目的 探讨高血压伴脑卒中患者右室结构和舒张功能的关系。方法 应用超声心动图对照观测 86例高血压伴脑卒中患者、62例高血压患者及 60例对照组的右心室结构和功能。结果 高血压组与对照组比较右室舒张功能减退 ,表现为三尖瓣E峰减低 ,A峰增高 ,E/A比值变小 ,快速充盈分数 (RFF)、1 /3充盈分数 (1 /3FF)和校正的充盈速率峰值 (PFR)均减低、下降时间 (DT)延长。高血压伴发脑卒中可进一步加重右室舒张功能损害 ,其中以A峰、E/A ,PFR表现更为显著 ,右室壁厚度较高血压组和对照组明显增加 ,且左、右心室舒张功能参数间有显著相关关系。
Objective It is to explore the relationship between right ventricular (RV) structure and diastolic function in essential hypertension (EH) complicated with stroke. Methods The RV structure and diastolic function of 86 cases with EH with complication of stroke, 62 cases with EH and 60 cases healthy were determined echocardiography and compared. Results The RV diastolic function of patients with EH decreased, compared with control group, which showed the RV early peak velocity (E) lessened, the arterial peak velocity (A) was rose, the ratio of E/A, the rapid filling fraction (RFF), the 1/3 filling fraction (1/3FF) and the peak filling rate corrected to stroke volume (PFR) lessened and the deceleration time (DT) lengthened compared with those of normal subjects. Essential hypertension complicated with stroke could make more serious on RV diastolic function. Especially, Peak velocity (A), E/A and PFR were further damaged, RV wall thickness increased and obvious correlation was found on the parameter of diastolic function between right and left ventricle. Conclusion RV wall and ventricular septal thickness are maybe the main factor of affecting RV diastolic function in EH complicated with stroke.
