[Hemodynamic study on nitroglycerin compared with Salvia miltiorrhiza].

Unlabelled: This report investigated the hemodynamic changes of both nitroglycerin and Salvia miltiorrhiza (Co.) concerning pulmonary capillary-wedge (PCW), mean pulmonary artery pressure (MPAP), cardiac output (CO), cardiac index (CI), systemic mean pressure (SMP), and heart rate (HR). In 20 patients with heart diseases of normal cardiac function, nitroglycerin were compared with Salvia miltiorrhiza (Co.) using Swan-Ganz Catheter, which were self-compared.
Result: (1) Both drugs had the similar vaso-dilating effects, reduced the filling pressure of left ventricle and increased the cardiac output but different in the time of appearance and duration, particularly concerning CO and CI. (2) The effect of Salvia miltiorrhiza (Co.) was markedly superior to the nitroglycerin. The action of former was more persistent and the improvement of cardiac function was better than that of latter.
