Figure 1 Proportions of patients who underwent dobutamine stress real-time contrast echocardiography without inducible abnormalities (dark areas represent fixed abnormalities, white areas represent negative) (A) and with inducible abnormalities (dark areas represent fixed plus inducible abnormalities, white areas represent inducible abnormalities) (B) by analysis of wall motion abnormalities (WMA) and myocardial perfusion imaging (MPI). Myocardial perfusion imaging identified a higher proportion of patients with inducible abnormalities than WMA (32% vs. 17%; p < 0.01) and a lower proportion of patients without inducible abnormalities (68% vs. 83%; p < 0.01).

Figure 2 Distribution of the left ventricular walls in which the myocardial perfusion imaging was considered not feasible both at baseline and at peak stress. The lateral, anterior, and posterior walls were the most frequently considered as not feasible.
