Elevated resting heart rate is an independent, modifiable risk factor for cardiovascular events and mortality in patients with coronary artery disease (CAD). Several mechanisms by which elevated heart rate adversely affects the cardiovascular system are now known. Rates of adequate heart rate control appear to be low in current clinical practice, potentially representing a missed therapeutic opportunity. Drs. Fox and Ferrari discuss the mechanisms that might underlie the involvement of heart rate in CAD and other conditions and review the results of randomized trials that have emphasized its clinical importance.
