Measurements of myocardial contractile function at rest and during dobutamine stress test (mean±SEM) in each study arm at baseline and follow-up.The change from baseline to follow-up did not differ between study arms with regard to (A) left ventricular ejection fraction (p=0.18), (B) strain (p=0.10), (C) S′max (p=0.32) and (D) wall motion scoring (p=0.35).
