Comparison of measurement of left ventricular ejection fraction by Tc-99m sestamibi first-pass angiography with electron beam computed tomography in patients with anterior wall acute myocardial infarction

The goal of this study was to compare measurements of left ventricular (LV) ejection fraction (EF) by first-pass radionuclide angiography (“first-pass angiography”) using technetium-99m (Tc-99m) sestamibi with those by contrast-enhanced electron beam computed tomography (“electron beam tomography”)...

description The goal of this study was to compare measurements of left ventricular (LV) ejection fraction (EF) by first-pass radionuclide angiography (“first-pass angiography”) using technetium-99m (Tc-99m) sestamibi with those by contrast-enhanced electron beam computed tomography (“electron beam tomography”) as a reference technique in patients with an anterior wall acute myocardial infarction (AMI). Twenty-five patients with first Q-wave anterior wall AMI underwent paired electron beam tomographic and first-pass angiographic studies (mean, 1 day apart). Fourteen patients had 2 sets of measurements of the LVEF obtained by both methods (separated by at least 6 weeks), for a total of 39 paired measurements. LVEF by electron beam tomography was calculated from absolute systolic and diastolic LV chamber volumes. LV volumes by electron beam tomography were 199 ± 51 ml at end-diastole and 111 ± 42 ml at end-systole. Mean LVEF was 45 ± 11% by first-pass tomography and 46 ± 9% by electron beam tomography. The linear correlation coefficient between both methods was 0.82 (p
