Phenotyping and Characterization of wtATTR-CM (TRACE 1)

Phenotyping and Characterization of Danish Wild-type Transthyretin Amyloidosis Cardiomyopathy Patients: A Cross-sectional Study

Source: ClinicalTrials.gov · Last updated 15 Aug 2025 · Not updated for over 12 months - ask the site whether it is still open

Brief summary (registry, in English)

Descriptive cross-sectional study on 100 consecutive ATTRwt-CM patients reflecting all NAC stages aiming primarily to investigate ATTRwt-CM patient's quality of life (QoL) measures and their relation to ATTRwt-CM severity. Secondarily aiming to investigate the possibility to measure misTTR and fragTTR in plasma and urine and to detect fragTTR in endomyocardial biopsies from ATTRwt-CM patients. To investigate whether misTTR and fragTTR levels are correlated with ATTRwt-CM severity.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Surgery for spinal stenosis

Other illness

  • Known cardiovascular disease including ischemic heart disease, heart failure, atrial fibrillation, presence of a pacemaker, or malignant hypertension. Well-controlled hypertension is acceptable.
  • Suspicion of cardiac amyloidosis assessed through clinical history, physical examination, ECG, and echocardiography focusing on "red flags":
  • Myocardial hypertrophy (septum \>11 mm)
  • Bilateral carpal tunnel syndrome

Other

  • AL amyloidosis (light-chain amyloidosis).
  • Myelomatosis
  • Waldenström macroglobulinemia
    • Group 2: Control group
  • Echocardiography with:
  • Apical sparing in LV-GLS
  • Infiltrative changes in the right ventricle free wall, thickened atrioventricular valves, or thickened atrial septum
  • Symptoms of polyneuropathy
  • Low voltage on ECG or discrepancy between left ventricular thickness and ECG amplitude indicative of low voltage
  • Atrioventricular block (AV block)
  • Elevated troponin I or NT-pro-BNP

Who the study is looking for

  • Patients \> 18 years diagnosed with ATTRwt-CM by:
  • endomyocardial biopsy
  • DPD scintigraphy with Perugini grade 2-3 where variant amyloidosis is ruled out due to genetic testing.
  • Informed oral and written consent
  • Patients \> 18 years
  • Informed oral and written consent

Criteria the registry did not label

  • Group 1: wtATTR-CM patients

Age in the registry: 18 years to - · Sex: All · Accepts healthy volunteers
