title: Silent myocardial ischaemia and cardiac autonomic neuropathy in diabetics.
abstract: Treadmill exercise electrocardiography was performed in 47 patients of diabetes to detect latent coronary artery disease. Eighteen patients (36.3%) were found positive on treadmill test. All forty seven subjects were evaluated for cardiac autonomic neuropathy. The incidence of cardiac autonomic neuropathy in treadmill positive group was 72.2% as compared to 31.0% in treadmill negative group, (p < 0.01). Nine patients from the positive group and 4 patients from the negative group were subjected for coronary angiography, which revealed significant CAD in 8 and 1 subjects in both groups respectively. It is concluded that the incidence of silent myocardial ischaemia in diabetics is very high and cardiac autonomic neuropathy seems to be the most probable reason for absence of pain.
