Cardiac amyloidosis: a case report and therapeutic implications

Primary amyloidosis with cardiac involvement presenting as congestive heart failure (CHF) usually carries an unfavorable prognosis, with median survival of about 6 months. We are reporting a case of cardiac amyloidosis with an initial presentation of CHF in which the patient survived for more than 9 years. The prognosis most likely depends on the period of disease remission (i.e., negative serum and urine immunoelectrophoresis), which, in turn, depends on response to chemotherapy.
