目的:应用应变率探讨不同左心室构型的原发性高血压患者左心室长轴方向应变－应变率成像的变化,及其与EF、FS及二尖瓣血流测量评价左室功能的对照研究。方法:采用M型、二维、多普勒超声及应变率成像技术,测量左室室壁厚度、左室内径、EF、FS,二尖瓣血流频谱E、A及左室平均应变ε,应变率S、e、a。结果:高血压离心性肥厚组EF、FS明显低于对照组,高血压其余各组EF、FS与对照组无统计学差异;收缩期应变率S应变ε在五组间差异均有显著性意义:高血压各组较正常对照组减小(I--Ⅴ呈递减);舒张期应变率e减低、a增高,e/a比值减小,各组间存在统计学差异(Plt;0.05); E/A,e/a结果大体一致。结论:应变率成像为临床提供了一个敏感、简便、可靠的评价原发性高血压患者左室心肌功能的指标。
摘要:目的:观察美托洛尔对高血压并慢性心衰(CHF)患者的心功能影响及临床疗效。方法:择高血压并高心病或冠心病60例,心功能Ⅱ～Ⅳ级的患者,随机分为两组,常规组(30例),给与控制血压、利尿、转换酶抑制剂(ACEI)、洋地黄治疗。美托洛尔组(30例),在常规治疗基础上加用美托洛尔。结果：美托洛尔组临床显效率(667%),总有效率(93.4%),较常规组显著提高(Plt;0.05)。美托洛尔组与常规组治疗前后,心率、血压、左室舒张末期直径、左室收缩末期直径、左室射血分数、心输出量、E/A、等容舒张期时间均有显著改善(美托洛尔组Plt;0.01,常规组Plt;0.05),且美托洛尔组上述指标改善更明显(Plt;0.01或Plt;0.05)。结论:美托洛尔显著改善高血压并慢性心力衰竭患者的心功能,是一种安全有效的治疗方法。Abstract: Objective: To observe US to hold Luo river to hypertension and the chronic heart failure (CHF) patient’s heart function influence and the clinical curative effect. Methods: Selects hypertension and the high worry or the coronary disease 60 examples, the heart functionⅡ~ⅣThe level patient, divides into two groups stochastically, the conventional group (30 examples), gives the control blood pressure, the diuresis, the transformation enzyme inhibitor (ACEI), the digitalis treatment. US holds Luo river Zu (30 examples), adds in the conventional treatment foundation with US holds Luo river. Results: US holds the Luo river group clinical obviously efficiency (66.7%), the total effectiveness (93.4%), compares the conventional group remarkable enhancement (Plt;0.05). Around US holds Luo river Zu and the conventional group treats, the heart rate, the blood pressure, the left room diastole last stage diameter, the left room contraction last stage diameter, the left room shoot the menstruation number, the cardiac output, E/A, the constant volume relaxing period time to have the remarkable improvement (US to hold Luo river ZuPlt;0.01, conventional group (P lt;0.05), and US holds the Luo river group above target improvement to be more obvious (Plt;001 or Plt;0.05). Conclusion: US holds Luo river obviously to improve hypertension and the chronic heart
