Investigating new biomarkers in cardiac transthyretin amyloidosis

Assessment of the Association of New Biomarkers (GDF15, ST2, Galectin-3, TIMP-1, MMP-9, NfL) and Plasma Prothrombotic Potential in the Course of Cardiac Transthyretin Amyloidosis

Observational John Paul II Hospital, Krakow · NCT06345235

This study is testing new blood markers in people with transthyretin amyloidosis to see how they relate to heart failure and blood clot risks, including those who are carriers of the disease but don’t have symptoms yet.

What this trial studies

This observational study aims to explore the role of new heart failure biomarkers in patients with transthyretin amyloidosis (ATTR), particularly focusing on asymptomatic carriers of pathogenic TTR variants. It will assess the prothrombotic potential associated with the disease, which may lead to increased thromboembolic complications. The study will include patients diagnosed with ATTR cardiomyopathy, asymptomatic carriers, and a control group of healthy volunteers, utilizing blood tests to gather relevant data. The findings could enhance understanding of the disease's pathology and improve patient management.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 diagnosed with ATTR cardiomyopathy, asymptomatic carriers of pathogenic TTR variants, or healthy volunteers without ATTR.

Not a fit: Patients under 18 years of age, those unable to provide informed consent, or pregnant and lactating women may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better risk assessment and management strategies for patients with transthyretin amyloidosis.

How similar studies have performed: While there is limited published data on this specific approach, the exploration of biomarkers in cardiac amyloidosis is an emerging field with potential for significant insights.
