ObjectivesThis study sought to evaluate the predictive value of baseline placental growth factor (PlGF) for long-term cardiovascular events in acute coronary syndromes (ACS).BackgroundA biomarker of vascular inflammation, PlGF is identified as a powerful predictor for short-term outcome in patients with ACS.MethodsIn 544 patients who were enrolled in the placebo arm of the c7E3 Fab Anti Platelet Therapy in Unstable REfractory angina (CAPTURE) trial, PlGF levels were determined as well as markers of myocardial necrosis (troponin T [TnT]), general inflammation (high-sensitivity C-reactive protein [hsCRP]), and platelet activation (soluble CD40 ligand [sCD40L]). Cox proportional hazard regression analyses were applied to evaluate the relationship between biomarkers and the occurrence of all-cause death or non-fatal myocardial infarction during a median follow-up period of four years.ResultsPatients with PlGF levels in the fourth and fifth quintile (>27 ng/l) had higher mortality than those with lower levels (10.8% vs. 3.2%; hazard ratio [HR], 3.3; 95% confidence interval [CI], 1.6 to 7.1), as well as a higher incidence of the composite end point of death or myocardial infarction (27.6% vs. 11.3% events; HR, 2.6; 95% CI, 1.7 to 3.9). The relationship between PlGF and the composite end point remained significant after adjustment for TnT, sCD40L, and hsCRP (adjusted HR, 3.3; 95% CI, 2.0 to 5.4).ConclusionsIn patients with ACS, elevated plasma levels of PlGF are associated with adverse cardiac outcomes during long-term follow-up. These data suggest that PlGF as a more specific marker of vascular inflammation should be considered for risk stratification of patients with ACS rather than general markers of inflammation.
