About this trial
The purpose of this study is to identify changes in heart tissue structure and biological function in patients with heart failure by performing an endomyocardial biopsy (EMB or heart biopsy) during a right heart catheterization (RHC). The ultimate goal is to use this information to develop new treatments for heart failure.
Eligibility criteria
Qualifiers
HFpEF criteria
Age ≥30 years.
Left ventricular ejection fraction ≥50% measured by echocardiography, CMR or MUGA (measured within one year + clinical stability)
Elevated BNP (≥75 pg/ml in sinus rhythm or ≥225 pg/ml in atrial fibrillation/flutter) or NTproBNP (≥225 pg/ml in sinus rhythm or ≥675 in atrial fibrillation/flutter) at baseline. Choice of BNP or NTproBNP is based on availability at each clinical center.
Disqualifiers
1. Inadequate echo or fluoroscopic images.
