Traditional and emerging cardiovascular risk factors in end-stage renal disease

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• End-stage renal disease (ESRD) patients exhibit elevated risks of cardiovascular disease (CVD) and mortality.
• Established risk factors like hypertension, diabetes, smoking, and anemia are more prevalent in ESRD patients.
• Uremic state uniquely alters factors such as hyperparathyroidism, hyperhomocysteinemia, and lipid metabolism.

Purpose of the Study:

• To review cardiovascular risk factors in patients with end-stage renal disease undergoing dialysis.
• To highlight the role of traditional and uremia-specific factors in cardiovascular complications.
• To discuss potential interventions for mitigating cardiovascular risk in this population.

Main Methods:

• Literature review of established and emerging cardiovascular risk factors in dialysis patients.
• Analysis of the impact of hypertension, diabetes, anemia, and uremic milieu on cardiovascular outcomes.
• Examination of novel risk factors including inflammation, sympathetic activity, ADMA, and sleep apnea.

Main Results:

• Hypertension and diabetes are highly prevalent and major contributors to mortality and morbidity in dialysis patients.
• Factors like hyperparathyroidism, hyperhomocysteinemia, disordered lipids, inflammation, high sympathetic activity, and ADMA are significant cardiovascular risks.
• Sleep apnea is associated with nocturnal hypertension and left ventricular hypertrophy.

Conclusions:

• Hypertension control, anemia management, and smoking cessation are crucial interventions for dialysis patients.
• Future strategies may involve managing chronic inflammation, sympathetic overactivity, and endothelial dysfunction.
• Reducing cardiovascular mortality in chronic dialysis patients requires a multifaceted approach addressing numerous risk factors.
