Heart failure: TNM-like classification.

Area of Science:

• Cardiology
• Clinical Classification Systems
• Heart Failure Management

Background:

• Heart failure staging is crucial in clinical practice.
• The MOGE(S) classification, though TNM-like, has limitations in simplicity and clinical applicability.
• MOGE(S) encompasses morphofunctional characteristics, organ involvement, genetics, etiology, and functional status.

Purpose of the Study:

• To introduce and evaluate a new TNM-like classification for heart failure, named HLM.
• To address the shortcomings of existing heart failure staging systems.
• To propose a classification prioritizing simplicity, clinical utility, and prognostic value.

Main Methods:

• Development of the HLM classification based on TNM staging principles.
• HLM considers heart damage progression (H), lung involvement (L), and peripheral organ malfunction (M).
• Evaluation of HLM's potential for therapeutic strategy planning and economic resource balancing.

Main Results:

• The HLM classification progresses from initial functional impairment to advanced biventricular dysfunction.
• It accounts for varying degrees of lung and peripheral organ involvement.
• HLM is designed for ease of application in real-world clinical settings.

Conclusions:

• The HLM classification offers a more practical and user-friendly approach to staging heart failure compared to MOGE(S).
• Its TNM-like structure enhances clinical usefulness, therapeutic planning, and patient prognosis assessment.
• HLM demonstrates potential for efficient resource allocation in managing complex heart failure cases.
