Methods: Ninety-eight patients with myocardial infarction admitted to our hospital were enrolled. All patients were randomly divided into routine group and grade-5 method group, with 49 patients in each group. The blood lipid index, body mass index (BMI), six-minute walking distance (6MWD) and smoking rate of two groups between before and after the intervention method were compared. And DTI was used to evaluate the cardiac function changes of patients with myocardial infarction during rehabilitation period before and after underwent the grade-5 method intervention of early activity. And the qualities of life of patients with myocardial infarction between before and after different intervention method were compared. Results: Compared with blood liquid indexes pre intervention, the total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C) and BMI post intervention were significantly reduced, while high density lipoprotein cholesterol (HDL-C) and 6WMD pot intervention were significantly enhanced (t routine group =3.01, t=5.57, t=3.65, t=4.69, t=2.39, t=8.94, t grade-5 method group =4.22, t=5.53, t=4.86, t=9.96, t=7.31, t=14.94, P<0.05). And the difference of these indexes post intervention between two groups were significant (t=6.257, t=8.114, t=9.587, t=10.257, t=15.387, t=11.223, P<0.05). Compared with the indexes pre intervention, the left ventricular ejection fraction (LVEF) post intervention was increased, the E peak post intervention was increased, the A peak post intervention was decreased, and the E/A post intervention was increased both the routine group and the grade-5 method group, and the differences of them between pre and post intervention were significant (t=5.11, t=4.74, t=2.04, t=4.99, t=8.71, t=8.46, t=4.10, t=10.39, P<0.05). After the intervention, the differences of various indexes between two groups were significant (t=4.56, t=5.41, t=6.57, t=8.41, P<0.05). Compared with those pre intervention, the scores of physiological function, physiological accountability, body pain, vitality, social function, emotional role and mental health of routine group and grade-5 method group were significantly increased (t routine group =3.78, t=5.21, t=2.98, t=7.24, t=6.50, t=7.36, t=4.55, t grade-5 method group =5.68, t=8.14, t=5.87, t=10.55, t=11.25, t=8.68, t=9.24, P<0.05). After the intervention, the differences of various indexes between two groups were significant (t=3.46, t=4.56, t=8.35, t=6.54, t=9.32, t=5.56, t=7.64, P<0.05). Conclusion: The rehabilitation of cardiac function of patients with myocardial infarction who adopts grade-5 method of early activity is better, and it can promote and improve quality of life.
