QSYQ Improved hemodynamic alterations. a Values of SBP and DBP, which reflect arterial blood pressures, were reduced in the model group. QSYQ and aspirin increased SBP and DBP towards normal levels; (b) and (c) Values of LVSP, LVEDP, Max dp/dt and Min dp/dt, which reflect the left ventricular pressures, were down-regulated in the model group. QSYQ up-regulated LVSP, LVEDP, Max dp/dt and Min dp/dt, suggesting that QSYQ can regulate hemodynamic alterations induced by ischemia (*P < 0.05, **P < 0.01, ***P < 0.001, other groups vs. model group, n = 8)
