Show moreOBJECTIVES In the third report of the European Registry for Patients with Mechanical Circulatory Support of the European Association for Cardio-Thoracic Surgery, outcomes of patients receiving mechanical circulatory support are reviewed in relation to implant era. METHODS Procedures in adult patients (January 2011-June 2020) were included. Patients from centres with <60% follow-ups completed were excluded. Outcomes were stratified into 3 eras (2011-2013, 2014-2017 and 2018-2020). Adverse event rates (AERs) were calculated and stratified into early phase (<3 months) and late phase (>3 months). Risk factors for death were explored using univariable Cox regression with a stepwise time-varying hazard ratio (3 months). RESULTS In total, 4834 procedures in 4486 individual patients (72 hospitals) were included, with a median follow-up of 1.1 (interquartile range: 0.3-2.6) years. The annual number of implants (range: 346-600) did not significantly change (P = 0.41). Both Interagency Registry for Mechanically Assisted Circulatory Support class (classes 4-7: 23, 25 and 33%; P < 0.001) and in-hospital deaths (18.5, 17.2 and 11.2; P < 0.001) decreased significantly between eras. Overall, mortality, transplants and the probability of weaning were 55, 25 and 2% at 5 years after the implant, respectively. Major infections were mainly noted early after the implant occurred (AER(3 months): 0.45). Bilirubin and creatinine levels were significant risk factors in the early phase but not in the late phase after the implant. CONCLUSIONS In its 10 years of existence, EUROMACS has become a point of reference enabling benchmarking and outcome monitoring. Patient characteristics and outcomes changed between implant eras. In addition, both occurrence of outcomes and risk factor weights are time dependent.As a registry of the European Association for Cardio-Thoracic Surgery, the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) offers a robust repository of clinical data on long-term mechanical circulatory support (MCS) from a large international community.

Show moreAims The implantable cardiac defibrillator/cardiac resynchronization therapy with defibrillator-based HeartLogic (TM) algorithm has recently been developed for early detection of impending decompensation in heart failure (HF) patients; but whether this novel algorithm can reduce HF hospitalizations has not been evaluated. We investigated if activation of the HeartLogic algorithm reduces the number of hospital admissions for decompensated HF in a 1 year post-activation period as compared with a 1 year pre-activation period.Methods and results Heart failure patients with an implantable cardiac defibrillator/cardiac resynchronization therapy with defibrillator with the ability to activate HeartLogic and willingness to have remote device monitoring were included in this multicentre non-blinded single-arm trial with historical comparison. After a HeartLogic alert, the presence of HF symptoms and signs was evaluated. If there were two or more symptoms and signs apart from the HeartLogic alert, lifestyle advices were given and/or medication was adjusted. After activation of the algorithm, patients were followed for 1 year. HF events occurring in the 1 year prior to activation and in the 1 year after activation were compared. Of the 74 eligible patients (67.2 +/- 10.3 years, 84% male), 68 patients completed the 1 year follow-up period. The total number of HF hospitalizations reduced from 27 in the pre-activation period to 7 in the post-activation period (P = 0.003). The number of patients hospitalized for HF declined from 21 to 7 (P = 0.005), and the hospitalization length of stay diminished from average 16 to 7 days (P = 0.079). Subgroup analysis showed similar results (P = 0.888) for patients receiving cardiac resynchronization therapy during the pre-activation period or not receiving cardiac resynchronization therapy, meaning that the effect of hospitalizations cannot solely be attributed to reverse remodelling. Subanalysis of a single-centre Belgian subpopulation showed important reductions in overall health economic costs (P = 0.025).Conclusion Activation of the HeartLogic algorithm enables remote monitoring of HF patients, coincides with a significant reduction in hospitalizations for decompensated HF, and results in health economic benefits.
