Plaque location and vessel geometry ‘offer prognostic value for ACS’
Geometric features seen on imaging can provide vital information on the threat of progression to dangerous lesions, researchers find
Coronary plaques with adverse geometric traits, such as proximity to the ostium, are associated with progression to acute coronary syndrome-causing culprit lesions, a first-of-its-kind study shows.
The findings demonstrate that assessing plaque location and vessel geometry “may provide additive prognostic information” in coronary CT angiography (CCTA), an international research group says.
Using a combination of visual assessment and simple distance and angle measurements, the US-led team investigated the relationship between lesion-level adverse geometric characteristics (see box below) and risk of developing into culprit lesions.
Coronary lesions were evaluated for three adverse geometric characteristics:
