Background: White blood cell (WBC) count is associated with incident coronary heart disease (CHD). Coronary artery calcification (CAC) is a measure of subclinical atherosclerosis that predicts CHD events. Since data are sparse regarding the association of WBC count with future CAC, we examined the association of WBC count in early adulthood (age 18-30 yrs.) with the presence of CAC 15 or 20 years later (age 33-50 yrs.). Methods: We included CARDIA participants who had baseline data on risk factors and WBC counts, and participated in the Year (Y) 15 or Y20 examinations with CAC score information. We performed age-, sex-, and race-adjusted linear regression analyses to examine the cross-sectional association between baseline (Y0) WBC count (total and subtypes) and known CHD risk factors, including systolic blood pressure (SBP), BMI, smoking (packs/year), total and HDL-cholesterol. We used multiple logistic regressions to assess prospective associations between Y0 WBC count and the presence of CAC at Y15 and Y20. Results: Among 3094 participants, mean (SD) age at baseline was 25± 4 years, 57% were women and 45% were black. In total, 263 and 566 subjects had CAC score>0 at Y15 and Y20 examination, respectively. Y0 SBP, BMI, and smoking (p<0.001), and HDL-cholesterol (p=0.01) were significantly associated with Y0 total WBC counts. Compared to participants without CAC at Y20, those with CAC score>0 had higher Y0 counts (10 9 /L, SD) of total WBC (6.0 ± 1.8 vs. 6.2 ± 1.9, p=0.04), lymphocyte (2.16 ± 0.75 vs. 2.23 ± 0.76 p=0.05), and eosinophil (0.16 ± 0.13 vs. 0.18 ± 0.16, p<0.001). These counts were positively associated with the presence of Y20 CAC after adjusting for potential confounders ( Table 1 ). Similar patterns were observed for Y15 CAC (data not shown). Conclusion: Total WBC and certain subtype counts in young adulthood are significantly associated with presence of CAC 15 or 20 years later in early middle age. These findings suggest the possible involvement of WBC in the initiation and/or early development of atherosclerosis. Table 1.

Methylome Analysis

Background: Trajectory of AHA’s cardiovascular health (CVH) through young adulthood are associated with subclinical CVD. The human epigenome is modifiable by lifestyle and environmental factors and may be an important mechanism of CVH outcomes. We sought to determine associations of epigenetic markers with CVH trajectories and with coronary artery calcification (CAC) through young adulthood. Methods: Among CARDIA ppts, we performed methylome analysis at follow up year (Y) 15 and Y20 using Illumina Methylation EPIC array (~850K CpG loci). We compared methylome between those with optimal CVH at baseline and remained stable (optimal-stable, n=645) and individuals with baseline optimal but declining CVH during follow up (n=100) to identify methylomic biomarkers of CVH trajectories. Differentially methylated CpGs were further examined in association with incident CAC risk at Y25 (n=745), and for their potential mediating role in CVH-associated CAC risk. Results: In 1,087 CARDIA ppts (mean age=25 at baseline), we identified 25 hypermethylated CpGs (18 at Y15, 13 at Y20, including 6 seen at both Y15 and Y20) significantly associated with optimal-stable CVH trajectories. The 6 common CpGs were stable (mean ICC = 0.66) whereas the remaining 19 CpGs were dynamic (mean ICC = 0.39) over a 5-year interval. Hypermethylation of 6 stable CpGs was associated with a decreased risk of having future CAC incidence ( Table 1 ). Hypermethylation of 10 (out of 19) dynamic CpGs at Y20 was associated with a decreased risk for incident CAC while the associations was less pronounced at Y15. Mediation analyses showed that hypermethylation of these 16 CpGs at Y15 and Y20 contributed 15% and 23% reduction in the CVH-associated relative risks (RRs) of CAC incidence at Y25. Conclusion: We observed distinct methylomic patterns in young adulthood with stable optimal CVH trajectories relative to those with declining CVH. CVH associated methylomic marks may predict CAC incidence and potentially mediate the associations of CVH trajectories with incident CAC risk.
