Abstract
Balancing the safety and efficacy of antithrombotic agents in patients with gastrointestinal disorders is challenging because of the potential for interference with the absorption of antithrombotic drugs and for an increased risk of bleeding. In this Review, we address considerations for enteral antithrombotic therapy in patients with cardiovascular disease and gastrointestinal comorbidities. For those with gastrointestinal bleeding (GIB), we summarize a general scheme for risk stratification and clinical evidence on risk reduction approaches, such as limiting the use of concomitant medications that increase the risk of GIB and the potential utility of gastrointestinal protection strategies (such as proton pump inhibitors or histamine type 2 receptor antagonists). Furthermore, we summarize the best available evidence and potential gaps in our knowledge on tailoring antithrombotic therapy in patients with active or recent GIB and in those at high risk of GIB but without active or recent GIB. Finally, we review the recommendations provided by major medical societies, highlighting the crucial role of teamwork and multidisciplinary discussions to customize the antithrombotic regimen in patients with coexisting cardiovascular and gastrointestinal diseases.
Key points
-
Balancing the safety and efficacy of antithrombotic therapy in patients with gastrointestinal disorders is challenging because of the potential for interference with the absorption of antithrombotic drugs or for an increased risk of bleeding.
-
Various clinical states, including malabsorption syndromes, bariatric surgery, short-bowel syndrome or enteral tube feeding, can influence the absorption and bioavailability of oral antithrombotic agents.
-
Bleeding events are an essential prognosticator in patients with cardiovascular diseases — at times as important as thrombotic events — and using antithrombotic agents in patients at high risk of gastrointestinal bleeding (GIB) is very challenging.
-
Most of the existing models to predict the risk of bleeding in patients with coronary artery disease do not estimate the risk of GIB specifically.
-
Identifying patients at high risk of GIB, modifying the bleeding risk by using gastroprotective agents, and determining the appropriate antithrombotic therapy regimen have crucial roles in preventing GIB.
-
After an episode of acute GIB, determining the duration of antithrombotic therapy interruption and the regimen for re-initiation requires consideration of the balance between the bleeding severity and the risk of thrombotic events.

Review criteria
A diverse group of experts was convened (cardiologists, haematologists, gastroenterologists, bariatric surgeons, neurologists, internists, pharmacists and epidemiologists). A protocol outline was agreed ahead of the literature search. A series of comprehensive literature searches were performed to address several questions. These topics included pharmacokinetics and pharmacodynamics of antithrombotic agents with respect to gastrointestinal absorption impairment with motility problems, oral administration difficulties and tube feeding, and gastrointestinal resection surgery. Separate systematic search queries were prepared for strategies to reduce the risk of gastrointestinal bleeding (GIB) in patients receiving antithrombotic agents, including acid-suppressive medications and modifying antithrombotic regimens. Additional search queries were devised for the management of antithrombotic agents in patients with acute GIB, in those with recent GIB, and in those at high risk of GIB without active or recent bleeding (such as patients with inflammatory bowel disease or gastrointestinal cancer). The patient population, interventions, comparators, outcomes and type of study (PICOS) model was used as a search strategy tool. For efficacy or comparative effectiveness questions, randomized controlled trials and, where appropriate, pooled analyses from randomized controlled trials were prioritized. Medline with the PubMed interface was searched. In addition, a systematic search was conducted with respect to existing guidelines or major society recommendations related to the key questions. The date of the last search was 21 January 2023. Existing recent guidelines were referred to if they addressed a question, instead of duplicating them. Cost-effectiveness is not covered in this Review.
