Abstract

The long‐term relationship between fracture‐prone implantable cardioverter‐defibrillator (ICD) leads and poor prognosis remains unclear in Japanese patients. We conducted a retrospective review of the records of 445 patients who underwent implantation of advisory/Linox leads (Sprint Fidelis, 118; Riata, nine; Isoline, 10; Linox S/SD, 45) and non‐advisory leads (Endotak Reliance, 33; Durata, 199; Sprint non‐Fidelis, 31) between January 2005 and June 2012 at our hospital. The primary outcomes were all‐cause mortality and ICD lead failure. The secondary outcomes were cardiovascular mortality, heart failure (HF) hospitalization, and the composite outcome of cardiovascular mortality and HF hospitalization. During the follow‐up period (median, 8.6 [4.1–12.0] years), there were 152 deaths: 61 (34%) in patients with advisory/Linox leads and 91 (35%) in those with non‐advisory leads. There were 32 ICD lead failures: 27 (15%) in patients with advisory/Linox leads and five (2%) in those with non‐advisory leads. Multivariate analysis for ICD lead failure demonstrated that the advisory/Linox leads had a 6.65‐fold significantly greater risk of ICD lead failure than non‐advisory leads. Congenital heart disease (hazard ratio 2.51; 95% confidence interval 1.08–5.83; p= .03) could also independently predict ICD lead failure. Multivariate analysis for all‐cause mortality demonstrated no significant association between advisory/Linox leads and all‐cause mortality. Patients who have implanted fracture‐prone ICD leads should be carefully followed up for ICD lead failure. However, these patients have a long‐term survival rate comparable with that of patients with non‐advisory ICD leads in Japanese patients. Patients who were implanted with fracture‐prone ICD leads should be carefully followed up for ICD lead failure. However, such patients have comparable long‐term survival rates with those with non‐advisory ICD leads.

Abstract

Background: Despite the effectiveness of implantable cardioverter defibrillators (ICDs) in the prevention of sudden cardiac death, shock therapy causes patients to experience pain and psychological distress, which contradicts the purpose of palliative care. It is difficult to predict the time course for heart failure (HF) patients, unlike that for cancer patients. The aim of this study was to evaluate the deactivation status of ICD therapy in Japanese patients with end‐stage HF. Methods: We retrospectively studied 51 ICD patients who died due to worsening HF at Tokyo Women's Medical University Hospital from 2010 to 2019. The frequency of ICD therapy delivered before death and information about the discussion of deactivation and do not attempt resuscitation (DNAR) decisions were reviewed using medical charts. Results: Of 51 patients, 12 (24%) patients deactivated ICD therapy and seven patients underwent deactivation within 24 hours of a DNAR order. The median time from deactivation to death was 3 days (range, 0‐56). Of 39 patients with DNAR orders, 27 (69%) did not undergo deactivation. A relatively high proportion of patients (n = 14, 27%) experienced ICD shocks within 1 month of death. The frequency of electrical storms within 1 month of death was also high (n = 12, 24%). Conclusions: Our study showed that only one‐fourth of Japanese patients with end‐stage HF underwent deactivation of ICD therapy. A relatively high frequency of shock therapy was observed in the last month before death. [ABSTRACT FROM AUTHOR]

Abstract

Background In “real-world” practice, anticoagulant therapy is indicated for patients whose clinical profiles are not addressed in randomized clinical trials. We assessed the effectiveness and safety of dabigatran versus warfarin in “real-world” Japanese patients with non-valvular atrial fibrillation (NVAF). Methods Among 613 NVAF patients who initiated dabigatran or warfarin therapy during the period between 2011 and 2013, 362 patients were included in the study after propensity score adjustment. The median follow-up period was 1.3 years. The effectiveness and safety outcomes were thromboembolism and major bleeding, respectively. Results The propensity-matched hazard ratios of thromboembolism and major bleeding with dabigatran were 1.03 (95% CI: 0.12-8.04, p =0.971) and 0.15 (95% CI: 0.01–0.90, p =0.037), respectively. Conclusions The ability of dabigatran to prevent thromboembolism is comparable to that of warfarin; however, the major bleeding rate is lower with dabigatran in “real-world” NVAF patients.
