[Assessment of left ventricular function by midwall fractional shortening in hemodialysis XXXX ].

@entity1 @entity296 @entity308 @entity101 @entity3207
OBJECTIVES: @entity3207 ( @entity3207 ) is a useful index to evaluate left @entity296 in @entity1 with essential @entity101 . The study investigated the prevalence and characterization of low @entity3207 in hemodialysis @entity1 . METHODS: @entity3207 was calculated from M-mode echocardiograms in 67 @entity1 (34 males, 33 females) receiving maintenance hemodialysis in whom fractional shortening was normal. Plasma levels of atrial and brain natriuretic peptides were also measured in these @entity1 before and after hemodialysis. @entity3207 was evaluated by stress-corrected @entity3207 (ratio of observed to predicted @entity3207 ). The relationship of @entity3207 to circumferential end-systolic stress in 122 healthy subjects was used to calculate the predicted @entity3207 . RESULTS: Stress-corrected @entity3207 was @entity308 in 18 of the 67 @entity1 (26.9%). In the low @entity3207 group, duration of @entity101 was significantly longer (p < 0.05), wall thickness was significantly greater (p < 0.001), left ventricular dimension was significantly smaller (p < 0.0001), and relative wall thickness was significantly greater (p < 0.0001) than in the normal @entity3207 group. Reduction of brain natriuretic peptide level by hemodialysis in the low @entity3207 group was significantly higher (p < 0.05) than in the normal @entity3207 group. CONCLUSIONS: Depression of stress-corrected @entity3207 may be common in hemodialysis @entity1 . Long duration of @entity101 and concentric geometry of the left ventricle occur in @entity1 with low @entity3207 .
