目的：探讨超声心动图（UCG）对高血压性心脏病（HHD）患者左心房结构及功能的诊断价值，为早期诊断和治疗提供依据。方法选取 HHD 患者50例作为观察组，同期体检的健康人群50例作为对照组，采用Philips Sonos 5500型彩超仪，探头频率2.0~4.0 MHz，检测左室射血分数（LVEF）、收缩末期容积（LVESV）、舒张末期容积（LVEDV）、心肌质量（LVMM）、二尖瓣口舒张末期血流速度 E 峰与 A 峰比值、左心房内径（LAD）等指标。结果左心收缩功能组间比较差异无统计学意义（P >0.05）；LVEDV、LVMM、LAD 观察组高于对照组，差异有统计学意义（P <0.05）；E/ A、LVEF 观察组低于对照组，差异有统计学意义（P <0.05）。观察组组内比较，LVEDV、LVD、LVEF、E/ A：Ⅲ期>Ⅱ期>Ⅰ期。LVEDV、LVD 与血压值呈正相关，E/ A、LVEF 与血压值呈负相关。结论 UCG 能够直接准确确定左心房增大的面积或左心室肥厚的程度，客观评价心脏功能，为 HHD 的早期诊断、治疗及预后评估提供依据。

Objective To investigate the diagnostic value of left ventricular structure and func-tion on patients with hypertensive heart disease(HHD)by ultrasonic cardiography(UCG),in order to provide the basis for early diagnosis and treatment. Methods Fifty patients with HHD were chose as ob-servation group,and 50 healthy people as control group. Using Philips Sonos 5500 ultrasound apparatus, the transducer frequency was 2. 0 - 4. 0 MHz,the left ventricular ejection fraction(LVEF),left ventric-ular end systolic volume(LVESV),left ventricular end-diastolic volume(LVEDV),left ventricular my-ocardial quality(LVMM),the ratio of E peak and A peak of mitral orifice end diastolic velocity,the left atrium diameter(LAD),and other indicators were detected. Results The difference of left cardiac sys-tolic function between the two groups was not significant(P > 0. 05);LVEDV,LVMM,LAD in observa-tion group was higher than that in control group,the difference was significant(P < 0. 05);E / A,LVEF in observation group was lower than that in control group,the difference was statistically significant(P <0. 05). In observation group,LVEDV,LVD,LVEF,E / A showed Ⅲ period > Ⅱ period > Ⅰ period. LVEDV,LVD was positively correlated with blood pressure value,E / A,LVEF was negatively correlated with blood pressure values. Conclusions UCG can accurately determine the area of the left atrial en-largement or the degree of left ventricular hypertrophy,objective evaluation of cardiac function,and pro-vide a basis for early diagnosis,treatment and prognosis evaluation of HHD.
