Abstract

Interpretive variability of dobutamine stress echocardiography (DSE) and stress single-photon emission computed tomography (SPECT) has been previously investigated. However, no study has directly compared the variability of these techniques in the same patient population. We directly compared the interpretive reproducibility of DSE and stress SPECT in patients undergoing both types of pharmacologic stress imaging. Before discharge, simultaneous DSE and SPECT was performed in 56 patients early after a first acute myocardial infarction. Intra- and interobserver concordances were evaluated by exact agreement and κ statistic. Intraclass coefficient of correlation was used to assess intra- and interobserver reproducibilities of segmental score analysis. Intraobserver agreement percentages in the identification of patients with ischemia were 98% for SPECT and 91% for DSE (p = NS) and κ values were excellent (>0.80) for both techniques. Interobserver agreement was higher (p
