Circulating Vascular Cell Adhesion Molecule-1 and Incident Heart Failure: The Multi-Ethnic Study of Atherosclerosis (MESA).

Background Serum levels of vascular cell adhesion molecule-1 (VCAM-1) are reflective of endothelial activation. Although VCAM-1 has been implicated in the pathogenesis of heart failure with preserved ejection fraction (HFpEF), the prospective association of VCAM-1 with development of clinically overt heart failure (HF) across ejection fraction categories is unclear. Methods and Results In MESA (the Multi-Ethnic Study of Atherosclerosis), we evaluated the association of VCAM-1 at examination 2 (2002-2004) with incident HF (HFpEF and HF with reduced ejection fraction) after adjustment for cardiovascular risk factors. Incident HF was independently adjudicated as first hospitalization for symptomatic HF. Among 2297 participants (mean age, 63 years; women, 53%), those with higher VCAM-1 were more likely to be White race, had higher blood pressure, and had lower kidney function. Over a median of 14.4 years, there were 102 HF events (HFpEF=65; HF with reduced ejection fraction=37). After covariate adjustment, each doubling of VCAM-1 was associated with incident HF (hazard ratio [HR], 1.94; 95% CI, 1.17-3.23;
