This prospective study follows adults with wild‑type transthyretin (ATTRwt) cardiac amyloidosis who are starting or already on tafamidis and who have no prior atrial tachyarrhythmia or major bradyarrhythmia. Participants have clinical evaluations every six months and rhythm monitoring (including Holter ECG as ordered by the physician); the study records new rhythm disturbances and changes in diuretic dose.

What it is studying. The study is collecting real‑world data on how often atrial tachyarrhythmias and bradyarrhythmias that require a pacemaker or defibrillator occur in ATTRwt patients on tafamidis, and on changes in patients' diuretic (for example, furosemide) dose needs over 18 months. Data are gathered from routine six‑month clinical visits and physician‑requested rhythm monitoring.

What the researchers hope to learn. To measure the cumulative incidence of atrial and bradyarrhythmias requiring pacemaker or defibrillator and to track diuretic dose needs over 18 months in ATTRwt patients treated with tafamidis.

What this study is about

The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.

All ATTRwt patients on tafamidis 61 mg treatment will be clinically evaluated before treatment initiation and subsequently every six months for the eligibility to continue tafamidis treatment, according to Italian Medicines Agency regulations. C onsidering the significant risk of developing heart rhythm disturbances due to cardiac amyloidosis, especially in transthyretin form (ATTRwt), in routine clinical practice a stricter heart rhythm monitoring is recommended in ATTRwt patients. Moreover, particular attention is usually paid for those who present atrio-ventricular and/or intraventricular block at the baseline electrocardiogram. Data about rhythm disturbances and diuretic dose need will be collected during the planned physical examination every six months and the Holter ECG monitoring requested by the physician at the end of every planned clinical evaluation.

Eligibility

The criteria exactly as listed on ClinicalTrials.gov. Only the study team can say whether they apply to you.

Inclusion criteria

  • Diagnosis of ATTRwt amyloidosis.
  • 18 years or older;
  • evidence of cardiac involvement at echocardiography or cardiac MRI.
  • No known prior history of atrial fibrillation or major bradyarrhythmia (second degree atrioventricular block, third-degree atrioventricular block, high-grade atrioventricular block or alternating right and left branch block)
  • female patients who are postmenopausal for at least 1 year before the screening visit
  • patients on therapy or candidates for therapy with tafamidis 61 mg
  • voluntary written consent must be given before performance of any study-related procedure not part of standard medical care with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.

Exclusion criteria

  • Non-ATTR amyloidosis;
  • NYHA class III and IV;
  • Pregnant or nursing women;
  • Previous pacemaker implantation;
  • any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with a fully comprehension of the written consent form

Study description and what participation involves

The registry record has no detailed description beyond the summary above.

AI summaryWhat participation may involve, in plain languageShow ▾Hide ▴

AI-written from the registry record, not the study's own wording. May contain errors or omissions. Check the registry text on this page and the original record ↗ before acting on it.

Give written informed consent. Have a clinical evaluation before starting tafamidis (if applicable) and then about every six months. At those visits the study team will record heart rhythm information and diuretic dose; physicians may order Holter (ambulatory) ECG monitoring at the end of each planned clinical evaluation per usual care. Events and these measurements will be collected prospectively (reported over the study period, including the 18-month outcome window).

How the study is structured. A prospective observational (cohort) study. No treatments are assigned by the study; participants receive usual care and are followed every six months. The study records clinical exams, rhythm monitoring (such as Holter ECG when ordered), and medication dose changes.

Questions you could ask

These questions are suggestions for a conversation with the study team or your own clinician, not advice.

  • This is an observational study, so the study itself gives no treatment. What would taking part involve for me, and would it change my usual care?
  • The listed sites are in Italy. Is any of them reachable for me, and does the study help with travel?
  • Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai

intraventricular
Given directly into the fluid-filled spaces (ventricles) inside the brain, usually through an implanted catheter or reservoir.
baseline
Measurements taken at the start of the study, before any study treatment, so that later results can be compared with them.
electrocardiogram
A recording of the heart's electrical activity. QTc is one measurement from it; some drugs are avoided if it is prolonged.
echocardiography
An ultrasound scan of the heart. A transesophageal echocardiogram is done through a probe passed into the food pipe for a closer view.
MRI
A scan that uses magnets and radio waves, not X-rays, to make detailed pictures of the inside of the body. Some implants and metal objects mean a person cannot have one.
screening visit
The checks done before enrolment to see whether a person qualifies, such as tests, scans or a review of medical history.
Inclusion Criteria
The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
Exclusion Criteria
The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
