Overview

Effect of Complementary Intracoronary Streptokinase Administration Immediately After Primary Percutaneous Coronary Intervention on Microvascular Perfusion and Late Term Infarct Size in Patients With Acute Myocardial Infarction

Status:
Completed
Trial end date:
2008-02-01
Target enrollment:
0
Participant gender:
All
Summary
The investigators hypothesized that complementary intracoronary streptokinase administration to primary percutaneous intervention in patients with acute myocardial infarction may provide further improvement in myocardial perfusion by dissolving microvascular thrombus [in situ formed or embolized from proximal site (spontaneous or following PCI)] and fibrin.
Phase:
Phase 4
Accepts Healthy Volunteers?
No
