High male resting heart rate marker for increased mortality

The Danish prospective cohort study in 2800 healthy middle-aged men followed for 16 years showed that mortality increased by 16% for every 10 beats per minute (bpm) increase in resting heart rate.

Compared with men who had a resting heart rate less than or equal to 50 bpm, those with resting heart rates in the range 51 to 80 bpm had a 40% increased mortality risk, those in the range 81 to 90 bpm had a two-fold increased risk, and those with heart rate over 90 bpm had a three-fold risk.

The mortality rates were adjusted for physical fitness measured by bicycle ergometer, leisure time physical activity, smoking, alcohol
