The Study Of The Diagnostic Value Of Strain Rate Imaging (SRI) Combined With Adenosine Stress For Coronary Artery Disease

Objective:To investigate the diagnostic value of strain rate imaging(SRI) combined with adenosine stress echocardiography for coronary artery disease(CAD).Methods:In 45 cases of suspected coronary artery diseases,Who were given the adenosine 140μg/(kg·min) intravenously for 6 minutes continuously,the SRI of 16 left ventricular segments was acquired in before test and 3 minutes and 6 minutes from the injection,and 5 minutes after injection respectively.Analyzing the change of the myocardial systolic strain rate,strain and velocity,and comparing them with the coronary angiography.Result:By the reduction of the myocardial systolic strain rate,strain and velocity in order to diagnose the coronary artery disease,The sensitivity was 77.27%and specificity of 89.47% without serious adverse reactions.Conclusions:The method of myocardial strain rate imaging(SRI) combined with adenosine stress echocardiography test for the diagnosis of the coronary heart disease is feasible.
