About

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.
