Insights
Intracoronary prourokinase improved ST-segment elevation myocardial infarction reperfusion without increasing bleeding. This treatment enhanced myocardial perfusion during primary percutaneous coronary interventions.
Area of Science:
- Cardiology
- Interventional Cardiology
- Pharmacology
Background:
- Acute ST-segment elevation myocardial infarction (STEMI) requires rapid reperfusion.
- Primary percutaneous coronary interventions (PCI) are standard, but improving microvascular reperfusion remains a challenge.
Purpose of the Study:
- To assess the efficacy and safety of intracoronary prourokinase administration during primary PCI in STEMI patients.
- To evaluate its impact on myocardial perfusion and clinical outcomes.
Main Methods:
- A randomized trial comparing intracoronary prourokinase (n=125) versus saline (control, n=135) during primary PCI in STEMI.
- Prourokinase or saline was delivered distally via balloon catheter post-dilatation.
- Evaluated infarct size, myocardial reperfusion (ST-resolution), cardiac function, bleeding, and major adverse cardiovascular events (MACE) at 6 months.
Main Results:
- Intracoronary prourokinase significantly increased ST-segment resolution (>50%) compared to control (P < 0.05).
- Patients receiving prourokinase showed lower serum CK, CK-MB, and troponin I levels (P < 0.05).
- No significant differences in bleeding complications or 6-month MACE were observed between groups (P > 0.05).
Conclusions:
- Intracoronary prourokinase administration via balloon catheter during primary PCI effectively enhances myocardial perfusion in STEMI.
- This approach is safe, with no increase in bleeding complications.
- It offers a potential adjunctive therapy to improve outcomes in STEMI patients undergoing primary PCI.
Objectives:
To evaluate the efficacy and safety of intracoronary administration of prourokinase via balloon catheter during primary percutaneous coronary interventions in patients with acute ST-segment elevation myocardial infarction.
Methods:
Acute ST-segment elevation myocardial infarction patients underwent primary percutaneous coronary interventions were randomly divided into two groups: intracoronary prourokinase group (n = 125) and control group (n = 135). During primary percutaneous coronary interventions, prourokinase or saline was injected to the distal end of the culprit lesion via balloon catheter after balloon catheter dilatation. Demographic and clinical characteristics, infarct size, myocardial reperfusion, and cardiac functions were evaluated and compared between two groups. Hemorrhagic complications and major averse cardiovascular events (MACE) occurred in the 6-months follow-up were recorded.
Results:
No significant differences were observed between two groups with respect to baseline demographic, clinical, and thrombolysis in myocardial infarction grade (P > 0.05). In the intracoronary prourokinase group, more patients had ST-segment resolution (>50%) compared with control group (P < 0.05). Patients in the intracoronary prourokinase group showed lower levels of serum CK, creatine kinase-MB fraction, and troponin I than those in control group (P < 0.05). No significant differences in bleeding complications were observed between the two groups (P > 0.05). At 6-months follow-up, there was no statistically different of MACE between the two groups (P > 0.05).
Conclusions:
Intracoronary administration of prourokinase via balloon catheter during primary percutaneous coronary interventions effectively improved myocardial perfusion and no increased bleeding in ST-segment elevation myocardial infarction patients.
