Effect of Pharmacologic Stress Test Results on Outcomes in Obese versus Nonobese Subjects Referred for Stress Perfusion Echocardiography

Real-time contrast stress echocardiography (RTCSE) permits the simultaneous analysis of myocardial perfusion and wall motion during stress echocardiography, which has resulted in improved coronary artery disease detection. Although several studies have confirmed a protective effect of obesity in coronary artery disease, it is unclear whether this benefit is dependent on the functional significance of the disease. The objective of this study was to compare outcomes in obese versus nonobese subjects referred for pharmacologic RTCSE.
