Summary
Dilated cardiomyopathy (DCM) genetics are increasingly understood through next-generation sequencing (NGS). Understanding genotype-phenotype correlations is key for personalized DCM management and precision medicine.
Area of Science:
- Cardiology
- Genetics
- Molecular Biology
Background:
- Dilated cardiomyopathy (DCM) is a complex heart condition with a significant genetic component.
- Genetic variability contributes to the diverse clinical presentations of DCM.
Purpose of the Study:
- To review current knowledge on the genetic basis of DCM.
- To highlight genotype-phenotype correlations and their clinical management implications.
- To discuss the role of genetic testing in DCM.
Main Methods:
- Literature review of studies on DCM genetics.
- Analysis of next-generation sequencing (NGS) findings.
- Examination of genotype-phenotype correlations for specific genes (e.g., LMNA, FLNC).
Main Results:
- NGS has identified numerous DCM-associated genes and mutations.
- Mutations in LMNA and FLNC are linked to poor prognosis and arrhythmogenic phenotypes, respectively.
- Pathogenic mutations are found in nearly 40% of DCM patients.
Conclusions:
- A deeper understanding of genotype-phenotype correlations is crucial for personalized DCM patient management.
- Interpreting mutation pathogenicity and the clinical utility of genetic testing require further research.
- Advances in genetic understanding pave the way for precision medicine in DCM.

575
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,...

503
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...

558
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

460
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...

613
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...

358
Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops),...
