The clinical value of ultra-high-end spiral CT single-heartbeat cardiac technique in identifying coronary artery stenosis and plaque properties and the influence of underlying diseases on accuracy
摘要
Abstract
Objective:To investigate the clinical value of ultra-high-end spiral CT single-heartbeat cardiac technique in identifying coronary artery stenosis and plaque properties and the influence of underlying disease on accuracy.Methods:Nine-ty-six patients with coronary heart disease diagnosed and treated in our hospital from July 2022 to January 2023 were select-ed as research objects.According to the degree of coronary artery stenosis,33 patients with grade Ⅰ disease,22 patients with grade Ⅱ disease,and 41 patients with grade Ⅲ disease were selected.According to the analysis of plaque properties,55 patients with stable plaque and 41 patients with unstable plaque were enrolled.All patients underwent 256-slice CT for single-heartbeat coronary artery imaging,coronary angiography(ICA)and intravascular ultrasound(IVUS).The diagnostic efficacy of single-heartbeat coronary artery imaging in the diagnosis of coronary artery stenosis and unstable plaque was compared.The effect of comorbidities with underlying diseases on accuracy was studied.Result:The sensitivity of single-heartbeat coronary imaging for diagnosing grade Ⅲ coronary stenosis was 80.49%,and the area under ROC curve of single-heartbeat coronary imaging for diagnosing grade Ⅲ coronary stenosis was 0.771,which was complicated with hypertension,diabetes,hyperlipi-demia,etc.It can reduce the efficiency of single-heartbeat coronary imaging in diagnosing grade Ⅲ coronary artery stenosis.The sensitivity of single-heartbeat coronary imaging in diagnosing unstable plaque was 80.21%,and the area under ROC curve of single-heartbeat coronary imaging in diagnosing unstable plaque was 0.775.Combined with hypertension,diabetes,hyperlipidemia,etc.,the diagnostic efficiency of single-heartbeat coronary imaging in diagnosing unstable plaque decreased.Conclusion:The sensitivity of ultra-high-end spiral CT single-heartbeat cardiac technology to identify coronary artery stenosis and plaque properties is more than 80%.Patients with hypertension,diabetes and hyperlipidemia will result in the decline of the accuracy and sensitivity of coronary artery stenosis and plaque properties.关键词
