Cardiorenal risk as a new frontier of nephrology: research needs and areas for intervention

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• High cardiovascular morbidity and mortality are significant challenges in renal disease management.
• Mild kidney disease, indicated by elevated serum creatinine, affects approximately 5% of the population.
• Hypertension, hyperlipidaemia, and diabetes are major risk factors for renal failure.

Purpose of the Study:

• To highlight the multifaceted risks contributing to cardiovascular disease in renal failure patients.
• To emphasize the need for further research into the optimal follow-up of patients with mild renal insufficiency.
• To identify key areas for improving understanding and management of renal disease and its cardiovascular complications.

Main Methods:

• Review of known risk factors associated with renal disease and cardiovascular complications.
• Discussion of the mechanisms by which these factors contribute to cardiovascular disease, including oxidative stress.
• Identification of knowledge gaps and areas for future research in patient follow-up and risk factor identification.

Main Results:

• Several factors amplify cardiovascular disease risk in renal failure: anaemia, volume expansion, hormonal imbalances (angiotensin II, aldosterone), high calcium-phosphate product, inflammation, hyperhomocysteinaemia, and impaired nitric oxide synthesis.
• These factors contribute to cardiovascular damage by increasing oxidative stress.
• Optimal follow-up strategies and identification of treatment-resistant patients with mild renal insufficiency require further investigation.

Conclusions:

• Managing cardiovascular risk in renal disease necessitates a comprehensive approach addressing multiple contributing factors.
• Further research is essential to refine patient follow-up protocols and understand the genetic and environmental precursors of renal insufficiency.
• Linking identified risk factors to measurable renal and cardiovascular outcomes will enhance knowledge of disease progression and risk stratification.
