Based on the latest achievements of the mechanism of peradaptation to myocardium ischemia and pharmacodic preadaptation up to date, observations were made on 80 patients of acute myocardial infarction to assess the enzymatic dynamics of myocardium, symptoms after myocardial infarction occurred like cardiac rhythm abnormality, anginapectoris, heart failure, cardiogenic shock, reinfarct and the mortality in the hospital. The results indicated that peradaptation to myocardium ischemia is of significance in protecting myocardium, reducing the areas of infarction, abating the cardiac insufficiency after infarction and reducing the abnormality of heart rhythm and significantly ameliorating the prognosis.
