Atrial fibrillation (AF) complicates inherited cardiomyopathies, worsening outcomes. Managing AF in these patients is challenging due to disease-specific factors and cardiac changes.

Area of Science:

  • Cardiology
  • Genetics
  • Electrophysiology

Background:

  • Inherited cardiomyopathies frequently present with or develop atrial fibrillation (AF).
  • The unique pathophysiology of each cardiomyopathy influences AF development and maintenance.
  • AF signifies a critical disease stage, increasing morbidity and mortality.

Purpose of the Study:

  • To review the current understanding of AF in inherited cardiomyopathies.
  • To explore the prevalence, pathophysiology, risk factors, and treatment of AF.
  • To focus on hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia/cardiomyopathy, familial dilated cardiomyopathy, and left ventricular non-compaction cardiomyopathy.

Main Methods:

  • Literature review of current information on AF in inherited cardiomyopathies.
  • Analysis of disease-specific defects and cardiac chamber changes.
  • Examination of treatment challenges in this patient population.

Main Results:

  • AF is a common complication with significant prognostic implications.
  • Pathogenesis of AF is multifactorial, involving genetic defects and structural heart changes.
  • AF management is complex and requires tailored approaches.

Conclusions:

  • AF significantly impacts the clinical course and prognosis of inherited cardiomyopathies.
  • Understanding the interplay between cardiomyopathy type and AF is crucial for effective management.
  • Further research is needed to optimize AF treatment strategies in these complex patients.

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Chromosomal Theory of Inheritance

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Inheritance of Chromatin Structures

Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Non-nuclear Inheritance01:29

Non-nuclear Inheritance

Most DNA resides in the nucleus of a cell. However, some organelles in the cell cytoplasm⁠—such as chloroplasts and mitochondria⁠—also have their own DNA. These organelles replicate their DNA independently of the nuclear DNA of the cell in which they reside. Non-nuclear inheritance describes the inheritance of genes from structures other than the nucleus.
