Insights

Secondary prevention implantable cardioverter-defibrillator (ICD) use is significantly lower in hemodialysis patients in Japan. Practice patterns showed consistent implantation rates across regions, with increasing subcutaneous-ICD use.

Area of Science:

  • Cardiology
  • Nephrology
  • Medical Device Technology

Background:

  • Secondary prevention implantable cardioverter-defibrillator (ICD) implantation in hemodialysis (HD) patients in Japan is not well understood.
  • Characterizing practice patterns and factors influencing ICD use in HD patients surviving cardiac arrest due to ventricular arrhythmias is crucial.

Purpose of the Study:

  • To characterize the clinical implementation of secondary prevention ICDs in Japanese hemodialysis patients.
  • To identify factors associated with ICD implantation in this population.
  • To analyze trends in device selection and variations in utilization.

Main Methods:

  • Nationwide analysis of the JROAD-DPC database (2012-2020).
  • Inclusion of cardiac arrest survivors with ventricular arrhythmias and no prior ICD.
  • Assessment of patient factors, temporal trends, and institutional/geographical variations in ICD implantation among HD patients.

Main Results:

  • HD patients had significantly lower ICD implantation rates (27%) compared to non-HD patients (44%).
  • Hemodialysis treatment was an independent negative predictor of ICD implantation (OR 0.42).
  • Subcutaneous-ICD use among HD patients increased from 13% to 32% (2016-2019).

Conclusions:

  • Significantly lower secondary prevention ICD use in HD patients compared to non-HD patients was observed.
  • ICD implantation patterns were consistent across Japanese healthcare institutions and regions.
  • Findings highlight the need for consensus development and prospective studies for optimal ICD selection in HD patients.

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Hemodialysis III: Nursing Management

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...
