RESUMO
INTRODUCTION AND OBJECTIVES: HeartLogic is a multiparametric algorithm incorporated into implantable cardioverter-defibrillators (ICD). The associated alerts predict impending heart failure (HF) decompensations. Our objective was to analyze the association between alerts and clinical events and to describe the implementation of a protocol for remote management in a multicenter registry. METHODS: We evaluated study phase 1 (the investigators were blinded to the alert state) and phases 2 and 3 (after HeartLogic activation, managed as per local practice and with a standardized protocol, respectively). RESULTS: We included 288 patients from 15 centers. In phase 1, the median observation period was 10 months and there were 73 alerts (0.72 alerts/patient-y), with 8 hospitalizations and 2 emergency room admissions for HF (0.10 events/patient-y). There were no HF hospitalizations outside the alert period. In the active phases, the median follow-up was 16 (95%CI, 15-22) months and there were 277 alerts (0.89 alerts/patient-y); 33 were associated with HF hospitalizations or HF death (n=6), 46 with minor decompensations, and 78 with other events. The unexplained alert rate was 0.39 alerts/patient-y. Outside the alert state, there was only 1 HF hospitalization and 1 minor HF decompensation. Most alerts (82% in phase 2 and 81% in phase 3; P=.861) were remotely managed. The median NT-proBNP value was higher within than outside the alert state (7378 vs 1210 pg/mL; P <.001). CONCLUSIONS: The HeartLogic index was frequently associated with HF-related events and other clinically relevant situations, with a low rate of unexplained events. A standardized protocol allowed alerts to be safely and remotely detected and appropriate action to be taken on them.

Se presentan las conclusiones consensuadas de un panel de arritmólogos, convocados por la Sociedad Española de Cardiología, acerca del enfoque terapéutico de las arritmias cardíacas. El manuscrito se ha dividido en 7 secciones, que representan áreas de afinidad en cuanto a terapéutica: 1. Taquicardias supraventriculares no asociadas al síndrome de Wolff-Parkinson-White.2. Síndromes de preexcitación.3. Flúter auricular.4. Fibrilación auricular.5. Arritmias ventriculares no sostenidas.6. Taquicardias ventriculares sostenidas (en ausencia de síndrome de parada cardíaca).7. Síndrome de parada cardíaca por taquiarritmia ventricular. En cada una de las secciones se emiten recomendaciones en cuanto a las distintas opciones terapéuticas, farmacológicas y no farmacológicas, así como en cuanto a los subgrupos de pacientes subsidiarios de cada una de ellas (AU)
