NCT05950867
Brief Summary:
To investigate to what extent chronic axonal length-dependent polyneuropathy (CAP) and/or small-fiber neuropathy (SFN) is part of early non-cardiac manifestations of wild-type TTR cardiac amyloidosis (wtTTR-CA).
Consequently, explore whether this could ultimately lead to faster diagnosis and clinical outcome of wild-type TTR cardiac amyloidosis (wtTTR-CA).
Detailed Description:
Patients with chronic axonal length-dependent polyneuropathy (CAP) and/or small-fiber neuropathy (SFN) without well-defined cause will be recruited after a neurological standard routine work-up with NCS (Nerve conduction study) test, EMG, and Sudoscan®, previously performed at the neurology department of UZ-Brussel in normal clinical setting. All participants will be invited to the Neurology and Cardiology department for one visit on one day, for the following assessments:
Following exams will be performed:
* assessment of symptoms, severity, and duration of the polyneuropathy and the use of NTSS-6 and COMPASS31 score for mapping somatosensory and autonomic symptoms
* evaluation of objective polyneuropathy signs, using following scales: mPND, NIS
* Kansas City Cardiomyopathy Questionnaire (KCCQ)
* Electrocardiogram (ECG)
* Echocardiography
The following retrospective data from the medical file will be analyzed:
* assessment of medical history, medical treatment, and demographic data
* assessment of laboratory results (and, if applicable, other exams) extracted from the medical file and previously performed in the context of polyneuropathy workup
* assessment of previously performed NCV/EMG data and Sudoscan®, extracted from the medical file of the participants.
