عنوان انگلیسی Comparison of Left Ventricular Ejection Fraction Measurements by Echocardiography and Contrast Ventriculography: A Study on a Large Hospitalized Population
چکیده انگلیسی مقاله Background: The evaluation of the left ventricular ejection fraction (LVEF) is important for predictingmortality and identifying high-risk patients. We aimed to identify factors affecting the variationin the LVEF measurement via echocardiography and contrast left ventriculography (CVG).Methods: A total of 4422 patients (mean age=59.0±10.52 y, range=22–88) who underwentechocardiography and CVG within the same hospitalization period (0- to 14-day intervals) wereincluded. Data were obtained from the Echocardiography Data Bank and the CoronaryAngiography Data Bank in Tehran Heart Center.Results: The correlation between the estimation of the EF by echocardiography and CVG was good(r=0.716); however, there was no point-by-point agreement. In 21.5% of the patients,echocardiography and CVG estimated the EF equally, and a difference greater than 20% wasfound in 1.8% of the patients. The differences between the 2 measurements were remarkableeither in the patients with EFs greater than 50% or in those with EFs of 50% or less by CVG(59.71±3.72 by CVG vs 55.96±7.57% by echocardiography in EFs>50% and 40.69±8.96 byCVG vs 43.90±10.71% by echocardiography in EFs≤50%). By linear regression analysis, thepresence of pathologic Q wave, atrial fibrillation and left bundle branch block, moderate andsevere mitral regurgitation, increased LV size, and increased interventricular septal diameterresulted in a higher EF value via CVG, whereas in those with EFs of 50% or less, the EF byechocardiography was higher. No effect of time gap between the measurements was found.Conclusions: According to our study, the EF measurements obtained by echocardiography and CVGvaried on an individual basis. The level of the EF was the most important factor correlating withthe difference between the measurements by the methods.
