Abstract
Inflammatory bowel disease (IBD), comprising ulcerative colitis and Crohn's disease, is characterized by widespread inflammation of the gastrointestinal tract with systemic manifestations. Inflammation is one of the driving forces for the pathogenesis of atherosclerosis and its dreaded complications like myocardial infarction (MI). Yet, the association between IBD and myocardial infarction has not been thoroughly established. Myocardial infarction in IBD patients was predominantly seen in young women during the active disease process. At the same time, elevated levels of C-reactive protein and other pro-inflammatory markers were observed in both IBD and atherosclerosis. Increasing evidence suggests inflammation inhibits fibrinolysis, expresses procoagulants, and suppresses anticoagulants promoting thrombosis formation. Moreover, the alteration of gut microbiota impacts the pathogenesis of inflammation and predisposes one to ischemic heart disease. Accordingly, all IBD patients should be screened and counseled on lifestyle modifications for the traditional risk factors of atherosclerosis. Future researchers should consider conducting more clinical trials on anti-inflammatory medication targeting atherosclerosis and therapeutics, while targeting the gut microbiota to reverse the inflammatory atherosclerotic process.
