目的 探索老年性高血压病心血管结构及血流动力学改变及其临床意义。 方法 根据WHO/ISH高血压治疗指南高血压定义标准,应用美国AU 4超声诊断仪,2 .5～3 .5MHz环阵扇扫探头对3 0例具有明显阳性体征的原发性高血压病人(观察组)和3 0例没有阳性体征的原发性高血压病人(对照组)进行研究,作对比分析。 结果 观察组主动脉瓣返流10 0 % ,二尖瓣返流46.6% ,三尖瓣返流2 3 .3 % ,肺动脉瓣返流6.7%。观察组二尖瓣A峰增高,肺动脉血流减低,主动脉血流增高,与对照组比较有显著性差异(P <0 .0 5 )。观察组左心结构及功能均有明显的改变。 结论 对老年性高血压病患者行常规2D -DE -CDFI超声心动图检查,对患者病情判定、预后估计、治疗方式和时机的选择都具有极为重要的意义
Objective To explore the changes of cardiovascular structure and hemodynamics in senile essential hypertension and its clinical significance. Methods According to the definition of hypertension in WHO / ISH guidelines, 30 cases of patients with essential hypertension with obvious positive signs were screened by the US AU 4 ultrasonic diagnostic apparatus and 2.5 ~ 3.5MHz circular array scanners Observation group) and 30 patients with no primary signs of hypertension (control group) were studied for comparative analysis. Results In the observation group, aortic valve regurgitation was 100%, mitral regurgitation was 46.6%, tricuspid regurgitation was 23.3% and pulmonary valve regurgitation was 6.7%. In the observation group, the peak A of mitral valve increased, the pulmonary blood flow decreased and the aortic blood flow increased, which was significantly different from the control group (P <0.05). Observation group left heart structure and function were significantly changed. Conclusion Conventional 2D-DE-CDFI echocardiography in senile patients with essential hypertension is very important for the determination of patients’ condition, estimation of prognosis, choice of treatment methods and timing
