Infiltrative Heart Disorders
Infiltrative heart disorders are a group of diseases characterized by the accumulation of abnormal substances in the heart muscle. These conditions can impair heart function and lead to complications such as heart failure, arrhythmias, and conduction abnormalities.
Causes of Infiltrative Heart Disorders
The most common causes include:
Amyloidosis:
Deposits of abnormal amyloid proteins in the heart tissue.
Sarcoidosis:
Granulomas (clusters of immune cells) forming in the heart muscle.
Hemochromatosis:
Excessive iron deposition in the heart.
Fabry disease:
A genetic disorder causing lipid accumulation.
Gaucher disease:
A rare metabolic disorder that can involve the heart.
Symptoms
Common signs and symptoms include:
Shortness of breath
Fatigue and weakness
Swelling in the legs and abdomen
Irregular heartbeats (arrhythmias)
Syncope (fainting episodes)
Diagnosis
To confirm infiltrative heart disease, the following tests are used:
Echocardiography:
Echocardiography:
To assess the structure and function of the heart.
Cardiac MRI:
Cardiac MRI:
Provides detailed images of heart tissue.
Endomyocardial biopsy:
Endomyocardial biopsy:
A definitive test to analyze heart tissue.
Blood tests and genetic testing:
Blood tests and genetic testing:
To diagnose specific conditions like Fabry disease or amyloidosis.
Treatment Approaches
Treatment depends on the underlying cause and may involve:
Medications:
Diuretics, beta-blockers, and specific drugs such as tafamidis (for amyloidosis) or enzyme replacement therapies (for Fabry disease).
Lifestyle modifications:
A low-sodium diet, exercise, and fluid management.
Iron reduction therapy:
For hemochromatosis.
Immunosuppressive therapy:
For sarcoidosis.
Heart transplant:
In severe cases.
Conclusion
Early diagnosis and proper management of infiltrative heart disorders can significantly improve the quality of life. Regular check-ups and genetic counseling are recommended for patients with a family history of these conditions.
