Overview
Differentiating Wild-type (Senile) Amyloidosis from other Diseases
Differentials Based on Cardiac Involvement (Heart Failure)
Wild-type (senile) amyloidosis should be differentiated from other causes of heart failure:
Differential Diagnosis | History and Symptoms | Physical Examination | Laboratory Findings | Imaging Findings |
---|---|---|---|---|
|
|
Periorbital purpura: Often occurs with sneezing, coughing or with minor trauma. Indicates capillary involvement of AL type amyloidosis.
