Amyloidosis happens when abnormal proteins, called amyloids, build up in tissues or organs. When these proteins build up in the heart, it’s called cardiac amyloidosis. This buildup can damage the heart and make it harder to pump blood.
This article explains the symptoms of cardiac amyloidosis. If you notice any of these symptoms, talk to your doctor. They can help find out whether amyloidosis or another condition is causing them.
What Types of Amyloidosis Can Affect the Heart?
Two types of amyloidosis are most likely to damage the heart: amyloid light-chain amyloidosis, or AL, and transthyretin amyloidosis, or ATTR. AL amyloidosis is also called primary amyloidosis.
