We hypothesize that the accuracy of ASE categorization of early LVDD is affected by knowledge of whether CAD history is present.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We studied 34 patients (age 62\u00a0\u00b1\u00a07\u00a0years) with NYHA class I to II symptoms and with transthoracic echocardiography without findings suggesting myocardial disease (all with preserved LV ejection fraction), who underwent cardiac catheterization with high\u2010fidelity LV pressure measurement. Echocardiographic images were evaluated for LVDD using ASE algorithm without and with knowledge of CAD history and angiography findings. CAD was considered as having DD for the algorithm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>CAD was identified in 22 patients at catheterization (65%). Using ASE guidelines without including history of CAD or angiographic results, 29 patients were DD\u2212, 3 were DD+ (all grade II), and 2 were indeterminate. Inclusion of CAD history recategorized 59% (n\u00a0=\u00a020) patients to DD+ (all grade I) from DD\u2212 (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.0001). Nineteen of the recategorized patients (95%) had increased isovolumetric relaxation time (IVRT).
