ABSTRACT
Objective To investigate the left ventricular function changes of dobutamine stress echocardiography(DSE) in the patients with chest pain.Methods The left ventricular systolic and diastolic function of patients was evaluated using two-dimensional and pulse Doppler echocardiography by DSE.Results After DSE,among the 18 patients,8 appeared abnormal regional motion in the wall of left ventricle and 10 were normal.The SV and CO of those remained normal were higher than those who appeared abnormal.For both normal and abnormal patients the E/A ration was smaller than 1 when dobutamine was at peak dose.Conclusion Using DSE on chest pain patients was an effective method in evaluating regional and global systolic function of the left ventricle and the effective detection data for left ventricular diastolic function is still to be determined.
