Comparative analysis of echocardiography, multispiral computed tomography, myocardial perfusion scintigraphy in left ventricular mass evaluation

Abstract

Aim. To perform a comparative analysis of multispiral computed tomography, echocardiography and myocardial perfusion scintigraphy in the evaluation of left ventricular mass. Methods. The study included 44 patients (15 female, 29 male) aged of 21 to 73 years (mean age was 55±11 years). Left ventricular mass was assessed by noninvasive multispiral computed tomography coronary angiography using the 64-slice «Aquillon 64» (Toshiba, Japan) scanner. Echocardiographic evaluation was performed on the «Vivid-7» (GE, USA) ultrasound system. Scintigraphic analysis of left ventricular mass was performed on the single-detector gamma camera «Millenium-MPR» (GE, USA) using the «4-D MSPECT» (University of Michigan Medical Center) software. Results. A comparative analysis of left ventricular mass showed that the differences in median values were statistically significant between all the methods presented. The differences in left ventricular mass calculated using the Bland-Altman method were as follows: between multispiral computed tomography and echocardiography -32±41 gr, between multispiral computed tomography and myocardial perfusion scintigraphy «4-D MSPECT» 34±48 gr. Conclusion. Multispiral computed tomography, echocardiography, myocardial perfusion scintigraphy assess left ventricular mass differently, with myocardial perfusion scintigraphy giving the lowest and echocardiography giving the highest mass. Results gained at multispiral computed tomography lies in between the myocardial perfusion scintigraphy and echocardiography.
