Abstract
We examined the temporal longitudinal associations of carotid-femoral pulse wave velocity (cfPWV) and carotid intima-media thickness (cIMT) with the risk of elevated resting heart rate (RHR) and high-sensitivity C-reactive protein (hsCRP). We studied 3,862 adolescents, mean age 17.7 (SD 0.3 yr), followed-up for 7 yr until age 24.5 (0.7) yr, from the Avon Longitudinal Study of Parents and Children, UK. RHR, fasting plasma hsCRP, cfPWV, and cIMT were repeatedly assessed and analyzed using logistic regression, linear mixed-effect, and structural equation models adjusting for important covariates. Among 3,862 adolescents [2,143 (55.5%) female], 10% and 44% were at moderate-to-high risk of elevated RHR and hsCRP at 24.5 yr, respectively. Higher cfPWV at 17.7 yr was associated with elevated RHR risk at follow-up [odds-ratio (OR) 1.58 (CI 1.20-2.08); P = 0.001], whereas cIMT at 17.7 yr was associated with elevated hsCRP risk [OR 2.30 (1.18-4.46); P = 0.014] at follow-up, only among females. In mixed model, 7-yr progression in cfPWV was directly associated with 7-yr increase in RHR [effect-estimate 6 beats/min (1-11); P = 0.017] and hsCRP. cIMT progression was associated with 7-yr increase in RHR and hsCRP. In cross-lagged model, higher cfPWV at 17.7 yr was associated with higher RHR (β = 0.06, standard error = 3.85, P < 0.0001) at 24.5 yr but RHR at 17.7 yr was unassociated with cfPWV at 24.5 yr. Baseline cIMT or RHR was unassociated with either outcome at follow-up. Higher hsCRP at 17.7 yr was associated with higher cfPWV and cIMT at 24.5 yr. In conclusion, adolescent arterial stiffness but not cIMT appears to precede higher RHR in young adulthood, whereas elevated hsCRP in adolescence preceded higher cfPWV and cIMT.NEW & NOTEWORTHY Higher arterial stiffness but not carotid-intima media thickness in adolescence preceded higher resting heart rate in young adulthood, however, elevated high sensitivity C-reactive protein in adolescence preceded higher arterial stiffness and carotid intima-thickness in young adulthood in the temporal causal path. Low-grade inflammation during adolescence may be causally associated with the development of subclinical arteriosclerosis and atherosclerosis in young adulthood.

Abstract
Abstract
Background
Arterial stiffness, a precursor of arteriosclerosis, measured using carotid-femoral pulse wave velocity (cfPWV) is a strong predictor of cardiovascular morbidity and mortality in adults. Emerging evidence among adolescents, young adults, and middle-aged adults suggest that arterial stiffness may predict the risk of hypertension, obesity, insulin resistance, and the onset of type 2 diabetes and could be a causal risk factor for these diseases. However, it is unknown whether higher arterial stiffness temporally precedes elevated inflammation in the young population or if there is a bi-directional relationship. This evidence is crucial to developing interventions for attenuating arterial stiffness in early life.
Purpose
To examine the temporal causal longitudinal associations between repeated measures of cfPWV and high sensitivity C-reactive protein (hsCRP).
Methods
We studied 3862 adolescents, aged 17.7 years, followed-up for 7 years, from Avon Longitudinal Study of Parents and Children, birth cohort, UK. Fasting plasma hsCRP was assessed at 17.7 and 24.5-year clinic visits. In the same clinic visits, cfPWV was computed from pressure waveforms obtained using the Vicorder device (Skidmore Medical, Bristol, UK), 5 minutes after participants rested in a semi-prone position, with 2 blood pressure measurement channels and 2 Velcro pressure sensor cuffs applied over each of the carotid and femoral arteries. The assessment was repeated until three readings that were within 0.5 m/s of each other were recorded. We conducted autoregressive cross-lagged structural equation model path analyses to untangle temporal associations. We adjusted for sex, time in years between ages 17.7 and 24.5 years, age, low-density lipoprotein cholesterol, insulin, triglyceride, high-density lipoprotein cholesterol, fasting blood glucose, systolic blood pressure, heart rate, dual-energy Xray absorptiometry measured total fat mass and lean mass, ActiGraph measured moderate to vigorous physical activity at 15.5 years, smoking status, and family history of cardiovascular and metabolic diseases.
Results
Among 3862 adolescents (55.5% female), median (IQR) hsCRP at 17.7 and 24.5 years were 0.56 (0.98) mg/L and 0.84 (1.62) mg/L, respectively. The median (IQR) cfPWV at 17.7 and 24.5 years were 5.79 (0.66) m/s and 6.12 (1.12) m/s, respectively. Higher hsCRP at age 17.7 years was associated with higher cfPWV [Standardized β = 0.058, standard error = 0.004, p=0.037] at age 24.5 years. However, higher cfPWV at age 17.7 years was not associated with higher hsCRP [β = 0.023, standard error = 0.243, p=0.341] at 24.5 years.
Conclusion
We observed that elevated low-grade inflammation in adolescence may temporally cause higher arterial stiffness 7 years later, but not vice versa. Clinical and public health interventions targeted at reducing low-grade inflammation to regress the development of arteriosclerotic cardiovascular disease before mid-adulthood are needed.

Abstract
Abstract
Background
The causal role of high-sensitivity C-reactive protein (hsCRP) in the evolution of preclinical cardiovascular disease remains unclear. A previous longitudinal study concluded that hsCRP measured in childhood was not associated with a single measure of carotid intima-media thickness (cIMT) assessed at mid-adulthood. The use of hsCRP samples stored for 25 years prior to analysis might have confounded this previous findings. In the young population of adolescents and young adults no study has investigated whether elevated hsCRP temporally precedes higher cIMT or if bi-directional associations exist, due to the lack of repeated measures of cIMT.
Purpose
To examine the temporal causal longitudinal associations between repeated measures of cIMT and hsCRP in a young population.
Methods
We studied 3862 adolescents, aged 17.7 years, followed-up for 7 years, from Avon Longitudinal Study of Parents and Children, birth cohort, UK. Fasting plasma hsCRP was assessed at age 17.7 and 24.5-year clinic visits. cIMT from the right and left common carotid arteries at 17 years was assessed by ultrasound using a linear 12-MHz transducer (Vivid7, GE Medical, Chicago, Illinois) and cIMT from the right and left common carotid arteries at 24 years was measured using an ultrasound machine (CardioHealth Panasonic and a 13.5 MHz linear array broadband transducer (probe; centre frequency 9.0 MHz). We conducted autoregressive cross-lagged structural equation model path analyses to untangle temporal and bi-directional associations. We adjusted for sex, time in years between ages 17.7 and 24.5 years, age, low-density lipoprotein cholesterol, insulin, triglyceride, high-density lipoprotein cholesterol, fasting plasma glucose, systolic blood pressure, heart rate, dual-energy Xray absorptiometry measured total fat mass and lean mass, ActiGraph measured moderate to vigorous physical activity at 15.5 years, smoking status, and family history of cardiovascular and metabolic diseases.
Results
Among 3862 adolescents (55.5% female), median (IQR) hsCRP values at 17.7 and 24.5 years were 0.56 (0.98) mg/L and 0.84 (1.62) mg/L, respectively. The median (IQR) cIMT values at 17.7 and 24.5 years were 0.48 (0.05) mm and 0.54 (0.09) mm, respectively. Higher hsCRP at age 17.7 years was associated with cIMT [Standardized β = 0.062, standard error = 0.004, p=0.035] at age 24.5 years. However, higher cIMT at age 17.7 years was not associated with higher hsCRP [β = −0.014, standard error = 0.284, p=0.523] at 24.5 years.
Conclusion
These findings in the largest adolescent population to date suggest that higher inflammation in adolescence temporally precede higher carotid thickness 7 years later and there was no bi-directional relationship. Clinical and public health interventions targeted at reducing low-grade inflammation to potentially attenuate the development of atherosclerotic cardiovascular disease in the young population are warranted.
