摘要目的:探讨256排CT检查在心肌梗死患者诊断中的应用价值。方法:回顾性分析本院2022年6月~2023年4月收治的146例心肌梗死患者的临床资料,患者均进行冠状动脉造影(CAG)检查,将其结果作为“金标准”,患者在CAG之前接受超声心动图和256排CT检查,对不同检测方式所反映的冠脉血管病变程度及心功能指标进行比较。结果:CAG共检测1334支冠状动脉节段,其中638支(47.83%)无异常,247支(18.52%)为轻度狭窄,260支(19.49%)为中度狭窄,189支(14.17%)为重度狭窄;256排CT在轻度、中度、重度冠状动脉狭窄患者诊断中的敏感度、特异度、准确率均高于超声心动图(P<0.05);256排CT与超声心动图在ESV、EDV、EF及SV等指标的检查结果比较无明显统计学差异(P>0.05)。结论:在心肌梗死患者冠脉血管病变程度上,256排CT检测有着更高的诊断效能,但在心功能指标上与超声心动图比较诊断结果相似。 Objective:To explore the application value of 256-slice CT examination in the diagnosis of myocardial infarction patients.Methods:The clinical data of 146 patients with myocardial infarction admitted to our hospital from June 2022 to April 2023 were retrospectively analyzed.All patients underwent coronary angiography(CAG),and the results were taken as the“gold standard”.Before receiving echocardiography and 256-slice CT examination,the degree of coronary vascular disease and cardiac function indicators reflected by different detection methods were compared.Results:A total of 1334 coronary artery segments were detected by CAG,Among them,638(47.83%)had no abnormality,247(18.52%)had mild stenosis,260(19.49%)had moderate stenosis,and 189(14.17%)had severe stenosis;The sensitivity,specificity and accuracy of 256-slice CT in the diagnosis of patients with mild,moderate and severe coronary stenosis were higher than those of echocardiography(P<0.05);There was no significant difference in the examination results of ESV,EDV,EF and SV between 256-slice CT and echocardiography(P>0.05).Conclusion:256-slice CT has a higher diagnostic performance in the degree of coronary vascular disease in patients with myocardial infarction,but it has similar diagnostic results with echocardiography in cardiac function indicators.
