Abstract

To diagnose acute myocardial infarction (MI), many cardiac markers have been used in hematologic and biochemical analysis, and many studies have been published for hematologic and biochemical analysis associated with human acute MI. However, after occurrence of acute MI, the serial investigation for values in hematologic and biochemical analysis including chronic MI has rarely been performed. To observe the change of the serial values in hematologic and biochemical analysis, we induced artificial MI. The left main descending artery (LMDA) of the left coronary artery was ligated during the progression (day 1, 3, 5, 7, 14 and 30) of MI. Total 66 Sprague-Dawley rats were divided into the sham group (n=24, thoracotomy without LMDA ligation) and the experimental (MI) group (n=42, with LMDA ligation). And all individual in each group was sacrified at day 1, 3, 5, 7, 14 and 30 for the hematologic and biochemical analysis. In comparison of hematologic analysis between the sham and MI groups, the mean values of red blood cell (RBCs), hemoglobin and hematocrit (HCT) showed a steady increase. In biochemical analysis, the mean values of glucose, cholesterol, total creatine kinase (CK) and isoenzyme MB, and lactate dehydrogenase (LDH) were increased in all MI groups compared with the sham groups. The results of this study suggest that early hematologic and biochemical mean values occurred after acute MI are similar to those of human acute MI. In conclusion, we could observe the alterations and serial values in hematologic and biochemical analysis to the extent of chronic status after acute MI.
