Cardiac Amyloidosis: Causes, Symptoms and Treatment - Cleveland Clinic
There are three main types of amyloidosis that affect your heart (other types can also affect your heart, but that only happens in rare instances). Your body uses light chains as part of your immune system, which defends against germs like viruses and bacteria.
Cardiac Amyloidosis - Johns Hopkins Medicine
What are the most common types of cardiac amyloidosis? The amyloidosis type is determined by the type of protein that abnormally deposits. The two most common types of cardiac amyloidosis are light chain (AL) and transthyretin (ATTR).

Nov 5, 2020 · Cardiac amyloidosis causes biventricular wall thickening and stiffness, HF, and restrictive cardiomyopathy. Poor ventricular filling may cause orthostasis or syncope. Differential diagnosis includes other cardiomyopathies like hypertrophic, restrictive from radiation, infiltrative, and high-output HF.
Cardiac Amyloidosis: An Update on Pathophysiology, Diagnosis, …
Cardiac amyloidosis is a restrictive cardiomyopathy marked by extracellular accumulation of misfolded protein fragments. The systemic amyloidoses are classified by the misfolded precursor protein and display significant heterogeneity in clinical course, prognosis and treatment considerations that depend upon the type of protein involved.
Cardiac Amyloidosis: Types, Causes, Treatment - Verywell Health
Jul 18, 2023 · Cardiac amyloidosis is classified into two main types based on the type of misfolded protein: Light chain amyloidosis and transthyretin amyloidosis. Light chain amyloidosis, also called AL amyloidosis, occurs when misfolded light chain proteins deposit in various organs.
Cardiac Amyloidosis > Fact Sheets - Yale Medicine
There are several types of amyloidosis, each caused by a different protein that forms amyloid fibrils. Two proteins, in particular, are responsible for over 95% of cases of cardiac amyloidosis. Transthyretin amyloidosis (ATTR amyloidosis).

Dec 1, 2017 · AL and ATTR are the 2 main types of amyloidosis that affect the heart. Serum and urine protein electrophoresis are inadequate laboratory tests to screen for AL given low sensitivity, and should be replaced by the serum free light chain assay as well as immunofixation of the serum and urine.
Cardiac Amyloidosis - Symptoms and Causes - Penn Medicine
Cardiac amyloidosis ("stiff heart syndrome") occurs when amyloid deposits take the place of normal heart muscle. It is the most typical type of restrictive cardiomyopathy. Cardiac amyloidosis may affect the way electrical signals move through the heart (conduction system).
