Ultrasonic study of the right heart function of patients with pulmonary hypertension in ICU / 实用医学杂志

ABSTRACT

Objective To investigate the valuable echocardiographic parameters and to evaluate theright heart function of patients with pulmonary hypertension in ICU. Methods From March 2015 to February 2016,30 patients with pulmonary hypertension in the intensive care unit(ICU) of Dongzhimen hospital were enrolled in the experimental group,and another 33 patients without pulmonary hypertension in ICU were enrolled in the control group. All of the patients were given bedside echocardiography examination. Results Significant differences in the right atrial diameter and area ,the base diameter of the right ventricle ,the intermediate diameter portion ,the distal inner diameter of the proximal end of the right ventricular outflow tract ,the main pulmonary artery diameter ,the Tei index and the E/A were observed between the two groups. However ,no significant differences in the right ventricular free wall thickness,TAPSE,RVFAC,VREF and DT were foundbetween the two groups. Conclusion Tei index,the diameter of the right heart and the main pulmonary artery diameter are proposed to be the promising echocardiographic parameters to evaluate the right heart function of patients with pulmonary hypertension in ICU.
