The relation between silent ischemia and coronary artery disease severity in diabetics

PurposeThe aim of this work was to examine the relation between the severity of silent ischemic episodes detected by ambulatory ECG recording and the angiographic severity of coronary artery disease (CAD).MethodsFifty patients with chronic stable angina pectoris and type 2 diabetes mellitus were enrolled in the study.Among the study group, there were 33 males and 17 females; and their mean age was 61±6.5years.
