Figure 6 Survival Curves of Patients With Suspected CHD Undergoing DSE and TDI

Patients with an average peak basal systolic velocity (Av Sm) of >6 cm/s were associated with a higher mortality than those Av Sm 6 cm/s. Reprinted with permission from Marwick et al. (13). CHD = coronary heart disease; DSE = dobutamine stress echocardiography; TDI = tissue Doppler imaging.
