Association of Resting Heart Rate and Temporal Changes in Heart Rate With Outcomes in Participants of the Atherosclerosis Risk in Communities Study.

ABSTRACT: Importance:Time-updated heart rate (HR) and temporal change in HR (ΔHR) are associated with outcome in individuals with established heart failure (HF). Whether these factors are associated with outcomes in a community-based cohort is unclear. Objective:To determine whether the time-updated analysis of resting HR, defined as the most recent HR value measured before occurrence of an event or the end of study, and ΔHR over time are associated with outcomes in a community-based cohort. Design, Setting, and Participants:A total of 15 680 participants were enrolled in the Atherosclerosis Risk in Communities cohort study, with HR recorded at baseline and during 3 follow-up visits from 1987 to 1998, with a median interval between visits of 3.0 (interquartile range, 2.9-4.0) years. The ΔHR was calc
