Cardiomyopathy III: Hypertrophic Cardiomyopathy

611
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiomyopathy V: Interprofessional Care

574
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy I: Introduction and Classification

748
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Area of Science:

  • Veterinary Medicine
  • Proteomics
  • Cardiovascular Disease

Background:

  • Plasma biomarker discovery in veterinary medicine is challenging due to limited understanding of disease pathophysiology.
  • Feline hypertrophic cardiomyopathy (fHCM) is the most common cardiac disease in cats with complex, not fully understood causes.

Purpose of the Study:

  • To identify novel plasma biomarkers for fHCM using SWATH-MS proteomics.
  • To further elucidate the pathogenesis of fHCM.

Main Methods:

  • Collected plasma from 20 cats (10 healthy controls, 10 with fHCM diagnosed by echocardiography).
  • Utilized SWATH-MS proteomics for quantitative analysis of plasma samples.
  • Analyzed dysregulated proteins using DIA-NN software.

Main Results:

  • Identified 40 dysregulated plasma proteins in fHCM cats.
  • Key proteins involved in innate/humoral responses (complement C7/C9, properdin), blood coagulation (fibrinogen, fibulin-1), lipid metabolism (apolipoproteins), and inflammation (transthyretin, plasminogen).

Conclusions:

  • Dysregulated proteins suggest potential fHCM biomarkers for early detection before clinical signs.
  • Proteomic changes indicate critical pathways for earlier intervention and improved treatment.
  • Cats with fHCM may serve as a translational model for human hypertrophic cardiomyopathy (hHCM).
