左室肥厚(LVH)是心肌组织的肥厚,是心脏对长期动脉高压适应的结果,LVH病人猝死、急性心肌梗塞、心衰、心律失常、脑卒中等心血管病的发生率比正常心脏要高几倍.因此LVH较血压对预后的估计有重要意义.笔者观察到长期应用培它乐克(betoloc)对逆转左室肥厚有重要影响,报告如下.1对象与方法1.1 对象1992年1月～1994年1月从门诊及住院的老年高血压病人中选择合并LVH者68例.根据1978年WHO诊断高血压的标准诊断为高血压Ⅱ期者,且所有的受试者经病史、体检、实验室检查、心电图检查(包括运动试验)及超声心动图等排除继发性高血压、冠心病、心肌病、糖尿病及其它器质性心脏病.LVH均经超声心动图确定诊断.男性52例,女性16例,年龄60～88岁.平均68.2岁,病程4～30年,平均13.6年.用抽签法随机分二组,服用培它乐克组38例,对照组30例,两组年
Left ventricular hypertrophy (LVH) is the hypertrophy of myocardial tissue and is the result of adaptation of the heart to long-term arterial hypertension. The incidence of cardiovascular diseases such as sudden death, acute myocardial infarction, heart failure, arrhythmia, stroke and so on is higher in patients with LVH than in normal heart Several times.Therefore, LVH than blood pressure on the prognosis of the prognostic significance.I observed that long-term use of peraceticide (betoloc) on the reverse left ventricular hypertrophy have an important impact, the report is as follows.1 objects and methods 1.1 object January 1992 ~ January 1994 outpatients and hospitalized elderly patients with hypertension selected LVH in 68 cases.According to the WHO diagnostic criteria for hypertension in 1978 was stage Ⅱ hypertension, and all the subjects by history, physical examination, experiment Room examination, ECG examination (including exercise test) and echocardiography to exclude secondary hypertension, coronary heart disease, cardiomyopathy, diabetes and other organic heart disease.LVH were confirmed by echocardiography diagnosis.A total of 52 males, 16 females, aged 60 to 88 years, mean 68.2 years, duration of 4 to 30 years, an average of 13.6 years by random selection of two groups drawn by lottery, taking 38 cases of peracetic, 30 cases of control group, two groups of years
