كيف تعرف الجلطة الدماغية في بدايتها

Quote: Medicines that dissolve blood clots ‘Clot-busters’ either digest fibrin fibres directly or activate natural mechanisms for doing so. The restoration of blood flow as soon as possible after stroke is crucial if brain damage is to be minimised. This is why it is so important to get someone who has had a stroke to hospital and to differentiate those with an ischaemic stroke from those with an haemorrhagic stroke. Clot-busters can be used in the former, but would be dangerous in the latter because they might perpetuate the bleeding. Several clot-busting medicines have been developed, including streptokinase (Pharmacia & Upjohn and Hoechst Marion Roussel), urokinase (Leo Pharmaceuticals and Serono), and alteplase (Boehringer Ingelheim), which is a recombinant tissue plasminogen activator (rt-PA). So far, alteplase is on the market only in the USA for the treatment of acute stroke within three hours, but it is expected to be available in Europe shortly. Both streptokinase and urokinase are marketed for other forms of thrombosis, including heart attack and deep vein thrombosis. Alteplase is available for heart attack and pulmonary embolism, but not deep vein thrombosis
