An observational study in AMI, sponsored by The Affiliated Hospital of Xuzhou Medical University. Not yet recruiting at 1 site in China. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2025-08-24.
Sponsored by The Affiliated Hospital of Xuzhou Medical University · Observational
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:
Participants underwent HF-QRS assessment and were prospectively followed for 1 year to record the incidence of major adverse cardiovascular events (MACE).
The Affiliated Hospital of Xuzhou Medical University is the lead sponsor of 66 studies on the registry; 31 are open to participants now.

All enrolled patients underwent HF-QRS assessment, with subsequent recording of MACE to evaluate the predictive value of HF-QRS parameters for clinical outcomes
To evaluate the predictive value of high-frequency QRS (HF-QRS) parameters for major adverse cardiovascular events (MACE) within 1 year after PCI in AMI patients and to construct a prognostic risk prediction model.
Time frame: 12 months
To evaluate the adjunctive diagnostic value of high-frequency QRS parameters for microvascular dysfunction in ACS patients following percutaneous coronary intervention
