Yi. Zharov et al., SILENT-MYOCARDIAL-ISCHEMIA IN PATIENTS WI TH DIABETES-MELLITUS WITHOUT CLINICAL SIGNS OF CORONARY HEART-DISEASE, Kardiologia, 33(6), 1993, pp. 16-18
A total of 40 patients with diabetes mellitus without anginal episodes
and equivalents were studied. 24-hour monitoring identified 2 groups
of patients: (1) 13 patients with recorded silent myocardial ischemic
episodes and (2) 23 patients without episodes. Four patients were foun
d to have stress-echocardiograpgic silent myocardial ischemia. Silent
myocardial ischemia was detected in 42.5 % of patients with diabetes m
ellitus. The patients from Group 1 exhibited more frequently Type II d
iabetes mellitus whose duration was over 9 years and concurrent retino
- and polyneuropathies. There was a relationship between silent myocar
dial ischemia to heart failure and myocardial hypertrophy as evidenced
by two-dimensional echocardiography. The patients from Group 1 had a
higher pain sensitivity threshold than those from Group 2. Autonomic p
olyneuropathy was observed in 46 % of Group 1 patients and in 21 % of
Group 2 patients.
