Key result
Two-dimensional echocardiography compares well with radionuclide ventriculography for assessing ejection fraction after acute myocardial infarction, with a mean difference of 0.4%.
Why the study?
Does two-dimensional echocardiography provide comparable left ventricular ejection fraction measurements to radionuclide ventriculography in patients following acute myocardial infarction?

Mean Difference: 0.4 (95% CI -11.4–12.2)
p-value: p=not significantly different from zero
Two-dimensional echocardiography is a reliable alternative to radionuclide ventriculography for assessing LVEF post-MI, avoiding radiation exposure.

Supports echocardiography as radiation-free LVEF option post-MI; leaves open confirmation in larger prospective studies.
Senior et al. (1994) conducted a cross-sectional in Acute myocardial infarction (n=49). Two-dimensional echocardiography vs. Radionuclide ventriculography was evaluated on Difference in left ventricular ejection fraction (%) (Mean difference 0.4, 95% CI -11.4 to 12.2, p=not significantly different from zero). Two-dimensional echocardiography compares well with radionuclide ventriculography for assessing ejection fraction after acute myocardial infarction, with a mean difference of 0.4%.
