Answer

Anticoagulants, Cardiovascular

These agents are indicated in patients with VAD to prevent recurrent or ongoing thromboembolic occlusion of vertebrobasilar circulation.

Heparin

Potentiates antithrombin III activity. Does not actively lyse, but blocks further thrombogenesis. Prevents reaccumulation of a clot after spontaneous fibrinolysis. aPTT value 1.5-2 times control (50-80 s) is considered therapeutic.

Warfarin (Coumadin)

For prophylaxis and treatment of venous thrombosis, pulmonary embolism, and thromboembolic disorders. Interferes with hepatic vitamin K-dependent carboxylation. Usually prolongs PT in 48 h.
