- W2363600003 abstract "Objective To investigate the value of echocardiography in assessing the right heart function of patients with chronic obstructive pulmonary disease( COPD). Methods Thirty-one COPD patients who were treated in department of respiratory of the First Hospital of Ningbo City from January 2012 to January 2013,were selected as study group,and thirty-one age-matched healthy physical examiners were included in control group during the same period. The parameters of right heart function of two groups were measured by echocardiography according to 2010 guideline of American society of echocardiography( ASE). Results Comparison of various diameter of right heart: the left to right diameter,up and down diameter and area of right atrium,and inside diameter of right ventricle basal segment,area of right ventricle,proximal inside diameter of PLAX and PSAX RVOT,the diameter of pulmonary artery and RVWT in COPD group were significantly larger than those in control group( P 0. 05). Comparison of right heart systolic function: there were no significant difference in fractional area changes( FAC) and tissue Doppler-derived tricuspid lateral annular systolic velocity( DTIS) between two groups( P 0. 05); The tricuspid annular plane systolic excursion( TAPSE) and absolute value of right ventricular lateral wall strain( RV-strain) in COPD group were significantly smaller than those in control group( P 0. 05),while the right ventricular myocardial performance index( RV-MPI) in COPD group was bigger than that in control group( P 0. 05). Comparison of rigyt heart diastolic function: there was no significant difference in DTIe,DTIa,tricuspid valve E wave and A wave( TVE and TVA),and TVE / DITe( E /e) between two groups( P 0. 05),while the TVE / TVA( E / A) in COPD group was significantly smaller than that in control group( P 0. 05). Conclusion The echocardiography can assess the function and structure of right heart quantitatively,and right heart size of COPD patients is greater,and systolic and diastolic function has decreased to some extent." @default.
