There are two broad types of thrombolytic drugs, one for intra-arterial thrombolysis and the other for intravenous thrombolysis. The most common intra-arterial thrombolysis is to dissolve the thrombus in the artery through the catheter from the radial artery to the coronary artery, and then use drugs such as streptokinase and urokinase to achieve the purpose of revascularization. However, this operation requires high requirements for the environment and operators, so it can only be performed in specialized cardiology departments or cardiac specialists in tertiary hospitals. Intravenous thrombolysis is relatively simple and easy to perform, and can be performed in general hospitals through intravenous drip of streptokinase, and then thrombolysis, which can achieve an efficiency of 50%-90% with 500 to 1.5 million units of streptokinase within 30 minutes, relieving the symptoms of chest pain and saving and protecting the heart muscle. Both thrombolytic approaches carry the risk of causing bleeding, an unavoidable side effect of thrombolytic drugs.
