Rapid ventricular induction of brain natriuretic peptide gene expression in experimental acute myocardial infarction.

abstract：BACKGROUND:Very early (day 4) hospital discharge has recently been proposed for selected patients with acute myocardial infarction (MI). The purpose of this study was to determine the most useful factors for identifying acute MI patients treated with aggressive interventional therapy who could be safely discharged on d...
