老年冠心病患者颈动脉硬化应用超声诊断的准确性及灵敏性分析

Analysis on Accuracy and Sensitivity of Ultrasound in the Diagnosis of Carotid Atherosclerosis in Elderly Patients with Coronary Heart Disease

目的:探讨老年冠心病患者颈动脉硬化标准应用超声诊断的准确性及灵敏性。方法:2020年4月-2021年6月,抽取473例老年冠心病患者展开研究,均给予超声诊断,基于颈动脉硬化标准进行诊断,颈动脉内-中膜厚度(IMT)<1.5mm患者无颈动脉硬化,≥1.5mm患者有颈动脉硬化,将血管造影检查结果作为金标准。结果:超声诊断的敏感度是97.81%、特异度是94.12%、准确性是97.67%。结论:基于颈动脉硬化标准,采用超声诊断可及时诊出老年冠心病颈动脉硬化患者,具有显著的应用价值。

Objective: To investigate the accuracy and sensitivity of ultrasound diagnosis of carotid atherosclerosis in elderly patients with coronary heart disease. Methods: From April 2020 to June 2021, 473 elderly patients with coronary heart disease were selected for the study, and all were diagnosed by ultrasound. The diagnosis was made based on carotid arteriosclerosis standards. There was no carotid arteriosclerosis in patients with carotid artery-media thickness(IMT)<1.5 mm, patients with IMT ≥1.5 mm have carotid atherosclerosis, and the angiography results are regarded as the gold standard. Results: The sensitivity of ultrasound diagnosis was 97.81%, the specificity was 94.12%, and the accuracy was 97.67%. Conclusion: Based on the criteria of carotid atherosclerosis, ultrasound diagnosis can timely diagnose elderly patients with coronary artery disease and carotid atherosclerosis, which has significant application value.
