Objectives Growing evidence has indicated the potential clinical usefulness of measuring different forms of cytokeratin 18 in patient sera (M30 antigen for apoptosis and M65 antigen for necrosis) for distinguishing different forms of cell death. Preliminary data have reported altered levels of cytokeratin 18 fragments in patients with acute coronary syndrome (ACS) and ischemic heart disease. In this study, serum levels of M30 and M65 were measured in 74 patients with ACS [including 17 cases with unstable angina and 57 patients with acute myocardial infarction (AMI)], 25 patients with stable angina, and 23 controls. Methods In patients with ACS, serial measurements of M30 and M65 were obtained, and for each patient, the following values were determined: (i) values at admission, (ii) values obtained 24 h after symptom onset, and (iii) values obtained at 48 h after symptom onset. The severity of coronary atherosclerosis was expressed using the Gensini score. Results On admission, M30 and M65 levels in ACS patients were similar to those observed in stable angina patients and control participants. In AMI patients, serum levels of M30 peaked at 24 h and declined thereafter at 48 h. Notably, serum levels of M30 measured at 24 h correlated significantly and positively with the extent of coronary artery disease as measured by the Gensini score in AMI patients (r = 0.253, P < 0.05). Conclusion Serum levels of the apoptotic marker M30 peak at 24 h after AMI and reflects the extent of coronary artery disease in this patient group.
