老年人随着年龄的增长,内脏器官逐步老化,脏器功能也有了不同程度的衰退,因此老年人常有多脏器疾病,且彼此之间相互影响,使得临床表现的复杂多样。老年人心力衰竭的早期症状有着体征不典型,时常伴有着精神症状等特征,因此在诊断中极容易被误诊,漏诊,且治疗手段复杂棘手。本文结合老年心力衰竭患者临在临床上的治疗体会总结了老年心力衰竭患者的临床特点,以供同行治疗参考。 相似文献

The burden of disease in patients with congestive heart failure is high. The future of BNP looks promising as it may be a
better diagnostic tool for the diagnosis of CHF in developing countries in new millennium. Natriuretic peptide hormones, a
family of vasoactive peptides with many favourable physiological properties, have emerged as important contenders for development
of diagnostic tools and therapeutic agents in cardiovascular disease. Measurement of B-type natriuretic peptide has become
as an easy-to-perform bedside test. The clinical and diagnostic significance of the measurement of plasma Nt-proBNP in the
diseases of the cardiovascular system with particular emphasis on the assessment of patients with heart failure and their
effects on predicting survival rate. The plasma levels of Nt-proBrain Natriuretic peptide responds more vigorously after myocardial
infarction than those of other natriuretic peptides. This article is an attempt to give a short overview on the utility of
BNP-blood levels for the diagnosis and treatment of heart failure 相似文献

目的：为了解慢性肾衰竭（ CRF）患者的心脏损害情况,并探讨这种心脏损害的影响因素。方法：选择2012年一月至2013年1月收治的慢性肾衰竭30例患者作为观察组,另选同一时间段未患慢性肾衰竭30例患者作为对照组。将超声心动图检查两组患者的LAD,LAPWs,LAPWd,IVSTd,IVSTs, SV,EF等数据进行评价,分析慢性肾衰竭后患者心功能受损的情况。结果：检查后的两组数据显示,肾衰竭组LAD,LAPWs,LAPWd,IVSTd,IVSTs较对照组显著增加,具有患者心脏彩超异常者占93.3%（28/30）,具有统计学意义（p〈0.05）,观察组SV,EF,A,E较对照组明显增高,异常者为96.6%（29/30）。对照组心脏超声主要表为左室扩大、左室肥厚、左房扩大、瓣膜反流及心功能不全,尤以左室舒张功能损害为主。这些心脏损害的主要影响因素有尿毒症毒素、高血压、贫血。尽早透析,积极控制高血压,纠正贫血是预防和治疗CRF患者心脏并发症的主要手段。结论：对于肾衰竭患者而言,心脏彩超是一种无创性的较准确地反心脏形态和心功能受损的辅助检查方法。 相似文献

Although information systems (IS) success has been given much attention in IS literature, failure has received lesser attention. This study empirically validates a model of digital service failure for consumers by integrating three dimensions from Tan’s failure model and one dimension from DeLone and Mclean’s Information Success model. The factors have been mapped to Expectation Disconfirmation Theory (EDT). Experiential survey approach has been used to collect primary data from information systems users who have experienced digital service failure. Structural equation modeling (SEM) has been used for model testing and validation to measure the impact of information, system, functional and service failure of digital service on end users. The findings suggests that information, functional, system and service failure has an impact on the consumers through the outcome, process, cost and user satisfaction of digital services. 相似文献

永贞革新失败后,柳宗元一贬再贬,宦海沉浮,命运坎坷。谪居生活的悲凉与凄苦折磨着柳宗元,也造就了中国文学史上具有独特地位的山水游记名篇——《永州八记》。贬官后的柳宗元内心是极度痛苦的,为排遣苦闷,永州的山山水水成为他亲近与探访的对象。《小石潭记》就是在这种背景下写的。既然《小石潭记》的情感轴心是苦闷,那么怎样理解文中所写的＂乐＂呢？大自然特立独出的山水令作者冰释抑郁沉疴;柳宗元的＂乐＂不仅是暂时的,也是被动的;以乐写哀,哀更见其深,苦中作乐,苦更见其重。其实柳宗元完全应该感到快乐：其一,永贞革新具有历史进步性;其二,柳宗元的坎坷经历造就了山水精品——《永州八记》。 相似文献

目的:观察参附注射液联合西药治疗急性左心衰竭(Acute heart failure,AHF)的临床疗效。方法:选择AHF患者150例,随机分为对照组和治疗组,对照组给予单纯西药治疗,治疗组在对照组用药的基础上加用参附注射液50ml/d静滴。疗程为10天。结果:治疗组总有效率93.3%,明显高于对照组(P0.05)。两组疗后肺部湿啰音均明显减少,而经疗后的组间比较,治疗组的中医证候积分、脑钠肽和左室射血分数改善更显著(P0.05),结论:参附注射液联合西药治疗AHF的疗效比单用西药疗效更佳,值得在临床上推广应用。 相似文献

Background
In heart failure patients, mean platelet volume (MPV) may reflect increased platelet activation or increased numbers of large, hyper-aggregable platelets. B-type natriuretic peptide (BNP) concentration in blood is a sensitive and specific marker of heart failure, correlating with the severity and prognosis of illness, in patients presenting with acute dyspnea to the emergency department. This study evaluated the correlation between BNP concentration and MPV.Material and methods
Data were collected from 319 patients admitted to the emergency department of a cardiology hospital from January–July 2014. EDTA blood samples drawn at admission were analyzed using automated hematology system, and BNP concentration was measured using a fluorescence immunoassay.Results
The study included 190 patients with and 129 without acute heart failure (AHF). These groups had BNP concentration of 200-5000 ng/L and 5-98 ng/L, respectively. MPV levels were significantly higher in the AHF group (P < 0.001). BNP concentrations were positively correlated with MPV (r = 0.41, P < 0.001) and neutrophil / lymphocyte ratio (r = 0.38, P < 0.001).Conclusion
Increased MPV values correlate with BNP concentration, an indicator of HF severity and clinical status, in patients with AHF admitted to the emergency department.Key words: natriuretic peptide, brain; heart failure; platelet; mean platelet volume 相似文献18.
[目的/意义]现有研究大多是从服务成功的视角展开分析,尚未对服务失败进行深入讨论,认识上的不足会阻碍实践的提升。该研究旨在透过对失败成因与影响的探究,丰富现有认识,为实践提供参考。[方法/过程]通过整合信息系统成功模型与电子商务服务失败模型,将在线政务服务失败的成因划分为信息失败、功能失败、系统失败和服务失败;借助期望不一致理论和“退出-呼吁-忠诚”理论,建立了“成因-期望-行为”为逻辑主线的理论模型。使用问卷收集数据,运用软件Smart PLS进行路径分析,对研究假设进行检验。[结果/结论]研究发现:信息、功能、系统和服务四个因素可以很好的解释在线政务服务失败;结果期望不一致、过程期望不一致对退出行为、呼吁行为具有显著影响,但不会对接受行为产生作用;成本期望不一致对这三类行为都会产生显著影响;信息失败、功能失败、系统失败和服务失败对用户行为发挥着不同的作用。 相似文献

学困生的形成有着复杂的因素,除学生自身因素外．还有学科、地域、社会、家庭、学校等外部条件。这些学生大多学习态度消极、基础水平低,平时没有养成良好的学习习惯及浓厚的学习兴趣．导致在学习的过程中反复失败,最终造成其自信心和学习积极性严重受挫。久而久之,开始厌恶学习、惧怕学习、抵触学习并以消极的态度对待学习 相似文献
