Abstract:
Objective The 47 myocardial infarction patients (male 41, female 6, average ages 55 7?9 7 years) with silent myocardial ischemia (type Ⅱ SMI) were chosen The relationship was studied between the history of myocardial infarction (MI)and the degree of coronary arterial stenosis and the residual degree of stenosis after percataneous transluminal coronary angioplasty (PTCA) Methods All patients with MI were performed with exercise testing electrocardiogram to investigate the degree of myocardial ischemia The patients were also studied the degree of coronary arterial stenosis before and after PTCA Results The results showed before PTCA, the degree of the patients′ coronary arterial stenosis with a period of no more than three months of MI was higher than that of those patients′ with a period of over three months( P
