BACKGROUND To estimate the prognostic value of submaximal negative dobutamine stress echocardiography (NDSE) on major cardiac events. METHODS AND RESULTS Patients with NDSE were analyzed in 2 cohorts based on predicted maximal heart rate (PMHR) (< 85% or > or = 85% PMHR) and were assessed for major adverse cardiac events over 3 years. Of 756 patients with NDSE, 415 achieved > or = 85% PMHR. Both groups had comparable ejection fractions (EF) > 50% (80.6% vs. 81.9%, p = 0.66). The NsubDSE group… CONTINUE READING
