Insights

Left ventricular hypertrophy (LVH) affects over 20% of chronic kidney disease (CKD) patients. Key risk factors include cardiovascular disease history, high blood pressure, obesity, and low calcium levels.

Area of Science:

  • Nephrology
  • Cardiology
  • Internal Medicine

Background:

  • Left ventricular hypertrophy (LVH) is a known cardiovascular risk in chronic kidney disease (CKD).
  • The prevalence and specific risk factors for LVH in predialysis CKD patients remain underexplored.

Purpose of the Study:

  • To investigate the prevalence of LVH in predialysis CKD patients.
  • To identify factors associated with increased left ventricular mass index (LVMI) in stages 3-5 CKD.

Main Methods:

  • Cross-sectional analysis of 1185 participants from the Chronic Kidney Disease Japan Cohort (CKD-JAC) study.
  • LVMI was measured, with LVH defined as LVMI >125 g/m² (males) or >110 g/m² (females).
  • Multivariate logistic regression identified independent risk factors for LVH.

Main Results:

  • LVH was present in 21.7% of the CKD cohort.
  • Independent risk factors for LVH included prior cardiovascular disease, elevated systolic blood pressure, higher body mass index, and lower serum calcium levels.
  • Diabetes mellitus was the underlying cause in 41.3% of patients.

Conclusions:

  • Baseline data from the CKD-JAC study highlight significant associations between LVH and specific risk factors in predialysis CKD.
  • Further longitudinal studies are necessary to determine the prognostic implications of LVH in this patient population.

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...

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...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

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...

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...
Heart Failure Drugs: Diuretics01:22

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
