Dobutamine echo viability was associated with post-PTCA LV recovery; supports predictive value but leaves open impact on revascularization decisions.
Does myocardial viability detected by dobutamine echocardiography predict long-term improvement in LV function after PTCA in patients with chronic coronary artery disease and regional LV dysfunction?
Viable myocardium detected by dobutamine echocardiography predicts long-term improvement in regional and global LV function after PTCA, though patients with persistent low LVEF remain at risk for adverse cardiac events.
