摘要
目的 研究心脏超声联合颈部血管超声(CVUS)在老年冠心病(CHD)诊断中的应用价值。方法 选取漯河市中心医院2018年1月至2021年12月收治的64例疑似老年CHD患者为研究对象,所有患者均进行心脏超声与CVUS检查[包含斑块积分及颈动脉内中膜厚度(IMT)],以冠状动脉造影为“金标准”,分析心脏超声、CVUS及二者联合检查的诊断结果、诊断效能,分析斑块积分和IMT变化。结果 本研究64例疑似老年CHD患者中,经冠状动脉造影诊断出阳性61例,阴性3例;经心脏超声诊断出阳性49例,阴性15例,其中真阳性48例,真阴性2例,假阳性1例,假阴性13例;经CVUS诊断出阳性52例,阴性12例,其中真阳性51例,真阴性2例,假阳性1例,假阴性10例;二者联合诊断出阳性59例,阴性5例,其中真阳性59例,真阴性3例,假阳性0例,假阴性2例。二者联合诊断灵敏度为96.72%(59/61)、准确度为96.88%(62/64),高于心脏超声诊断[78.69%(48/61)、78.13%(50/64)]、CVUS诊断[83.61%(51/61)、82.81%(53/64)],且二者联合诊断漏诊率为3.28%(2/61),低于心脏超声诊断[19.67%(12/61)]、CVUS诊断[16.39%(10/61)],差异有统计学意义(P<0.05)。与阴性患者比较,阳性患者斑块积分、IMT较高,差异有统计学意义(P<0.05)。结论 心脏超声联合CVUS诊断老年CHD患者可以提高诊断效能,反映斑块积分、IMT变化。
Objective To investigate the application value of cardiac ultrasound combined with cervical vascular ultrasound(CVUS)in the diagnosis of elderly coronary heart disease(CHD).Methods Sixty-four suspected elderly patients with CHD in Luohe Central Hospital from January 2018 to December 2021 were selected.All patients underwent cardiac ultrasonography and CVUS examination[induding plaque score and carotid intima-media thickness(IMT)]J.Coronary angiography was used as the'gold standard"to analyze the diagnostic results and diagnostic efficacy of cardiac ultrasonography,CVUS and their combined examination,and to analyze the changes of plaque score and IMT.Results Among the 64 suspected elderly patients with CHD,61 cases were positive and 3 cases were negative diagnosed by coronary angiography.There were 49 positive cases and 15 negative cases diagnosed by cardiac ultrasonography,including 48 true positive cases,2 true negative cases,1 false positive case and 13 false negative cases.Fifty-two positive and 12 negative cases were diagnosed by CVUS,including 51 true positive cases,2 true negative cases,1 false positive case and 10 false negative cases.Fifty-nine cases were positive and 5 cases were negative diagnosed by the combined examination,among which 59 cases were true positive,3 cases were true negative,O cases was false positive and 2 cases were false negative.The sensitivity and accuracy of the combined diagnosis were 96.72%(59/61)and 96.88%(62/64),which were higher than those[78.69%(48/61),78.13%(50/64)]of cardiac ultrasound diagnosis,those[83.61%(51/61)and 82.81%(53/64)] of CVUS diagnosis,and the missed diagnosis rate of the combined diagnosis was 3.28%(2/61),which was lower than that[19.67%(12/61)]of cardiac ultrasound diagnosis and that[16.39%(10/61)]of CVUS diagnosis,and the differences were significant(P<0.05).Compared with negative patients,the plaque score and IMT of positive patients were higher,and the differences were significant(P<0.05)Conclusions Cardiac ultrasound combined with CVUS in the diagnosis of elderly patients with CHD ca improve the diagnostic efficiency,and can reflect the changes of plaque integration and IMT.
