Abstract

BACKGROUND:Despite readily available treatments, control of blood pressure (BP) with population aging remains suboptimal. Further, there are gaps in the understanding of the management of high BP in the aged. We explored antihypertensive treatment and control among elderly hypertensive participants free from overt cardiovascular disease (CVD), and identified factors related to both "untreated" and "treated but uncontrolled" high BP. METHODS:We analyzed baseline data from 19,114 individuals aged ≥65 years enrolled from Australia and United States (US) in the ASPirin in Reducing Events in the Elderly study. Hypertension was defined as an average systolic/diastolic BP ≥140/90 mm Hg and/or the use of any BP lowering medication. "Controlled hypertension" was defined if participants were receiving antihypertensive medication and BP <140 and 90 mm Hg. Descriptive analyses were used to summarize hypertension control rates; logistic regression was used to investigate relationships with treatment and BP control. RESULTS:Overall, 74% (14,213/19,114) of participants were hypertensive; and of these 29% (4,151/14,213) were untreated. Among those treated participants, 53% (5,330/10,062) had BP ≥140/90 mm Hg. Participants who were untreated were more likely to be men, have higher educational status, and be in good physical health, and less likely to have significant comorbidities. The factors related to "treated but uncontrolled" BP included older age, male, Black race (vs. White), using antihypertensive monotherapy (vs. multiple) and residing in Australia (vs. US). CONCLUSIONS:High levels of "untreated" and "treated but uncontrolled" BP occur in healthy elderly people without CVD, suggesting there are opportunities for better BP control in the primary prevention of CVD in this population.

摘要

背景: 尽管有现成的治疗方法,但随着人口老龄化,血压 (BP) 的控制仍然不理想。此外,对老年人高血压管理的认识还存在差距。我们探讨了无明显心血管疾病 (CVD) 的老年高血压参与者的降压治疗和控制,并确定了与 “未治疗” 和 “治疗但未控制” 高 BP 相关的因素。 方法: 我们分析了来自澳大利亚和美国 (US) 的 19,114 名年龄 ≥ 65 岁的个体在阿司匹林减少老年事件研究中的基线数据。高血压定义为平均收缩压/舒张压 ≥ 140/90 mmhg 和/或使用任何降压药物。如果参与者接受抗高血压药物治疗且血压 <140 和 90毫米汞柱,则定义为 “控制高血压”。采用描述性分析总结高血压控制率; 采用 logistic 回归调查与治疗和血压控制的关系。 结果: 总的来说,74% (14,213/19,114) 的参与者是高血压; 而这 29% (4,151/14,213) 是未经治疗的。在那些接受治疗的参与者中,53% (5,330/10,062) 的 BP ≥ 140/90mm Hg。未经治疗的参与者更可能是男性,教育状况较高,身体健康,不太可能有明显的合并症。与 “治疗但未控制” BP 相关的因素包括年龄较大、男性、黑人种族 (vs.白色),使用抗高血压单药治疗 (vs.多个) 和居住在澳大利亚 (vs. US)。 结论: 高水平的 “未经治疗” 和 “治疗但不受控制” BP 发生在没有 CVD 的健康老年人中,提示在该人群 CVD 的一级预防中有更好的 BP 控制的机会。 临床试验注册: NCT01038583.

METHODS:BACKGROUND:Hypertensive disorders of pregnancy (HDP) increase cardiovascular disease (CVD) risk. Pregnancy morbidities, including preeclampsia, and CVD are common in systemic lupus erythematosus (SLE). Possible connections are important to explore. In a population-based cohort, we investigated whether HDP is associated with a higher risk of cardiovascular outcomes separately in SLE and non-SLE to examine the role of SLE. METHODS:We identified first singleton births in the Medical Birth Register (1987-2012) among mothers with SLE and a large general population comparison group. Discharge diagnoses for HDP, cardiovascular outcomes, and hypertension in the Patient Register were identified using ICD codes. We estimated adjusted hazard ratios and 95% confidence intervals (HR, 95% CI) of the association between HDP and outcomes, in separate models in women with and without SLE. We then evaluated additive and multiplicative effect modification using relative excess risk due to interaction and Cox models jointly accounting for SLE and HDP, respectively. Mediation analysis estimated the proportion of the association between SLE and outcome explained by HDP. RESULTS:HDP were more common in SLE pregnancies (20% vs 7%). In SLE, HDP were associated with a two-fold higher rate of cardiovascular outcomes and three-fold higher rate of incident hypertension. HDP mediated 20% of the latter association. In women without SLE, HDP was associated with higher hypertension incidence later in life. CONCLUSION:In women with and without SLE, HDP were associated with a three-fold higher rate of hypertension. In SLE, women with HDP developed cardiovascular outcomes twice as often as women without HDP.

METHODS:BACKGROUND:'Neuronal precursor cell expressed developmentally down-regulated 4-like' (NEDD4L) is considered a candidate gene for hypertension-both functionally and genetically-through the regulation of the ubiquitination of the epithelial sodium channel (ENaC). This study explores the relationship between genetic variation in NEDD4L and hypertension with chronic kidney disease (CKD) in the southeastern Han Chinese population. METHODS:We recruited 623 CKD patients and measured ambulatory blood pressure monitoring (ABPM), and the rs4149601 and rs2288774 polymorphisms in NEDD4L were genotyped using qPCR. RESULTS:For rs4149601, significant differences in genotype frequencies in an additive model (GG vs GA vs AA) were observed between normotensive patients and hypertensive patients when hypertension was classified into ambulatory hypertension, clinical hypertension and ambulatory systolic hypertension (P = 0.038, 0.005 and 0.006, respectively). In a recessive model (GG+GA vs AA), the frequency of the AA genotype of rs4149601 in the hypertension groups were all higher than that in the normotensive groups. The genotype distribution of rs2288774 did not differ significantly between the normotensive and hypertensive patients. In both the full cohort and the propensity score matching (PSM) cohort, the AA genotype of rs4149601 (compared to the GG+GA genotype group) was independently correlated with ambulatory hypertension, clinical hypertension and ambulatory systolic hypertension by multivariate logistic regression analysis. CONCLUSIONS:The present study indicates that the AA genotype of rs4149601 associates with hypertension in CKD. Consequently, the rs4149601 A allele might be a risk factor for hypertension with CKD.

METHODS:BACKGROUND:The burden of hypertension in many low-and middle-income countries is alarming and requires effective evidence-based preventative strategies that is carefully appraised and accepted by key stakeholders to ensure successful implementation and sustainability. We assessed nurses' perceptions of a recently completed Task Shifting Strategy for Hypertension control (TASSH) trial in Ghana, and facilitators and challenges to TASSH implementation. METHODS:Focus group sessions and in-depth interviews were conducted with 27 community health nurses from participating health centers and district hospitals involved in the TASSH trial implemented in the Ashanti Region, Ghana, West Africa from 2012 to 2017. TASSH evaluated the comparative effectiveness of the WHO-PEN program versus provision of health insurance for blood pressure reduction in hypertensive adults. Qualitative data were analyzed using open and axial coding techniques with emerging themes mapped onto the Consolidated Framework for Implementation Research (CFIR). RESULTS:Three themes emerged following deductive analysis using CFIR, including: (1) Patient health goal setting- relative priority and positive feedback from nurses, which motivated patients to make healthy behavior changes as a result of their health being a priority; (2) Leadership engagement (i.e., medical directors) which influenced the extent to which nurses were able to successfully implement TASSH in their various facilities, with most directors being very supportive; and (3) Availability of resources making it possible to implement the TASSH protocol, with limited space and personnel time to carry out TASSH duties, limited blood pressure (BP) monitoring equipment, and transportation, listed as barriers to effective implementation. CONCLUSION:Assessing stakeholders' perception of the TASSH implementation process guided by CFIR is crucial as it provides a platform for the nurses to thoroughly evaluate the task shifting program, while considering the local context in which the program is implemented. The feedback from the nurses informed barriers and facilitators to implementation of TASSH within the current healthcare system, and suggested system level changes needed prior to scale-up of TASSH to other regions in Ghana with potential for long-term sustainment of the task shifting intervention.
