Abstract
BACKGROUND: Three types of amyloid are responsible for cardiac amyloidosis. Differentiation of the subtype is critical for the disease progression and the therapeutic decision. RESULTS: Myocardial scintigraphy using Tc-PYP is able to differentiate the cardiac amyloid subtype with high sensitivity and specificity. The myocardial uptake of PYP is higher in patients with TTR amyloidosis. CONCLUSION: Non-invasive tests for the detection of cardiac amyloidosis, like myocardial scintigraphy with bone seeking tracers, can play a major role in the diagnosis progression and therapeutic management of patients with cardiac amyloidosis.
