Abstract
IN recent years, diffuse myocardial fibrosis has received much attention by its difficulty in making diagnosis and its diverse etiology although the causal relationship between myocardial fibrosis and disease of the coronary arteries has been well recognized in many cases. The anatomic changes in the coronary arteries, however, seemed not always to be proportional to the changes in the myocardium. Though the importance of the sclerosis in proximal coronary arteries has been recognized, yet, changes in the small arteries in the myocardium and their effect on the myocardial nutrition have received very little attention.
