Patients were classified into two groups, namely, SYNergy between PCI with TAXUS and Cardiac Surgery score >= 1 (n=45) and SYNergy between PCI with TAXUS and Cardiac Surgery score=0 (n=45). This is a cross-sectional, prospective study. RESULTS: Serum chromogranin A levels were significantly higher in the group with SYNergy between PCI with TAXUS and Cardiac Surgery score >= 1 compared to the group with SYNergy between PCI with TAXUS and Cardiac Surgery score=0 (1381.5 +/- 418.9 ng/mL and 1121.2 +/- 290.7 ng/mL, respectively; p=0.002). Serum chromogranin A levels were correlated with SYNergy between PCI with TAXUS and Cardiac Surgery score (r=0.556, p<0.04). ROC analysis showed that the area under the curve for serum chromogranin A levels was 0.687 (p=0.007), and the best cutoff value of 1,131 ng/mL had a sensitivity of 67% and a specificity of 65% for the prediction of coronary artery disease.CONCLUSION: Serum chromogranin A levels were increased in coronary artery disease patients with SYNergy between PCI with TAXUS and Cardiac Surgery score >= 1. Increasing serum chromogranin A levels are proportional to the SYNergy between PCI with TAXUS and Cardiac Surgery score.KEYWORDS: Chromogranin A. Coronary artery disease.
