Abstract:
Objective To find out the sensitivity and s pecificity of intravascular ultrasound (IVUS) in identification of unstable atherosclerotic plaques. Methods Fourty-three patients diagnosed coronary heart disease, receiving coronary angiography and intravascular ultrasound examination,were divided into soft plaque and hard plaque group according to the echo reflectivity of atherosclerotic plaque by IVUS. Quantitative determination was performed between the two groups. Results The sensitivity of IVUS in detecting soft plaques from patients with acute coronary artery syndrome was 81.4 %, specificity 75.0 %, accuracy 79.1 %, positive predictive value 84.6 %. The lipid core areas and lipid to plaque ratio of soft plaques were significantly larger than those of hard plaques (P 0.05 ).Conclusions IVUS had higher sensitivity and specificity in detecting coronary vulnerable plaques in live bodies.
