Insights
Hypertrophic cardiomyopathy (HCM) has been known by over 75 names due to its complex nature. This study reviews HCM nomenclature and proposes a new classification for better diagnosis and treatment.
Area of Science:
- Cardiology
- Genetics
- Pathology
Background:
- Hypertrophic cardiomyopathy (HCM) presents significant diagnostic and therapeutic challenges due to its heterogeneous morphology and function.
- The condition has historically been known by over 75 different names, complicating consistent understanding and management.
- Echocardiographic classification of HCM has been difficult for over 40 years.
Purpose of the Study:
- To review the historical nomenclature of hypertrophic cardiomyopathy.
- To propose a novel classification system for HCM.
- To enhance clinical and surgical cardiologists' understanding of HCM's diverse aspects.
Main Methods:
- Comprehensive literature review of HCM nomenclature and classification systems.
- Analysis of morphological and functional heterogeneity in HCM.
- Development of a proposed new classification framework.
Main Results:
- Identified over 75 historical names for hypertrophic cardiomyopathy.
- Highlighted the persistent challenges in diagnosing and classifying HCM.
- Proposed a new classification aimed at improving clinical and surgical management.
Conclusions:
- A unified and practical classification is crucial for understanding HCM's clinical behavior and prognosis.
- The proposed classification aims to simplify the approach to HCM diagnosis and treatment.
- Standardizing HCM terminology and classification will benefit patient care and research.
Abstract:
Hypertrophic cardiomyopathy (HCM) is a clinical condition, but its name has been subjected to frequent changes over the years, largely because of its morphological and functional heterogeneity, which leads the clinician who is focused on its study to have difficulty in understanding how to diagnose it and when and how to treat it. Regarding its name, it has been called in more than 75 different ways, and it has being classified with difficulty through echocardiography for more than 40 years. Today, it is necessary to understand that the diverse phenotypic behavior, as well as the evolutionary stages of the disease, must be approached in a practical and effective way, so that it easier to understand its clinical behavior and prognosis, as well as the therapeutic needs in each particular case. We review the aspects related to the name of the condition and propose a new classification that could provide the clinical and surgical cardiologist a better understanding of HCM in its various morphological and functional aspects.
