Recent literature has shown an association between atherosclerotic cardiovascular disease and inflammatory bowel disease, potentially mediated through chronic inflammatory pathways. However, there is a paucity of data demonstrating this relationship among young patients with premature atherosclerotic cardiovascular disease. METHODS: Using data from the nationwide Veterans wIth premaTure AtheroscLerosis (VITAL) registry, we assessed the association between extremely premature and premature atherosclerotic cardiovascular disease (age at diagnosis: = 40 years and = 55 years, respectively) and inflammatory bowel disease. Patients were compared with age-matched controls without atherosclerotic cardiovascular disease. Multivariable regression models adjusted for traditional risk factors. RESULTS: We identified 147,600 patients and 9485 patients with premature and extremely premature atherosclerotic cardiovascular disease, respectively. Compared with controls, there was a higher prevalence of overall inflammatory bowel disease among premature (0.96% vs 0.84%; odds ratio [OR] 1.14; 95% confidence interval [CI], 1.08-1.21) and extremely premature (1.36% vs 0.75%; OR 1.82; 95% CI, 1.52-2.17) patients. After adjustment, these associations attenuated in both premature and extremely premature groups (OR 1.07; 95% CI, 1.00-1.14 and OR 1.61; 95% CI, 1.34-1.94, respectively). CONCLUSION: Inflammatory bowel disease is associated with higher odds of extremely premature atherosclerotic cardiovascular disease, especially for those age = 40 years. With increasing age, this risk is attenuated by traditional cardiometabolic factors such as obesity, hypertension, diabetes, smoking, and dyslipidemia. Prospective studies are needed to assess the role of early intervention to decrease cardiovascular risk among young patients with inflammatory bowel disease.
