Heart rate response and recovery during exercise and dementia risk: a prospective UK biobank study.

ABSTRACT: The heart rate response/recovery (HRR) index, a common indicator for cardiovascular health during exercise, has been linked with neurocognitive disorders and mortality. However, the relationship between HRR index and dementia remains unknown. Electrocardiogram data from 46,348 middle-aged and older adults from the UK Biobank were analyzed following a standardized submaximal exercise stress test (15-second baseline, 6-minute exercise, and 1-minute recovery). The HRR index was calculated as the product of heart rate responses ratio during exercise (peak/resting heart rate) and recovery ratio (peak/recovery heart rate). We found that 519 participants were ascertained with dementia, including 232 with Alzheimer's disease (AD) and 85 with vascular dementia (VaD) during a median follow-up period
