ABSTRACT
Objective To study the therapeutic effects of Enalapril on hemodynamic indexes in cardiac shock dogs induced by acute right ventricular myocardial infarction(RVMI).Methods Models of RVMI accompanied with cardiac shock were induced by ligating coronary artery.Dogs were randomly divided into three groupscontrol group,fluid replacement group and Enalapril group.The hemodynamie indexes including mean arterial pressure(MAP),cardiac output (CO),right atrial pressure(RAP)and right ventrieular systolic pressure(RVSP)were measured before and immediately after RVMI model establishment,and 1 hour and 1 week after the treatment.The therapeutic effects were evaluated. Results After rapid fluid replacement treatment,RAP became higher and the hemodynamics deteriorated.After Enalapril treatment,RAP decreased and CO increased.Conclusion When RVMI in large area occurs,fluid replacement would further deteriorate the heart function of left and right ventricles when RAP≥13 mmHg,and Enulapril fluid replacement would reduce the right ventricle load and improve shock.
