  ABSTRACT: Background: The predictive value of Dobutamine Stress Echocardiography (DSE) in the obese African American patient population is not well known. Methods: We conducted a retrospective study of 555 African American patients between 1/1/2001-12/31/2001. DSE responses were classified into normal, ischemia, scar, or scar +/? ischemia. End-points utilized were all cause death (ACD) and major adverse cardiac events (MACE). Results: There were a total of 409 obese patients and 146 non-obese patients. By multi-variate analysis only the scar group in the obese population predicted ACD (p = 0.003) and combined MACE (p = 0.014). Kaplan Meir analysis demonstrated that only the scar group was associated with decrease in freedom from all cause death (p
