Abstract

In this study we compaired the endothelium function in patients with different forms of acute coronary syndromes (ACS), using the brachial artery flow-mediated dilation (FMD) test. One hundred twelve patients with ACS were included in the study. The patients were divided into two groups: group 1 (n=52), consisting of patients with ST elevation acute myocardial infarction (STEMI) and group 2 (n=60), consisting of patients with ACS without ST elevation. There were no significant differences of the FMD levels between these two groups. Then patients with ACS without ST elevation were divided in two subgroups: 2a (n=38) patients without ST elevation myocardial infarction (non STEMI), 2b (n=22) patients with unstable angina. There were no significant differences between the brachial artery FMD test in these subgroups. STEMI patients were divided into two subgroups too, on the basis of the results of coronary angiography: subgroup 1a (n=33), consisting of patients with remaining total occlusion of the infarct-related artery (IRA), and subgroup1b (n=19), consisting of patients with spontaneous thrombolysis. In subgroup 1b during the first 3 days of STEMI, brachial artery FMD results were significantly higher than those in subgroup 1a (13,07±7,78 vs 6,23±4,77; р<0,0001) and that of patients with unstable ungina. In conclusion: patients with spontaneous thrombolysis have higher results of FMD test as compared with other groups of patients with ACS.
