Bicep bunching may be a marker for ATTRwt. According to MedPage Today, spontaneous ruptures of the distal biceps tendon may be a marker of wild-type transthyretin (TTR) cardiac amyloidosis, a single-center study found. The presentation of a tendon rupture, an easily elicited diagnostic sign, in a patient with HFpEF should raise suspicion for wild-type TTR cardiac amyloidosis.
Bicep bunching may be a marker of wild-type transthyretin (TTR) cardiac amyloidosis, potentially giving physicians an easy way to determine the underlying cause of heart failure with preserved ejection fraction (HFpEF) in some patients. Those who were aware, reported that the distal biceps tendon ruptured approximately five years prior to heart failure diagnosis, thus perhaps offering a leading insight.
