Abstract

Antiplatelet therapy is the standard of care for the secondary prevention of acute coronary syndrome and ischemic stroke, especially after coronary intervention. However, this therapy is associated with bleeding complications such as gastrointestinal bleeding, which is one of the most common life-threatening complications. Early endoscopy is recommended for most patients with acute upper gastrointestinal bleeding. After successful endoscopic hemostasis, immediate resumption of antiplatelet therapy with proton-pump inhibitors (PPIs) is recommended to prevent further ischemic events. PPI prophylaxis during antiplatelet therapy reduces the risk of upper gastrointestinal bleeding. The potential negative metabolic interaction between PPIs and clopidogrel is still unclear.

Core tip: Gastrointestinal bleeding (GIB) is a relatively common complication in patients receiving antiplatelet therapy and is associated with an increased risk of recurrent ischemic events and mortality. Early endoscopy is useful for both the diagnosis and the therapeutic management of GIB. Antiplatelet therapy should be resumed immediately after endoscopic hemostasis of GIB, unless the bleeding is life threatening. Prophylaxis with antisecretory drugs such as proton-pump inhibitors reduces the risk of GIB.
