Myocardial performance index suggests optimal XXXX during hemodialysis.

@entity1 @entity393 @entity65 @entity454
BACKGROUND: @entity1 on long-term maintenance hemodialysis (HD) are at high risk of developing @entity65 and suffering various @entity65 during HD. HYPOTHESIS: The purpose of this study was to evaluate the influence of changing loading conditions on the myocardial performance index (MPI) in @entity1 on long-term HD and to specify an optimal level of @entity393 during HD that would maintain stable global cardiac function. METHODS: The study consisted of 52 @entity1 with @entity454 ( @entity454 ), mean age 56  11.7 y, range: 25-80 y, on regular HD. For each @entity1 a complete echocardiographic-Doppler examination was performed before and after HD. Systolic and diastolic parameters of left ventricular function were measured, and the myocardial performance index (MPI) was calculated. RESULTS: The MPI was significantly prolonged after HD (0.47  0.15 before HD versus 0.59  0.16 after HD, p < 0.001). Mean change in body weight during HD was 2.1  0.86 kg. The MPI did not change significantly in @entity1 with intradialytic weight loss up to 1.75 kg. CONCLUSIONS: The MPI value seems to be independent of acute preload changes only when @entity393 is less than 1.75 kg. A 1.75-kg @entity393 during HD seems to be the optimal goal. In @entity454 @entity1 on HD, the MPI seems to be a good indicator of global left ventricular function and potentially a valuable aid in the effort to maintain optimal fluid balance.
