Left ventricular ejection fraction [LVEF] determination in post myocardial infarction patients. A comparison of gated blood pool [GBP] ventriculography and contrast ventriculography

ABSTRACT

To compare the efficacy of gated blood pool versus contrast ventriculography [Gold standard] for determination of ejection fraction in post myocardial infarction patients. Patients and Gated blood pool imaging [BPI] was performed by gated blood pool radionuclide ventriculography or MUGA in 30 patients within 48 hours after single plane [RAO-30] contrast ventriculography. Statistical analysis was done by student "t-test" [unpaired] and by Pearson's correlation co-efficient. Result: There was no significance difference in their mean ejection fraction [44.04 +/- 11.93 Vs 48.46 ' 12.78%, P = NS] and has statistically significant correlation [r=0.86, P=0.171] GBP ventriculography can therefore be utilized accurately for determination of ejection fraction for prognostic and diagnostic evaluation of post myocardial infarction patients
