Quantitative analysis of myocardia perfusion by real time myocardial contrast echocardiography in patients with coronary heart disease
摘要
Abstract
Objective To evaluate the clinical value of quantitative analysis of real time myocardial contrast echocardiography (RTMCE) in myocardial blood flow. Methods Twenty patients with left anterior descending artery stenosis > 75% (observed group) and 20 healthy healthy controls( control group )were chosen to experience the RTMCE examination, and ultrasound echocardiography was used to obtain parameters such as peak value of contrast medium (A), myocardial blood flow velocity(β), myocardial blood flow ( MBF), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD) , ejection fraction (EF), maximum early peak filling velocity (Emax), maximum late peak filling velocity ( Amax), Emax/Amax. The myocardial perfusion and cardiac function in the two groups were compared. Results In comparison with the control group, β and MBF in the observed group was found significantly lower (both P<0.01), and no significant difference was found in LVEDD, LVSED, EF, Emax, Amax, Emax/Amax. Conclusions Patients with coronary heart disease have slowly flowing blood and nu'crocirculation injury; RTMCE can evaluate perfusion defect in ischemic myocardium quantitatively .关键词
