The relationships of coronary heart disease (CHD) defined by coronaryarteriography (CAG) and risk factors or the levels of ones were studied in 141CHD cases, 127 hospital-based and 127 population-based non-CHD controls.By stratification and multivariate analyses, it were found that hypertension,hypercholesterolemia, smoking, type-A behavior pattern, family diseaseshistory and large intake of animal fat are the risk factors of CHD; physicalexercise and intake of bean products are protective factors.

The relationships of coronary heart disease (CHD) defined by coronaryarteriography (CAG) and risk factors or the levels of ones were studied in 141CHD cases, 127 hospital-based and 127 population-based non-CHD controls.By stratification and multivariate analyses, it were found that hypertension,hypercholesterolemia, smoking, type-A behavior pattern, family diseaseshistory and large intake of animal fat are the risk factors of CHD; physicalexercise and intake of bean products are protective factors. The synergiceffect of risk factors (e.g. hypertension, hypercholesterolemia and smoking)were similar to the model of multiplication. There were sure significantpositive correlations between the levels of some risk factors and the degreeof coronary atherosclerosis.

在141例冠脉造影确诊的冠心病者和127例医院对照及127例人群对照中进行了冠心病危险因素的病例对照研究。经分层和多元统计分析表明:高血压、高血脂、吸咽、A型性格、家族病史和动物脂肪摄入较多是冠心病的危险因素;而体育锻炼和食用豆制品是保护因素。高血压、高血脂和吸烟三个主要危险因素间的相互作用关系近似符合相乘模型。危险因素水平与冠脉粥样硬化程度间有明确的剂量反应关系。

One hundred and twenty-six rural hypertensive patients with ECG left ventricular hypertrophy(HT-LVH)were followed up for 10 years to investigate the prognostic characteristics in a population with low prevalence of hypertension(2.93%)and low plasma cholesterol (4.59±1.00mmol/L).A cohort of age, sex,region and occupation matched hypertensives without LVH(HT,n=163) and normotensives(NT, n=275)served as controls. The major cause of death in rural hypertensives with ECG LVH in this study was stroke(56.8%). After...

One hundred and twenty-six rural hypertensive patients with ECG left ventricular hypertrophy(HT-LVH)were followed up for 10 years to investigate the prognostic characteristics in a population with low prevalence of hypertension(2.93%)and low plasma cholesterol (4.59±1.00mmol/L).A cohort of age, sex,region and occupation matched hypertensives without LVH(HT,n=163) and normotensives(NT, n=275)served as controls. The major cause of death in rural hypertensives with ECG LVH in this study was stroke(56.8%). After stratification of BP,no significant difference of stroke risk was found between patients with LVH and hypertensives without LVH , while cardiovascular risk in the patients with LVH plus ST segment depression persisted. LVH per se seems not to be an independent factor for stroke, The high stroke rate in patients with LVH may be ascribed to the coexisting higher level of BP. After adjustment of coexisting hypertension, ECG LVH based on voltage only was not an independent risk factor of stroke and cardiovascular events,while LVH plus ST segment depression was closely related to cardiovascular events.In this low level, plasma cholesterol did not affect the mortality rate of stroke.

对126例中国农村高血压合并左心室肥厚(HT-LVH)患者追踪观察10年,并以年龄、性别、职业和地区相匹配的163例单纯高血压(HT)与275例正常人做为非暴露组,进行队列研究。结果发现我国农村HT-LVH患者死亡原因虽以脑卒中居多,但矫正血压因素后,LVH本身并非脑卒中独立危险因子,然仍为心血管意外的独立危险因子。LVH所以合并脑卒中较多,是由于其血压均值在3组中最高的缘故。矫正血压因素后,心电图单纯左心室高电压的脑卒中与心血管意外危险因素都消失,只有左心室肥厚加劳损才是心血管意外的独立危险因素。建议不必把左心室高电压列为心、脑血管意外的危险因子。在低水平范围内,血胆固醇的高低对脑卒中意外发生率无影响。

Objective To assess the predictive values of 4 noninvasive tests for risk stratification of sudden cardiac death (SCD) after myocardial infarction (MI). Methods The 79 elderly patients with previous were divided into two groups. The SCD group was composed of 22 MI patients who died suddenly within one hour after onset of symptoms. The nonSCD group comprised of 57 MI patients survived. The results of the following 4 noninvasive test in the 2 groups were compared. Results (1)LVEF and HRVI were...

Objective To assess the predictive values of 4 noninvasive tests for risk stratification of sudden cardiac death (SCD) after myocardial infarction (MI). Methods The 79 elderly patients with previous were divided into two groups. The SCD group was composed of 22 MI patients who died suddenly within one hour after onset of symptoms. The nonSCD group comprised of 57 MI patients survived. The results of the following 4 noninvasive test in the 2 groups were compared. Results (1)LVEF and HRVI were significantly lower in the SCD group than those in the nonSCD group (P<001), whereas QT dispersion and incidence of VPBs>30/h were not significantly different between the two groups. (2) LVEF was ranked as the best independent predictor for the risk of sudden cardiac death after MI on multifactorial logistic regression analysis. (3)Using LVEF 45% as a cutting point, the incidence of VPBs>30/h was obviously higher (P<001) and HRVI was lower (P<005) in the subgroup with LVEF<45% compared with the subgroup with LVEF>45%. Conclusions The elderly patients with left ventricular dysfunction after myocardial infarction are susceptible to more serious dysfunction of cardiac autonomic nervous system and malignant ventricular arrythmias, causing sudden cardiac death. LVEF is an important index for risk stratification of sudden cardiac death in such elderly patients.

目的探讨4项非创伤性检查指标对老年人陈旧性心肌梗死后心性猝死危险性的预测价值。方法老年人陈旧性心肌梗死79例,分为猝死组(22例)和非猝死组(57例),对比分析两组间4项指标的差异。结果(1)猝死组的左室射血分数(LVEF)和心率变异性指数(HRVI)明显低于非猝死组(P<0.01),而QT离散度和24小时动态心电图室性期前收缩(VPBs)>30个/小时的发生率在两组间差异无显著性。(2)Logistic多因素回归分析显示LVEF是预测心性猝死危险性的独立指标。如以LVEF45%为界分组,LVEF<45%组的VPBs>30个/小时的发生率明显高于LVEF>45%组(P<0.01),HRVI明显低于LVEF>45%组(P<0.05)。结论老年人心肌梗死伴左心功能不全者易发生心脏自主神经功能失调,诱发严重室性心律失常,导致心性猝死。
