Chronic Kidney Disease as a Comorbidity in Heart Failure

Area of Science:

• Cardiology
• Nephrology
• Internal Medicine

Background:

• Heart failure (HF) frequently coexists with declining renal function.
• The heart and kidney exhibit bidirectional pathophysiology, leading to cardiorenal deterioration.
• This cardiorenal interaction complicates treatment and worsens prognosis, increasing hospitalizations and mortality.

Purpose of the Study:

• To review the pathomechanisms of chronic kidney disease (CKD) in heart failure (HF) patients.
• To discuss therapeutic strategies for managing co-existing CKD and HF.
• To highlight the need for novel treatment strategies and biomarkers.

Main Methods:

• Literature review of pathomechanisms.
• Analysis of therapeutic strategies for cardiorenal disease.
• Synthesis of current understanding of HF-CKD interactions.

Main Results:

• Identified common mechanisms driving cardiorenal deterioration.
• Highlighted the negative impact of worsening renal function on HF outcomes.
• Emphasized the challenges in treating combined HF and CKD.

Conclusions:

• The cardiorenal axis is a critical determinant of outcomes in HF patients with CKD.
• Further research into pathomechanisms and biomarkers is essential.
• Integrated therapeutic approaches are needed for effective management.
