Relationship between coronary high-intensity plaques on T1-weighted imaging by cardiovascular magnetic resonance and vulnerable plaque features by near-infrared spectroscopy and intravascular ultrasound: a prospective cohort study

Table 3 Univariable and multivariable logistic regression analysis for prediction of HIP (PMR ≥ 1.4)

Variable	Univariable		Multivariable
Variable	OR (95% CIs)	p value	OR (95% CIs)	p value
NIRS-derived large LRP (maxLCBI_4mm ≥ 400)	6.17 (2.01–18.9)	< 0.001	5.41 (1.65–17.8)	0.005
IVUS-derived echo-lucent plaque	4.83 (1.18–19.8)	0.018	5.12 (1.11–23.6)	0.036
IVUS-derived plaque burden of ≥ 70%	2.24 (0.78–6.41)	0.130	1.89 (0.57–6.33)	0.300
IVUS-derived attenuated plaque	2.20 (0.78–6.19)	0.132

CIs, confidence intervals; HIP, high-intensity plaque; IVUS, intravascular ultrasound; LRP, lipid-rich plaque; NIRS, near-infrared spectroscopy; maxLCBI_4mm, maximum lipid core burden index calculated for every 4-mm segment; OR, odds ratio; PMR, plaque-to-myocardial signal intensity ratio
