A study has been made of 31 patients with coronary heart disease where diagnosis had been clearly ascertained both from a clinical and strumental point of view. All patients had undergone aorto-coronary by-pass surgery. The controls of the parameters under observation (whole-blood and plasmatic viscosity, hematocrit, fibrinogen, euglobulin lysis, T protothrombin, T of partial thromboplastin, thromboelastogram antithrombin III, plasminogen, alfa2-macroglobulin and fractions C'3c, C'3c, C'4 of the complement) were carried out as follows: basic sample taken, I control (8th-10th day), II control (15th-20th day), III control (45th-50th day), IV control (85th-90th day) after surgical operation. A global examination of our results showed significant changes in the rheologic coagulative and fibrinolytic parameters after an aorto-coronary surgical operation. The slight tendency toward hypercoagulability met with in the basic blood sample (slight increase of whole-blood viscosity, hyperfibrinogenemy, inhibition of fibrinolytic activity) does not change significantly after surgical operation. This seems to indicate that the coronary by-pass does not in any way alter the evolution of arteriosclerosis.

D001809 Blood Viscosity The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.

D003176 Complement C3 A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.

D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
