目的 应用回声追踪技术评价原发性高血压颈动脉粥样硬化与左心室重构之间的相关性.方法 选取原发性高血压患者90例,所有患者均经过颈动脉彩色多普勒超声检查并除外颈动脉斑块形成.应用彩色多普勒超声心动图测量左心室舒张末期内径(LVEDd)、左心室收缩末期内径(LVEDs)、左心室后壁厚度(LVPW)、室间隔厚度(IVS),计算左心室心肌重量指数(LVMI).根据LVMI将所有患者分为左心室肥厚(LVH)组(31例)与非左心室肥厚(NLVH)组(59例).应用回声追踪技术测量患者颈动脉压力应变弹性系数(Ep)、硬化度、顺应性、膨大系数、脉搏波传导速度(PWV),并与LVMI进行相关性分析.结果 高血压LVH组的颈动脉硬化度、Ep与PWVβ明显高于高血压NLVH组,而颈动脉顺应性明显低于高血压NLVH组,且差异均有统计学意义[(10.00±3.40)比(7.23±1.28),(141.30±43.60) kPa比(110.90 ±35.10) kPa,(8.20±2.60) m/s比(6.05±0.78) m/s,(0.52±0.33) mm2/kPa比(0.85±0.41) mm2/kPa] (P＜0.05).LVMI与硬化度、Ep呈明显正相关(r=0.683,0.556,P＜0.05),与顺应性呈明显负相关(r=-0.706,P＜0.05).结论 高血压患者的左心室重构与颈动脉硬化度、Ep、顺应性具有明显的相关性,应用颈动脉回声追踪技术参数能很好地评价高血压患者靶器官损害的程度,具有较高的临床意义.
目的 應用迴聲追蹤技術評價原髮性高血壓頸動脈粥樣硬化與左心室重構之間的相關性.方法 選取原髮性高血壓患者90例,所有患者均經過頸動脈綵色多普勒超聲檢查併除外頸動脈斑塊形成.應用綵色多普勒超聲心動圖測量左心室舒張末期內徑(LVEDd)、左心室收縮末期內徑(LVEDs)、左心室後壁厚度(LVPW)、室間隔厚度(IVS),計算左心室心肌重量指數(LVMI).根據LVMI將所有患者分為左心室肥厚(LVH)組(31例)與非左心室肥厚(NLVH)組(59例).應用迴聲追蹤技術測量患者頸動脈壓力應變彈性繫數(Ep)、硬化度、順應性、膨大繫數、脈搏波傳導速度(PWV),併與LVMI進行相關性分析.結果 高血壓LVH組的頸動脈硬化度、Ep與PWVβ明顯高于高血壓NLVH組,而頸動脈順應性明顯低于高血壓NLVH組,且差異均有統計學意義[(10.00±3.40)比(7.23±1.28),(141.30±43.60) kPa比(110.90 ±35.10) kPa,(8.20±2.60) m/s比(6.05±0.78) m/s,(0.52±0.33) mm2/kPa比(0.85±0.41) mm2/kPa] (P＜0.05).LVMI與硬化度、Ep呈明顯正相關(r=0.683,0.556,P＜0.05),與順應性呈明顯負相關(r=-0.706,P＜0.05).結論 高血壓患者的左心室重構與頸動脈硬化度、Ep、順應性具有明顯的相關性,應用頸動脈迴聲追蹤技術參數能很好地評價高血壓患者靶器官損害的程度,具有較高的臨床意義.

Objective To investigate the relation between carotid atherosclerosis and left ventricular remodeling in essential hypertension patients using the echo tracking technique.Methods Totally 90 essential hypertension patients were enrolled in this study.No patients had carotid plaques.Echocardiography was performed.Left ventricular end-diastolic diameter (LVEDd),left ventricular end-systolic diameter (LVEDs),left ventricular posterior wall thickness (LVPW) and interventricular septum thickness (IVS) were measured and left ventricular myocardial weight index (LVMI) was calculated.Patients were divided into two groups based on LVMI:patients with left ventricular hypertrophy (LVH group,31 cases) and patients without left ventricular hypertrophy (NLYH group,59 cases).Echo tracking imaging was performed to evaluate the carotid arteriosclerosis of the patients and the following parameters were measured:coefficient of elastic (Ep),hardening degree (β),compliance (AC),enlargement coefficient (AI),pulse wave conduction velocity (PWVβ).Results There were significant differences in β,Ep,AC and PWVβ between patients with left ventricular hypertrophy and patients without left ventricular hypertrophy (P ＜ 0.05).LVMI was highly dependent on β,Ep and AC (r =0.683,0.556,-0.706 respectively,P ＜ 0.05).Conclusions Left ventricular remodeling is significantly correlated with carotid atherosclerosis in essential hypertension patients.Echo tracking technique is valuable in evaluation of organ damage for essential hypertension patients.
