WebCardiac amyloidosis is a heart condition where misshapen proteins get stuck in and around different parts of your heart. As these proteins build up, your heart struggles to pump blood so it tries to pump harder. Ultimately, the extra effort weakens and damages your heart, causing it to fail. There are many possible causes of cardiac amyloidosis.
