Interpretive variability of @entity452 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 @entity1 population. We directly compared the interpretive reproducibility of DSE and stress SPECT in @entity1 undergoing both types of pharmacologic stress imaging. Before discharge, simultaneous DSE and SPECT was performed in 56 @entity1 early after a first @entity583 . Intra- and interobserver concordances were evaluated by exact agreement and kappa statistic. Intraclass coefficient of correlation was used to assess intra- and interobserver reproducibilities of segmental score analysis. Intraobserver agreement percentages in the identification of @entity1 with @entity63 were 98% for SPECT and 91% for DSE (p = NS) and kappa values were excellent (>0.80) for both techniques. Interobserver agreement was higher (p <0.01) for SPECT (96%) than for DSE (79%). Similarly, kappa value was excellent for SPECT (0.92) and only moderate for DSE (0.56). Finally, the intraclass coefficients of correlation for intra- and interobserver reproducibilities were higher for SPECT (0.98 and 0.97, respectively) than for DSE (0.80 and 0.71, respectively; p <0.001 for both). In conclusion, after uncomplicated @entity583 , stress SPECT imaging has a better interpretive reproducibility than DSE.
