Abstract

Elevated resting heart rate (RHR) is associated with an increased cardiovascular disease (CVD) risk, but little is known about its association with cardiovascular health (CVH), assessed by the Life's Simple 7 (LS7) metrics. We explored whether ideal CVH was associated with RHR in a cohort free from clinical CVD. We conducted a cross-sectional analysis of baseline data (2000−2002) of 6457 Multi-Ethnic Study of Atherosclerosis participants in 2018. Each LS7 metric (smoking, physical activity, diet, body mass index, blood pressure, cholesterol and glucose) was scored 0–2. Total score ranged from 0 to 14. Scores of 0–8 indicate inadequate, 9–10 average, and 11–14 optimal CVH. RHR was categorized as <60, 60–69, 70–79 and ≥80 bpm. We used multinomial logistic regression to determine associations between CVH score and RHR, adjusting for age, sex, race/ethnicity, education, income, health insurance, and atrioventricular nodal blockers. Mean age of participants (standard deviation) was 62 (10) years; 53% were women; 47% had inadequate CVH, 33% average, and 20% optimal. Favorable CVH was associated with lower odds of having higher RHR. Compared to RHR <60 bpm, participants with optimal CVH had adjusted odds ratio (95% CI) of 0.55 (0.46–0.64) for RHR of 60-69 bpm, 0.34 (0.28–0.43) for 70–79 bpm, and 0.14 (0.09–0.22) for ≥80 bpm. A similar pattern was observed in the stratified analysis by sex, race/ethnicity and age. Favorable CVH was less likely to be associated with elevated RHR irrespective of sex, race/ethnicity and age. More research is needed to explore the usefulness of promoting ideal CVH to reduce elevated RHR, a known risk factor for CVD.
