Heinrich-Heine University, Duesseldorf300 enrolled

Overview

The aim of this study is measurement of expression and activity of RBC eNOS in different clinical cohorts of patients with coronary artery disease and acute coronary syndrome and to investigate the importance of the NO-stimulated reaction cascade in terms of sGC and PKG.
