Resting Heart Rate and Long-term Outcomes Among the African American Population: Insights From the Jackson Heart Study.

ABSTRACT:

Importance

Increased resting heart rate is associated with worse outcomes in studies of mostly white populations, but its significance is not well established in African Americans persons whose cardiac comorbidities and structural abnormalities differ.

Objective

To study the prognostic utility of heart rate in a community-based African American cohort in the Jackson Heart Study.

Design, setting, and participants

A total of 5261 participants in the Jackson Heart Study, a prospective, community-based study in Jackson, Mississippi, were evaluated. Baseline heart rate was assessed by quintiles and as a continuous variable. All participants with baseline heart rate documented by a 12-lead electrocardiogram without pacing or atrial fibrillation noted on their baseline Jacks
