Abstract:
BACKGROUND:Mast cell tryptase has recently been reported to be involved in atherosclerotic plaque destabilization. However, the results of these reports are conflicting. METHODS:The aim of this study was to characterize the role of tryptase as a prognostic marker of patient cardiovascular complexity in acute coronary syndrome (ACS). Furthermore, its association with an angiographic scoring system [defined by the SYNergy between percutaneous coronary intervention (PCI) with the TAXUS drug-eluting stent and the cardiac surgery (SYNTAX) score] was examined. The serum tryptase was measured at admission in 65 consecutive ACS patients and in 35 healthy controls. In the patients with ACS, a composite measure of clinical and angiographic patient cardiovascular complexity was indicated by two of the following: clinical adverse events at hospitalization, at least 2 epicardial coronary arteries involved in the atherosclerotic disease, more than 1 stent implanted or more than 2 coronary artery disease risk factors. RESULTS:The tryptase measurements were lower in patients without the composite measure (p < 0.0005). Linear regression showed a significant relationship between tryptase levels and the SYNTAX score (SX-score). Conversely, high-sensitivity troponin values did not correlate with either the composite outcome or the SX-score. The predictive accuracy of serum tryptase for the composite outcome was set at the cut-off point of 5.22 ng/ml (sensitivity 81% and specificity 95.7%). CONCLUSION:In ACS patients, serum tryptase levels at admission may predict patient cardiovascular complexity more reliably than currently known biomarkers. Further studies are needed to demonstrate the long-term prognostic role of this biomarker in ACS.
