重视抵抗性高血压管理

由于诸多因素,使得一些高血压患者对治疗产生抵抗,或表现为难治性,其中有疾病因素、对治疗的依从性、其他药物的干扰和生活方式等.研究已经证明,有效地控制血压,使之达标,可以有效地降低重要靶器官受损的危险性.而规范、系统地控制血压、加强对抵抗性高血压的管理是保护靶器官的重要途径,同时需要进一步的研究证据的支持.     

高血压联合用药与靶器官保护

高血压是造成心血管疾病最重要的可逆性危险因素之一,但大多数患者仍未采取合适治疗,或未达到合适的血压控制目标。循证医学证实,联合使用降压药物不仅是控制血压达标的主要手段,而且是保护靶器官的重要措施,可明显减少心、脑、肾等重要靶器官损害,降低心血管疾病的发病率、病死率和致残率。高血压的联合用药应得到高度重视。

高血压合并糖尿病患者的降压目标及治疗

高血压合并糖尿病是冠心病致死的危险因素。有效地控制血压可以显著地降低糖尿病病人心血管事件的发病率与病死率。高血压糖尿病病人的血压控制目标为〈130／80mmHg。为了达到这一血压水平,糖尿病病人的降压治疗包括合理的非药物治疗与药物治疗。在药物治疗中应选用血管紧张素转换酶抑制剂、血管紧张素受体拮抗剂、钙离子拮抗剂和小剂量利尿剂,并且注意联合用药。     

老年高血压降压药物的选择

随着社会进入老龄化,我国老年高血压的绝对人数逐渐上升,目前我国60岁以上人群高血压的患病率为49％,80岁以上人群高血压的患病率为90％.高血压对于老年人的危害更为严重,老年高血压患者发生靶器官损害以及相关死亡的危险性显著增高,故合理地控制老年患者的血压,对于降低病死率,改善生活质量有着重要的意义.但老年高血压有其特殊的病理生理及临床特点,要求我们在治疗药物的选择上要兼顾多方面因素,合理用药,减少副作用,降低病死率.     

降压达标在高血压治疗中的意义

随着高血压发病人数的增加,高血压所造成的心、脑、肾等重要靶器官损伤、功能衰竭日益受到重视。临床研究证明,为减少由高血压造成的重要器官损伤、提高患者的生活质量、降低病死率,通过各种方式尽快将血压控制在所要求的达标范围内是非常必要的。     

个体化降压的临床意义

高血压是由多种病因和发病机制引起的一种慢性疾病,可以导致多种靶器官功能损害,并最终导致严重的心、脑血管并发症,危及人类的健康和生命。如何做到有效的预防和治疗是目前面,临的问题。本文分析了高血压控制的现状,以矛盾的特殊性原理为指导,从高血压的病因和发病机制、临床特点以及药物对个体的敏感性等诸多方面出发,阐述了高血压患者个体差异性。高血压患者个体差异性决定每一个个体综合控制策略的不同,运用“具体问题具体分析”的方法,为每一个个体制定个体化的血压控制方案,以期达到理想的高血压整体控制水平。

降压达标治疗中的个体化原则与优化治疗

为了提高高血压患者的降压达标率、最大程度地降低靶器官损伤,一方面应强化生活方式的改变,包括戒烟限酒、低盐饮食、减轻体重和适量运动,另一方面,由于原发性高血压的发病是由多种复杂因素的不同组合引起,应根据不同个体的高血压发病机制及病因的差异,在指南的指导下,应用不同种类抗高血压药物(单用或联合用药),采用针对个体的优化治疗,才能更有效地使降压治疗达标。

老年高血压降压不易达标及降压质量低的原因分析及对策

老年高血压降压不易达标或降压质量低,原因在于老年高血压的特殊性,如多发收缩期高血压、血压波动大、易发生体位性低血压、合并多脏器功能损害等。在老年高血压的治疗中,应充分认识其特殊性,开展健康教育、改善生活方式,正确选择降压药,在降压达标治疗的基础上,提高降压质量,最大限度降低患者靶器官损害,减少心血管终点事件的发生。     

血压的生物节律与高血压的时间治疗学

人体血压的昼夜节律现象具有重要临床意义,高血压病更尤为如此。不同降压药物或不同时间用药对血压的昼夜节律产生不同的影响。高血压时间治疗学是根据疾病发生或发作的昼夜节律特征,通过调整投药时间及/或剂量、或应用特殊制剂,调整血液或组织中的药物浓度,从而增加疗效并减少或避免不良反应的发生。时间治疗学方法有助于以最小的医疗经济学及毒副反应代价获取最佳的治疗效果。     

Age-related effects of blood pressure on everyday cognitive function in community-dwelling women

ABSTRACT

Objectives: Blood pressure is an indicator of vascular health that has been associated with cognition and quality of life in older age. Few studies have examined blood pressure across everyday cognitive tasks, which may have superior predictive functional utility than traditional cognitive measures. We explored blood pressure as a predictor of everyday problem solving (EPS) performance in middle-aged and older women. Method: Community-dwelling women (age: 51–91) with low-normal blood pressure to mild hypertension underwent traditional and everyday cognitive testing. EPS was determined by the number of safe/effective solutions generated for real-world scenarios. Results: Analyses revealed that lower systolic blood pressure and pulse pressure were associated with worse EPS ability after controlling for age, education, and traditional cognitive abilities. Discussion: These results support that blood pressure may be an important predictor of everyday cognitive abilities in older age. Potential implications for real-world functioning are discussed.     

降压治疗的决策思考

尽管降压药物有了很大发展,高血压的控制率仍很低下。降压治疗中还存在包括医生和患者两方面的许多误区。目前已取得的共识是:降压治疗的益处主要来自血压控制。因此,非常重要的是要达到血压的有效和长期稳定的降低。根据患者的年龄、基线血压、伴随的临床状况等,因人而异地选择副作用小、降压效果好的药物,提高顺应性是改善高血压控制率的关键。     

Psychological factors associated with poor hypertension control: differences in personality and stress between patients with controlled and uncontrolled hypertension

Only one-third of patients with hypertension under pharmacological treatment achieve the recommended blood pressure goals. Psychological factors could partially account for poor hypertension control through the existence of personality traits related to treatment compliance (e.g., self-discipline, deliberation, impulsiveness), and the fact that stress and some personality traits (e.g., anxiety, depression, anger expression, Type A) are involved in the etiology of some hypertension cases. This study was aimed at examining the differences in personality and stress between patients taking antihypertensive medications with controlled and uncontrolled hypertension. Results revealed that after controlling sex, age, and traditional variables associated with poor hypertension control, the uncontrolled hypertension group showed higher scores on impulsiveness, depression, anger expression-out, and stress, with differences ranging between medium and large (Hedges' g effect size = 0.77 to 1.08). These results support the hypothesized relationship between psychological factors and poor hypertension control.     

Does anxiety or cardiovascular reactivity have a causal role in hypertension?

Anxiety, stress, and cardiovascular reactivity (CVR) are variously believed to play a role in sustained hypertension. Although acute anxiety or stress elicits acute pressor responses, there is little support for their significant role in sustained hypertension. Anxiety correlates poorly with CVR, and blood pressure levels and anxiolytics do not sustain blood pressure lowering in subjects with hypertension-associated anxiety. Chronic anxiety disorders tend to be characterized by relatively low blood pressure and prevalence of sustained hypertension. Blood Pressure Regulation in hypertension is normal, and normo- and hypertensives have similar ambulatory blood pressure variability. Laboratory CVR fails to predict variability in natural environments, hyperreactors do not exhibit increased variability in natural environments, and the increased variability and ambulatory reactivity that is "accounted for" by laboratory responses is small. These findings do not support the belief that hypertension is related to a summation of heightened pressor responses over time. Antihypertensives normalize elevated blood pressures but do not alter CVR in the laboratory or variability in natural environments, probably because of a dual central regulation of resting and reactive blood pressures. Psychological stress responses result from selective neuronal activation rather than from generalized sympathetic neural responses or dysregulation. Differences in blood pressure responses during various emotions are only quantitative, with no specificity of sympathoadrenal or emotional responses to stressors. It may be time to regard reactive cardiovascular responses as physiological, rather than as psychological, and to require much stronger evidence to confirm causal roles of anxiety, stress, and reactivity in sustained hypertension.
