应用二维多普勒超声对36例中年和54例老年人的高血压性在室肥厚（LVH）及心功能状态进行分析比较。结果：中年组LVH类型：不对称性室间隔肥厚(ASH）占40%,对称性肥厚（CH）46％。扩张性肥厚（DH）占14％；老年组：ASH23%，CH26％，DH51％。将中年组和老年组分别同正常对照组比较，除中年组LVDd、LVV、EF及CO差异无显著性外，其余各指标差异均有显著性（P＜0.01或P＜0.O01）。中年组和老年组比较，E峰和A／E比值差异无显著性，其余各指标差异有显著性（P＜0.05或P＜0.O01）。结论认为在左室肥厚早期，左室充盈功能降低，左房增大，左房代偿性收缩增强，向左室泵血增多，以维持恒定的房室压差弥补左室充盈不足，左室收缩功能可表现为正常；在LVH晚期，失代偿后左室收缩及舒张功能均降低。
Two-dimensional Doppler echocardiography was used to analyze hypertensive LVH and cardiac function in 36 middle-aged and 54 elderly patients. Results: LVH type in middle age group: Asymmetric interventricular septal hypertrophy (ASH) 40%, symmetry hypertrophy (CH) 46%. Dilation hypertrophy (DH) accounted for 14%; elderly group: ASH23%, CH26%, DH51%. Compared with the normal control group, there was no significant difference in the LVDd, LVV, EF and CO between the middle-aged group and the elderly group (P <0.01 or P <0.01) . There was no significant difference in E peak and A / E ratio between the middle-aged group and the elderly group, and there was a significant difference between the other indexes (P <0.05 or P <0.01). Conclusions: In the early stage of left ventricular hypertrophy, left ventricular filling function decreased, left atrium increased, left atrial compensatory contraction increased, increased left ventricular pumping to maintain a constant atrioventricular pressure to make up for lack of left ventricular filling, left ventricular Systolic function can be manifested as normal; late LVH, after decompensation, left ventricular systolic and diastolic function are reduced.
