Exploring the Interplay Between Kidney Dysfunction and Cardiovascular Disease

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Chronic kidney disease (CKD) impairs kidney function, necessitating hemodialysis for end-stage renal disease.
• Hemodialysis involves filtering blood externally, requiring arteriovenous (AV) fistula creation.
• CKD is strongly linked to cardiovascular disease (CVD) development.

Purpose of the Study:

• To review the spectrum of complications associated with dialysis and kidney disease.
• To highlight cardiovascular complications in CKD patients undergoing hemodialysis.
• To discuss the molecular mechanisms of CVD in CKD, including nitric oxide (NO) signaling.

Main Methods:

• This is a review article, synthesizing existing research on dialysis and CKD complications.
• It examines complications arising from the hemodialysis procedure itself.
• It explores the molecular pathways contributing to cardiovascular disease in CKD.

Main Results:

• Patients with CKD experience numerous complications, including left ventricular hypertrophy, heart failure, arrhythmias, and coronary heart disease.
• Hemodialysis, while life-sustaining, can lead to complications such as AV fistula failure and intradialytic hypertension.
• Molecular mechanisms, like altered nitric oxide (NO) signaling, contribute to CVD in CKD patients.

Conclusions:

• Dialysis and CKD present significant risks for cardiovascular morbidity and mortality.
• Proper AV fistula creation and management, alongside diligent patient care, are essential to mitigate hemodialysis-related complications.
• Further research into the molecular underpinnings of CVD in CKD is warranted to improve patient outcomes.
