Natural History of Coronary Atherosclerosis
Recruiting now
Conditions studied: Coronary Artery Disease Progression, Radial Wall Strain, Atherosclerotic Lesion, Optical Coherence Tomography
In brief
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.

You may qualify if…
- 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
You may not qualify if…
