A novel method to risk stratify patients undergoing exercise stress echocardiography using a set of combined criteria.

Background and Purposes A novel method using quantitative long-axis function and tissue Doppler in addition to wall motion analysis in exercise stress echocardiography was evaluated. We hypothesized that the novel criteria added additional accuracy in stress echocardiography. Methods Patients with chest pain and at low-to-intermediate risk for obstructive coronary artery disease (CAD) were retrospectively studied.
