Elevated resting heart rate in adolescent men and risk of heart failure and cardiomyopathy.

ABSTRACT:

Aims

This study aims to investigate the association of resting heart rate (RHR) measured in late adolescence with long-term risk of cause-specific heart failure (HF) and subtypes of cardiomyopathy (CM), with special attention to cardiorespiratory fitness.

Methods and results

We performed a nation-wide, register-based cohort study of all Swedish men enrolled for conscription in 1968-2005 (n = 1 008 363; mean age = 18.3 years). RHR and arterial blood pressure were measured together with anthropometrics as part of the enlistment protocol. HF and its concomitant diagnoses, as well as all CM diagnoses, were collected from the national inpatient, outpatient, and cause of death registries. Risk estimates were calculated by Cox-proportional hazards models while adjusting for potenti
