ConclusionConclusion

Fox K et al. Am Heart J. 2013;166(4):654-661.

Elevated resting heart rate is an important correlate

of outcomes in patients with CAD Heart rate lowering may therefore be expected to

reduce mortality and cardiovascular event rates in

patients with stable CAD SIGNIFY will shed further light on the role of heart

rate lowering with ivabradine in patients with stable

CAD without clinical heart failure The study is expected to end in 2014
