Classification of Infiltrative Heart Diseases MORAL-STAGE System

Area of Science:

• Cardiology
• Pathology
• Medical Classification Systems

Background:

• Infiltrative heart disease (InHD) impairs cardiac function due to abnormal substance deposition.
• Current classification systems for InHD are lacking, hindering standardized diagnosis and management.
• Existing cardiomyopathy classifications, like MOGE(S), provide a model for comprehensive assessment.

Purpose of the Study:

• To introduce the novel MORAL-STAGE classification system for infiltrative heart disease.
• To establish a standardized framework for describing and evaluating InHD.
• To discuss the clinical relevance and potential future developments of the MORAL-STAGE classification.

Main Methods:

• Development of the MORAL-STAGE classification by analogy with the MOGE(S) system.
• Inclusion of ten key features: Morphofunctional characteristics, Organ damage, Risk of cardiac death, Age of presentation/therapy, Localization, Stage/Severity, Treatment, Arrhythmia/Conduction, Genetics, Etiology.
• Review and summarization of the classification's core components and clinical utility.

Main Results:

• The proposed MORAL-STAGE classification offers a structured approach to InHD.
• It integrates diverse aspects of the disease, from pathology to clinical presentation and genetics.
• The classification aims to improve the understanding and clinical management of infiltrative cardiomyopathies.

Conclusions:

• The MORAL-STAGE classification provides a much-needed standardized system for infiltrative heart disease.
• This classification enhances clinical relevance by incorporating multiple disease dimensions.
• Future iterations may further refine the assessment and treatment strategies for InHD.
