Key result
Three-dimensional speckle-tracking echocardiography parameters (LVEF and strain) were significantly correlated with exercise capacity (peak VO2 and VE/VCO2 slope) in patients with heart failure.
Why the study?
Are left ventricular ejection fraction and strain derived by three-dimensional echocardiography associated with exercise capacity in patients with heart failure?
Cross-Sectional (n=80)
Are left ventricular ejection fraction and strain derived by three-dimensional echocardiography associated with exercise capacity in patients with heart failure?
Left ventricular ejection fraction and strain derived by 3D speckle-tracking echocardiography correlate significantly with objective measures of exercise capacity in patients with ischemic heart failure.

3D speckle-tracking parameters were associated with exercise capacity in HF; leaves open incremental prognostic value and requires prospective validation.
Pavlovic-Kleut et al. (2017) conducted a cross-sectional in Heart failure with reduced left ventricular ejection fraction (n=80). Three-dimensional speckle-tracking echocardiography (3D-STE) was evaluated on Relationship between exercise capacity parameters (peak VO2 and VE/VCO2) and 3D-STE imaging of LV function. Three-dimensional speckle-tracking echocardiography parameters (LVEF and strain) were significantly correlated with exercise capacity (peak VO2 and VE/VCO2 slope) in patients with heart failure.
