Abstract 13044: Serum Vascular Endothelial Growth Factor-C Levels are Inversely Associated with the Risk of Cardiac and Cerebrovascular Events Following Drug-eluting Stent Implantation
Background: Vascular endothelial growth factor-C (VEGF-C) plays a key role in lymphangiogenesis. Recently, we demonstrated that VEGF-C is closely associated with dyslipidemia and atherosclerosis. However, the prognostic value of VEGF-C levels after drug-eluting stent (DES) implantation is unknown.
Methods and Results: We performed a prospective cohort study involving a total of 443 patients (age, 71.7±9.0 y [SD]; male, 73.8%; number of lesions, 1.6±0.8) who underwent successful DES implantation. Patients were recruited between January 2010 and October 2013, and were followed up over 3 years. The primary outcome was major adverse cardiac and cerebrovascular events (MACCE) defined as cardiovascular death, hospitalization due to acute coronary syndrome, stroke, heart failure, and coronary revascularization. The median follow-up was 617 (inter-quartile range, 320-937) days. Pre-procedural serum levels of high-sensitivity C-reactive protein (hsCRP), vascular endothelial growth factor-A (VEGF-A), and VEGF-C were measured. During the follow-up period, MACCE developed in a total of 106 patients (23.9%). Patients were divided into two groups based on the median of each biomarker. In Kaplan-Meier analyses, low-VEGF-C (P=0.0005 by log-rank test), but not high-hsCRP (P=0.3) or high-VEGF-A (P=0.3), was significantly associated with the risk of MACCE. Multivariate Cox proportional hazard analyses revealed that levels of VEGF-C (hazard ratio [HR], 0.77 per 1-SD increase; 95% confidence interval [CI], 0.62-0.94; P=0.011), but not hsCRP (HR, 1.05; 95% CI, 0.86-1.25; P=0.6) or VEGF-A (HR, 1.04; 95% CI, 0.86-1.23; P=0.6), were inversely and significantly associated with MACCE after adjustment for age, gender, and established risk factors, the number of lesions, and type of DES. Finally, we performed stepwise multivariate Cox proportional hazard analysis including data on age, gender, established risk factors, the number of lesions, type of DES, and VEGF-C levels. Notably, the only independent predictor of MACCE was the VEGF-C level (HR, 0.74 per 1-SD increase; 95% CI, 0.61-0.91; P=0.0042), followed by diabetes (HR, 1.47; 95% CI, 0.98-2.21; P=0.060).
Conclusions: A low VEGF-C value may serve as a predictor of MACCE after DES implantation.
