Multiple large trials, such as the AFFIRM, RACE, STAF and PIAF studies, have shown rate control to be comparable with strategies to maintain sinus rhythm in reducing morbidity and mortality in AF. Persistent AF, however, is associated with worsening left-ventricular function and chamber enlargement. Furthermore, these sequelae of AF have clinical consequences, as reduced left-ventricular function can lead to symptomatic heart failure, and atrial dilatation can increase the risk of stroke.
