Abstract 381: Ideal Cardiovascular Health and Cardiovascular Disease: Heterogeneity Across Event Phenotype and Contribution of Multiple Biomarkers
Aims: To investigate whether or not the association between baseline cardiovascular health (CVH) and incident cardiovascular disease (CVD) differs by event phenotypes and to address the mediating effect of inflammatory and haemostatic blood biomarkers. Methods: The association of ideal CVH with outcomes was computed in 9312 middle-aged men from Northern Ireland and France (whole cohort) in multivariable Cox proportional hazards regression analysis. The mediating effect of baseline blood biomarkers was evaluated in a case control study nested within the cohort after 10 years of follow-up. Results: After a median follow-up of 10 years, 614 first CHD events and 117 first stroke events were adjudicated. Compared to those with poor CVH, those with an ideal CVH profile at baseline had a 72% lower risk of CHD (HR=0.28; 95% CI: 0.17; 0.46) and a 76% lower risk of stroke (HR=0.24; 95% CI: 0.06; 0.98). No heterogeneity was detected across main CHD and main stroke phenotypes. While significantly lower mean concentrations of hs-CRP, IL-6 (inflammatory markers), and fibrinogen, von Willbrandt factor (haemostatic factors) were noted in the controls with higher CVH status, the association of CVH with incident CHD was not attenuated upon adjustment for these biomarkers. Conclusion: these results support the universal promotion of ideal CVH for CVD in general and suggest that the lower risk of CHD associated with ideal CVH is independent from inflammatory and haemostatic biomarkers.
