Brief Summary:
Identifying the critical lesion of coronary artery disease and determining the interventional plan are significant for reducing adverse cardiovascular adverse events. The assessment of critical lesion requires the consideration of plaque morphology, tissue composition, and endometrial stress which leading to rupture. In summary, accurate assessment of critical lesions has high application value. In this study, patients with critical coronary artery disease were divided into two groups: an accurate assessment group and a simple assessment group, with the aim to compare the diagnosis and treatment efficiency as well as prognosis, potential cardiovascular risk, possible "excessive" intervention.
