Atrial fibrillation after myocardial infarction

Atrial fibrillation is common in acute myocardial infarction  and is associated with poorer outcomes.

The long-term incidence and prognosis of AF after discharge for MI was evaluated in a study of 271 patients with reduced left ventricular systolic function and no history of AF.

40 percent of individuals developed AF by two years, and many of these episodes were asymptomatic. The development of AF was a significant predictor of adverse outcomes, particularly in individuals whose duration of AF was more than 30 seconds.
