| Objective:Evaluate the diagnostic value of various combinations of non-invasive laboratory examinations of coronary
atherosclerotic heart disease (CHD), screening of the effective coronary heart disease diagnosis and exclusion of indicators, to initially determine
the optimal strategy for early diagnosis of coronary artery disease.Methods:Analyze a number of non-invasive ancillary test
results (including resting ECG, Holter, stress ECG, myocardial perfusion imaging load, 16 or 64-slice CT coronary angiography) in 6419
patients of coronary heart disease, the abnormality of coronary angiography (at least a major coronary artery or its major branches are 逸
50% diameter stenosis) as the gold standard, observing the combination of a variety of non-inva sive laboratory examination in the
diagnosis of coronary heart diseases in specificity, sensitivity, misdiagnosis rate and rate of missed diagnosis, positive predictive value
and negative predictive value.Results:ensitivity 56.02-87.43%, specificity: 36.13-87.61%, positive predictive value: 58.83-97.16% ,
negative predictive value: 30.21-73.36%, In non-invasive means, the sensitivity and negative predictive value was the highest in the
Holter monitoring combined with myocardial perfusion imaging group, specificity and positive predictive value was the highest. in the
Holter combined with coronary CT imaging group.Conclusion:Combination of auxiliary examination can be used as an important
method of non-invasive diagnosis and the evaluation of coronary heart disease, Holter can be considered as basic and important mean of
screening in coronary heart disease at all levels of hospital. |
