Increasing evidence of a link between inflammatory bowel disease (IBD) and adverse cardiovascular events has emerged during the last decade. In 2014, an important number of meta-analyses and cohort studies clarified the subtle dangerous liaisons between gut inflammation and cardiovascular pathology. The evidence suggests that patients with IBD have a significantly increased risk of myocardial infarction, stroke, and cardiovascular mortality, especially during periods of IBD activity. Some populations (e.g., women, young patients) may have an even greater risk. Current effective treatment of IBD is aimed at disease remission and seems to reduce cardiovascular risk in these patients. A beneficial effect was demonstrated for salicylates, but not for steroids or azathioprine. tumor necrosis factor-α antagonists, which are highly effective in the reduction of inflammation and in the restoration of the digestive mucosa, lead to conflicting cardiovascular effects, as they seem to reduce the risk for ischemic heart disease but increase the rate of cerebrovascular events. Future supplemental treatment strategies that may reduce the atherothrombotic risk during periods of IBD activity should be explored.
