【摘要】 目的应用超声心动图研究肺动脉高压患者左室舒张功能变化情况。方法选择2013年9月~2014年9月在我院接受治疗的肺动脉高压患者64例纳入实验组,选择同期在我院进行健康体检者64例纳入对照组,两组人员性别、年龄比较无统计学意义(P>0.05)。两组人员均行超声心动图检查,并比较相关检查指标。结果实验组和对照组比较右室显著扩大,RVDD增大,LVDD减小。检测二尖瓣血流速,发现E峰值、E/A、二尖瓣E峰值、Ea/Aa均显著降低。结论肺动脉高压状态下左心舒张功能降低,而收缩功能未受影响。更多还原

【Abstract】 Objective Echocardiography was used to research changes of left ventricular diastolic function in patients with pulmonary hypertension.Methods Sixty-four patients in our hospital for treatment with pulmonary arterial hypertension in September 2013 ~September 2014 were chosed in the experimental group,and another 64 cases for physical examination in our hospital at the same time were selected as control group.The gender and age of the two groups were no statistical significant(P > 0.05).The two groups were performed ultrasound cardiogram and the relevant parameters were compared.Results Compare the experimental group with the control group,the former s right ventricular expanded significantly,RVDD increased and LVDD decreased.Detection of mitral valve blood flow velocity showed that the peak E,E/A,mitral E peak and Ea/Aa all reduced significantly.Conclusion In the condition of pulmonary hypertension,left cardiac diastolic function is reduced while systolic function is not affected.更多还原
