Clinical practice guidelines recommend that patients with STEMI receive fibrinolytic therapy be given within 30 minutes of hospital arrival in patients with ST-elevation myocardial infarction (O Gara, 2013; Chew, 2016).
What is the primary time window for the administration of fibrinolytic therapy?

What is the golden hour for stroke patients?
A door-to-treatment time of 60 minutes or less is the goal. This 60-minute period is often referred to as the “golden hour” of acute ischemic stroke treatment during which a focused diagnostic workup must be completed to rule out conditions that may mimic stroke as well as contraindications to rt-PA administration.
What is the most common complication of fibrinolytic therapy?
The most feared complication of fibrinolysis is intracranial hemorrhage (ICH), but serious hemorrhagic complications can occur from bleeding at any site in the body. Risk factors for hemorrhagic complications include the following: Increasing age. Lower body weight.

What if thrombolysis does not work?

What is the treatment for stroke victims?
If you get to the hospital within 3 hours of the first symptoms of an ischemic stroke, you may get a type of medicine called a thrombolytic (a “clot-busting” drug) to break up blood clots. Tissue plasminogen activator (tPA) is a thrombolytic. tPA improves the chances of recovering from a stroke.
What happens after a small stroke?
