ABSTRACT
Background: Amyloidosis is a systemic disease which is caused by an extracellular
deposit of amyloid fibrils of different proteins that self-assembled with an inadequate
coupling that traduces an altered structural conformation. One of the main clinical
manifestations is cardiac amyloidosis that is produced by the infiltration of the myocardium
by amyloid fibril; that lead to a diastolic dysfunction and heart failure with
a poor prognosis.
Clinical case: A 66-year-old female patient with previous diagnosis of breast cancer,
that received surgical treatment and chemotherapy. She arrived at the emergency
room presenting dyspnea at rest associated to a restrictive myocardiopathy of infiltrative
etiology.
Conclusions: Cardiac amyloidosis implies a diagnostic and therapeutic challenge
because due to it is a clinical manifestation of a systemic disease, its manifestation is
heterogeneous.
