Registry for Patients With and Without Heart Failure

Preserved vs. Reduced Ejection Fraction Biomarker Registry and Precision Medicine Database for Ambulatory Heart Failure Patients (PREFER-HF) Study

Observational Massachusetts General Hospital · NCT03480633

This study is looking to understand different types of heart failure by gathering health information from people aged 18 and older, both with and without the condition, to improve treatment options.

What this trial studies

This observational registry aims to comprehensively examine clinical characteristics, proteomic, metabolomic, genomic, and imaging data to understand the development and progression of different types of heart failure. Patients aged 18 and older, both with and without heart failure, will be enrolled to evaluate distinct heart failure phenotypes and cardiomyopathies, including amyloidosis. The study will collect baseline and one-year follow-up data, including blood samples and clinical outcomes, to optimize precision medicine in heart failure treatment.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a history of clinical symptoms consistent with heart failure.

Not a fit: Patients with end-stage renal disease on dialysis may not receive any benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatments for patients with heart failure.

How similar studies have performed: Other studies have shown success in using similar approaches to improve understanding and treatment of heart failure, indicating this study builds on established methodologies.
