Elevations in time-varying resting heart rate predict subsequent all-cause mortality in older adults.

ABSTRACT:

Background

An increased resting heart rate (RHR) has long been associated with unhealthy life. Nevertheless, it remains uncertain whether time-varying measurements of RHR are predictive of mortality in older persons.

Design

The purpose of this study was to assess the relationship between repeated measurements of RHR and risk of death from all causes among older adults.

Methods

We evaluated repeat measurements of resting heart rate among 5691 men and women (aged 65 years or older) enrolled in the Cardiovascular Health Study. RHR was measured annually for six consecutive years by validated electrocardiogram. All-cause mortality was confirmed by a study-wide Mortality Review Committee using reviews of obituaries, death certificates and hospital records, interviews with a
