Brief Summary

For a long time, it has been hoped that doctors could screen and diagnosis of coronary heart disease through non-invasive imaging techniques, so as to maximize the benefit/risk ratio of patients. This trial is to explore the screening and diagnostic value of three-dimensional speckle tracking technology for coronary heart disease, and the evaluation value of 3D speckle track image(3D-STI) technology for cardiac function improvement after coronary intervention, and to seek reliable, accurate and quantifiable non-invasive imaging examination for the diagnosis, follow-up and prognosis of coronary heart disease. In this study, coronary angiography is taken as the "gold standard", and 3d-STI echocardiography technology is proposed to combine with clinical characteristics of subjects for joint diagnosis, so as to evaluate the value of 3d-sti technology in the diagnosis of coronary heart disease. Patients were followed up with echocardiography after interventional treatment to explore the feasibility of 3D-STI technology in evaluating cardiac function improvement.

Outcome Measures

Primary Outcomes (1)

  • Left ventricular myocardial viability

    By measuring the strain and time to peak, the left ventricular myocardial viability was finally evaluated. Left ventricular local ventricular viable myocardium was quantitatively analyzed in patients .Aimed to detect the myocardial ischaemia and viability. The data of strain and time to peak were measured using the three-dimensional speckle tracking model. In apical four-chamber view, make sure the endocardium, mitral valve ring and apex imaging is clear, mark the left and right mitral valve ring and apex spot . After automatic ultrasonic echo spot tracked, software can delineate endocardial curve, and automaticaly calculate the left ventricular myocardial segments strain and time to peak. The strain peaks of each segment (including 16 segments) of the myocardium of the left ventricle included four strain peaks: RS, CS, LS and AS

    half an hour

Secondary Outcomes (1)

  • The value of 3D-STI technology on the improvement of left ventricular myocardial function

    half a year

Study Arms (1)

coronary artery disease

Patients who were diagnosed with coronary heart disease at admission and planned to undergo coronary angiography

Diagnostic Test: 3D-speckle tracking imaging

Interventions

The strain peak value and strain peaking time of each segment (including 16 segments) of the left ventricular myocardium can be obtained by 3d-sti technology.

Sampling MethodProbability Sample
Study Population

According to reference, the area under the ROC curve of 3d-STI strain peak and strain peaking time for the diagnosis of coronary heart disease is about 0.65.In this study, it is expected that the combined diagnosis model can increase the area under the ROC curve to the level of 0.85, and the standard deviation of the area under the ROC curve is estimated to be 0.5. In order to get 85% assurance, we plan to include 827 subjects.

You may qualify if:

  • patients diagnosed with coronary heart disease
