Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this prospective cohort study is to investigate the relationship between the TyG index and early identification of MVO in AMI patients undergoing emergency PCI and CMR imaging. The study will enroll approximately 300 AMI patients treated at Xiangya Third Hospital of Central South University from June 2024 to August 2025. The main questions it aims to answer are:

* How does the TyG index correlate with the early detection of MVO?
* What differences in cardiovascular adverse events during hospitalization exist between groups with varying TyG index levels? Participants will undergo emergency PCI and CMR imaging within 3-7 days post-procedure. Data collected will include demographic characteristics, clinical history, coronary angiography data, laboratory test indicators (especially metabolic markers such as blood glucose and lipids), IVUS-related plaque information, and CMR results.
