This observational study follows people with cardiac amyloidosis to track exercise performance and clinical outcomes over two years. Participants are evaluated every six months and their data are compared with a retrospective group of heart-failure patients from the MECKI score database. The study aims to find exercise-test measures linked to prognosis and to build a MECKI-like risk score for cardiac amyloidosis.

What it is studying. Whether exercise-test measurements and clinical data predict two-year outcomes in cardiac amyloidosis, and how prognosis compares with heart-failure patients in the MECKI database.

What the researchers hope to learn. Identify which exercise-test and clinical measures are most closely associated with two-year outcomes in cardiac amyloidosis; develop a cardiac-amyloidosis-specific prognostic score similar to the MECKI score; compare prognosis and exercise limitations between cardiac amyloidosis and general heart failure.

What this study is about

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

This study aims to advance the understanding of cardiac amyloidosis, its effects on exercise capacity, and its prognostic implications. By conducting a systematic investigation with particular emphasis on longitudinal evaluation, we aim to provide valuable insights to guide clinical practice and improve the management of patients with cardiac amyloidosis. Our study intends to follow patients for a period of two years, evaluating them every six months. This longitudinal approach allows us to monitor changes in exercise capacity and other relevant clinical parameters over time. Furthermore, it enables the development of a prognostic tool similar to the MECKI score, capable of assessing the risk of adverse events in patients with cardiac amyloidosis based on their exercise performance. By comparing our results with data from heart failure patients already included in the MECKI score database, we also aim to highlight any differences in prognosis between patients with cardiac amyloidosis and those with general heart failure. Finally, we aim to characterize cardiac amyloidosis by differentiating it from general heart failure. By comparing our results with data from heart failure patients already included in the MECKI score database, we can clarify the distinct exercise limitations in cardiac amyloidosis and shed light on how they differ from more conventional heart failure.

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.

Prospective participants with cardiac amyloidosis will have a baseline visit and repeat evaluations every six months for two years. Visits include a cardiopulmonary exercise test (CPET) and clinical assessment of exercise capacity and symptoms; a CPET can be physically demanding. The retrospective arm uses existing MECKI score registry data from previously enrolled heart‑failure patients and does not require new visits.

How the study is structured. A prospective observational cohort: people with cardiac amyloidosis are followed for two years with evaluations every six months. Results will be compared with a retrospective cohort of heart-failure patients already in the MECKI score database.

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

adverse events: Any unwanted medical problem that happens during a study, whether or not it was caused by the treatment. A 'serious' adverse event is one that meets specific criteria, such as causing death, being life-threatening, requiring or prolonging hospital admission, causing significant disability, or another medically important outcome.
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.
ECG: A recording of the heart's electrical activity. QTc is one measurement from it; some drugs are avoided if it is prolonged.
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.
