Abstract:
Objective To evaluate left ventricular regional volume and function of the patients with myocardial infarction by real-time three-dimensional echocardiography.Methods The study consisted of 24 normal subjects and 27 patients with myocardial infarction.Three-dimensional image data were acquired and were analysed offline.Regional volume curves and regional ejection fraction curves were derived.Regional diastolic volumes,regional systolic volumes and regional ejection fractions were compared respectively between two groups.Results The normal regional volume curves and regional ejection fraction curves were regular parabola.The regional volume increased and ejection fraction decreased in the zones with infarction,and the amplitudes of the regional volume curves and the regional ejection fraction curves decreased.Conclusions Real-time three-dimensional echocardiography can evaluate left ventricular regional volume and regional function objectively.
