| 目的：本研究利用超声心动图检测高血压心室肥厚患者左心房结构，探讨当左心结构发生变化时心脏功能所受到的影响，
为高血压及其并发症的临床诊断提供检测及诊断参考。方法：选取2011年5 月-2013 年1 月在我院接受检查的高血压心室肥厚
患者76 例作为观察组，另选取同期经体检的健康人群60 例为健康对照组，利用超声心动图观察左心功能和结构，比较两组研究
对象的左心房内径(LAD)、心肌质量(LVMM)、舒张末容积(LVEDV)、收缩末容积(LVESV)、左心室射血分数(LVEF)及二尖瓣口舒
张末期流速比值(E/A)。结果：两组间心室收缩功能无显著性差异(P>0.05)；高血压组LAD 高于对照组，LVEF及E/A 低于对照组，
差异具有统计学意义(P<0.05)；高血压Ⅰ 期、Ⅱ 期、Ⅲ 期患者间比较，左房内径随血压的升高逐渐递增，而左心室射血分数和二尖
瓣口舒张期流速比值则逐渐递减，差异具有统计学意义(P<0.05)。结论：超声心动图可以直观的显示高血压心室肥厚患者左心功
能及血流动力学的变化，对临床诊断具有积极的意义。 |

| Objective:To discuss the functions of heart through the inspection of the changes in the left atrial structure of patients
with hypertension by means of the ultrasonic cardiogram so as to provide some references for the clinical diagnosis.Methods:Sixty
patients with hypertensive heart disease who were treated in our hospital from May 2011 to January 2013 were selected as the
observation group, and another sixty healthy people who were inspected in our hospital at the same time were chosen to be the control
group. Then the structure and function of left heart were detected by UCG, and the left atrium diameter (LAD), myocardial quality
(LVMM), end-diastolic volume(LVEDV), end-systolic volume(LVESV), left ventricular ejection fraction(LVEF) and the ratio of mitral
diastolic velocity (E/A) were observed and compared between two groups.Results:There was no statistically significant difference about
the ventricular systolic function between two groups (P>0.05). The LAD of patients in the observation group was higher than that of the
patients in the control group, while the LVEF and E/A were lower than those of the patients in the control group with statistically
significants(P<0.05). With the increasing of blood pressure, the LAD increased while the LVEF and E/A decreased among the patients in
the three stages of hypertension with statistically significant differences (P<0.05).Conclusion:It is suggested that the ultrasonic
cardiogramshould be significant to the clinical diagnosis by presenting the data intuitively. |
