Abstract:
Objective To explore the value of automated functional imaging(AFI)in predicting coronary artery stenosis in patients without ventricular wall motion abnormalities.Methods A total of 40 patients without ventricular wall motion abnormalities under two-dimensional echocardiography and confirmed coronary artery heart diseases(CHD)(coronary stenosis≥70%)by coronary angiography(CAG)at the Xinxiang Central Hospital from July 2018 to September 2019 were selected as the research subjects.The detection rates of coronary artery stenosis ≥70%by AFI and CAG were compared.With reference to CAG as the gold standard,the predictive value of AFI for coronary artery stenosis ≥70%was evaluated.Results There was no significant difference in the detection rates of coronary artery stenosis ≥70%by AFI and CAG(x2=1.667,P>0.05).The predictive efficacy of AFI for coronary artery stenosis ≥70%was as follows:a sensitivity of 100%,a specificity of 63.6%,the positive predictive value of 69.2%,the negative predictive value of 100%,and an accuracy of 80%for predicting stenosis ≥70%in the left anterior descending artery;a sensitivity of 56.2%,a specificity of 91.6%,the positive predictive value of 81.8%,the negative predictive value of 75.8%,and an accuracy of 77.5%for predicting stenosis ≥70%in the left circumflex artery;a sensitivity of 95.6%,a specificity of 47.0%,the positive predictive value of 70.9%,the negative predictive value of 88.0%,and an accuracy of 75.0%for predicting stenosis ≥70%in the right coronary artery;the overall sensitivity of 85.9%,the overall specificity of 69.8%,the overall positive predictive value of 72.0%,the overall negative predictive value of 84.6%,and the overall accuracy of 77.5%.Conclusion AFI can provide a sensitive,objective,non-invasive,and inexpensive examination method for the early clinical forecast of coronary artery stenosis.
