About this study
Official title: Native T1 Cardiac Magnetic Resonance Imaging for Diagnosis of Cardiac Amyloidosis
The study aims to test the diagnostic accuracy of T1 mapping for the diagnosis of cardiac amyloidosis prospectively. The hypothesis is that T1 mapping in older patients with symptomatic heart failure, increased LV wall thickness and elevated cardiac biomarkers is non-inferior to the reference method to diagnose cardiac amyloidosis (CA).
As secondary measure, a web-based ATTR probability estimator for the diagnosis of CA will be evaluated.
Read the detailed description
Cardiac amyloidosis (CA) is an important differential diagnosis in older patients with symptomatic heart failure with preserved or mid-range ejection fraction and increased left ventricular wall thickness. The prevalence of CA among patients with heart failure and left ventricular (LV) hypertrophy is approximately 13%. However, diagnosis of CA is challenging because specific clinical signs are often lacking.
Amyloid fibrils deposit in the extracellular space of the myocardium increases myocardial T1 values on cardiac magnetic resonance (CMR). Therefore, T1 imaging provides a promising non-invasive method to identify CA.
A preliminary retrospective analysis of 128 patients with increased LV wall thickness identified an area under the curve of 0.9954 (p<0.0001) for native T1 to detect CA. The optimal cut-off value was 1341ms, with a sensitivity of 100% and a specificity of 97%.
The investigators aim to test the diagnostic accuracy of T1 mapping for the diagnosis of CA compared to the reference method prospectively. Moreover, the web-based ATTR probability estimator for the diagnosis of CA will be evaluated.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diagnostic accuracy of T1 mapping for diagnosis of CA (time frame: up to 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04862273, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026; AzTrials last refreshed its copy on 8 Nov 2026.
