Individualised dual antiplatelet therapy in a patient with short bowel syndrome after acute myocardial infarction with coronary artery stenting.

Short bowel syndrome after extensive surgical resection of the intestine is characterised by inadequate digestion and absorption of nutrients. Additional clinical problems include impaired absorption and metabolism of diverse drugs requiring individualised medical therapy or alternative treatments. We report a case of individualised dual antiplatelet therapy in a patient who underwent an extensive intestinal resection complicated by acute myocardial infarction requiring percutaneous coronary intervention and stent implantation. Genetic testing of CYP2C19 gene polymorphisms and platelet aggregation testing were used to assess responses to aspirin, clopidogrel, prasugrel and ticagrelor. Given its unique pharmacokinetics with good absorption and without need of metabolism to an active substance, ticagrelor appears to be the best for patients with short bowel syndrome who require dual antiplatelet therapy after coronary stent implantation. 2015 BMJ Publishing Group Ltd.
