title: Heart rate as a possible therapeutic guide for the prevention of cardiovascular disease.
abstract: Epidemiologic evidence indicates that an elevated heart rate (HR) is an independent predictor of all-cause and cardiovascular (CV) mortality. Ivabradine, a pure HR-lowering agent, reduces CV events in patients with coronary artery disease (CAD) and chronic heart failure, and indicate that an HR greater than 70 b.p.m. is hazardous. These findings demonstrate not only that an elevated HR is an epiphenomenon of CV risk status but also that an elevated HR itself should be a therapeutic target. In addition, recent epidemiologic evidence demonstrates that the in-treatment HR or HR change predicts subsequent all-cause and CV mortality, independent of the HR-lowering strategy. Characteristics of the in-treatment HR or HR change are also important as possible therapeutic guides for risk management. However, there have been concerns regarding deleterious effects on CV event prevention owing to β-blocker-derived pharmacologic HR reduction. The potential role of HR and its modulation should be considered in future guidance documents.
