Heart Rate Response to a Timed Walk and Cardiovascular Outcomes in Older Adults: The Cardiovascular Health Study

Heart rate response to a timed walk and cardiovascular outcomes in older adults: the cardiovascular health study.

OBJECTIVES To determine the relationship between heart rate response during low-grade physical exertion (6-min walk) with mortality and adverse cardiovascular outcomes in the elderly. METHODS Participants in the Cardiovascular Health Study who completed a 6-min walk test were included. We used delta heart rate (difference between postwalk heart rate and resting heart rate) as a measure of chr...

The Relationships Between Daily Sleepiness and Cardiovascular Health Indicators in the Older Adults

Objectives: Cardiovascilar disesases and sleep disorders are two major health problems common in old age. The aim of the present study was to examine the relationship between daytime sleepiness and cardiovascular indices among Iranian older adults. Methods & Materials: A cross-sectional design was used. The sample included 321 older adults who were selected from primary healthcare centers in K...

Response to letter regarding article, "physical activity and heart rate variability in older adults: the cardiovascular health study".

BACKGROUND Cardiac mortality and electrophysiological dysfunction both increase with age. Heart rate variability (HRV) provides indices of autonomic function and electrophysiology that are associated with cardiac risk. How habitual physical activity among older adults prospectively relates to HRV, including nonlinear indices of erratic sinus patterns, is not established. We hypothesized that in...
