Frequency, Trend, Predictors, and Impact of Gastrointestinal Bleeding in Atrial Fibrillation Hospitalizations
Atrial fibrillation (AF) is associated with a five-fold increased risk of stroke 1. Anticoagulation alone or in combination with other treatment strategies are implemented to reduce the risk of stroke in patients with AF. Gastrointestinal bleeding (GIB) is a common complication of oral anticoagulation (OAC) with a prevalence of 1%-3% in patients on long term OAC2. GIB in AF patients leads to discontinuation of anticoagulation, which can increase the risk of ischemic stroke, subject patients to endoscopic procedures, blood transfusions, and related side effects.

Frequency of and Determinants of Stroke After Surgical Aortic Valve Replacement in Patients With Previous Cardiac Surgery (from the Multicenter RECORD Initiative)
In conclusion, the risk of postoperative stroke after S-AVR in patients with previous cardiac surgery is high and has an impact on the immediate and late mortality. Excessive bleeding requiring blood transfusion and/or reexploration, prolonged cardiopulmonary bypass time, and use of intra-aortic balloon pump were associated with an extremely high rate of stroke.
