老年人单纯收缩期高血压 总被引:1,自引:0,他引:1
本文作者较系统地介绍了老年人单纯收缩期高血压的定义、诊断及处理意见。强调在监测心肌梗塞、中风和充血性心力衰竭方面,收缩压水平的意义与舒张压相似。为此,作者着重讨论了是否对单纯收缩期高血压给与治疗这一有争议的问题,并对老年人单纯收缩期高血压的治疗特点及效果作了评述。 相似文献

单纯收缩期高血压 总被引:13,自引:0,他引:13
单纯收缩期高血压(ISH)是老年人最常见的高血压类型,也是心血管(CV)并发症的主要危险因素,收缩压(SBP)和脉压(PP)增宽对CV事件有明显的预测价值,抗高血压治疗能改善ISH患者的预后,本文对ISH的流行病学情况,病理生理机制,SBP升高和PP增宽对心血管系统(CVS)的危害,治疗ISH使患者获益的有关临床研究等作了介绍.文章对利尿剂、钙拮抗剂(CCB)、血管紧张素Ⅱ受体拮抗剂(ARBs)、血管紧张素转换酶抑制剂(ACEI)和β受体阻滞剂(βB)等降压药物分别在ISH中的地位及联合用药等情况作了介绍和分析,也对ISH患者脉搏波有关指标变化情况和硝酸盐治疗ISH的意义和方法作了介绍. 相似文献

关节僵硬是老化的外在表征,这实在是一种折磨,让你活动速度减慢。或者不能做自己想做的事情。血管僵硬同样问题多多.它是血压随年龄增大而升高的主要元凶。你感觉不到高血压的存在,但它跟关节僵硬一样会降低你的活动能力,有时候是永久性地剥夺了你的活动能力。 相似文献

老年单纯收缩期高血压 (EISH)是冠心病脑卒中的独立危险因素之一〔1〕,药物治疗EISH可明显降低其所致的冠心病、脑卒中死亡率和残疾率〔2〕。老年人由于各脏器功能减退 ,内环境稳定性差 ,对药物耐受性、敏感性下降 ,使得EISH患者在抗高血压药物选择上受到诸多限制〔3〕。高血压是老年人常见的心血管病之一 ,收缩期高血压又是高血压中常见的类型 ,它的病因、发病机制、治疗及预后与经典的收缩压与舒张压同时升高有所不同 ,已成为当前老年高血压研究的一个重要课题〔4〕。1 EISH的有效治疗药物老年人可能对不同的药物都有效 ,但目前研… 相似文献

The pharmacological treatment, mainly based on diuretics, ofisolated systolic hypertension (ISH) has recently been shownto reduce the risk of stroke and coronary heart disease in theelderly. The purpose of this study was to compare the antithypertensiveeffect and tolerability of different drug regimens in elderlysubjects with ISH (systolic blood pressureSBP 160mmHg and diastolic blood pressure DBP <90mmHg). A multicentre, randomized, controlled open trial wasplanned in the general practice setting. Four widely used treatmentschedules were tested: hydrochlorothiazide 25 mg plus amiloride2·5 mg (H+Am), nifedipine slow release 20 mg (N), atenolol50 mg (At) and atenolol 25mg plus chlorthalidone 6·25mg (At+C). After a baseline evaluation, 308 patients (76·3% female,mean age 75·3 ± 7·1 years) were randomizedand followed up for 6 months. After 3 months the drug dosagewas doubled if the systolic blood pressure goal (SBP<160mmHg and SBP reduction of at least 20 mmHg) had not been reachedNinety-four subjects (30·5%) presented contraindicationsto ß-blockers. At the 3rd- and 6th-month visits alltreatment groups, except At, showed a significant reductionin SBP compared to the control group; DBP showed no significantreduction in any group at any time. At the end of the follow-upthe percentage of hypertensives who had reached the BP goalwas 14·6% in the control group, 52·9% in H+Am,54·8% in N, 28·6% in At and 52·2% in At+C.Over two-thirds of the patients on H+Am or N, and about 50%of those on At or At+ C at 6 months were taking the medicationat low dose. The rate of therapy discontinuation due to side effects duringfollow-up was significantly different among the drug regimenstested: 1·9% in the H+Am group compared to 12·5%,19·2% and 14·8% respectively in N, At and At+Cgroups (P<0·05 for H+Am vs At). The proportion ofsubjects who spontaneously reported, mild adverse effects after3 and 6 months of therapy was not signficantly different inthe study groups, even if an excess was observed in the N groupat 3 months. In conclusion, these data suggest that. diuretics are a firstchoice in the treatment of ISH, because of their hypotensiveefficacy and acceptability; nifedipine, if well tolerated, isan effective alternative to diuretics; a high proportion ofelderly patient with ISH present contraindications to ß-blockers,and atenolol has a poor antihypertensive effect. 相似文献

Isolated systolic hypertension (ISH) is a major risk factor for cardiovascular complications. Nevertheless, data on the prevalence in a representative population do not seem to be available. The prevalence of ISH and the white coat effect was thus studied in a cross-sectional survey of 2806 inhabitants aged 70-80 years. In untreated subjects, the prevalence of ISH was 17.4% (95% CI 14.9-20.2) in women and 13.5% (95% CI 11.3-15.9) in men using clinic blood pressure at first visit. The prevalence increased significantly with age. The prevalence was reduced to 10.4% when using the average of all-visits clinic blood pressures. By a simulation model, it was demonstrated that his reduction mainly resulted from a regression towards the mean. Average all-visits clinic blood pressure was 172.6 ±10.4/81.1±6.0 mmHg. Less than one-third of those with all-visit ISH had sustained ISH. Identifying subjects with sustained ISH requires measurements in more than three visits. 相似文献

BackgroundIsolated diastolic hypertension (IDH) is a largely unrecognized subtype of hypertension, more commonly seen in the younger age group.Aims(1) To determine the prevalence of IDH in the adult population of Kanpur district. (2) To study the associated risk factors of IDH.MethodsA community-based cross-sectional study was conducted in 801 subjects, aged 20 years and above, using multistage stratified random sampling technique.ResultsThe prevalence of IDH was 4.5%, which was 6.2% in men and 3.1% in women. A significant proportion of IDH was seen in the 40–49 years age group. Multivariate logistic regression analysis of the associated risk factors showed that gender, physical activity and BMI were significantly associated with IDH.ConclusionIsolated diastolic hypertension is an emerging problem in developing countries. IDH is more common among men, sedentary individuals and those with a higher BMI. 相似文献

BACKGROUND: With age, a larger proportion of elderly individuals have isolated systolic hypertension (ISH). However, because of a lack of longitudinal studies, much less is known about the incidence and prognosis of ISH in elderly individuals. The aims of this study were to document blood pressure (BP) trends in development of ISH in elderly individuals, and to investigate the incidence and prognosis for those with ISH. METHODS: Retrograde longitudinal analysis was conducted on 3284 subjects during 1958 to 1984. The presence of ISH in elderly individuals was defined as systolic BP of >or=160 and diastolic BP of or=60 years. Prognosis was subsequently investigated until 2002 and compared with that for age- and sex-matched non-ISH control subjects. RESULTS: Selected as ISH in elderly individuals were 185 subjects. Three subtypes were documented by BP trends: 71 subjects with "de novo" ISH, 68 with "burned out" ISH, and 46 subjects with "unclassifiable" ISH. Incidence of ISH increased with age. Mean onset age of ISH was 71.0 years. Subsequent follow-up revealed that the subjects with ISH lived long lives: 83.2% of ISH subjects and 76.2% of control subjects lived to be >80 years old. However, 58.9% of ISH subjects were found to have cardiovascular disease during the follow-up, showing a higher prevalence than among control subjects (42.2%, P = .0013). In more than 40% of subjects with ISH, cardiovascular disease occurred at >or=80 years of age. CONCLUSIONS: In this study, the incidence of ISH increased with age. Persons with ISH have good prognoses in terms of longevity, but many have late-onset cardiovascular complications, suggesting the importance of BP control even in very elderly individuals. 相似文献

目的 了解我国老年人群单纯性收缩期高血压的患病率及影响因素。方法 使用1991年全国高血压抽样调查资料 ,以≥ 6 0岁为老年人 ,单纯性收缩期高血压诊断标准按照 1999年WHO/ISH的规定 :收缩压≥ 14 0mmHg(1mmHg =0 133kPa)和舒张压 <90mmHg ,其亚型为收缩压 14 0~ 14 9mmHg和舒张压 <90mmHg ,分析患病率及其相关的影响因素。结果 (1)我国 6 0岁及以上人群单纯性收缩期高血压患病率为 2 1 5 0 % ,亚型患病率为 9 0 4 % ;如按收缩压≥ 16 0mmHg和舒张压 <90mmHg计算患病率则为 6 83%。 (2 )年龄增长是影响患病率最为明显的因素 ,35岁始患病率随年龄增长而显著升高 ;每增长 10岁患病率约增高一倍。性别差异则表明 35岁前男性患病率高于女性 ,但此后女性随年龄增长单纯性收缩期高血压上升幅度则高于男性。 (3)体重指数的大小与患病率成正比。结论 我国老年单纯性收缩期高血压患病率为 2 1 5 0 % ,占老年高血压总人数的5 3 2 1%。在老年高血压患者中防治单纯性收缩期高血压是降低人群高血压致死致残的重要组成部分。 相似文献
