The prognosis of myocardial infarction in patients with rapid atrial fibrillation (RAF) is poorly known. We sought to ascertain if troponin concentrations are associated with a higher risk of major adverse cardiovascular events (MACE) in patients with RAF and chest discomfort suggestive of coronary origin. ⋯ In patients with RAF who complain of chest pain, increased troponin levels are related to adverse cardiovascular outcomes.
