Gastrointestinal bleeding in cardiac patients

PURPOSE OF REVIEW: Cardiac patients are a fast emerging population vulnerable to gastrointestinal bleeding (GIB) due to their use of antithrombotic medications. This review will quantify the GIB risk of cardiac patients prescribed antithrombotic medications, summarize risk-management strategies and highlight knowledge gaps. RECENT FINDINGS: As the American population ages, it is anticipated that there will be an increased incidence of upper and lower GIB related to age-specific disease, higher burden of comorbidity and increased use of anticoagulants, antiplatelets and aspirin to treat cardiac disease. New evidence has highlighted the significant and clinically relevant GIB risk. The increased use of aggressive antiplatelet and anticoagulant therapies will alter our current understanding of the epidemiology of GIB. SUMMARY: The magnitude of gastrointestinal risk in this vulnerable patient population is still relatively unexplored due to a paucity of literature. This review will highlight changing GIB trends and explore current knowledge regarding GIB risk in cardiac patients. An emphasis on a multidisciplinary approach to the care of these patients will be supported, which involves active patient participation and collaboration between cardiologists and gastroenterologists. Finally, risk-minimization strategies will be suggested and knowledge gaps will be identified.
