Soluble Vascular Adhesion Protein-1 Predicts Incident Major Adverse Cardiovascular Events and Improves Reclassification in a Finnish Prospective Cohort Study

Abstract
Background—: Vascular adhesion protein-1 (VAP-1) associates to subclinical atherosclerotic manifestations in young people, but its association to incident major adverse cardiovascular events (MACEs) and cardiovascular mortality in a general population is not known. Methods and Results—: We used a newly developed ELISA to measure soluble VAP-1 (sVAP-1) levels in 2775 participants (mean age, 60 years) from a prospective cohort study (the FINRISK 2002). During a mean follow-up of 9 years, 265 participants underwent a MACE, and these participants had higher levels of sVAP-1 than those without MACE (868 ng/mL and 824 ng/mL, respectively, P 50 years without prior MACE, and inclusion of sVAP-1 in the risk prediction model improved the clinical net reclassification improvement of incident MACE. Thus, sVAP-1 may be a potential new biomarker for cardiovascular diseases.
