Abstract Objective: To explore the values of intravascular ultrasound in evaluating the stability of atherosclerotic plaques in patients with coronary heart disease. Methods: From February 2014 to December 2017, 122 patients with coronary heart disease were selected. All the patients were given intravascular ultrasound of coronary artery, the characteristics of ultrasound and the stability of atherosclerotic plaque were recorded, and the clinical data of the patients were investigated and the risk factors were evaluated. Results: There were 45 patients of unstable plaque were detected by intravascular ultrasound, and the detection rate was 36.9%. 21 patients of mild coronary artery stenosis were detected by intravascular ultrasound, 39 patients of moderate stenosis and 62 patients of severe stenosis, and the thickness of plaque, patch area and stenosis of unstable plaque were higher than those of stable plaque, and the difference were statistically significant(P<0.05). Two classified Logistic regression analysis showed that plaque thickness, plaque area, stenosis rate, Hcy and hs-CRP were independent risk factors for the occurrence of unstable plaques(P<0.05). Conclusion: The coronary artery intravascular ultrasound can effectively determine the stability of atherosclerotic plaque, and the characteristics of ultrasound are also the risk factors that affect the stability of plaque, and has certain reference value for predicting the occurrence of coronary heart disease.
