研究目的:

本研究旨在评估小剂量注射用重组人尿激酶原(rhPro-UK)冠状动脉内给药作为常规介入治疗的辅助手段的有效性和安全性。主要研究目标包括:1.明确其对 STEMI 患者 PCI 术后 TIMI 血流和心肌灌注的改善作用;2.评估其对介入治疗后心功能的影响;3.探讨其对ST 段抬高型心肌梗死( STEMI )患者远期主要不良心血管事件(MACE)的预防作用。同时,将系统评估其出血风险,以全面权衡其临床应用的获益与安全性。  

Objectives of Study:

This study aims to evaluate the efficacy and safety of low-dose intracoronary administration of recombinant human urokinase proenzyme (rhPro-UK) as an adjunct to conventional interventional therapy. The main research objectives include: 1.clarifying its improvement on TIMI flow and myocardial perfusion in patients with ST-elevation myocardial infarction(STEMI) after PCI; 2.assessing its impact on cardiac function post-interventional treatment; 3.exploring its preventive effect on major adverse cardiovascular events (MACE) in STEMI patients over the long term. Additionally, it will systematically assess bleeding risks to comprehensively balance the benefits and safety of its clinical application.MACE in STEMI patients. Simultaneously evaluate its therapeutic safety.
