sackatdoc - 09-27-08 06:07 heparin maintains t-PA induced coronary aretery patency more effectively
heparin has not been found to outweigh the harms in patients receiving streptokinase,except in pts with anterior wall MI, or pts. with complications prone to thromboembolism such as ATRIAL FIB and CCF

Re: Role of Heparin yehia1982 - 10-24-08 17:12 Unfractionated intravenous heparin and fractionated low molecular weight subcutaneous heparins are the two choices for initial anticoagulation therapy.
Augments activity of antithrombin III and prevents conversion of fibrinogen to fibrin. Does not actively lyse but is able to inhibit further thrombus formation. Prevents reaccumulation of clot after spontaneous fibrinolysis.
