High-Frequency QRS for Predicting Microvascular Dysfunction and Adverse Events After PCI in Acute Myocardial Infarction
Sponsor: The Affiliated Hospital of Xuzhou Medical University
Summary
This observational study aimed to investigate the prognostic value of high-frequency QRS (HF-QRS) in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI), as well as its potential role in diagnosing microvascular dysfunction. The main question it aims to answer is: 1. Whether HF-QRS could serve as an effective tool for early identification of high-risk AMI patients and prognosis prediction; 2. Whether HF-QRS provides auxiliary diagnostic value for post-AMI microvascular dysfunction. Participants underwent HF-QRS assessment and were prospectively followed for 1 year to record the incidence of major adverse cardiovascular events (MACE).
