Atrial Fibrillation Complicating Acute Coronary Syndromes


Atrial fibrillation frequently complicates myocardial infarction.  Patients with atrial fibrillation complicating acute coronary syndrome have increased morbidity and mortality relative to patients that remain in normal sinus rhythm.  No studies have identified a mortality benefit to rhythm control compared with rate control in the setting of acute coronary syndrome.  Stroke prevention should be pursued with oral anticoagulation therapy, although the majority of patients with atrial fibrillation associated with acute coronary syndrome receive only antiplatelet therapy.  There are several novel oral anticoagulant therapies now available, but these agents have not been well studied in combination with dual antiplatelet therapy.  Therefore, warfarin as part of triple therapy is the most conservative approach until additional data becomes available.
