N2 - The feasibility and diagnostic accuracy of transesophageal pacing stress echocardiography for detection of inducible myocardial ischemia were evaluated in 161 patients 80 years of age or older (mean 84 ± 3.9, range 80-97). The pacing time was 5.5 ± 2.5 minutes with a total test time of 37 ± 7 minutes. The mean achieved heart rate was 96 ± 7% (83%-121%) of maximum predicted with an average rate pressure product of 21,560 ± 5175 beats/min × mm Hg. There were minor adverse events in 8% of cases and no major complications occurred. Patient acceptance was high. When compared with myocardial single photon emission computed tomography, pacing stress echocardiography had a sensitivity of 89% and a specificity of 93% for the detection of myocardial ischemia, and 91% agreement (κ = 0.80, P < .001). We demonstrate that pacing stress echocardiography is safe and accurate for detection of myocardial ischemia and, thus, a reliable substitute to exercise and pharmacologic stress testing in octogenarians.
