Myocardial viability independently influences left ventricular diastolic function in the early phase after XXXX .

@entity1 @entity296 @entity452 @entity39 @entity583
BACKGROUND: After @entity583 , a broad range of left ventricular (LV) end-diastolic pressure (LVEDP) is expected because of chamber remodeling. However, intrinsic characteristics of the infarcted tissue ( @entity39 or viability) may also play a role. We aimed to evaluate whether @entity296 ( @entity296 ) has an influence on LVEDP. METHODS: One hundred twenty-three consecutive @entity1 with @entity583 underwent low-dose @entity452 echocardiography (5-10 microg/kg/min) to assess @entity296 . @entity296 was quantitatively evaluated by the variation of Delta wall motion score index. @entity1 underwent left heart catheterization with recording of LVEDP and a complete echocardiographic examination with measurement of LV volumes, ejection fraction, and mass. RESULTS: The overall population (81% male; mean age 58 +/- 10 years) was divided into 2 groups according to the presence (group 1; 66 @entity1 ) or absence (group 2; 57 @entity1 ) of @entity296 . LVEDP was higher in @entity1 without @entity296 (16 +/- 8 vs 20 +/- 7 mm Hg; P =.02). The multivariate analysis showed that Delta wall motion score index correlated with LVEDP (P =.01) independent of wall motion score index and LV end-systolic volume. CONCLUSIONS: After @entity583 , LVEDP shows wide variability and is independently associated with @entity296 .
