| pubmed-article:2959943 | pubmed:abstractText | From October 1983 to January 1985, 46 patients (38 men and 8 women; mean age 60 years, range 37-83) underwent peripheral vascular surgery either of the internal carotid artery or of arteries of the lower limbs. All patients had thorough clinical examination, ECG and thallium dipyridamole myocardial scanning before operation, as a result of which they were divided into 20 with, and 26 without chronic ischemic heart disease. Three major cardiac events were noted during or following a period of one month after surgery: two deaths due to a cardiac ischemic event and one post-operative unstable angina pectoris. The three patients with these complications were classified in the coronary group (NS). When the patients were reclassified according to the presence or absence of thallium redistribution on serial images after dipyridamole, 14 had redistribution and 32 had no redistribution. The three major cardiac events were found to have occurred in the group with redistribution (P less than 0.04). Our study suggests that patients with redistribution have a high incidence of postoperative ischemic events. They should be considered for a particular pre-operative coronary management to avoid post-operative major cardiac events and to improve survival. | lld:pubmed |
