Cardiovascular disease in dialysis patients

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Cardiovascular disease (CVD) is the primary cause of mortality in end-stage renal disease (ESRD) patients on maintenance haemodialysis (HD).
• CVD mortality in HD patients is significantly elevated (20-fold) compared to the general population.
• The majority of maintenance HD patients exhibit existing CVD, often linked to ventricular hypertrophy and uraemic factors.

Purpose of the Study:

• To review and elucidate the impact of non-traditional cardiovascular risk factors in patients undergoing haemodialysis.
• To provide a foundation for improved prevention and treatment strategies for CVD in this vulnerable population.

Main Methods:

• This is a review article.
• Focuses on summarizing existing literature regarding non-traditional CVD risk factors in HD patients.
• Synthesizes information on factors contributing to CVD in the uraemic milieu.

Main Results:

• Haemodialysis patients face numerous non-traditional CVD risk factors.
• These include chronic volume overload, anaemia, inflammation, oxidative stress, and chronic kidney disease-mineral bone disorder.
• The 'uraemic milieu' significantly contributes to cardiovascular complications.

Conclusions:

• Understanding non-traditional CVD risk factors is crucial for managing cardiovascular health in ESRD patients on HD.
• Addressing these factors is essential for reducing the high CVD burden and mortality in this population.
• Further research into these specific risk factors can guide targeted interventions.
