Insights

Cardiac implantable electronic device (CIED) patients often have chronic kidney disease (CKD). One-third of patients needing CIED removal have advanced CKD, impacting dialysis access and infection risk.

Area of Science:

  • Nephrology
  • Cardiology
  • Medical Devices

Background:

  • Cardiac implantable electronic devices (CIEDs) can lead to central venous stenosis and infection.
  • These complications are particularly concerning for patients with chronic kidney disease (CKD).
  • CKD patients require functional central veins for dialysis access and have increased CIED infection risk.

Purpose of the Study:

  • To investigate the prevalence and severity of chronic kidney disease (CKD) in patients with cardiac implantable electronic devices (CIEDs).

Main Methods:

  • Retrospective analysis of 503 patients undergoing CIED removal between 2001 and 2011.
  • Patients were categorized into CKD stages I-V using National Kidney Foundation-Dialysis Outcomes Quality Initiative guidelines.

Main Results:

  • 90% of patients had CKD; 32.7% had advanced CKD (Stage III B, IV, or V).
  • Patients undergoing CIED removal frequently have comorbidities like hypertension, diabetes, coronary artery disease, and congestive heart failure.
  • A significant portion of CIED patients exhibit advanced renal failure.

Conclusions:

  • One-third of patients requiring CIED removal present with advanced chronic kidney disease.
  • This finding highlights the critical interplay between CIEDs, CKD, and potential complications like central venous stenosis and infection.

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of fluid...
Chronic Kidney Disease I: Introduction01:25

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...
