RESUMO
We studied relationship between markers of endothelial dysfunction and multifocal atherosclerosis and adverse coronary events in 82 patients with non-ST segment elevation acute coronary syndrome (NSTEACS). Eighteen patients (21.9%) had adverse events during one year of observation. Patients with adverse coronary events had impaired vasodilatory, vasoconstrictive, and adhesive endothelial function. Predictors of unfavorable prognosis in NSTEACS were signs of impaired endothelium-dependent vasodilation during test with reactive hyperemia, high soluble platelet selectin and endothelin-1 levels on day 10 of the disease. Endothelin-1 and soluble platelet-endothelial cell adhesion molecule-1 had greatest predictive power relative to development of non-fatal myocardial infarction.
