Cardiorenal syndrome: Pathophysiology as a key to the therapeutic approach in an under-diagnosed disease

Area of Science:

• Cardiology
• Nephrology
• Internal Medicine

Background:

• Cardiorenal syndrome describes the interplay between heart and kidney dysfunction.
• Impairment of one organ can lead to dysregulation of the other, either acutely or chronically.

Purpose of the Study:

• To review the epidemiology, definition, classification, pathophysiology, therapy, and outcomes of cardiorenal syndrome.
• To provide a comprehensive understanding of the bidirectional relationship between cardiac and renal systems.

Main Methods:

• Review of existing literature on cardiorenal syndrome.
• Analysis of the five established subcategories of cardiorenal syndrome.
• Examination of therapeutic strategies and clinical implications.

Main Results:

• Cardiorenal syndrome is classified into five types based on etiology, pathophysiology, duration, and dysfunction patterns.
• The classification highlights the spectrum and bidirectional nature of heart-kidney interactions.
• Understanding these interactions is crucial for managing both acute and chronic conditions.

Conclusions:

• Further research is needed to translate current findings into clinical practice.
• A thorough understanding of cardiorenal syndrome is essential for effective therapeutic interventions.
• This review synthesizes current knowledge to guide future clinical management and research.
