Key result
Elevated heart rate was associated with an increased risk of all-cause mortality in elderly women (ROR 3.37; 95% CI 0.96-11.8), but did not predict mortality in elderly men.

Does elevated heart rate increase mortality risk in elderly individuals?
Odds Ratio: 3.37 (95% CI 0.96–11.8)
p-value: p=.0003
Perk et al. (2003) conducted a cohort in Elderly (n=422). Elevated heart rate vs. Lower heart rate was evaluated on All-cause mortality (ROR 3.37, 95% CI 0.96-11.8, p=.0003). Elevated heart rate was associated with an increased risk of all-cause mortality in elderly women (ROR 3.37; 95% CI 0.96-11.8), but did not predict mortality in elderly men.
