Key result
A slow 2-minute heart rate recovery predicted all-cause mortality (RR 1.16; 95% CI 1.02-1.33; P=0.02), but lost predictive value after accounting for chronotropic response and exercise capacity.
Why the study?
Does a slow 2-minute heart rate recovery after cycle ergometer exercise predict all-cause mortality in healthy middle-aged men?
Cohort (n=1,102)
Yes
Does a slow 2-minute heart rate recovery after cycle ergometer exercise predict all-cause mortality in healthy middle-aged men?
Relative Risk: 1.16 (95% CI 1.02–1.33)
p-value: p=0.02
While a slow 2-minute heart rate recovery predicts all-cause mortality in healthy middle-aged men, it does not provide independent prognostic information beyond chronotropic response and exercise capacity.

Slow 2-minute heart rate recovery should not yet guide risk stratification in healthy men; challenges its independent value beyond chronotropic response and exercise capacity.
Savonen et al. (2011) conducted a cohort in Healthy (n=1,102). Slow heart rate recovery (HRR) was evaluated on All-cause mortality (RR 1.16, 95% CI 1.02-1.33, p=0.02). A slow 2-minute heart rate recovery predicted all-cause mortality (RR 1.16; 95% CI 1.02-1.33; P=0.02), but lost predictive value after accounting for chronotropic response and exercise capacity.
