Key result
Intravenous contrast during dobutamine stress echocardiography significantly improved left ventricular segment visualization at peak stress compared to no contrast (98.9% vs 89.3%; p<0.00001).
Why the study?
Does the use of intravenous contrast during dobutamine stress echocardiography improve visualization and interpretability of LV segments in patients with class III obesity?

Carlino et al. (2021) conducted a cohort in Class III obesity (n=128). Intravenous contrast during dobutamine stress echocardiography vs. Dobutamine stress echocardiography without intravenous contrast was evaluated on Well-visualized and interpretable left ventricular segments at peak stress (p=< 0.00001). Intravenous contrast during dobutamine stress echocardiography significantly improved left ventricular segment visualization at peak stress compared to no contrast (98.9% vs 89.3%; p<0.00001).
