NOS3 and myocardial infarction: Characteristic impairments in contractility (+dP/dt) and diastolic function (-dP/dt) after MI significantly improved after eNOS delivery, and the effects were reversed by L-NAME administration (+dP/dt: L-NAME group vs Ad.eNOS group: 2023.0±99.8 vs 2396.4±103.2, P < 0.05; -dP/dt: L-NAME group vs Ad.eNOS group: 1817.5±81.9 vs 2104.9±86.4, P < 0.05).
