[Variation in the plasma concentration of B-type natriuretic peptide in emergent paroxysmal atrial fibrillation, in acute pulmonary embolism, in acute coronary syndrome and in dilated cardiomyopathy].

Our research is based on the critical evaluation of plasma concentration variation of B-type natriuretic peptide (BNP)--in emergency--in paroxysmal atrial fibrillation, acute pulmonary edema, acute coronary syndrome and dilated cardiomyopathy. The aim of our research was to assess if the BNP concentration variation may be useful in the diagnosis and therapy. Peptide synthesis takes place mainly in the ventricular myocardium.
