Elevated resting heart rate is an independent risk factor for cardiovascular disease in healthy men and women

A strong, graded, independent relationship between RHR and incident CVD was demonstrated. This was consistent in healthy men and women. We have clarified that the relationship is independent of SBP and that the temporal sequence would be compatible with a causal relationship. New findings include independence from both a validated measure of physical activity and comorbidities and the demonstration of a stronger effect for fatal than nonfatal events, supporting increased arrhythmogenicity of one of the mechanisms.
