Rate Control Efficacy in Permanent Atrial Fibrillation: A Comparison Between Lenient Versus Strict Rate Control II - RACE II

Description:

Although rate control has been shown to be associated with similar outcomes, as compared with rhythm control in patients with atrial fibrillation (AF), the optimal level of heart rate (HR) control/lowering is unclear. Current guidelines recommend strict rate control, although data to support this approach are lacking. Accordingly, the RACE II trial sought to investigate whether lenient rate control would be noninferior to strict rhythm control in patients with permanent AF.
