高血压病患者左室充盈类型与几何形态及功能变化评价

目的: 探讨高血压病患者左室充盈类型与左室几何形态及功能变化之间的关系。方法: 采用二维、M型和多普勒超声心动图方法测定120例高血压病患者的心脏收缩功能指数:短轴缩短率(FS)、左室射血分数(EF)及舒张功能指数:二尖瓣血流频谱E峰、A峰、加速时间(EAT)、减速时间(EDT)、EA比值、等容舒张时间(IVRT)等。结果: 本研究中有83.5%高血压病患者出现确定的左室肥厚及心室重构,有84%高血压病患者出现左室充盈功能异常。不同左室充盈类型的形态学指标及不同左室形态的充盈指标比较均有显著差异。结论: IVRT是确定左室充盈功能更重要的指标。左室重量指数的增加更为严重地影响左室充盈功能。

Correlation between left ventricular filling type and geometry modality and functional change of left ventricle in patients with hypertension

AIM: To investigate the correlation between the left ventricular filling type and geometry modality and functional change of the left ventricle in patients with hypertension.METHODS: Systolic function indexes (FS and EF) and diastolic function indexes (E, A, EAT, EDT, E A, IVRT) in 120 patients with hypertension were measured by two dimensional ultrasonography (2-DUS) and M-mode and Doppler ultrasound.RESULTS: A rate of 83.5% in patients with hypertension appeared assured plump and configuration changes of left ventricle, and a rate of 84%in patients with hypertension appeared abnormal left ventricular filling function.The morphologic indexes were significantly different clearly in different left ventricular filling types, and the filling indexes were also significantly different in diferent left ventricular shapes.CONCLUSION: IVRT is a more important index than other factors to decide the left ventricular filling function.LVMI plays more important role than other factors in the left ventricular filling function.
