Understanding cardiac amyloidosis in heart failure with preserved ejection fraction

Cardiac Amyloidosis in Heart Failure Patients With Preserved Ejection Fraction

Observational National Taiwan University Hospital · NCT04587648

This study is trying to find out how common a specific type of amyloidosis is in older patients with heart failure that has preserved ejection fraction, to help improve how we diagnose and treat this condition.

What this trial studies

This observational study aims to investigate the underlying causes of heart failure with preserved ejection fraction (HFpEF), particularly focusing on the role of cardiac amyloidosis. It will involve patients aged 60 and older, or those aged 50 with specific conditions, who have been diagnosed with HFpEF. The study will assess the prevalence of wild-type transthyretin amyloidosis among these patients using diagnostic methods such as scintigraphy. By identifying the presence of amyloid deposits, the study hopes to improve diagnosis and treatment strategies for HFpEF.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 60 and older, or those aged 50 with carpal tunnel syndrome or spinal stenosis, who have been diagnosed with HFpEF.

Not a fit: Patients with unstable coronary artery disease or a history of heart failure with reduced ejection fraction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better diagnosis and targeted treatments for patients suffering from HFpEF caused by cardiac amyloidosis.

How similar studies have performed: While studies on cardiac amyloidosis exist, the specific focus on its prevalence in HFpEF patients is less explored, making this approach relatively novel.
