Brief Summary

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

This study aimed to evaluate the incidence of preinfarction angina in AMI patients and test the hypothesis that different clinical presentations before AMI onset can affect coronary plaque morphologies in AMI patients .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with AMI who underwent primary percutaneous coronary intervention（PCI） and optical coherence tomography (OCT) examination is expected to be included in this study.Data about history were prospectively collected by a standard questionaire ,especially regarding the detail information about preinfarction angina.The basic clinical characteristics,angiographic and OCT findings are compared between patients with and without preinfarction angina.
