What is the relationship between resting heart rate and blood pressure?

Resting heart rate and blood pressure are partially independent cardiovascular risk factors that share some upstream drivers, both are elevated by chronic sympathetic dominance (from chronic stress, poor sleep, and low fitness) and both are reduced by aerobic training, but they can diverge: a man may have normal blood pressure with elevated resting heart rate (or vice versa), and the cardiovascular risk from elevated resting heart rate is additive to and independent of blood pressure risk (Palatini et al., Hypertension, 2006).

The shared driver of both elevated resting heart rate and elevated blood pressure in men 40–55 is often sympathetic nervous system overdrive from chronic stress, elevated cortisol, and poor sleep. The cardiovascular consequence of both operating simultaneously is substantially higher than either alone. The intervention that addresses both most efficiently: consistent moderate aerobic exercise (which lowers both through increased vagal tone and improved vascular compliance) and sleep restoration (which reduces nocturnal sympathetic activation).

Honesty Scale: Solid (1) for the additive and independent cardiovascular risk of elevated resting heart rate and blood pressure.

What to do: At each blood pressure measurement, also record your resting heart rate. If both are elevated, the combined risk is substantially higher than either alone, and both should be tracked as part of your cardiovascular risk management. Report both metrics to your physician at each appointment.
