Association between heart rate and mortality in elderly Chinese

Objective To assess the associations between heart rate(HR)with all-cause,cardiovascular and non-cardiovascular mortality in elderly Chinese aged≥60 years old.Methods Data from present study were derived from the prospective urban and rural epidemiology study in China(PURE-China).HR was measured at the baseline by trained health workers using digital sphygmomanometers.Cardiovascular mortality,non-cardiovascular mortality,and all-cause mortality events were collected through standardized case reports at follow-ups.Cox frailty model was used to explore the correlation between heart rate and risk of death.Results A total of 8487 subjects aged≥60 years old were included in this study(3925 males,46.25%,heart rate:[73.2±11.6]beats/min[bpm];4562 women,53.75%,heart rate:[75.8±10.9]bpm).
