| description | Background and objective: Fluid overload is an important factor of morbidity and mortality in hemodialysis patients. Today correct determination of dry weight (DW) remains an important issue of hemodialysis practice. Within this context, it is subjected to new method searching. The objective of this study was to calculate estimated pulmonary capillary wedge pressure (ePCWP) with Tissue Doppler Imaging (TDI) in hemodialysis patients and to evaluate its correlation with the other volume markers and to evaluate whether it can be a new method for detection of DW. Materials and methods: Echocardiographic, hemodynamic, and biochemical volume markers of 41 hemodialysis patients were evaluated in the pre- and post-dialysis periods. Patients were divided into two groups based on ePCWP values (Group 1 ePCWP < 20 mmHg, Group 2 ePCWP > 20 mmHg). Results: In the pre-dialysis period; parameters related to volume load including ePCWP, systolic blood pressure, mean arterial pressure, pulse pressure, left atrial diameter, left atrial volume, E/é, ratio and E/Vp ratio were statistically significantly higher in Group2 compared to Group1. On the other hand, strong correlations were found between pre-dialysis ePCWP and systolic blood pressure, mean arterial pressure, pulse pressure, NT-ProBNP, left atrial diameter, E/é ratio and E/Vp ratio. Conclusions: Strong correlations found between ePCWP which was calculated with TDI and the other volume markers both in pre-dialysis and post-dialysis periods. These findings can provide a significant contribution to routine evaluating of DW in hemodialysis patients. From this aspect, the prediction of ePCWP with TDI can be a new practical and reproducible method for the determination of DW. Resumen: Antecedentes y objetivo: La hipervolemia es un factor importante de morbimortalidad en pacientes en hemodiálisis. Actualmente, la determinación correcta del peso seco (PS) sigue siendo un aspecto importante en la práctica de la hemodiálisis. Por este motivo se siguen buscando nuevos métodos. El objetivo de este estudio fue calcular la presión capilar pulmonar (PCPe) mediante ecografía Doppler tisular (EDT) en pacientes en hemodiálisis, con el fin de evaluar su correlación con los demás marcadores de volumen y valorar si podría ser un nuevo método para la determinación del PS. Materiales y métodos: Se evaluaron los marcadores de volumen ecocardiográficos, hemodinámicos y bioquímicos de 41 pacientes en hemodiálisis en los periodos previos y posteriores a la diálisis. Los pacientes se dividieron en 2 grupos en función de los valores de PCPe (PCPe del grupo 1 < 20 mmHg, PCPe del grupo 2 > 0 mmHg). Resultados: En el periodo previo a la diálisis, los parámetros relacionados con la carga de volumen, como la PCPe, la presión arterial sistólica, la presión arterial media, la presión diferencial, el diámetro auricular izquierdo, el volumen auricular izquierdo y los cocientes E/é y E/Vp fueron superiores de forma estadísticamente significativa en el grupo 2 en comparación con el grupo 1. Por otro lado, se observaron correlaciones importantes entre la PCPe previa a la diálisis y la presión arterial sistólica, la presión arterial media, la presión diferencial, el NT-proBNP, el diámetro auricular izquierdo y los cocientes E/é y E/Vp. Conclusiones: Se observaron correlaciones importantes entre la PCPe calculada mediante EDT y los demás marcadores de volumen, tanto en el periodo previo a la diálisis como en el posterior. Estos resultados pueden representar una contribución significativa a la evaluación ordinaria del PS en pacientes en hemodiálisis. Desde este punto de vista, la predicción de la PCPe mediante EDT puede ser un método práctico y reproducible para la determinación del PS. |
