[Evaluation of ejection fraction and end-diastolic volume using one-dimensional and two-dimensional echocardiography]

A group of 30 healthy persons and 120 coronary patients were investigated by one and two-dimensional echocardiography and digital subtraction angiography. End-diastolic volume and ejection fraction were estimated. Patients with coronary disease had greater volumes than healthy persons and smaller ejection fraction as well. The correlation of the given values showed that data gathered by two-dimensional echocardiography have greater coefficient in comparison to digital subtraction angiography (end-diastolic volume index r = 0.86, ejectional fraction r = 0.88, p < 0.01) than the same data estimated by one-dimensional technique. Two-dimensional echocardiography is a reliable noninvasive method for evaluation of these significant indicators of left ventricle function.
