Rumour: Resting heart rate is predictive of cardiovascular disease (CVD) related mortalities only.
Truth: This is false.
Resting heart rate can be used to predict both CVD-related mortalities, as well as all-cause mortalities, where the primary cause of death is not related to cardiovascular disease. It has been suggested that an elevated resting heart rate is a result of an autonomic tone imbalance which can trouble different systems of the body, including ones responsible for inflammation, metabolism, and neurologic processes.
