Abstract:
Objective To approach the significance of serum protein fingerprinting on the identification of different courses of acute myocardial infarction. Methods For 153 patients of acute myocardial infarction, including 45 cases of just admitted patients, 12 cases of 3h admitted patients, 22 cases of 6h admitted patients, 24 cases of 9h admitted patients, 24 cases of 12h admitted patients, 16 cases of 24h admitted patients and 10 cases of 48h admitted patients. The relative contents of serum proteins were detected by IMAC3 chip and proteinchip reader (CipherGen Inc., VS). Results On the M/Z values ranged from 4KDa to 12KDa, ten protein contents were obviously different between the different courses of acute myocardial infarction. All the patients in different courses were diagnosed correctly, the accuracy was 100%(153/153). Both sensitivity and specificity were also 100% in learning mode. Conclusion Different courses of acute myocardial infarction patients can be quickly and correctly diagnosed by this method with high sensitivity and specificity. That will be widely used in clinical application
