研究目的:

目前心血管领域研究的热点和难点之一是如何精准预测和早期防治急性心肌梗死(AMI)患者经皮冠状动脉介入治疗(PCI)术后主要心血管不良事件(MACE)的发生。国内外关于斑点追踪技术(STI)和左房室耦合指数(LACI)在评估AMI患者短期生存预后的研究较为有限。本研究旨在探讨STI联合LACI对AMI患者PCI术后发生MACE的预后价值。  

Objectives of Study:

One of the current research hotspots and challenges in the cardiovascular field is how to accurately predict and early prevent major adverse cardiovascular events (MACE) in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Research on speckle tracking imaging (STI) and left atrial-ventricular coupling index (LACI) in evaluating the short-term survival prognosis of AMI patients is relatively limited at home and abroad. This study aims to explore the prognostic value of STI combined with LACI for the occurrence of MACE after PCI in AMI patients.
