management of arrhythmias in chagas disease varies, depending on the complexity of the patient's arrhythmia (eg, appropriate antiarrhythmic therapy is unlikely in patients with nonsustained vt), the availability of certain diagnostic testing (eg, transvenous cardiac electrophysiology), and when and where the arrhythmia occurred. 53, 135 atrial fibrillation in the acute stage of chagas disease is treated with digoxin for rate control and amiodarone for vagotony suppression; patients with only 3 to 5 minutes of refractory atrial fibrillation are empirically treated with antiarrhythmic drugs. 53, 135, 214 as chagas disease progresses and heart failure develops, atrial fibrillation often requires conversion to pacemaker-mediated heart rate control. 53, 135 prophylactic atrial fibrillation chronic rate control and anticoagulation in patients with atrial fibrillation and dilated cardiomyopathy and/or lv systolic dysfunction are recommended for most patients, based on the risk of thromboembolism, bleeding complications, and other known cardiovascular risk factors. 53, 214 for patients with atrial fibrillation and lv systolic dysfunction, digoxin is no longer recommended 53 and anticoagulation should be considered to prevent stroke and thromboembolic events, depending on the patient's bleeding risk and experience with warfarin, life expectancy, access to anticoagulation, and disease severity. 53, 135, 214

accumulating evidence suggests that chagas disease is associated with an excess of ischemic stroke and other thromboembolic events when compared with age- and sex-matched patients with non-chagas heart disease (figure 2). 58 histological studies show that chronic chagas disease is associated with atherosclerosis in coronary arteries, aortic elastic tissue, and arterial vessels of the cerebrovascular system (figure 3). 915 patients with chagas disease who have or are at risk for atrial fibrillation are at increased risk of stroke, and anticoagulation is recommended for these patients with chads2 scores of greater than 2 and high-risk stoke prevention guidelines (see below). 53, 135, 214
