【摘要】：目的:采用超声心动图的综合参数检测高血压患者左心室舒张功能,探讨其临床评估价值。方法:选择60例高血压病患者将其纳入高血压组,高血压组患者中30例无左心室肥厚,30例存在左心室肥厚;同期选取60名健康体检者为健康对照组。对两组受试者常规进行M型、彩色及多普勒超声心动图检查与组织多普勒成像(TDI),比较高血压组与健康对照组超声心动图综合参数。结果:高血压组与健康对照组相比舒张期室间隔厚度(IVSd)、舒张期左心室后壁厚度(LVPWd)、左心室重量(LVMI)、左房内径(LAD)和左心室内径(LVD)明显增大;高血压组的心肌等容收缩期峰值速度(s′)、心肌舒张早期速度(e′)、二尖瓣舒张早期最大流速(E峰)和左心室舒张末压(LVEDP)明显增大,瓣环最大运动速度(a′)、二尖瓣舒张末期最大流速(A峰)明显减小;与非左心室肥厚相比,左心室肥厚的e′、E和LVEDP明显增大,a′、A明显减小,差异均具有显著统计学意义(t=-4.39,t=-4.39,t=5.47,t=-8.02,t=6.20,t==18.95,t=16.12;P0.01)。结论:超声心动图综合参数可以评价高血压患者左心室舒张功能损失程度,并可成为是否存在左心室肥厚的评判标准,而组织多普勒成像技术也可作为评价心室舒张功能的一项新手段。
[Abstract]:Objective: to evaluate the clinical value of echocardiographic parameters in detecting left ventricular diastolic function in patients with hypertension. Methods: 60 patients with hypertension were included in the hypertension group. 30 patients without left ventricular hypertrophy were included in the hypertension group, and 60 healthy people were selected as the healthy control group. M-mode, color and Doppler echocardiography and tissue Doppler imaging (TDI) were performed to compare the echocardiographic parameters between the hypertension group and the healthy control group. Results: the diastolic septal thickness (IVSdT), left ventricular posterior wall thickness (LVPWdN), left ventricular weight (LVMI), left atrial diameter (lad) and left ventricular diameter (LVD) were significantly increased in the hypertensive group compared with the control group. Myocardial isovolumic systolic peak velocity, early diastolic velocity, mitral peak early diastolic velocity and left ventricular end-diastolic pressure (LVEDP) were significantly increased in hypertensive group. Compared with non-left ventricular hypertrophy, the E and LVEDP of left ventricular hypertrophy increased significantly, and the differences were statistically significant. The difference was statistically significant (P < 0.05). The difference was statistically significant (P < 0.05), and the difference was statistically significant (P < 0.05), and the difference was statistically significant (P < 0.05), and the difference was statistically significant (P < 0.05), and the peak velocity of mitral annulus was significantly decreased, compared with that of non-left ventricular hypertrophy, the E and LVEDP of left ventricular hypertrophy increased significantly, and the difference was statistically significant (P < 0.05). The difference was statistically significant (P < 0.05), and the difference was statistically significant (P < 0.05), and the difference was statistically significant (P < 0.05). Conclusion: the comprehensive parameters of echocardiography can be used to evaluate the degree of left ventricular diastolic function loss in patients with hypertension, and can be used as a criterion for evaluating the existence of left ventricular hypertrophy. Tissue Doppler imaging can also be used to evaluate ventricular diastolic function.
