Abstract
Hypertension is the leading risk factor for death and disability-adjusted life-years lost globally. Despite this tremendous impact on health, blood pressure measurement and treatment are relatively new to medical practice, with widespread measurement beginning just over 100 years ago. How, in such a short time, did blood pressure become such an integral measurement in medical practice that it is now considered one of the vital signs? Key revelations through Stephen Hales and his horse experiment, Riva-Rocci's modern blood pressure cuff, Korotkoff sounds, and President Roosevelt's death set the stage for discovery. Landmark trials such as the VA Cooperative studies of the 1960s through the recent Systolic Blood Pressure Intervention Trial and Prevention with Mediterranean Diet trials provide the foundation for modern clinical practice. An understanding of the history of hypertension can directly affect current clinical practice and offers unique insights into how the medical community has approached the management of one of the deadliest medical conditions in history.

[PMID: 30274771 DOI: 10.1016/j.arteri.2018.07.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Revised: 07/07/2018] [Accepted: 07/18/2018] [Indexed: 12/22/2022]
Abstract
High blood pressure in individuals with type2 diabetes mellitus increases the risk of cardiovascular events. The international management guidelines recommend starting pharmacological treatment with blood pressure values >140/90mmHg. However, there is no optimal cut-off point from which cardiovascular events can be reduced without causing adverse events. A blood pressure range of >130/80 to <140/90mmHg seems to be adequate. These values can be achieved through non-pharmacological (diet, exercise) and pharmacological interventions (using drugs that have been shown to reduce cardiovascular events). The choice of one or several drugs must be individualised, according to factors including, ethnicity, age, and associated comorbidities, among others.

Abstract
High blood pressure in patients with diabetes mellitus results in a significant increase in the risk of cardiovascular events and mortality. The current evidence regarding the impact of intervention on blood pressure levels (in accordance with a specific threshold) is not particularly robust. Blood pressure control is more difficult to achieve in patients with diabetes than in non-diabetic patients, and requires using combination therapy in most patients. Different management guidelines recommend initiating pharmacological therapy with values >140/90 mm/Hg; however, an optimal cut point for this population has not been established. Based on the available evidence, it appears that blood pressure targets will probably have to be lower than <140/90mmHg, and that values approaching 130/80mmHg should be recommended. Initial treatment of hypertension in diabetes should include drug classes demonstrated to reduce cardiovascular events; i.e., angiotensin converting-enzyme inhibitors, angiotensin receptor blockers, diuretics, or dihydropyridine calcium channel blockers. The start of therapy must be individualized in accordance with the patient's baseline characteristics, and factors such as associated comorbidities, race, and age, inter alia.

Diastolic Blood Pressure is a Risk Factor for Peri-procedural Stroke Following Carotid Endarterectomy in Asymptomatic Patients. Eur J Vasc Endovasc Surg 2017; 53:626-631.

Abstract
Objective/Background Carotid endarterectomy (CEA) prevents future stroke, but this benefit depends on detection and control of high peri-operative risk factors. In symptomatic patients, diastolic hypertension has been causally related to procedural stroke following CEA. The aim was to identify risk factors causing peri-procedural stroke in asymptomatic patients and to relate these to timing of surgery and mechanism of stroke. Methods In the first Asymptomatic Carotid Surgery Trial (ACST-1), 3,120 patients with severe asymptomatic carotid stenosis were randomly assigned to CEA plus medical therapy or to medical therapy alone. In 1,425 patients having their allocated surgery, baseline patient characteristics were analysed to identify factors associated with peri-procedural (< 30 days) stroke or death. Multivariate analysis was performed on risk factors with a p value < .3 from univariate analysis. Event timing and mechanism of stroke were analysed using chi-square tests. Results A total of 36 strokes (27 ischaemic, four haemorrhagic, five unknown type) and six other deaths occurred during the peri-procedural period, resulting in a stroke/death rate of 2.9% (42/1,425). Diastolic blood pressure at randomisation was the only significant risk factor in univariate analysis (odds ratio [OR] 1.34 per 10 mmHg, 95% confidence interval [CI] 1.04–1.72; p = .02) and this remained so in multivariate analysis when corrected for sex, age, lipid lowering therapy, and prior infarcts or symptoms (OR 1.34, 95% CI 1.05–1.72; p = .02). In patients with diastolic hypertension (> 90 mmHg) most strokes occurred during the procedure (67% vs. 20%; p = .02). Conclusion In ACST-1, diastolic blood pressure was the only independent risk factor associated with peri-procedural stroke or death. While the underlying mechanisms of the association between lower diastolic blood pressure and peri-procedural risk remain unclear, good pre-operative control of blood pressure may improve procedural outcome of carotid surgery in asymptomatic patients.

Abstract
The natriuretic peptide (NP) system is an important endocrine, autocrine and paracrine system, consisting of a family of peptides which provide cardiac, renal and vascular effects that, through their beneficial physiological actions, play a key role in maintaining overall cardiovascular health. Traditionally, the pathophysiological origins of cardio-renal disease have been viewed as the domain of the renin-angiotensin-aldosterone system (RAAS) and the sympathetic nervous system (SNS), with inappropriate activation of both systems leading to deleterious changes in cardio-renal function and structure. Therapies designed to suppress the RAAS and the SNS have been routinely employed to address the consequences of cardio-renal disease. However, it is now becoming increasingly apparent that enhancing the beneficial physiological effects of the NP system may represent an attractive alternative therapeutic approach to counter the pathophysiological effects of disease. In particular, innovative therapeutic strategies aimed at enhancing the physiological benefits afforded by NPs while simultaneously suppressing the RAAS are generating increasing interest as potential treatment options for the management of cardio-renal disease.

Abstract
Treatment of hypertension in the elderly is expected to become more complex in the coming decades. Based on the current landscape of clinical trials, guideline recommendations remain inconclusive. The present review discusses the latest evidence derived from studies available in 2013 and investigates optimal blood pressure (BP) and preferred treatment substances. Three common archetypes are discussed that hamper the treatment of hypertension in the very elderly. In addition, this paper presents the current recommendations of the NICE 2011, JNC7 2013-update, ESH/ESC 2013, CHEP 2013, JNC8 and ASH/ISH guidelines for elderly patients. Advantages of the six main substance classes, namely diuretics, beta-blockers (BBs), calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), and direct renin inhibitors (DRIs) are discussed. Medical and economic implications of drug administration in the very elderly are presented. Avoidance of treatment-related adverse effects has become increasingly relevant. Current substance classes are equally effective, with similar effects on cardiovascular outcomes. Selection of substances should therefore also be based on collateral advantages of drugs that extend beyond BP reduction. The combination of ACEIs and diuretics appears to be favorable in managing systolic/diastolic hypertension. Diuretics are a preferred and cheap combination drug, and the combination with CCBs is recommended for patients with isolated systolic hypertension. ACEIs and CCBs are favorable for patients with dementia, while CCBs and ARBs imply substantial cost savings due to high adherence.

Abstract
BACKGROUND BP control is suboptimal Worldwide. Little is known about attitudes of health professionals toward their BP status. AIM To estimate awareness, attitudes, and distribution of blood pressure among health professionals. STUDY DESIGN Prospective cross-sectional survey. METHODS Study was conducted among health professionals in two tertiary hospitals in Riyadh, KSA during December 2010. Socio-demographics, risk factors for high BP, awareness, and adherence to treatment were recorded. RESULTS Six hundred and seventy-two subjects, 66.6% females, mean age 36.2 + 13.9 years. Prevalence of Hypertension (HTN) was 28%. 114 (60.6%) patients had self reported HTN in HTN group while 74 (11%) of total study population, were not aware that they have HTN which was detected on screening. Stress and lack of formal exercise were prevalent risk factors for HTN, present in 44.1% and 36.1%, of patients, respectively, while obesity was present in 19.4%. Many participants were not aware of recently recommended target value of blood pressure. 22.3% patients were irregular for their follow-up. 12.2% patients were not adherent to the treatment. Isolated systolic hypertension was more common in men. A point of serious concern was that relatively young health professionals, who were not known to be hypertensive did not monitor their BP, found to have HTN. CONCLUSION Suboptimal awareness and lack of adherence to the treatment for BP among health professionals is of serious concern, for increased chances of cardiovascular events. Physical exercise, correction of obesity and compliance with treatment may reduce the risk of HTN-related adverse outcome in this special subset of the population.

Abstract
In the era of aggressive control of cardiovascular risk factors such as hypertension, the mantra of "lower is better" has taken a strong foothold. Although there is clear epidemiologic evidence that lower blood pressure improves specific organ-related outcomes, this rule does not apply to all patients and definitely not all target organs. The concept of J-curve or adverse outcomes at lower blood pressure has been proposed for more than three decades but has recently come under increasing scrutiny. Specifically, a relationship between adverse cardiovascular outcomes and low diastolic blood pressure has been observed in multiple clinical trials. In this article we review the advances in understanding of the J-curve phenomenon and include a discussion on specific populations that might be at higher risk due to the J-curve relationship.

Abstract
AIMS To evaluate the association of low-density lipoprotein, high-density lipoprotein and non-high-density lipoprotein cholesterol with the risk of stroke, diabetes-related vascular events and mortality in elderly diabetes patients. METHODS This study was carried out as a post-hoc landmark analysis of a randomized, controlled, multicenter, prospective intervention trial. We included 1173 elderly type 2 diabetes patients (aged ≥ 65 years) from 39 Japanese institutions who were enrolled in the Japanese elderly diabetes intervention trial study and who could be followed up for 1 year. A landmark survival analysis was carried out in which follow up was set to start 1 year after the initial time of entry. RESULTS During 6 years of follow up, there were 38 cardiovascular events, 50 strokes, 21 diabetes-related deaths and 113 diabetes-related events. High low-density lipoprotein cholesterol was associated with incident cardiovascular events, and high glycated hemoglobin was associated with strokes. After adjustment for possible covariables, non-high-density lipoprotein cholesterol showed a significant association with increased risk of stroke, diabetes-related mortality and total events. The adjusted hazard ratios (95% confidence intervals) of non-high-density lipoprotein cholesterol were 1.010 (1.001-1.018, P = 0.029) for stroke, 1.019 (1.007-1.031, P < 0.001) for diabetes-related death and 1.008 (1.002-1.014; P < 0.001) for total diabetes-related events. CONCLUSIONS Higher non-high-density lipoprotein cholesterol was associated with an increased risk of stroke, diabetes-related mortality and total events in elderly diabetes patients.

Abstract
Hypertension (HT) is considered the main classic vascular risk factor for stroke and the importance of lowering blood pressure (BP) is well established. However, not all the benefit of antihypertensive treatment is due to BP reduction per se, as the effect of reducing the risk of stroke differs among classes of antihypertensive agents. Extensive evidences support that angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB), dihydropyridine calcium channel blockers (CCB) and thiazide diuretics each reduced risk of stroke compared with placebo or no treatment. Therefore, when combination therapy is required, a combination of these antihypertensive classes represents a logical approach. Despite the efficacy of antihypertensive therapy a large proportion of the population, still has undiagnosed or inadequately treated HT, and remain at high risk of stroke. In primary stroke prevention current guidelines recommend a systolic/diastolic BP goal of <140/<90 mmHg in the general population and <130/80 mmHg in diabetics and in subjects with high cardiovascular risk and renal disease. The recent release in the market of the fixed-dose combination (FDC) of ACEI or ARB and CCB should provide a better control of BP. However to confirm the efficacy of the FDC in primary stroke prevention, clinical intervention trials are needed.
