Patterns of coronary plaque progression: phasic versus gradual. A combined optical coherence tomography and intravascular ultrasound study
Objective: Some plaques grow slowly in a linear manner, whereas others undergo a rapid phasic progression. However, the detailed in-vivo relationship between plaque characteristics and plaque progression pattern has not been reported. The current study aimed to investigate the plaque progression patterns with serial intravascular ultrasound (IVUS) examinations, and to correlate baseline plaque characteristics assessed by optical coherence tomography and IVUS with plaque progression patterns. Methods: A total of 248 coronary lesions from 157 patients were identified and imaged by both optical coherence tomography and IVUS at baseline. IVUS examination was repeated at 6 and 12 months. Plaque progression was ...
