Abstract

Background: The aim of this paper is to analyze the role of the biomarkers Interleukin 6, Tumoral Necrosis Factor a, sCD40L, high sensitive Troponin T, high sensitive C-Reactive Protein and Galectin-3 in predicting super response (SR) to Cardiac Resynchronization Therapy (CRT), as they have not been studied in this field before.

Methods: Clinical, electrocardiographic and echocardiographic data was obtained preimplant and after one year. SR was defined as reduction in LVESV = 30% at one year follow-up. Blood samples were extracted preimplant. Multivariate logistic regression and ROC curves were performed.

Results: 50 patients were included, 23 (46%) were SR. Characteristics related to SR were: female (35 vs. 11%, p?=?0.04), suffering from less ischemic cardiomyopathy (13 vs. 63%, p?<?0.0001) and lateral (0 vs. 18%, p?=?0.03), inferior (4 vs. 33%, p?=?0.01) and posterior infarction (0 vs. 22%, p?=?0.01); absence of mitral regurgitation (47% vs. 22%, p?=?0.04), wider QRS width (157.7?±?22.9 vs. 140.8?±?19.2ms, p?=?0.01), higher concentrations of sCD40L (6.9?±?5.1 vs. 4.4?±?3.3 ng/mL, p?=?0.02), and left ventricular lead more frequent in lateral medial position (69 vs. 26%, p?=?0.002). QRS width, lateral medial position of the lead and absence of mitral regurgitation were independent predictors of SR. sCD40L showed a moderate direct correla-tion with SR (r?=?0.39, p?=?0.02) and with the reduction of LVESV (r?=?0.44, p?=?0.02).

Conclusions: sCD40L correlates significantly with SR to CRT. QRS width, absence of mitral regurgitation and lateral medial position of the lead are independent predictors of SR in this cohort.

Fundamento: Analizar los biomarcadores Interleuquina 6, factor de necrosis tumoral α, sCD40L, troponina T hipersensible, proteína C-reactiva hipersensible y galectina-3 en la predicción de súper-respuesta (SR) a la terapia de resincronización cardiaca (TRC), ya que no han sido valorados con anterioridad.

Material y métodos: Se recopilaron datos clínicos, electrocardiográficos y ecocardiográficos preimplante y al año. Se definió SR como disminución del VTSVI ≥ 30% al año de seguimiento. Las muestras sanguíneas fueron extraídas preimplante. Se realizó regresión logística multivariante y curvas ROC.

Resultados: Se incluyeron 50 pacientes, 23 (46%) fueron SR.Las características relacionadas con la SR fueron: ser mujer (35 vs. 11%, p = 0,04), sufrir menos cardiopatía isquémica (13 vs. 63%, p < 0,0001) e infarto lateral (0 vs. 18%, p = 0,03), inferior (4 vs. 33%, p = 0,01) y posterior (0 vs. 22%, p = 0,01); ausencia de insuficiencia mitral (47% vs. 22%, p = 0,04), mayor anchura del QRS (157,7 ± 22,9 vs. 140,8 ± 19,2 ms, p = 0,01), mayor concentración de sCD40L (6,9 ± 5,1 vs. 4,4 ± 3,3 ng/mL, p = 0,02), y electrodo ventricular izquierdo más frecuentemente en posición lateral media (69 vs. 26%, p = 0,002). El QRS, la posición lateral media del electrodo y la ausencia de insuficiencia mitral fueron predictores independientes de SR. sCD40L mostró una correlación moderada directa con SR (r = 0,39, p = 0,02) y con la disminución del VTSVI (r = 0,44, p = 0,02).

Conclusiones: sCD40L se correlaciona significativamente con SR a la TRC. El QRS, la ausencia de insuficiencia mitral y la posición lateral media del electrodo son predictores independientes de SR en esta cohorte.
