[Asymptomatic ischemia in coronary arterial ectasia. Effects of anticoagulation].
We studied 23 patients (22 men and 1 woman), their ages ranged from 31 to 71 years (55.9 +/- 9.7 years), with isolated coronary arterial ectasia. Seventeen patients presented angina pectoris, 19 had myocardial infarction. An angiographic image of intracoronary thrombus was observed in 5 patients. Before the administration of anticoagulants (oral warfarin) 16 patients showed unstable angina, the exercise EKG was positive in 9 patients, and 16 patients presented silent ischemia (showed by EKG-Holter), whose duration was 35.21 +/- 29.27 min per day. After anticoagulants, only 5 patients showed unstable angina pectoris. Exercise EKG was positive in 7 patients and only 7 patients showed silent ischemia, whose duration decreased significantly (P < 0.001) to 12.47 +/- 22.5 min per day.
