Abstract:
Objective: To evaluate diagnostic value of three noninvasive examinations for coronary heart disease (CHD).Methods:A total of 500 subjects, who were suspected of CHD, first received diagnostic coronary angiography (CAG) and hospitalized in our department from May 2014 to May 2015, were selected.According to CAG results, they were divided into non-CHD control group (n=106), single vessel coronary disease group (n=199), double-vessel coronary disease group (n=95) and multi-vessel coronary disease group (n=100, ≥three vessel disease).Besides CAG, all subjects accomplished one of following examinations at least: (1) 24h dynamic ECG (Holter);(2) real-time three-dimensional echocardiography(RT-3DE);(3) radionuclide myocardial perfusion imaging (RMPI).Sensitivity, specificity and accuracy of these three examinations in diagnosing CHD were evaluated.Results: With CAG as the gold standard, compared with Holter and RT-3DE, there were significant rise in sensitivity(68.4%, 69.0% vs.92.9%), specificity (62.9%, 81.4% vs.88.5%) and accuracy (67.1%, 71.2% vs.91.9%) of RMPI (P<0.01 all), only specificity of RT-3DE was significantly higher than that of Holter, P=0.019.Conclusion:Noninvasive examination can be used as important method diagnosing CHD, which are important measures for noninvasive diagnosing and assessing CHD.Accuracy, sensitivity and specificity of RMPI are high, which is worth extending.
