Summary
Peripheral endothelial dysfunction, measured by reactive hyperemia peripheral arterial tonometry index (RHI), is associated with coronary artery disease (CAD) in chronic kidney disease (CKD) patients. Impaired RHI independently predicts cardiovascular events in CKD.
Area of Science:
- Cardiovascular Medicine
- Nephrology
- Vascular Biology
Background:
- Patients with chronic kidney disease (CKD) face a high risk of developing coronary artery disease (CAD).
- Accurate cardiovascular risk stratification is crucial for managing CKD patients.
- Peripheral endothelial dysfunction is a potential marker for cardiovascular risk in CKD.
Purpose of the Study:
- To investigate the association between peripheral endothelial dysfunction and the presence of CAD in CKD patients.
- To determine if peripheral endothelial dysfunction predicts future cardiovascular events in this population.
Main Methods:
- 383 CKD patients with coronary risk factors were enrolled.
- Peripheral endothelial function was assessed using the reactive hyperemia peripheral arterial tonometry index (RHI).
- Coronary artery disease (CAD) was diagnosed via coronary angiography; cardiovascular events were tracked during follow-up.
Main Results:
- CKD patients exhibited significantly lower RHI compared to non-CKD controls.
- Lower RHI was observed in CKD patients with CAD versus those without CAD.
- Reduced RHI independently predicted cardiovascular events and improved risk prediction when combined with the Framingham Risk Score.
Conclusions:
- Endothelial dysfunction is prevalent in CKD patients and linked to CAD.
- Severe endothelial dysfunction serves as an independent and incremental predictor of cardiovascular events in CKD.
- RHI assessment can enhance cardiovascular risk stratification in CKD.

1.1K
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...

01:25Chronic Kidney Disease I: Introduction
1.4K
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 (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...

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...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
