ABSTRACT
Aim To observe the improved effects of Shuangshen Ningxin capsule on ventricular remodeling and wall motion in myocardial ischemic miniature swine induced by thrombus.Methods Myocardial ischemic model miniature swine induced by self-thrombus via cardiac catheter in left anterior descending coronary artery(LAD)were administrated Shuangshen Ningxin capsule for 6 days.The changes of cardiac form,left heart systolic and diastolic function,left ventricular wall motion were observed by the technology of conventional ultrasound and Doppler tissue imaging.Results 6 days after myocardial ischemia and administration,miniature swine of model group showed ventricular wall thinning,chambers heart dilating,ventricle remodeling and wall motion weak,but Shuangshen Ningxin capsule obviously lowered left ventricular internal diameter at end-diastole(LVIDd),left ventricular internal diameter at end-systole(LVIDs),end-systolic volume(ESV),end-diastolic volume(EDV)and isovolumic relaxation time(IVRT),and increased ejection fraction(EF),tissue velocity and tissue trace of left ventricle anterior wall cardiac apex segment.Conclusion Shuangshen Ningxin capsule has anti-myocardial ischemia effect by improving left ventricular remodeling,increasing left cardiac work,improving left heart systolic and diastolic function and increasing left ventricular wall motion.
