The article by Buresly and colleagues1 adds valuable information about the safety of combining aspirin with thienopyridine derivatives and/or warfarin in elderly patients receiving routine clinical care. Three points are relevant and complementary to the data presented in their study.
First, I could locate only 1 other publication that addresses the use of the 3-drug combination of aspirin, clopidogrel, and warfarin in a nontrial setting.2 This study evaluated outcomes in 66 patients who were given the 3-drug combination following percutaneous coronary intervention with stent placement. Six of these patients had a bleeding event. Of the 6 bleeding events, 4 were serious enough to warrant hospital readmission.2
