Insights

A reduction in the subendocardial viability ratio (SEVR) is a significant predictor of cardiovascular mortality in patients with chronic kidney disease (CKD). Monitoring SEVR may help identify high-risk individuals.

Area of Science:

  • Cardiology
  • Nephrology
  • Biomedical Engineering

Background:

  • The subendocardial viability ratio (SEVR) is a key index of myocardial oxygen supply and demand, derived from pulse wave analysis.
  • Chronic kidney disease (CKD) is associated with increased cardiovascular risk.
  • Understanding predictors of cardiovascular mortality in CKD is crucial for patient management.

Purpose of the Study:

  • To investigate the relationship between SEVR and cardiovascular mortality in patients with stage 3-4 CKD.
  • To determine if changes in SEVR over time correlate with cardiovascular outcomes in this population.

Main Methods:

  • A post hoc analysis of a multicenter, prospective study involving 212 asymptomatic CKD outpatients.
  • Data collected included SEVR measurements, vascular calcifications, and myocardial mass.
  • Patients were followed for 6 months, with cardiovascular mortality as the primary endpoint.

Main Results:

  • SEVR showed inverse correlations with vascular calcifications (r = -0.37) and myocardial mass (r = -0.45).
  • Deceased patients exhibited a significant reduction in SEVR from baseline (1.16 ± 0.31 to 0.68 ± 0.26, p < 0.001).
  • A greater reduction in SEVR during follow-up independently predicted cardiovascular mortality (p < 0.0001).

Conclusions:

  • A decline in SEVR values is a significant predictor of cardiovascular mortality in patients with chronic kidney disease.
  • SEVR may serve as a valuable non-invasive biomarker for risk stratification in CKD patients.
  • Further research is warranted to explore the clinical utility of SEVR monitoring in CKD management.

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: 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...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...

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 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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
