Objetivo: Determinar diferencias en las impedancias basales registradas durante los procedimientos de denervación renal por radiofrecuencia de los pacientes sometidos a este procedimiento en la Fundación Cardioinfantil de Bogotá durante los años 2012 a 2015. Materiales y métodos: Estudio observacional, analítico de corte retrospectivo, donde se analizaron todas las impedancias basales medidas durante los procedimientos de denervación renal, buscando diferencias significativas entre los segmentos de las arterias intervenidas, estratificados en proximal, medio distal y superior, lateral, inferior u ostial. Con seguimiento a los pacientes a tres, seis y doce meses en cuanto a presión arterial de consultorio. Resultados: Se evaluaron 150 puntos de denervación renal exitosos, correspondientes a 23 arterias renales de 11 procedimientos. La mediana de edad fue 56 años. Al realizar un modelo de regresión lineal no se encontró ninguna diferencia estadísticamente significativa entre las impedancias de ninguno de los segmentos de las arterias ni sitios anatómicos. Se documentó disminución de presión arterial sistólica a tres meses, seis meses y doce meses de 14 mmHg (RIQ 10-33mmHg), 21 mmHg (RIQ 12-42mmHg) y 19 mmHg (RIQ 11-42 mmHg) respectivamente Objective: To determine differences in baseline impedances procedures recorded during renal radiofrequency denervation of patients undergoing this procedure in Bogota Fundación Cardioinfantil during the years 2012-2015. Materials and methods: observational, analytical retrospective, where all baseline impedance measurements were analyzed during procedures of renal denervation, looking for significant differences between segments of the operated arteries, stratified proximal, distal, middle and distal, and top, side, inferior and ostial. To follow patients for three, six and twelve months in terms of office blood pressure. Results: Successful 150 points, corresponding to 23 renal arteries 11 renal denervation procedures were evaluated. The median age was 56 years. When performing a linear regression model no statistically significant difference between the impedances of any of the segments of arteries or anatomic sites was not found. It decreases in systolic blood pressure three months, six months and twelve months of 14 mmHg (IQR 10-33mmHg), 21 mmHg (IQR 12-42mmHg) and 19 mmHg (IQR 11-42 mmHg) was documented respectively. |
