Discordance between N-terminal pro-B-type natriuretic peptide and left ventricular end-diastolic pressure in suspected heart failure with a preserved ejection fraction: implications for diagnosis and prognosis.
BACKGROUND Diagnosing heart failure with preserved ejection fraction (HFpEF) remains challenging, as natriuretic peptides and resting haemodynamic measurements reflect complementary but incomplete aspects of myocardial stress and filling pressure. METHODS In this prospective all-comer cohort (UKSH-Trial registration...
