Mathematical formulation of post-occlusion hyperaemia and autoregulation of blood flow in the capillaron model.

abstract：OBJECTIVES:Coronary artery often reoccludes after thrombolytic therapy with recombinant tissue-plasminogen activator (rt-PA). This reocclusion is thought to be due to in situ platelet activation mediated by thromboxane (Tx) A2 and thrombin; hence, aspirin and thrombin inhibitors are often used in patients with acute my...
