Tissue is the Issue: Endomyocardial Biopsy Characterization of Heart Failure with Preserved Ejection Fraction and Incident Cardiac Amyloidosis

Introduction null Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous disease with no proven pharmacologic therapies. Cardiac amyloidosis shares common features of HFpEF, however endomyocardial biopsy data are only available on limited subsets of HFpEF patients. To our knowledge, this is the first study to comprehensively characterize biopsy data for patients referred for HFpEF evaluation. null null null Methods null We...
