B-Type Natriuretic Peptide and its Molecular Precursor in Myocardial Infarction Complicated by Cardiogenic Shock

The study reveals the plasma profile of proBNP-derived peptides during myocardial infarction complicated by cardiogenic shock. Peripheral concentrations of NT-proBNP, proBNP, and BNP were highly correlated despite marked differences between assays. The results also suggest an increase in cardiac proBNP processing after myocardial infarction and cardiogenic shock.
