[Relationship between serum C-reactive protein and creatine kinase isoenzyme in acute myocardial infarction].

OBJECTIVE: To investigate the relationship between serum c-reactive protein(CRP) and creatine kinase isoenzyme (CK-MB) in the diagnosis of acute myocardial infarction (AMI). METHODS: We assessed the serum CK-MB and CRP concentration in 52 patients with definite AMI at different time after their infarction. RESULTS: 12 hours after infarction there were 100% and 44.2% patients with positive results in CK-MB and CRP respectively, and 48 hours are 57.7% and 86.5%. By continuous observation we found that the peaks of CK-MB and CRP occurred respectively at 12 hours and 48 hours after infarction. CONCLUSION: It is suggested that as a diagnostic marker CRP is superior to CK-MB in sabacent myocardial infarction patients.
