BNP as a Predictor of Cardiovascular Disease and All Cause Mortality Dr. Thierry Le Jemtel
Outline Role of BNP and probnp as relevant biomarkers in cardiac conditions Role of BNP and probnp as relevant biomarkers in the general population Natriuretic Peptide and Metabolic Regulation
Brain Natriuretic Peptide Natriuretic peptides (NP) are hormones involved in the regulation of blood volume and blood pressure. ProBNP is secreted from the cardiac ventricles in response to increased myocardial wall stress due to volume overload and increased pressure. When probnp is released in the circulation it is cleaved in two equal parts: BNP and probnp
Differences between BNP and probnp: BNP is active probnp is not In whole blood BNP is stable for 24 hours and probnp for 72 hours. Amino acids: 32 for BNP and 76 for probnp. Half life is 20 min for BNP and 120 min for probnp. BNP is cleared by NPR C and neural endopeptidases, probnp by the kidney. BNP normal level is <100 pg/l, probnp normal level is <300 pg/l

Natriuretic Peptide Based Screening and Collaborative Care for Heart FailureThe STOP-HF Randomized Trial Figure Legend: Kaplan-Meier Analysis of Major Adverse Cardiovascular Events in the Full Study Sample and in Participants With BNP 50 pg/mlbnp indicates brain-type natriuretic peptide. Major adverse cardiovascular events included arrhythmia, transient ischemic attack, stroke, myocardial infarction, peripheral or pulmonary thrombosis/embolus, or heart failure. In the full sample, 51 (7.3%) of 697 patients were admitted for major adverse cardiovascular events in the intervention group and 71 (10.5%) of 677 were admitted in the control group. In participants with BNP 50 pg/ml, 35 (13.3%) of 263 were admitted for major adverse cardiovascular events in the intervention group and 45 (19.1%) of 235 were admitted in the control group.
