Abstract
In recent years, Pregnancy-associated Plasma Protein-A (PAPP-A), a metalloproteinase originally identified in the plasma of pregnant women and then found in both men and women, has been studied for its potential involvement in cardiovascular disease. Several studies have indicated that PAPP-A might be considered as a marker of Acute Coronary Syndromes (ACS) able to predict outcome of patients with this clinical presentation. We have recently demonstrated that PAPP-A is able to induce TF expression in endothelial cells in vitro, suggesting an active involvement of this metalloproteinase in thrombotic events. We found that transcoronary PAPP-A levels were significantly higher in ACS-NSTEMI patients as compared to patients with SCAD and that elevated PAPP-A concentrations were associated with higher rate of TF consumption. results of this study permit for the first time to speculate that this metalloproteinase, does not represent only an independent risk factor for adverse cardiovascular or a marker of disease to obtain and early diagnosis of ACS, but it rather might play an “active” role in the pathophysiology of ACS as an effector molecule able to induce thrombus formation in the coronary circulation.File | Dimensione | Formato | |
