Numerous criteria believed to define a positive response to cardiac resynchronization therapy (CRT) have been utilized in the literature. No study has investigated agreement amongst these response criteria. We hypothesized that the agreement between the various response criteria would be poor. A literature search was conducted with the keywords “cardiac resynchronization” and “response”. The 50 publications with the most citations were reviewed. After excluding editorials and reviews, seventeen different primary response criteria were identified from 26 relevant articles. The agreement amongst fifteen of these seventeen response criteria was assessed in 426 patients from the PROSPECT study using Cohen's κ coefficient (two response criteria were not calculable from PROSPECT data). The overall response rate ranged from 32-91% for the fifteen response criteria. Ninety-nine percent of patients showed a positive response by at least one of the fifteen criteria while 94% were classified as a non-responder by at least one criterion. Kappa values were calculated for all 105 possible comparisons amongst the fifteen response criteria and classified into standard ranges: poor agreement (κ≤0.4), moderate agreement (0.4<κ<0.75) and strong agreement (κ≥0.75). Seventy-five percent of the comparisons showed poor agreement, 21% showed moderate agreement and only 4% showed strong agreement. The 26 most cited publications on predicting response to CRT define response using 17 different criteria. Agreement between different methods to define response to CRT is poor 75% of the time and strong only 4% of the time, which severely limits the ability to generalize results over multiple studies.
