Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter.

Patients at low risk can be adequately treated with medical therapy, in many ways similar to the one used for STEMI (but excluding thrombolytics). Those at moderate to high risk benefit from an early invasive strategy, which includes coronary angiography and, if necessary, revascularization with percutaneous coronary intervention or coronary ...
The following patients are at an increased risk for bleeding complications due to drotrecogin-alpha therapy, and a careful risk/benefit assessment should be made prior to initiating therapy. Therapeutic Heparin (>15 units/kg/h) Platelet count <30,000/mm3; Recent (within 6 weeks) gastrointestinal bleeding
Thrombolysis, also called fibrinolytic therapy, is the breakdown of blood clots formed in blood vessels, using medication. It is used in ST elevation myocardial infarction , stroke , and in cases of severe venous thromboembolism (massive pulmonary embolism or extensive deep vein thrombosis ).
The PLATO trial [39] found that ticagrelor use, in conjunction with low-dose aspirin (where tolerated), had better all-cause mortality rates than the same treatment plan with clopidogrel (4.5% vs. 5.9%) in treating people with acute coronary syndrome. People given ticagrelor were less likely to die from vascular causes, heart attack, or stroke ...
Thrombolysis is most effective in the first 2 hours. After 12 hours, the risk of intracranial bleeding associated with thrombolytic therapy outweighs any benefit. [3] [6] [7] Because irreversible injury occurs within 2–4 hours of the infarction, there is a limited window of time available for reperfusion to work. [citation needed]
