ABSTRACT
INTRODUCTION AND OBJECTIVES: The multiparametric implantable cardioverter-defibrillator HeartLogic index has proven to be a sensitive and timely predictor of impending heart failure (HF) decompensation. We evaluated the impact of a standardized follow-up protocol implemented by nursing staff and based on remote management of alerts. METHODS: The algorithm was activated in HF patients at 19 Spanish centers. Transmitted data were analyzed remotely, and patients were contacted by telephone if alerts were issued. Clinical actions were implemented remotely or through outpatient visits. The primary endpoint consisted of HF hospitalizations or death. Secondary endpoints were HF outpatient visits. We compared the 12-month periods before and after the adoption of the protocol. RESULTS: We analyzed 392 patients (aged 69±10 years, 76% male, 50% ischemic cardiomyopathy) with implantable cardioverter-defibrillators (20%) or cardiac resynchronization therapy defibrillators (80%). The primary endpoint occurred 151 times in 86 (22%) patients during the 12 months before the adoption of the protocol, and 69 times in 45 (11%) patients (P<.001) during the 12 months after its adoption. The mean number of hospitalizations per patient was 0.39±0.89 pre- and 0.18±0.57 postadoption (P<.001). There were 185 outpatient visits for HF in 96 (24%) patients before adoption and 64 in 48 (12%) patients after adoption (P<.001). The mean number of visits per patient was 0.47±1.11 pre- and 0.16±0.51 postadoption (P<.001). CONCLUSIONS: A standardized follow-up protocol based on remote management of HeartLogic alerts enabled effective remote management of HF patients. After its adoption, we observed a significant reduction in HF hospitalizations and outpatient visits.

OBJECTIVE: The recommendations for complete lead extraction because of local complications at the site of implantable devices have changed in the last 10 years. We analyze the outcome of patients who required an intervention because of a local complication between 2002 and 2010, in our Hospital. METHODS: We retrospectively studied 83 patients with a local complication that was classified according to skin integrity: 1. Integrity, and 2. Open skin. We analyzed the type of intervention: 1. Conservative approach, 2. Incomplete extraction, 3. Complete extraction. The endpoints were the needing a later intervention and a complete removal during follow up. RESULTS: The group of patients with complete system extraction showed a lower rate of re-intervention during an average follow up of 1000 days, when compared to other two groups (6.7% vs. 57.7 and 43.8%, P<.01). Incomplete extraction and conservative approach had a similar outcome, needing a complete extraction 25% and 37.5%, respectively. The skin integrity did not seem to be relevant for outcome in these two groups. An 8.4% incidence of endocarditis was observed; all of them had a previous history of incomplete extraction or conservative approach. CONCLUSIONS: Local complications treated with either a conservative approach or incomplete extraction are associated with a high rate of re-interventions, regardless of skin integrity, frequently needing final complete extraction and are associated to endocarditis.

Objetivo: Las recomendaciones para la extracción completa de la bolsa de dispositivos implantables por problemas locales han cambiado. Analizamos la evolución entre 2002 y 2010 de los pacientes que requirieron una intervención por una complicación local en nuestro centro. Métodos: Ochenta y tres pacientes tuvieron un problema local de la bolsa que se clasificó según integridad de la piel: 1. Íntegra y 2. Abierta, y el tipo de intervención realizada: 1. Conservadora, 2. Extracción parcial y 3. Extracción completa. El objetivo primario fue la necesidad de reintervención posterior y la de extracción total durante el seguimiento. Resultados: El grupo de pacientes con extracción completa presentó una menor tasa de reintervención durante el seguimiento medio de 1,000 días comparado con los otros 2 grupos (6.7 vs. 57.7 y 43.8%, p < 0.01). La extracción parcial y la actitud conservadora mostraron una evolución parecida con una tasa de extracción completa final del 25% y del 37.5%. Se observó una incidencia de endocarditis del 8.4%; todos con antecedente de extracción parcial o actitud conservadora. Conclusiones: Las complicaciones de la bolsa, independientemente de la integridad de la piel, tratadas conservadoramente o con extracción parcial se asocian a alta tasa de reintervenciones, necesidad de extracción completa y evolución a endocarditis.
