title: Systemic amyloidosis: a clinical challenge.
abstract: This study reports a case of an 82-year-old white woman with a history of congestive heart failure refractory to diuretic therapy who was found to have systemic amyloidosis, confirmed by a rectal biopsy. Cardiac involvement by amyloid should be considered in the differential diagnosis of any patient with heart failure with preserved ventricular systolic function, who does not have evidence of ischaemic heart disease or hypertension. However, the rarity of this disease and the various involvement of different organs and tissues are often responsible for missed or delayed diagnosis. Systemic amyloidosis is a life-threatening disease but an early diagnosis may modify its course; therefore it is important to maintain a high clinical suspicion and to increase the awareness of this overlooked condition among clinicians.
