Fatores Biológicos e Superestimação da Fração de Ejeção do Ventrículo Esquerdo no Gated SPECT Biological Factors and Overestimation of Left Ventricular Ejection Fraction by Gated SPECT

Results: The following odds ratios were found (p 0.2). In the subgroup of 1002 patients, a statistically significant influence was found in overestimated LVEF values for the systolic diameter, gender and height variables. Conclusion: Although systolic diameter influences the overestimation of LVEF, the gender and height variables have an independent influence on LVEF overestimation by gated SPECT.
