Abstract:
Objective To study the right ventricular function of patients with pulmonary thromboembolism by using color Doppler ultrasound.Methods 31 patients with acute pulmonary thromboembolism,compared with 31 vohnteers,were enrolled in this study.The right ventricular anterior wall movement,right ventricular end diastolic volume,right ventricular ejection fraction,and myocardial performance index were observed by echocardiography.Resuits The right atrium diameter,right ventricles diameter,right ventrieular end diastolic volume and pulmonary artery inner diameter in study group were much larger than that in control group (P<0.01),and the right ventricular anterior wall movement and right ventrieular ejection fraction decreased in study group (P<0.01).Tricuspidal annular E peak velocity tended to be decreased,isovolumie relaxation time and isovolumic contraction time were prolonged and myocardial performance index was increased (P<0.01).Right ventricular myocardial performance index showed significant correlation with right ventrieular ejection fraction (r=0.78,P<0.01),isovolumic relaxation time and isovolumic contraction time(rl=0.88,r2=0.57,P<0.01).Conclusion The right ventricular function in patients with pulmonary thromboembelism is decreased and myocardial performance index is a sensitive index which can be used to reflect right ventricular function in pulmonary thromboembolism.
