BACKGROUND: Tissue Doppler imaging (TDI) is used to improve risk stratification in @entity1 with @entity712 ( @entity712 ). So far, few studies have used this method to investigate the characteristics of subjects with @entity712 and @entity14620 ( @entity14620 ). The aim of this study was therefore to evaluate whether TDI assessment may predict the presence of @entity14620 in @entity1 with @entity712 . MATERIALS AND METHODS: A total of 41 consecutive @entity1 with @entity712 enrolled in the Daunia @entity712 Registry underwent echocardiography assessment and nocturnal polygraphy to evaluate the presence of @entity387 and @entity14620 . Conventional echocardiography and TDI parameters were calculated. We have also quantified by TDI a combined index (EAS index) of diastolic and systolic performance: E'/(A' * S'). RESULTS: Subjects with evidence of @entity14620 (N = 8) were characterized by lower values of A' (5  03    2  64 vs. 7  88    2  64 cm/s, P < 0  01). A' and EAS index values were related to Cheyne-Stokes episode rates (r = -0  49 and 0  52, P < 0  05 and <0  01 respectively), EAS index values also with the number of episodes of central @entity386 (r = 0  39, P < 0  05). A' values predicted the presence of @entity14620 at poly-somnography examination with an OR 0  62 (95% CI 0  40-0  96, P < 0  05) even after correction for age and gender. CONCLUSIONS: Tissue Doppler imaging values (A') are associated with the presence of @entity387 at nocturnal polygraphy.
