Dilated Cardiomyopathy 1z
Disease Details
Family Health Simplified
- Description
- Dilated cardiomyopathy 1Z is a genetic disorder characterized by the dilation and impaired contraction of the left ventricle, eventually leading to heart failure.
- Type
- Dilated Cardiomyopathy 1Z (DCM1Z) is a type of heart disease characterized by the dilation and impaired contraction of the left or both ventricles. The genetic transmission of DCM1Z is autosomal dominant.
- Signs And Symptoms
-
Signs and symptoms of dilated cardiomyopathy (DCM) can include:
- Shortness of breath, especially during physical exertion or while lying flat
- Fatigue and weakness
- Swelling in the legs, ankles, and feet (edema)
- Swelling of the abdomen due to fluid buildup (ascites)
- Persistent cough or wheezing, particularly when lying down
- Irregular or rapid heartbeats (arrhythmias)
- Reduced ability to exercise
- Lightheadedness or fainting (syncope)
These symptoms result from the heart's decreased ability to pump blood effectively, leading to the aforementioned issues. - Prognosis
- The prognosis of dilated cardiomyopathy (DCM) varies based on the underlying cause, disease severity, response to treatment, and patient's overall health. While some individuals may experience stable conditions with appropriate management, others may progress to advanced heart failure requiring interventions like mechanical support or heart transplantation. Early diagnosis and treatment can improve outcomes, but the condition may still be associated with significant morbidity and mortality. Regular follow-up with a cardiologist is essential for optimal management.
- Onset
- Dilated cardiomyopathy (DCM) typically has an onset in the third or fourth decade of life, although it can occur at any age. The condition is characterized by the dilation and impaired contraction of the left or both ventricles, leading to heart failure and arrhythmias.
- Prevalence
- The prevalence of dilated cardiomyopathy (DCM), including subtype 1Z, varies widely depending on the population and diagnostic criteria used. In general, DCM affects approximately 1 in 250 to 1 in 500 adults. Specific data on the prevalence of the 1Z subtype may not be well-documented, but the overall condition is a significant cause of heart failure and cardiac transplantation.
- Epidemiology
- Dilated cardiomyopathy (DCM) is a condition characterized by the dilation and impaired contraction of the left or both ventricles of the heart. The prevalence of DCM varies, but it is estimated to affect approximately 1 in 2,500 to 1 in 5,000 adults in the general population. It can occur at any age but is most commonly diagnosed in middle-aged individuals. Men are more frequently affected than women. DCM has a diverse etiology, including genetic factors (familial DCM), infections, toxins, metabolic disorders, and systemic diseases. Approximately 20-50% of DCM cases are thought to be hereditary, involving mutations in more than 50 different genes.
- Intractability
- Dilated cardiomyopathy (DCM), including the subtype dilated cardiomyopathy 1Z (DCM1Z), can be challenging to manage and treat. While it may not be entirely intractable, meaning untreatable, it often requires ongoing and complex management. Treatment typically focuses on managing symptoms and slowing disease progression through medications, lifestyle changes, and in some cases, implantable devices or heart transplantation. The effectiveness of these treatments can vary depending on the individual case.
- Disease Severity
- Dilated Cardiomyopathy Type 1Z (DCM1Z) is a genetic form of dilated cardiomyopathy characterized by the enlargement and impaired contraction of the left ventricle or both ventricles of the heart. As for disease severity, it can vary widely among individuals. Some may exhibit mild symptoms and maintain a relatively normal lifestyle, while others can experience severe heart failure requiring medications, devices like pacemakers, or even heart transplantation. Disease severity is influenced by multiple factors, including the specific genetic mutation, age at diagnosis, and overall health of the individual.

- Pathophysiology
-
Pathophysiology: The pathophysiology of Dilated Cardiomyopathy (DCM) involves the enlargement and stretching of the heart's ventricles, primarily the left ventricle, which impairs its ability to pump blood efficiently. This condition can result from genetic mutations, infections, toxins, and other diseases affecting the heart muscle. The compromised contractile function leads to reduced cardiac output, increased ventricular volumes, and ultimately heart failure. Neurohormonal activation and remodeling processes further deteriorate cardiac function.
Nan: The term "nan" is unclear within the context of diseases. If "nan" pertains to nutritional needs, there are no specific dietary recommendations exclusive to Dilated Cardiomyopathy, but general heart health advice such as low sodium intake, moderated fluid intake, and balanced nutrition may be beneficial. If "nan" stands for something else, please provide additional context. - Carrier Status
- "Carrier status" for dilated cardiomyopathy 1Z (DCM1Z) typically means that an individual carries one copy of a mutated gene that is associated with the disease. This person may not display symptoms but can pass the mutation to their offspring. In some autosomal dominant forms of DCM, carriers may eventually develop symptoms.
- Mechanism
-
Dilated cardiomyopathy 1Z (DCM1Z) is a form of dilated cardiomyopathy, a condition characterized by an enlarged and weakened left ventricle, impeding its ability to pump blood efficiently. The molecular mechanisms of DCM1Z are primarily linked to genetic mutations. Specifically, mutations in the RBM20 gene have been identified as a cause.
The RBM20 gene encodes the RNA-binding protein 20, which plays a crucial role in the splicing of pre-mRNA, particularly for genes essential in cardiac function, such as TTN (titin). Titin is a giant protein that acts as a molecular spring, contributing to the elasticity and integrity of the cardiac muscle. Mutations in RBM20 can lead to abnormal splicing of TTN and other target genes, resulting in defective titin proteins or misregulated expression of proteins critical for cardiac structure and function. This disrupts the contractile machinery and structure of heart muscle cells, leading to the progressive dilation and weakening of the cardiac muscle observed in DCM1Z. - Treatment
-
Dilated Cardiomyopathy (DCM) 1Z is a subtype of dilated cardiomyopathy, a condition characterized by the dilation and impaired contraction of the left ventricle.
