原发性高血压716例治疗前后超声心动图检查结果对照研究

目的 探讨原发性高血压（高血压）患者治疗前后的超声心动图结果.方法 对东莞市寮步镇716例高血压患者进行强化治疗干预并行超声心动图检查,比较治疗前后的相关指标.结果 治疗干预后主动脉内径（26±4） mm vs.（28±4）mm,P＜0.05]及血流速度（1.06±0.28）m·s-1 vs.（1.12±0.26） m·s-1,P＜0.05]减小；二尖瓣E峰（0.66±0.22）m ·s-1 vs.（0.61±0.22）m·s-1,P＜0.05]、E/A比值（0.80±0.49vs.0.75±0.26,P＜0.05）、射血分数（69.9％±10.1％ vs.69.0％±11.2％,P＜0.05）、室壁缩短率（39.5％±8.8％vs.38.6％±9.5％,P＜0.05）增加；室壁厚度无明显改变.结论 高血压治疗明显改善患者的心脏功能.

Comparison of echocardiography results in 716 patients with hypertension before and after treatment

Objectives To compare the echocardiography results in patients with hypertension before and after treatment.Methods The study included 716 patients with hypertension in Liaobu town,Dongguan city.They were performed echocardiographic examination before and after treatment and the results were compared.Results After treatment,aortic dimension （26±4）mm vs.（28±4）mm,P〈0.05] and flow velocity （1.06±0.28）m ·s-1 vs.（1.12± 0.26）m·s-1,P〈0.05] decreased; peak E velocity at mitral valve （0.66±0.22）m·s-1 vs.（0.61±0.22）m·s-1,P〈0.05],E/A ratio （0.80±0.49 vs.0.75±0.26,P〈0.05）,ejection fraction （69.9%± 10.1% vs.69.0%± 11.2%,P〈0.05） and fractional shortening （39.5%±8.8% vs.38.6%±9.5%,P〈0.05） improved; ventricular wall thickness had no obvious difference.Conclusions Heart function can be improved in patients with hypertension after treatment.
