[Planning of cardiothoracic surgery for chronic kidney disease patients]

Area of Science:

• Nephrology
• Cardiology
• Cardiovascular Surgery

Context:

• Chronic renal failure (CRF) is closely linked to cardiac diseases, and cardiovascular surgeries carry a risk of postoperative acute kidney injury (AKI).
• Understanding the interplay between cardiac conditions, renal function, and surgical interventions is crucial for patient outcomes.

Purpose:

• To review and synthesize current evidence on managing patients with chronic renal failure undergoing cardiovascular surgeries.
• To compare different surgical strategies (endovascular vs. open repair for aortic aneurysm, CABG/PCI for ischemic heart disease) and their impact on renal function.
• To analyze the relationship between cardiopulmonary bypass (CPB) and AKI, identify risk factors, and explore preventive/therapeutic measures.

Summary:

• This review analyzes data on managing CRF patients during cardiovascular procedures, comparing surgical options and evaluating the impact of contrast media and CPB on AKI.
• It discusses risk factors for AKI post-CPB and examines potential interventions such as furosemide, human atrial natriuretic peptide (hANP), mannitol, and statins.
• Current evidence remains limited, but ongoing research aims to optimize the management of these complex patients.

Impact:

• Provides a comprehensive overview to guide clinical decision-making for managing CRF patients undergoing cardiac surgery.
• Highlights knowledge gaps and emphasizes the need for further research to establish best practices for preventing and treating AKI in this population.
• Aims to improve patient outcomes by optimizing perioperative care strategies for individuals with combined cardiac and renal compromise.
