Relation of Heart Rate With Cardiovascular Disease in Normal-Weight Individuals: The Chicago Heart Association Detection Project in Industry

The authors investigated the association of resting heart rate (RHR) with cardiovascular disease (CVD) risk factors and mortality among normal‐weight individuals. Using data from our cohort (baseline examination in 1967–1973), individuals with a body mass index of 18.5 to 24.9 kg/m 2 (men [n=3724] and women [n=4929] aged 18–39; men [n=1959] and women [n=3735] aged 40–59), were grouped by RHR: <75, 75–84, and ≥85 beats per minute (bpm).
