Hemodynamic determinants of myocardial B-type natriuretic peptide release: relative contributions of systolic and diastolic wall stress.
Although B-type natriuretic peptide (BNP) is widely used as a biomarker for heart failure, the in vivo mechanical stimulus for its cardiac release remains poorly defined. We aimed to characterize the hemodynamic determinants of the transcardiac BNP gradient as a measure of myocardial BNP release by performing a detailed hemodynamic assessment in subjects with a broad spectrum of systolic and di...

متن کاملB Type natriuretic peptide: a good omen in myocardial ischaemia?
The natriuretic peptide family consists of a number of structurally homologous but genetically distinct polypeptide mediators. The peptides are highly conserved across mammalian and invertebrate species and, in humans, are released from various tissues in response to physiological and pathological stimuli. All the peptides have at their core a 17-amino acid disulfide ring essential for receptor...
متن کاملB-type natriuretic peptide in reversible myocardial ischaemia.
BACKGROUND Coronary heart disease is associated with increased B-type natriuretic peptides (BNPs), and, although controversial, may cause exaggerated exercise-induced BNP secretion. We investigated BNP in relation to reversible myocardial ischaemia. MATERIALS AND METHODS Serum N-terminal proBNP (NT-proBNP) was measured before and after an exercise electrocardiogram test (ETT) in 14 patients w...
متن کاملAtrial natriuretic peptide, B-type natriuretic peptide, and serum collagen markers after acute myocardial infarction.
Experimental data suggest that atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) act locally as antifibrotic factors in heart. We investigated the interrelationships of natriuretic peptides and collagen markers in 93 patients receiving thrombolytic treatment for their first acute myocardial infarction (AMI). Collagen formation following AMI, evaluated as serum levels of amin...
