[Data of coronary angiography and rheological properties of erythrocytes in non ST-elevation acute coronary syndrome].

We assessed character and extent of coronary vessels involvement in 27 patients with non ST-elevation acute coronary syndrome (NSTEACS) and compared angiography data with rheological properties of erythrocytes of patients and 30 practically healthy men. Stenoses of main branches of coronary vessels were found almost in 3/4 of cases. In 4 patients without stenoses in main branches of coronary arteries we revealed lowering of blood flow velocity related to small vessel disease (syndrome X). In 2 cases there were no changes in coronary circulation. Extent of vessel involvement was the least in patients with non Q-wave myocardial infarction as initial manifestation of ischemic heart disease and the greatest in patients with unstable angina after myocardial infarction. Patients with NSTEACS had elevated aggregation capacity and lowered deformability of erythrocytes. Degree of these changes did not depend on clinical peculiarities of development of the disease, extent of obstructions, character of vessels involvement. Positive correlation between was found content of cholesterol and degree of elevation of rate of erythrocyte aggregation.
