Natural History of Coronary Atherosclerosis Based on Multimodal Imaging and Physiological Fusion Techniques (NASCENT)
The present study sought to explore the predictive value of radial wall strain (RWS, derived solely from angiograms) for coronary artery lesion progression compared with lesion vulnerability assessed by optical coherence tomography (OCT). The lesion progression at 1 year was defined as an increase of ≥20% in diameter stenosis based on quantitative coronary angiography (QCA) evaluation.
• General Inclusion Criteria:
‣ Age ≥18 years
⁃ Acute myocardial infarction ≤ 45 days
⁃ Planned coronary angiography examination or potential interventional treatment
• Angiographic Inclusion Criteria:
‣ The presence of at least 1 non-flow-restricting lesion (visually estimated diameter stenosis: 30%-80%; QFR \> 0.80) in any non-infarct related artery with RVD ≥2.5 mm by visual assessment
