Follow-up Tc-99  m pyrophosphate cardiac scan for patients with transthyretin cardiac amyloidosis treated with tafamidis

ConclusionA decrease in H/CL ratio was found after tafamidis therapy in patients with ATTR-CA, albeit the magnitude of changes in the H/CL ratio ( ΔH/CL ratio) was not significantly different from that of patients without tafamidis therapy. Future study with larger population might be required to further clarify the effect of tafamidis therapy on myocardial uptake of Tc-99 m PYP.Clinical trial registrationNo clinical trial was conducted in our retrospective study.
