    Abstract:
    OBJECTIVE: To study the therapeutical effects of Shuangshen Ningxin capsule on miniature swine after myocardial ischemia by intervention. METHOD: Myocardial ischemic model miniature swine induced by self-thrombus via cardiac catheter in left anteriar descending coronary artery (LAD), were administrated Shuangshen Ningxin capsule for 6 days. The changes of coronary arteriography, hemodynamics, biochemistry and pathohistology were observed. RESULT: 6 days after modeling, LAD in myocardial ischemic miniature swine was basically embolized, cardiac output (CO), cardiac index (CI), left cardiac work (LCW) and left cardiac work index (LCWI) obviously lowed, and pathohistological analysis revealed myocardial degeneration, necrosis, fibrosis and inflammatory cell infiltration. After being administered with shuangshen Ningxin capsule 6 days, the degree of self-thrombus blocked LAD reduced, hemodynamic indexes of CO, CI, LCW, LCWI and blood plasm superoxide dismutase (SOD) activity increased, and systemic vascular resistance (SVR), systemic vascular resistance index (SVRI) and malondialdehyde (MDA) content were lowed. on the same time, pathohistological degeneration and necrosis reduced. CONCLUSION: Shuangshen Ningxin capsule has anti-myocardial ischemia effect by improving cardiac muscle systolic function, increasing left cardiac work, inhibiting cardiac muscle cellular membrane lipid peroxidation.
