nervus medianus
bindweefselschede of cardiaal
7.Documentatie dat primaire (lichte keten) amyloïdose ziekte is geëvalueerd en
uitgesloten
8. Bewijs van NYHA-classificatie I, II, III of IV

Exclusion Criteria

1. Chronic use of diflunisal, TTR stabilizer, tauroursodeoxycholate,
doxycycline, digitalis, patisaran, calcium channel blockers, investigational
drug(s) or other experimental interventions, other than tafamidis,
independently or as part of a study within 30 months prior to enrollment, or

3. Liver and/or heart transplant, or implanted cardiac mechanical assist device.
