Abstract
In addition to antithrombotic therapy, 2 treatment strategies for inte rmittent atrial fibrillation (AF) are evolving: suppression of AF or c ontrol of the ventricular response during AF. Clinical and echocardiog raphic features that predict recurrent AF may influence the choice of management. In this study, clinical, echocardiographic, and electrocar diographic data from 486 patients with intermittent AF in the Stroke P revention in Atrial Fibrillation studies were analyzed. Patients with intermittent AF were younger (p <0.001), had fewer incidences of syste mic hypertension (p <0.007) and heart failure (p <0.001), and had more recent-onset AF than patients with constant AF. They also had a small er mean left atrial diameter, a lower prevalence of a large (>5 cm) le ft atrium, better left ventricular performance by echo, and less mitra l regurgitation. After a mean follow-up of 26 months, 51% of patients remained in sinus rhythm and 49% of patients developed recurrent AF, i ncluding 12% who had AF, as seen on all follow-up electrocardiograms. Clinical factors predicting recurrent AF were age, heart failure, and myocardial infarction. An enlarged left atrium was associated with rec urrent intermittent AF; an enlarged left ventricle predicted conversio n to constant AF. Thus, clinical and echocardiographic parameters pred ict recurrent AF in patients with intermittent nonvalvular AF.
