High-Frequency QRS for Predicting Microvascular Dysfunction and Adverse Events After PCI in Acute Myocardial Infarction

NCT07138638 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 1112

Last updated 2025-08-24

No results posted yet for this study

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).
