Abstract:
AIMS: Endothelial cell vascular endothelial growth factor receptor 2 (VEGFR-2) plays a pivotal role in angiogenesis, which induces physiological cardiomyocyte hypertrophy via paracrine signalling between endothelial cells and cardiomyocytes. We investigated whether a decrease in circulating soluble VEGFR-2 (sVEGFR-2) levels is associated with poor prognosis in patients with chronic heart failure (HF). METHODS AND RESULTS: We performed a multicentre prospective cohort study of 1024 consecutive patients with HF, who were admitted to hospitals due to acute decompensated HF and were stabilized after initial management. Serum levels of sVEGFR-2 were measured at discharge. Patients were followed up over 2 years. The outcomes were cardiovascular death, all-cause death, major adverse cardiovascular events (MACE) defined as a composite of cardiovascular death and HF hospitalization, and HF hospitalization. The mean age of the patients was 75.5 (standard deviation, 12.6) years, and 57% were male. Patients with lower sVEGFR-2 levels were older and more likely to be female, and had greater proportions of atrial fibrillation and anaemia, and lower proportions of diabetes, dyslipidaemia, and HF with reduced ejection fraction (<40%). During the follow-up, 113 cardiovascular deaths, 211 all-cause deaths, 350 MACE, and 309 HF hospitalizations occurred. After adjustment for potential clinical confounders and established biomarkers [N-terminal B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin I, and high-sensitivity C-reactive protein], a low sVEGFR-2 level below the 25th percentile was significantly associated with cardiovascular death [hazard ratio (HR), 1.79; 95% confidence interval (CI), 1.16-2.74] and all-cause death (HR, 1.43; 95% CI, 1.04-1.94), but not with MACE (HR, 1.11; 95% CI, 0.86-1.43) or HF hospitalization (HR, 1.03; 95% CI, 0.78-1.35). The stratified analyses revealed that a low sVEGFR-2 level below the 25th percentile was significantly associated with cardiovascular death (HR, 1.76; 95% CI, 1.07-2.85) and all-cause death (HR, 1.49; 95% CI, 1.03-2.15) in the high-NT-proBNP group (above the median), but not in the low-NT-proBNP group. Notably, the patients with high-NT-proBNP and low-sVEGFR-2 (below the 25th percentile) had a 2.96-fold higher risk (95% CI, 1.56-5.85) for cardiovascular death and a 2.40-fold higher risk (95% CI, 1.52-3.83) for all-cause death compared with those with low-NT-proBNP and high-sVEGFR-2. CONCLUSIONS: A low sVEGFR-2 value was independently associated with cardiovascular death and all-cause death in patients with chronic HF. These associations were pronounced in those with high NT-proBNP levels.
