Insights
Cardiovascular disease is a leading cause of death in dialysis patients. This article explores elevated homocysteine levels, their cardiovascular impact, and treatment in chronic kidney disease.
Area of Science:
- Nephrology
- Cardiology
- Biochemistry
Context:
- Cardiovascular disease (CVD) is the primary cause of mortality in patients undergoing maintenance dialysis for chronic renal failure (CRF).
- Elevated plasma homocysteine levels are increasingly recognized as a significant risk factor for atherosclerotic lesions in this vulnerable population.
- Understanding the specific causes and mechanisms of hyperhomocysteinemia in CRF is crucial for effective cardiovascular risk management.
Purpose:
- To identify and discuss the key factors contributing to hyperhomocysteinemia in patients with chronic renal failure.
- To elucidate the toxic mechanisms by which elevated homocysteine levels adversely affect the cardiovascular system.
- To outline current and potential treatment strategies for managing hyperhomocysteinemia and mitigating cardiovascular risk in dialysis patients.
Summary:
- This review examines the etiology of hyperhomocysteinemia in chronic renal failure (CRF) patients on maintenance dialysis.
- It details the detrimental effects of high homocysteine on the cardiovascular system, contributing to atherosclerosis.
- The article also covers therapeutic interventions aimed at normalizing homocysteine levels and reducing cardiovascular mortality.
Impact:
- Provides critical insights into a major modifiable risk factor for cardiovascular disease in end-stage renal disease.
- Highlights the importance of monitoring and managing homocysteine levels in dialysis patients.
- Offers a foundation for developing targeted therapies to improve cardiovascular outcomes in this high-risk group.
Abstract:
Cardiovascular disease constitute the main cause of death in chronic renal failure patients on maintenance dialysis. During the last years one of the suspected cause promoting atherosclerotic lesions in this group of patients has been increased plasma homocystein level. The following article presents selected causes of hyperhomocysteinemia in chronic renal failure patients, mechanism of their toxic effect on cardiovascular system and methods of treatment of these disturbances.
