摘要
目的:评估肾功能异常对恶性高血压患者心脏结构与功能的影响。方法:恶性高血压患者根据肾功能分为肾功能正常组(31例)和肾功能异常组(32例),测量左心室重量(LVM)、重量指数(LVMI)、左室舒张末内径(LVEDd)、室间隔厚度(IVST)、相对室壁厚度(RWT)左室后壁厚度(LVPWT)以及左心室舒张早期二尖瓣最大血流速度(E峰)与舒张晚期二尖瓣最大血流速度(A峰)、E/A比值和左室射血分数(LVEF)等心脏功能指标。结果:与肾功能正常组比较,肾功能不全组IVST[(11.6±1.9)mm比(13.0±2.0)mm]、LVPWT[(10.6±1.9)mm比(12.7±1.4)mm]、LVEDd[(48.4±6.6)mm比(52.5±3.9)mm]、RWT[(0.44±0.08)mm比(0.51±0.07)mm]、LVM[(208.1±77.5)g比(264.2±63.1)g]、LVMI[(114.5±39.2)g/m2比(152.6±39.0)g/m2],左室肥厚比例(25.0%比85.7%)明显增加(P<0.05),而LVEF、E/A差异则无显著性(P>0.05)。结论:肾功能不全患者左心室肥厚较肾功能正常患者更加明显,而收缩、舒张功能指标改变差别不显著。
Objective: To assess influence of abnormal renal function on cardiac structure and function in patients with malignant hypertension (MH). Methods: According to renal function, a total of 63 MH patients were divided into normal renal function group (n = 31) and abnormal renal function group (n = 32). Left ventricular mass (LVM), left ventricular mass index (LVMI), left ventricular end-diastolic dimension (LVEDd), interventricular septal thickness (IVST), relative wall thickness (RWT), left ventricular posterior wall thickness (LVPWT), left ventricular early diastolic (E), late diastolic (A) mitral valve peak flow velocity, E/A and left ventricular ejection fraction (LVEF) were measured. Results: Compared with normal renal function group, there were significant in- creasein IVST [ (11.6±1.9) mmvs. (13.0±2.0) mm], LVPWT [ (10.6±1.9) mmvs. (12.7±1.4) mm], LVEDd [ (48. 4±6.6) mmvs. (52.5±3.9) mm], RWT [ (0.44±0.08) mm vs. (0.51±0.07) mm], LVM [ (208.1 ± 77. 5) g vs. (264.2± 63.1) g], LVMI [ (114.5±39.2) g/m2vs. (152.6±39.0) g/m2], and percent- age of left ventricular hypertrophy (25.0% vs. 85.7%) in abnormal renal function group, P〈0.05 all; There were no significant difference in LVEF and E/A between two groups (P〈0.05). Conclusion: Left ventricular hy- pertrophy in patients with renal insufficiency is more significant than that of those with normal renal function, butdifferences of indexes of systolic and diastolic function were no significant.
