Glutathione reverses endothelial damage from peroxynitrite, the byproduct of nitric oxide degradation, in crystalloid cardioplegia.

abstract：BACKGROUND:The concept of natriuretic peptide guidance has been extensively studied in patients with chronic heart failure (HF), with only limited success. The effect of NT-proBNP (N-terminal probrain natriuretic peptide)-guided therapy in patients with acute decompensated HF using a relative NT-proBNP target has not b...
