Inhibition of inositol(1,4,5)Trisphosphate generation by endothelin-1 during postischemic reperfusion: A novel antiarrhythmic mechanism.

abstract：BACKGROUND:Patients with chronic stable angina are poorly characterized in terms of biomarkers that help in the assessment of prognosis. We investigated whether plasma levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) may be used as a prognostic marker in patients with chronic stable angina treated with co...
