Key result
2D echocardiographic LVEF strongly correlated with ventriculography (r = 0.95, P < 0.001), and global longitudinal strain showed significant correlation with Biplane Simpson LVEF (r = -0.84, P < 0.001).
Why the study?

Population
45 patients recruited from coronary angiography candidates
Comparison

Strong correlations support echocardiographic LVEF as potential alternative to ventriculography; leaves open prospective outcome validation before practice change.

Effect estimate: r = 0.95
p-value: p=< 0.001
2D echocardiography and GLS show strong correlation and agreement with invasive left ventriculography for assessing left ventricular ejection fraction, with strain analysis offering reliable quantitative assessment.
Poorzand et al. (2014) conducted a cross-sectional in Coronary artery disease (angiography candidates) (n=45). 2D echocardiography and global longitudinal strain (GLS) vs. Left ventriculography was evaluated on Correlation between echocardiographic LVEF and angiographic LVEF (r = 0.95, p=< 0.001). 2D echocardiographic LVEF strongly correlated with ventriculography (r = 0.95, P < 0.001), and global longitudinal strain showed significant correlation with Biplane Simpson LVEF (r = -0.84, P < 0.001).
