Insights

Cardiac resynchronization therapy (CRT) improves kidney and heart function in patients with chronic kidney disease (CKD). Further research is needed to confirm its effects on mortality in this population.

Area of Science:

  • Cardiology
  • Nephrology
  • Medical Devices

Background:

  • Cardiac resynchronization therapy (CRT) offers benefits for heart failure patients.
  • This review focuses on CRT's impact on patients with chronic kidney disease (CKD), defined as estimated glomerular filtration rate (eGFR) <60 ml/min per 1.73 m(2).

Purpose of the Study:

  • To systematically review the effects of CRT on patients with CKD.
  • To compare outcomes of CRT in CKD patients versus non-CKD patients.

Main Methods:

  • Searched MEDLINE, Scopus, and conference abstracts (1990-2012) for observational studies and RCTs.
  • Included studies comparing CKD patients with and without CRT, and CKD patients with CRT to non-CKD patients with CRT.
  • Extracted and pooled data on mortality, eGFR, and left ventricular ejection fraction using a random-effects model.

Main Results:

  • Eighteen studies (14 observational, 4 RCTs) were included.
  • CRT showed modest improvement in eGFR (mean difference 2.30 ml/min/1.73 m(2)) and significant improvement in left ventricular ejection fraction (mean difference 6.24%) in CKD patients.
  • Subgroup analysis of RCTs indicated lower rates of death or heart failure hospitalization with CRT in the CKD population. Survival outcomes varied between observational studies and RCTs when comparing CKD and non-CKD patients.

Conclusions:

  • CRT enhances both left ventricular and renal function in heart failure patients with CKD.
  • Further research is warranted to investigate CRT's effects on mortality in CKD patients, especially those with advanced kidney disease.

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

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...

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 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...
Cardiomyopathy II: Dilated Cardiomyopathy01:30

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,...

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...
