TI  - Early Differentiation of Stress Cardiomyopathy from Acute Anterior Wall 
      Myocardial Using Changing Cardiac Enzyme Patterns.

AB  - BACKGROUND: Most patients with acute anterior wall ST elevation myocardial 
      infarction (STEMI) or stress cardiomyopathy (SCMP) show elevations in cardiac 
      enzymes that peak within 24 hours. The changing pattern of cardiac enzymes can be 
      an early clue to the differentiation of anterior STEMI and SCMP. METHODS: This 
      study was a retrospective analysis (matching cases and respective control 
      subjects) performed at a single center. We compared 27 patients with SCMP and 30 
      patients with anterior STEMI. We used laboratory data included cardiac marker, 
      such as the initial creatine kinase MB (CK-MB) fraction and troponin T (Tn-T), at 
      admission and peak CK-MB and Tn-T at follow up. RESULTS: The mean age was 69.3 +/- 
      14.1 years, and 38.6% of patients were female. The SCMP patients were older, more 
      often female, and had lower left ventricular ejection fractions than the anterior 
      STEMI patients. The initial CK-MB was higher in the anterior STEMI group than in 
      the SCMP group. In contrast, the initial Tn-T level was not significantly 
      different between the 2 groups. Peak CK-MB and Tn-T levels and change from 
      initial levels were significantly greater in the anterior STEMI group than they 
      were in the SCMP group. SCMP could be differentiated from anterior STEMI based on 
      peak CK-MB > 46.65 ng/mL or Tn-T > 1.56 ng/mL. CONCLUSIONS: Follow-up changes in 
      cardiac enzymes can be an effective early tool for differentiating SCMP from 
      anterior STEMI.
