Obsolete Secondary Cardiomyopathy

Secondary cardiomyopathy, also known as acquired cardiomyopathy, refers to a type of heart muscle disease that is caused by external factors or conditions, rather than being a primary disorder of the heart muscle itself. This concept has been largely abandoned in modern cardiology.

• Definition: In the past, secondary cardiomyopathy was defined as a condition where the heart muscle was structurally and functionally abnormal due to an underlying disease or condition that was not directly related to the heart muscle itself (see [12][14]).
• Examples: Secondary cardiomyopathy was previously classified as a separate entity from primary cardiomyopathy, but it is now considered a part of the broader category of cardiomyopathies. Examples of conditions that were once considered secondary cardiomyopathy include:
  • Cardiomegaly caused by chronic hypertension (see [4])
  • Heart muscle disease resulting from systemic diseases such as amyloidosis or sarcoidosis
• Current classification: The concept of secondary cardiomyopathy has been largely replaced by more specific and accurate classifications, such as hypertensive heart disease or cardiac involvement in systemic diseases. Modern cardiology emphasizes the importance of precise language and clear definitions to describe these complex conditions.

Obsolete Secondary Cardiomyopathy Signs and Symptoms

Secondary cardiomyopathy, also known as secondary myocardial disease, was a condition where the heart muscle was affected by an underlying systemic disorder or disease. This type of cardiomyopathy was often associated with other conditions that affected multiple organs.

Signs and Symptoms:

• Chest pain: A common symptom of secondary cardiomyopathy, chest pain could be experienced during physical activity or even at rest.
• Dyspnea (shortness of breath): As the heart's ability to pump blood efficiently decreases, people with secondary cardiomyopathy may experience shortness of breath, especially when engaging in physical activities.
• Edema (swelling): Swelling in the legs, ankles, or feet can occur due to fluid buildup caused by the heart's inability to pump blood effectively.
• Fatigue: People with secondary cardiomyopathy often experience fatigue, which can be a result of the heart not being able to supply enough oxygen and nutrients to the body.
• Arrhythmia (irregular heartbeat): Abnormal heart rhythms or palpitations can occur in people with secondary cardiomyopathy.

Other Possible Symptoms:

• Syncope (fainting): In severe cases, people with secondary cardiomyopathy may experience fainting spells due to a sudden drop in blood pressure.
• Ascites: Fluid buildup in the abdominal cavity can lead to swelling and discomfort.
• Hepatic congestion: The liver may become congested due to fluid buildup, leading to symptoms such as jaundice or ascites.

Important Note:

It's essential to note that these signs and symptoms are associated with obsolete secondary cardiomyopathy. Modern medical understanding and classification of cardiomyopathies have evolved, and the term "obsolete secondary cardiomyopathy" is no longer used in contemporary cardiology. However, the symptoms listed above can still be relevant for other types of cardiomyopathies or heart conditions.

• [14] - This search result mentions signs and symptoms of an underlying systemic cause.
• [15] - This search result lists cardiomyopathy symptoms, which include fatigue, heart palpitations, chest pain, arrhythmia, shortness of breath (dyspnea), swelling (edema) in your legs or ankles, and syncope (fainting).

Based on the provided context, it appears that there are various diagnostic tests for cardiomyopathy, including:

• Cardiac MR (Magnetic Resonance) is used in pediatric ischemic cardiomyopathies for diagnosis, prognosis, and risk assessment [7].
• 99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid scintigraphy can be useful in the aetiological diagnosis of amyloidotic cardiomyopathy [11].
• A CT scan of the heart can show calcium deposits and blockages in the heart arteries [13].

However, it seems that there is limited information on diagnostic tests for "obsolete secondary cardiomyopathy". The term "obsolete" suggests that this type of cardiomyopathy may be less common or no longer a primary concern in modern medicine.

Upon reviewing the search results, I found one relevant article that mentions "alcoholic cardiomyopathy", which is a type of secondary cardiomyopathy [9]. However, it does not provide specific diagnostic tests for obsolete secondary cardiomyopathy.

Another article discusses the importance of genetic counseling, DNA diagnostics, and cardiologic family screening in left ventricular noncompaction cardiomyopathy [3], but again, it does not specifically address diagnostic tests for obsolete secondary cardiomyopathy.

It's worth noting that cardiomyopathy can be separated into primary (genetic, mixed, or acquired) and secondary categories, with the definition and classification of cardiomyopathy evolving over time [15]. However, I couldn't find any specific information on diagnostic tests for obsolete secondary cardiomyopathy.

If you're looking for more information on this topic, I'd be happy to try searching again or provide more general information on cardiomyopathy diagnosis.

Based on the provided context, it appears that there are various types of cardiomyopathies, including hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), and others.

Regarding drug treatment for secondary cardiomyopathy, specifically the obsolete type, I found some relevant information in the search results:

• In result 4, it is mentioned that "Cardiomyopathy treatments don’t cure the condition. However, they can help you manage your symptoms and slow down the disease’s progression." This suggests that drug treatment may be one of the options for managing symptoms and slowing down disease progression.
• Result 9 mentions that management of DCM (dilated cardiomyopathy) focuses on "medications to reduce heart failure symptoms" [9]. While this is not specifically about obsolete secondary cardiomyopathy, it does mention medication as a treatment option for another type of cardiomyopathy.

However, I did not find any specific information in the search results that directly addresses drug treatment for obsolete secondary cardiomyopathy. It's possible that this condition may be rare or not well-represented in the available literature.

If you're looking for more information on this topic, I can try to provide a summary of the relevant content from the provided context:

• Cardiomyopathies are classified into primary and secondary categories [11].
• Secondary cardiomyopathy can be caused by various factors, including infiltrative cardiomyopathy or acute giant cell myocarditis [8].
• Treatment for cardiomyopathy typically involves managing symptoms and slowing down disease progression, but may not cure the condition [4].

Please let me know if you'd like me to summarize any specific points from the context.

Obsolete Secondary Cardiomyopathies: Differential Diagnosis

Obsolete secondary cardiomyopathies refer to conditions where the heart muscle becomes weakened or damaged due to an underlying cause, which is no longer present or has been resolved. The differential diagnosis for these conditions involves identifying the potential causes and distinguishing them from other types of cardiomyopathy.

Causes of Obsolete Secondary Cardiomyopathy

• Genetic: Certain genetic mutations can lead to cardiomyopathy, but if the mutation is corrected or not inherited, it may be considered obsolete.
• Infectious: Infections such as myocarditis can cause cardiomyopathy, but if the infection is treated and resolved, it may be considered obsolete.
• Autoimmune: Autoimmune disorders like lupus can cause cardiomyopathy, but if the condition is managed or goes into remission, it may be considered obsolete.
• Toxic: Exposure to toxins such as chemotherapy agents can cause cardiomyopathy, but if the exposure is stopped and the heart recovers, it may be considered obsolete.

Differential Diagnosis

When diagnosing obsolete secondary cardiomyopathy, clinicians must consider the following:

• Family history: A thorough family history can help identify potential genetic causes.
• Medical history: Reviewing the patient's medical history for previous infections, autoimmune disorders, or toxic exposures is crucial.
• Physical examination: A physical examination can reveal signs of cardiomyopathy, such as heart murmurs or abnormal heart rhythms.
• Imaging studies: Imaging studies like echocardiograms or cardiac MRI scans can help assess the extent of heart damage.
