[Assessment of the ejection fraction in ischemic cardiopathy with two-dimensional echocardiography. Validity and limits of the method].

: In this study the authors compare the Ejection Fraction (EF) as determined by the Single Plane Ellipse Echocardiographic method versus the Ventriculographic EF. The authors emphasize the validity of the two-dimensional echocardiography to assess left ventricular EF in order to improve the clinical and pharmacologic management of the patients with the cardiac ischaemic disease.
