Quantitative assessment of global and regional left ventricular function in patients with acute myocardial infarction by real-time three-dimensional echocardiography / 中华超声影像学杂志

ABSTRACT

Objective To probe into clinical value of real-time three-dimensional echocardiography (RT-3DE) in evaluating global and regional left ventricular function in patients with acute inferior, posterior and lateral myocardial infarction(MI).Methods The study consisted of 41 normal subjects and 23 patients with acute MI.RT-3DE was performed and three-dimensional image data was analyzed offline with software.A series of global and regional left ventricular volume curves were plotted.Regional and global diastolic volumes, regional and global systolic volumes, regional and global ejection fractions, regional stroke volume to global diastolic volume were compared respectively between control group and MI group.Results By contrast with control group, global left ventricle function and regional left ventricle function in the zones with infarction and part of the zones close to infarction had significant difference( P＜0.05),however,no effective statistic change was found in the most of the distal zones of infarction( P＞0.05).Conclusions RT-3DE can accurately evaluate measurement the left ventricular global and regional function in patients with acute MI.
