MSCT检查冠心病的应用及临床价值分析

目的探讨冠心病患者多层螺旋CT(MSCT)重建技术诊断效能及其危险因素分析。方法选取我院收治的102例疑似冠心病患者作为观察对象,均接受心电图(ECG)、MSCT重建技术检查。以冠状动脉造影检查(GAG)为金标准,统计MSCT重建技术及ECG冠心病及对不同冠状动脉狭窄程度诊断效能,logistic回归分析冠心病形成影响因素。结果1)102例疑似冠心病患者中,确诊78例冠心病,以此为根据分为冠心病组(n=78)和正常组(n=24);2)合并高血压、合并糖尿病、合并高脂血症、长期吸烟史、冠心病家族史、长期酗酒史是导致冠心病形成危险因素(P<0.05);3)以GAG检查结果为金标准。MSCT重建技术诊断准确度、敏感度、特异度高于ECG检查(P<0.05);4)MSCT重建技术对≥50%及≥75%冠状动脉狭窄诊断准确度、敏感度、特异度高于ECG检查(P<0.05)。结论MSCT重建技术可提高冠心病患者诊断价值,为临床选取合理诊治提供依据。

Analysis of diagnostic efficiency and risk factors of MSCT reconstruction in patients with coronary heart disease

Objective To explore the diagnostic efficacy and risk factors of multi-slice spiral CT(MSCT)reconstruction in patients with coronary heart disease.Methods 102 patients with suspected coronary heart disease admitted in our hospital from July 2016 to July 2018 were selected as the research subjects,and all were examined by electrocardiogram(ECG)and MSCT reconstruction techniques.Coronary angiography(GAG)was used as the gold standard.MSCT reconstruction technology,ECG coronary heart disease,and diagnostic efficacy for different degrees of coronary artery stenosis were statistically analyzed.Logistic regression was used to analyze the influencing factors of coronary heart disease formation.Results 1)Of the 102 patients with suspected coronary heart disease,78 were diagnosed with coronary heart disease.Based on this,they were divided into coronary heart disease group(n=78)and normal group(n=24).2)The hypertension and diabetes combined with hyperlipidemia,long-term smoking history,family history of coronary heart disease,and long-term alcoholism were risk factors for coronary heart disease formation(P<0.05);3)GAG test results were the gold standard.The diagnostic accuracy,sensitivity,and specificity of the MSCT reconstruction technique were higher than those of the ECG examination(P<0.05);4)The accuracy,sensitivity,and specificity of the MSCT reconstruction technique wre greater than 50%and≥75%in diagnosis of coronary stenosis by ECG examination(P<0.05).Conclusion MSCT reconstruction technology can improve the diagnostic value of patients with coronary heart disease.At the same time,it is found that the formation of coronary heart disease is related to long-term drinking history,family history,combined diabetes,and hypertension.It is recommended that the above factors be controlled clinically to reduce the incidence of coronary heart disease.
