New insights into fibrous cap thickness of vulnerable plaques assessed by optical coherence tomography

Abstract

Abstract Objective Vulnerable plaques with fibrous cap thickness (FCT) of ≤65 μm are prone to rupture and/or thrombosis. However, plaques with FCT > 65 μm cause acute myocardial infarction and even sudden death. We aimed to investigate the relationship between 65 80 μm, n = 271). Clinical and laboratory data was collected from the inpatient medical record system. Results Plaques with thinner FCT, especially 80 μm (P 80 μm]: OR = 8.082, 95% CI = 4.861 to 13.435, P 80 μm]: OR = 2.463, 95% CI = 1.370 to 4.430, P = 0.003), thrombosis ([FCT ≤ 65 μm vs. FCT > 80 μm]: OR = 25.224, 95% CI = 13.768 to 46.212, P 80 μm]: OR = 3.675, 95% CI = 2.065 to 6.542, P 80 μm]: OR = 22.593, 95% CI = 11.426 to 44.674, P 80 μm]: OR = 4.143, 95% CI = 1.869 to 9.184, P 80 μm.
