About

Patients with acute ST-segment elevation myocardial infarction and thrombolysis indications, will be given the recombinant human prourokinase for thrombolysis treatment, and in accordance with the guidelines, will be treated with coronary angiography examination 3 to 24 hours after thrombolysis. The study will explore the best time for interventional therapy combined with thrombolysis.

Full description

The noninferiority multicenter, prospective, randomized, controlled study of urokinase of restructuring the original design evaluation (rhPro - UK) at different times after thrombolysis combined with percutaneous coronary intervention（PCI）therapy of acute ST segment elevation myocardial infarction.Patients with acute ST segment elevation myocardial infarction and thrombolysis indications, will be given the recombinant human prourokinase for thrombolysis treatment, and in accordance with the guidelines, will be treated with coronary angiography examination 3 to 24 hours after thrombolysis. The study will explore the best time for interventional therapy combined with thrombolysis.

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

120 participants in 2 patient groups

A group

Experimental group

Description:

STEMI patients first are given thrombolysis and then transfer to PCI center to be treated by PCI 3-6 hours after thrombolysis if the thrombolysis is successful. if the thrombolysis is not successful, patients will be treated by PCI immediately.

Treatment:

Combination Product: thrombolysis and PCI of A type

B group

Experimental group

Description:

STEMI patients first are given thrombolysis and then transfer to PCI center to be treated by PCI 6-24 hours after thrombolysis if the thrombolysis is successful. if the thrombolysis is not successful, patients will be treated by PCI immediately.

Treatment:

Combination Product: thrombolysis and PCI of B type
