Abstract

Purpose The purpose of this study was to estimate the heart rate variability (HRV)–related lifetime cardiovascular disease (CVD) risk. Methods We followed 9744 participants without baseline CVD and used a life-table approach to estimate lifetime CVD risk (coronary heart disease, heart failure, and stroke) from 45 through 85 years according to several HRV measures (the SD of RR intervals [SDNN], the root mean square of successive differences of successive RR intervals, the mean of all normal RR intervals [meanNN], low-frequency [LF] and high-frequency [HF] power, and the LF/HF ratio). Results During 192,110 person-years of follow-up, we documented 2856 CVD events. Cox regression analyses with the false discovery rate method correction showed independent associations of SDNN, meanNN, LF, and LF/HF in women with CVD. Lifetime CVD risks in the lowest compared with the highest tertile were significantly increased in men for LF/HF (51.3% [95% confidence interval, 47.3–54.7] vs. 43.9% [40.1–47.2]), and in women for SDNN (39.4% [36.0–43.0] vs. 29.9% [26.3–33.0]), meanNN (39.3% [35.7–42.7] vs. 28.9% [25.7–31.7]), LF (39.4% [35.9–43.0] vs. 30.0% [26.2–33.2]), and LF/HF (37.6% [33.9–40.9] vs. 30.0% [26.8–32.7]). Conclusions Greater HRV was modestly associated with lower lifetime CVD risk.
