研究目的: |
1.本研究旨在系统性评估直接经皮冠状动脉介入治疗(pPCI)联合注射用重组链激酶冠脉内溶栓方案,对急性ST段抬高型心肌梗死(STEMI)患者冠脉微循环灌注的改善效能的有效性及安全性,探寻pPCI联合注射用重组链激酶冠脉内给药方案对STEMI患者预后的影响,为该联合治疗方案的临床转化与推广应用,提供高级别、高质量的循证医学证据支撑。 2.通过多中心、更大样本量的临床研究设计,进一步验证pPCI联合冠脉内重组链激酶溶栓治疗在STEMI患者冠脉微循环改善中的有效性及安全性,为该治疗方案在不同临床亚组(如不同年龄、合并症类型患者)中的精准应用及临床指南优化提供实践依据。 3.评估pPCI联合注射用重组链激酶冠脉内溶栓方案对STEMI患者梗塞血管梗死面积的改善作用。 |

Objectives of Study: |
1. This study aims to systematically evaluate the efficacy and safety of primary percutaneous coronary intervention (pPCI) combined with intracoronary thrombolysis with recombinant streptokinase for injection in improving coronary microcirculation perfusion in patients with acute ST-segment elevation myocardial infarction (STEMI). It also explores the prognostic impact of intracoronary administration of recombinant streptokinase combined with pPCI on STEMI patients, so as to provide high-level and high-quality evidence-based medical support for clinical transformation and popularization of this combined therapeutic regimen. 2. Designed as a multicenter clinical study with a larger sample size, this study further verifies the efficacy and safety of pPCI combined with intracoronary recombinant streptokinase thrombolysis in improving coronary microcirculation among STEMI patients, and provides practical evidence for the precise application of this regimen in different clinical subgroups (e.g. patients of different ages and with different comorbidities) and the optimization of clinical guidelines. 3. To assess the effect of pPCI combined with intracoronary thrombolysis using recombinant streptokinase for injection on reducing infarct size of occluded vessels in STEMI patients. |
