Abstract
Hypertension impacts most older adults as one of many multiple chronic conditions. A thorough evaluation is required to assess overall health, cardiovascular status, and comorbid conditions that impact treatment targets. In the absence of severe frailty or dementia, intensive treatment prevents more cardiovascular events than standard treatment and may slow cognitive decline. "Start low and go slow" is not the best strategy for many older adults as fewer cardiovascular events occur when hypertension is controlled within the first 3 to 6 months of treatment.

Abstract
The past two to three decades have seen a steady increase in the prevalence of hypertension in China, largely owing to increased life expectancy and lifestyle changes (particularly among individuals aged 35-44 years). Data from the China hypertension survey conducted in 2012-2015 revealed a high prevalence of grade 3 hypertension (systolic blood pressure ≥180 mmHg and diastolic blood pressure ≥110 mmHg) in the general population, which increased with age to up to 5% among individuals aged ≥65 years. The risk profile of patients with hypertension in China has also been a subject of intense study in the past 30 years. Dietary sodium and potassium intake have remained largely the same in China in the past three decades, and salt substitution strategies seem to be effective in reducing blood pressure levels and the risk of cardiovascular events and death. However, the number of individuals with risk factors for hypertension and cardiovascular disease in general, such as physical inactivity and obesity, has increased dramatically in the same period. Moreover, even in patients diagnosed with hypertension, their disease is often poorly managed owing to a lack of patient education and poor treatment compliance. In this Review, we summarize the latest epidemiological data on hypertension in China, discuss the risk factors for hypertension that are specific to this population, and describe several ongoing nationwide hypertension control initiatives that target these risk factors, especially in the low-resource rural setting.

Front Cardiovasc Med 2022; 9:986502. [PMID: 36337902 PMCID: PMC9626501 DOI: 10.3389/fcvm.2022.986502] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 10/03/2022] [Indexed: 12/03/2022] Open
Abstract
Background The blood pressure (BP) threshold for initial pharmacological treatment remains controversial. The number needed to treat (NNT) is a significant indicator. This study aimed to explore the benefits and risks of antihypertensive medications in participants with different systolic BPs (SBPs), and cardiovascular disease status from the perspective of the NNT. Methods We conducted a meta-analysis of 52 randomized placebo-controlled trials. The data were extracted from published articles and pooled to calculate NNTs. The participants were divided into five groups, based on the mean SBP at entry (120–129.9, 130–139.9, 140–159.9, 160–179.9, and ≥180 mmHg). Furthermore, we stratified patients into those with and without cardiovascular disease. The primary outcomes were the major adverse cardiovascular events (MACEs), and adverse events (AEs) leading to discontinuation. Results Antihypertensive medications were not associated with MACEs, however, it increased AEs, when the SBP was <140 mmHg. For participants with cardiovascular disease or at a high risk of heart failure and stroke, antihypertensive treatment reduced MACEs when SBP was ≥130 mmHg. Despite this, only 2–4 subjects had reduced MACEs per 100 patients receiving antihypertensive medications for 3.50 years. The number of individuals who needed to treat to avoid MACEs declined with an increased cardiovascular risk. Conclusion Pharmacological treatment could be activated when SBP reaches 140 mmHg. For people with cardiovascular disease or at a higher risk of stroke and heart failure, 130 mmHg may be a better therapeutic threshold. It could be more cost-effective to prioritize antihypertensive medications for people with a high risk of developing cardiovascular disease.

Abstract
BACKGROUND The prevalence of uncontrolled hypertension is high and increasing in low-income and middle-income countries. We tested the effectiveness of a multifaceted intervention for blood pressure control in rural China led by village doctors (community health workers on the front line of primary health care). METHODS In this open, cluster randomised trial (China Rural Hypertension Control Project), 326 villages that had a regular village doctor and participated in the China New Rural Cooperative Medical Scheme were randomly assigned (1:1) to either village doctor-led multifaceted intervention or enhanced usual care (control), with stratification by provinces, counties, and townships. We recruited individuals aged 40 years or older with an untreated blood pressure of 140/90 mm Hg or higher (≥130/80 mm Hg among those with a history of cardiovascular disease, diabetes, or chronic kidney disease) or a treated blood pressure of 130/80 mm Hg or higher. In the intervention group, trained village doctors initiated and titrated antihypertensive medications according to a standard protocol with supervision from primary care physicians. Village doctors also conducted health coaching on home blood pressure monitoring, lifestyle changes, and medication adherence. The primary outcome (reported here) was the proportion of patients with a blood pressure of less than 130/80 mm Hg at 18 months. The analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT03527719, and is ongoing. FINDINGS Between May 8 and November 28, 2018, we enrolled 33 995 individuals from 163 intervention and 163 control villages. At 18 months, 8865 (57·0%) of 15 414 patients in the intervention group and 2895 (19·9%) of 14 500 patients in the control group had a blood pressure of less than 130/80 mm Hg, with a group difference of 37·0% (95% CI 34·9 to 39·1%; p<0·0001). Mean systolic blood pressure decreased by -26·3 mm Hg (95% CI -27·1 to -25·4) from baseline to 18 months in the intervention group and by -11·8 mm Hg (-12·6 to -11·0) in the control group, with a group difference of -14·5 mm Hg (95% CI -15·7 to -13·3 mm Hg; p<0·0001). Mean diastolic blood pressure decreased by -14·6 mm Hg (-15·1 to -14·2) from baseline to 18 months in the intervention group and by -7·5 mm Hg (-7·9 to -7·2) in the control group, with a group difference of -7·1 mm Hg (-7·7 to -6·5 mm Hg; p<0·0001). No treatment-related serious adverse events were reported in either group. INTERPRETATION Compared with enhanced usual care, village doctor-led intervention resulted in statistically significant improvements in blood pressure control among rural residents in China. This feasible, effective, and sustainable implementation strategy could be scaled up in rural China and other low-income and middle-income countries for hypertension control.

Abstract
Raised blood pressure (BP) is the leading cause of death and disability worldwide, and its particular strong association with stroke is well established. Although systolic BP increases with age in both sexes, raised BP is more prevalent in males in early adulthood, overtaken by females at middle age, consistently across all ethnicities/races. However, there are clear regional differences on when females overtake males. Higher BP among males is observed until the seventh decade of life in high-income countries, compared with almost 3 decades earlier in low- and middle-income countries. Females and males tend to have different cardiovascular disease risk profiles, and many lifestyles also influence BP and cardiovascular disease in a sex-specific manner. Although no hypertension guidelines distinguish between sexes in BP thresholds to define or treat hypertension, observational evidence suggests that in terms of stroke risk, females would benefit from lower BP thresholds to the magnitude of 10 to 20 mm Hg. More randomized evidence is needed to determine if females have greater cardiovascular benefits from lowering BP and whether optimal BP is lower in females. Since 1990, the number of people with hypertension worldwide has doubled, with most of the increase occurring in low- and-middle-income countries where the greatest population growth was also seen. Sub-Saharan Africa, Oceania, and South Asia have the lowest detection, treatment, and control rates. High BP has a more significant effect on the burden of stroke among Black and Asian individuals than Whites, possibly attributable to differences in lifestyle, socioeconomic status, and health system resources. Although pharmacological therapy is recommended differently in local guidelines, recommendations on lifestyle modification are often very similar (salt restriction, increased potassium intake, reducing weight and alcohol, smoking cessation). This overall enhanced understanding of the sex- and ethnic/racial-specific attributes to BP motivates further scientific discovery to develop more effective prevention and treatment strategies to prevent stroke in high-risk populations.

Abstract
BACKGROUND This is the first update of a review published in 2010. While calcium channel blockers (CCBs) are often recommended as a first-line drug to treat hypertension, the effect of CCBs on the prevention of cardiovascular events, as compared with other antihypertensive drug classes, is still debated. OBJECTIVES To determine whether CCBs used as first-line therapy for hypertension are different from other classes of antihypertensive drugs in reducing the incidence of major adverse cardiovascular events. SEARCH METHODS For this updated review, the Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials (RCTs) up to 1 September 2020: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2020, Issue 1), Ovid MEDLINE, Ovid Embase, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also contacted the authors of relevant papers regarding further published and unpublished work and checked the references of published studies to identify additional trials. The searches had no language restrictions. SELECTION CRITERIA Randomised controlled trials comparing first-line CCBs with other antihypertensive classes, with at least 100 randomised hypertensive participants and a follow-up of at least two years. DATA COLLECTION AND ANALYSIS Three review authors independently selected the included trials, evaluated the risk of bias, and entered the data for analysis. Any disagreements were resolved through discussion. We contacted study authors for additional information. MAIN RESULTS This update contains five new trials. We included a total of 23 RCTs (18 dihydropyridines, 4 non-dihydropyridines, 1 not specified) with 153,849 participants with hypertension. All-cause mortality was not different between first-line CCBs and any other antihypertensive classes. As compared to diuretics, CCBs probably increased major cardiovascular events (risk ratio (RR) 1.05, 95% confidence interval (CI) 1.00 to 1.09, P = 0.03) and increased congestive heart failure events (RR 1.37, 95% CI 1.25 to 1.51, moderate-certainty evidence). As compared to beta-blockers, CCBs reduced the following outcomes: major cardiovascular events (RR 0.84, 95% CI 0.77 to 0.92), stroke (RR 0.77, 95% CI 0.67 to 0.88, moderate-certainty evidence), and cardiovascular mortality (RR 0.90, 95% CI 0.81 to 0.99, low-certainty evidence). As compared to angiotensin-converting enzyme (ACE) inhibitors, CCBs reduced stroke (RR 0.90, 95% CI 0.81 to 0.99, low-certainty evidence) and increased congestive heart failure (RR 1.16, 95% CI 1.06 to 1.28, low-certainty evidence). As compared to angiotensin receptor blockers (ARBs), CCBs reduced myocardial infarction (RR 0.82, 95% CI 0.72 to 0.94, moderate-certainty evidence) and increased congestive heart failure (RR 1.20, 95% CI 1.06 to 1.36, low-certainty evidence). AUTHORS' CONCLUSIONS For the treatment of hypertension, there is moderate certainty evidence that diuretics reduce major cardiovascular events and congestive heart failure more than CCBs. There is low to moderate certainty evidence that CCBs probably reduce major cardiovascular events more than beta-blockers. There is low to moderate certainty evidence that CCBs reduced stroke when compared to angiotensin-converting enzyme (ACE) inhibitors and reduced myocardial infarction when compared to angiotensin receptor blockers (ARBs), but increased congestive heart failure when compared to ACE inhibitors and ARBs. Many of the differences found in the current review are not robust, and further trials might change the conclusions. More well-designed RCTs studying the mortality and morbidity of individuals taking CCBs as compared with other antihypertensive drug classes are needed for patients with different stages of hypertension, different ages, and with different comorbidities such as diabetes.

Abstract
INTRODUCTION Hypertension is a major and modifiable risk factor for cardiovascular disease. Its prevalence is rising as the result of population aging. Isolated systolic hypertension mostly occurs in older patients accounting for up to 80% of cases. AREAS COVERED The authors systematically review published studies to appraise the scientific and clinical evidence supporting the role of blood pressure control in elderly patients with isolated systolic hypertension, and to assess the influence of different drug treatment regimens on outcomes. EXPERT OPINION Antihypertensive treatment of isolated systolic hypertension significantly reduces the risk of morbidity and mortality in elderly patients. Thiazide diuretics and dihydropyridine calcium-channel blockers are the primary compounds used in randomized clinical trials. These drugs can be considered as first-line agents for the management of isolated systolic hypertension. Free or fixed combination therapy with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and calcium-channel blockers or thiazide-like diuretics should also be considered, particularly when compelling indications such as coronary artery disease, chronic kidney disease, diabetes, and congestive heart failure coexist. There is also hot scientific debate on the optimal blood pressure target to be achieved in elderly patients with isolated systolic hypertension, but current recommendations are scarcely supported by evidence.

Management of hypertension in the very old: an intensive reduction of blood pressure should be achieved in most patients. J Hum Hypertens 2020; 34:551-556. [PMID: 32398768 DOI: 10.1038/s41371-020-0345-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 03/23/2020] [Accepted: 04/24/2020] [Indexed: 01/03/2023]
Abstract
There is large evidence that treatment of hypertension significantly reduces the risk of morbidity and mortality in the elderly. Although it is generally accepted that the benefit of antihypertensive treatment is largely explained by the reduction in systolic blood pressure, the optimal blood pressure target in elderly patients is still a topic of debate. Unfortunately, the clinical trials which demonstrated the benefit of antihypertensive treatment in old and very old patients with hypertension included relatively fit patients since frail patients were generally excluded. Available data suggest that when treating older adults, and especially frail older hypertensive adults, extra caution is appropriate in the setting of significant adverse events. Nonetheless, recent observations demonstrated a similar benefit from a more intensive compared with a less intensive blood pressure lowering in both fit and frail older adults. Of note, the rate of serious adverse events appears not dissimilar in the two treatment strategies, and not associated to frailty. Taken together, these findings support the concept that an intensive therapeutic strategy appears reasonable even in elderly hypertensive patients, particularly when the treatment is well tolerated.

Abstract
BACKGROUND This is the second substantive update of this review. It was originally published in 1998 and was previously updated in 2009. Elevated blood pressure (known as 'hypertension') increases with age - most rapidly over age 60. Systolic hypertension is more strongly associated with cardiovascular disease than is diastolic hypertension, and it occurs more commonly in older people. It is important to know the benefits and harms of antihypertensive treatment for hypertension in this age group, as well as separately for people 60 to 79 years old and people 80 years or older. OBJECTIVES Primary objective• To quantify the effects of antihypertensive drug treatment as compared with placebo or no treatment on all-cause mortality in people 60 years and older with mild to moderate systolic or diastolic hypertensionSecondary objectives• To quantify the effects of antihypertensive drug treatment as compared with placebo or no treatment on cardiovascular-specific morbidity and mortality in people 60 years and older with mild to moderate systolic or diastolic hypertension• To quantify the rate of withdrawal due to adverse effects of antihypertensive drug treatment as compared with placebo or no treatment in people 60 years and older with mild to moderate systolic or diastolic hypertension SEARCH METHODS: The Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials up to 24 November 2017: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE Ovid (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We contacted authors of relevant papers regarding further published and unpublished work. SELECTION CRITERIA Randomised controlled trials of at least one year's duration comparing antihypertensive drug therapy versus placebo or no treatment and providing morbidity and mortality data for adult patients (≥ 60 years old) with hypertension defined as blood pressure greater than 140/90 mmHg. DATA COLLECTION AND ANALYSIS Outcomes assessed were all-cause mortality; cardiovascular morbidity and mortality; cerebrovascular morbidity and mortality; coronary heart disease morbidity and mortality; and withdrawal due to adverse effects. We modified the definition of cardiovascular mortality and morbidity to exclude transient ischaemic attacks when possible. MAIN RESULTS This update includes one additional trial (MRC-TMH 1985). Sixteen trials (N = 26,795) in healthy ambulatory adults 60 years or older (mean age 73.4 years) from western industrialised countries with moderate to severe systolic and/or diastolic hypertension (average 182/95 mmHg) met the inclusion criteria. Most of these trials evaluated first-line thiazide diuretic therapy for a mean treatment duration of 3.8 years.Antihypertensive drug treatment reduced all-cause mortality (high-certainty evidence; 11% with control vs 10.0% with treatment; risk ratio (RR) 0.91, 95% confidence interval (CI) 0.85 to 0.97; cardiovascular morbidity and mortality (moderate-certainty evidence; 13.6% with control vs 9.8% with treatment; RR 0.72, 95% CI 0.68 to 0.77; cerebrovascular mortality and morbidity (moderate-certainty evidence; 5.2% with control vs 3.4% with treatment; RR 0.66, 95% CI 0.59 to 0.74; and coronary heart disease mortality and morbidity (moderate-certainty evidence; 4.8% with control vs 3.7% with treatment; RR 0.78, 95% CI 0.69 to 0.88. Withdrawals due to adverse effects were increased with treatment (low-certainty evidence; 5.4% with control vs 15.7% with treatment; RR 2.91, 95% CI 2.56 to 3.30. In the three trials restricted to persons with isolated systolic hypertension, reported benefits were similar.This comprehensive systematic review provides additional evidence that the reduction in mortality observed was due mostly to reduction in the 60- to 79-year-old patient subgroup (high-certainty evidence; RR 0.86, 95% CI 0.79 to 0.95). Although cardiovascular mortality and morbidity was significantly reduced in both subgroups 60 to 79 years old (moderate-certainty evidence; RR 0.71, 95% CI 0.65 to 0.77) and 80 years or older (moderate-certainty evidence; RR 0.75, 95% CI 0.65 to 0.87), the magnitude of absolute risk reduction was probably higher among 60- to 79-year-old patients (3.8% vs 2.9%). The reduction in cardiovascular mortality and morbidity was primarily due to a reduction in cerebrovascular mortality and morbidity. AUTHORS' CONCLUSIONS Treating healthy adults 60 years or older with moderate to severe systolic and/or diastolic hypertension with antihypertensive drug therapy reduced all-cause mortality, cardiovascular mortality and morbidity, cerebrovascular mortality and morbidity, and coronary heart disease mortality and morbidity. Most evidence of benefit pertains to a primary prevention population using a thiazide as first-line treatment.

Abstract
BACKGROUND The influence of age on balance of benefit vs. potential harm of blood pressure (BP)-lowering therapy for elderly hypertensives is unclear. We evaluated the modifying effects of age on BP lowering for various adverse outcomes in hypertensive patients older than 60 years without specified comorbidities. METHODS All relevant randomized controlled trials (RCTs) were systematically identified. Coronary heart disease, stroke, heart failure (HF), cardiovascular death, major adverse cardiovascular events (MACE), renal failure (RF), and all-cause death were assessed. Meta-regression analysis was used to explore the relationship between achieved systolic BP (SBP) and the risk of adverse events. Random-effects meta-analysis was used to pool the estimates. RESULTS Our study included 18 RCTs (n = 53,993). Meta-regression analysis showed a lower achieved SBP related with a lower risk of stroke and cardiovascular death, but an increased risk of RF. The regression slopes were comparable between populations stratifying by age 75 years. In subgroup analysis, the relative risks of a more aggressive BP lowering strategy were similar between patients aged older or less than 75 years for all outcomes except for RF (P for interaction = 0.02). Compared to treatment with final achieved SBP 140-150 mm Hg, a lower achieved SBP (<140 mm Hg) was significantly associated with decreased risk of stroke (relative risk = 0.68; 95% confidence interval = 0.55-0.85), HF (0.77; 0.60-0.99), cardiovascular death (0.68; 0.52-0.89), and MACE (0.83; 0.69-0.99). CONCLUSIONS To treat hypertension in the elderly, age had trivial effect modification on most outcomes, except for renal failure. Close monitoring of renal function may be warranted in the management of elderly hypertension.

Abstract
INTRODUCTION Cardiovascular disease is a leading cause of mortality in the elderly. Hypertension is an important modifiable risk factor that contributes to cardiovascular morbidity and mortality. The prevalence of hypertension is known to increase with age, and hypertension has been associated with an increase in risk for cardiovascular disease in the elderly. There is a wealth of evidence that supports aggressive control of blood pressure to lower cardiovascular risk in the general population. However, there are limited data to guide management of hypertension in the elderly and frail patient subgroups. These subgroups are inadequately treated due to lack of clarity regarding blood pressure thresholds, treatment targets, comorbidities, frailty, drug interactions from polypharmacy, and high cost of care. Areas covered: We review the current evidence behind the definition, goals, and treatments for hypertension in the elderly and frail and outline a strategy that can be used to guide antihypertensive pharmacotherapy in this population. Expert commentary: Lower blood pressure to < 130/80 mm Hg in elderly patients if tolerated and promote use of combination therapy if the blood pressure is > 20/10 mm Hg over the goal blood pressure. Antihypertensive treatment regimens must be tailored to each individual based on their comorbidities, risk for adverse effects, and potential drug interactions ( Figure 1 ).

Abstract
BACKGROUND This is the first update of a review published in 2009. Sustained moderate to severe elevations in resting blood pressure leads to a critically important clinical question: What class of drug to use first-line? This review attempted to answer that question. OBJECTIVES To quantify the mortality and morbidity effects from different first-line antihypertensive drug classes: thiazides (low-dose and high-dose), beta-blockers, calcium channel blockers, ACE inhibitors, angiotensin II receptor blockers (ARB), and alpha-blockers, compared to placebo or no treatment.Secondary objectives: when different antihypertensive drug classes are used as the first-line drug, to quantify the blood pressure lowering effect and the rate of withdrawal due to adverse drug effects, compared to placebo or no treatment. SEARCH METHODS The Cochrane Hypertension Information Specialist searched the following databases for randomized controlled trials up to November 2017: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We contacted authors of relevant papers regarding further published and unpublished work. SELECTION CRITERIA Randomized trials (RCT) of at least one year duration, comparing one of six major drug classes with a placebo or no treatment, in adult patients with blood pressure over 140/90 mmHg at baseline. The majority (over 70%) of the patients in the treatment group were taking the drug class of interest after one year. We included trials with both hypertensive and normotensive patients in this review if the majority (over 70%) of patients had elevated blood pressure, or the trial separately reported outcome data on patients with elevated blood pressure. DATA COLLECTION AND ANALYSIS The outcomes assessed were mortality, stroke, coronary heart disease (CHD), total cardiovascular events (CVS), decrease in systolic and diastolic blood pressure, and withdrawals due to adverse drug effects. We used a fixed-effect model to to combine dichotomous outcomes across trials and calculate risk ratio (RR) with 95% confidence interval (CI). We presented blood pressure data as mean difference (MD) with 99% CI. MAIN RESULTS The 2017 updated search failed to identify any new trials. The original review identified 24 trials with 28 active treatment arms, including 58,040 patients. We found no RCTs for ARBs or alpha-blockers. These results are mostly applicable to adult patients with moderate to severe primary hypertension. The mean age of participants was 56 years, and mean duration of follow-up was three to five years.High-quality evidence showed that first-line low-dose thiazides reduced mortality (11.0% with control versus 9.8% with treatment; RR 0.89, 95% CI 0.82 to 0.97); total CVS (12.9% with control versus 9.0% with treatment; RR 0.70, 95% CI 0.64 to 0.76), stroke (6.2% with control versus 4.2% with treatment; RR 0.68, 95% CI 0.60 to 0.77), and coronary heart disease (3.9% with control versus 2.8% with treatment; RR 0.72, 95% CI 0.61 to 0.84).Low- to moderate-quality evidence showed that first-line high-dose thiazides reduced stroke (1.9% with control versus 0.9% with treatment; RR 0.47, 95% CI 0.37 to 0.61) and total CVS (5.1% with control versus 3.7% with treatment; RR 0.72, 95% CI 0.63 to 0.82), but did not reduce mortality (3.1% with control versus 2.8% with treatment; RR 0.90, 95% CI 0.76 to 1.05), or coronary heart disease (2.7% with control versus 2.7% with treatment; RR 1.01, 95% CI 0.85 to 1.20).Low- to moderate-quality evidence showed that first-line beta-blockers did not reduce mortality (6.2% with control versus 6.0% with treatment; RR 0.96, 95% CI 0.86 to 1.07) or coronary heart disease (4.4% with control versus 3.9% with treatment; RR 0.90, 95% CI 0.78 to 1.03), but reduced stroke (3.4% with control versus 2.8% with treatment; RR 0.83, 95% CI 0.72 to 0.97) and total CVS (7.6% with control versus 6.8% with treatment; RR 0.89, 95% CI 0.81 to 0.98).Low- to moderate-quality evidence showed that first-line ACE inhibitors reduced mortality (13.6% with control versus 11.3% with treatment; RR 0.83, 95% CI 0.72 to 0.95), stroke (6.0% with control versus 3.9% with treatment; RR 0.65, 95% CI 0.52 to 0.82), coronary heart disease (13.5% with control versus 11.0% with treatment; RR 0.81, 95% CI 0.70 to 0.94), and total CVS (20.1% with control versus 15.3% with treatment; RR 0.76, 95% CI 0.67 to 0.85).Low-quality evidence showed that first-line calcium channel blockers reduced stroke (3.4% with control versus 1.9% with treatment; RR 0.58, 95% CI 0.41 to 0.84) and total CVS (8.0% with control versus 5.7% with treatment; RR 0.71, 95% CI 0.57 to 0.87), but not coronary heart disease (3.1% with control versus 2.4% with treatment; RR 0.77, 95% CI 0.55 to 1.09), or mortality (6.0% with control versus 5.1% with treatment; RR 0.86, 95% CI 0.68 to 1.09).There was low-quality evidence that withdrawals due to adverse effects were increased with first-line low-dose thiazides (5.0% with control versus 11.3% with treatment; RR 2.38, 95% CI 2.06 to 2.75), high-dose thiazides (2.2% with control versus 9.8% with treatment; RR 4.48, 95% CI 3.83 to 5.24), and beta-blockers (3.1% with control versus 14.4% with treatment; RR 4.59, 95% CI 4.11 to 5.13). No data for these outcomes were available for first-line ACE inhibitors or calcium channel blockers. The blood pressure data were not used to assess the effect of the different classes of drugs as the data were heterogeneous, and the number of drugs used in the trials differed. AUTHORS' CONCLUSIONS First-line low-dose thiazides reduced all morbidity and mortality outcomes in adult patients with moderate to severe primary hypertension. First-line ACE inhibitors and calcium channel blockers may be similarly effective, but the evidence was of lower quality. First-line high-dose thiazides and first-line beta-blockers were inferior to first-line low-dose thiazides.

Abstract
INTRODUCTION Hypertension is more prevalent in the elderly (age>65 years) diabetic population than in the general population and shows an increasing prevalence with advancing age. Both diabetes mellitus (DM) and hypertension are independent risk factors for cardiovascular (CV) related morbidity and mortality. Optimal BP targets were not identified in elderly patients with DM and hypertension. AREAS COVERED In this review article, the authors briefly discuss the pathophysiology of hypertension in elderly diabetics, present evidence with various antihypertensive drug classes supporting the treatment of hypertension to reduce CV events in older diabetics, and then discuss the optimal target BP goals in these patients. EXPERT OPINION Clinicians should have a BP goal of less than 130/80 mm in all elderly patients with hypertension and DM, especially in those with high CV-risk. When medications are required for optimal BP control in addition to lifestyle measures, either thiazide diuretics, angiotensin-converting-enzyme inhibitors, angiotensin receptor blockers, or calcium channel blockers should be considered as initial therapy. Combinations of medications are usually required in these patients because BP control is more difficult to achieve in diabetics than those without DM.

Abstract
Previous studies have focused mostly on independent effects of the stroke risk factors, whereas little attention has been paid to interactions between individual factors which may be important for stroke prevention. We collected data related to the patients' demographic characteristics, history of chronic diseases and lifestyle factors in 2258 patients with primary hypertension. Logistic regression models based on odds ratio (OR) with their associated 95% confidence interval (CI) were used to estimate an independent effect of homocysteine (Hcy) on the risk of stroke but also include the interactions between Hcy and other risk factors. Hcy was associated with an increased OR of the risk of stroke in both hypertension patients (OR, 1.027; 95% CI, 1.016-1.038; P < 0.001) and H-type hypertension patients (OR, 1.026; 95% CI, 1.014-1.037; P < 0.001), after adjustment for potential confounding factors. Among the hypertension participants, three tests of interactions between Hcy and other risk factors were statistically significant: sex, systolic blood pressure and diastolic blood pressure. In conclusion, complexities of the interactions of Hcy stratified by sex and blood pressure need to be considered in predicting overall risk and selecting certain treatments for stroke prevention.

Abstract
BACKGROUND With rapid economic development, urbanization, and an aging population, cardiovascular diseases (CVDs) have become the leading cause of death in China. OBJECTIVES The aim of this study was to provide a comprehensive review on the prevalence, awareness, treatment, and control of hypertension (HTN) as well as blood pressure (BP)-related morbidity and mortality of CVD in Chinese adults over time. FINDINGS The prevalence of HTN in China is high and increasing. Recent estimates are variable but indicate 33.6% (35.3% in men and 32% in women) or 335.8 million (178.6 million men and 157.2 million women) of the Chinese adult population had HTN in 2010, which represents a significant increase from previous surveys. BP-related CVD remains the leading cause of death in Chinese adults, with stroke being the predominant cause of cardiovascular deaths. Of those with HTN, 33.4% (30.4% in men and 36.7% in women) were aware of their condition, 23.9% (20.6% in men and 27.7% in women) were treated, and only 3.9% (3.5% in men and 4.3% in women) were controlled to the currently recommended target of BP <140/90 mm Hg. Awareness and treatment of HTN have improved over time, but HTN control has not. Geographic differences in the prevalence, awareness, treatment, and control of HTN are evident, both in terms of a north-south gradient and urban-rural disparity. CONCLUSIONS The prevalence of HTN is high and increasing, while the control rate is low in Chinese adults. Combatting HTN and BP-related morbidity and mortality will require a comprehensive approach at national and local levels. The major challenge moving forward is to develop and implement effective, practical, and sustainable prevention and treatment strategies in China.

Abstract
Antihypertensive treatment has beneficial effects in the elderly. Surveying the situation of blood pressure in the elderly is quite important for planning strategies to manage elderly hypertensives. The aim of the present study was to investigate changes in blood pressure in the elderly over the past 15 years.As part of a physical check-up program between 2001 and 2015, 29,363 elderly participants (≥65 years of age) attended and were enrolled in the present study. The characteristics of the participants in each year were analyzed cross-sectionally and the results were compared over the 15 years. Changes in blood pressure, hypertension prevalence, and treatment rates, and the rate of reaching target blood pressure in the elderly were investigated.The prevalence of hypertension during the study period increased with increasing participant age. However, both the treatment rate and the rate of reaching target blood pressure in treated subjects improved. The blood pressure of treated hypertensive elderly subjects decreased from 146.1/83.0 to 130.6/75.4 mm Hg, and the reduction was most evident after revision of Japanese Society of Hypertension guidelines regarding target blood pressure in elderly hypertensives. Blood pressure in the entire cohort of elderly subjects decreased from 133.8/78.4 mm Hg in 2001 to 127.9/74.6 mm Hg in 2015.Blood pressure in elderly subjects had decreased over the 15-year study period primarily due to reductions in blood pressure in elderly hypertensive patients on medication. Guidelines for the treatment of hypertension have had a beneficial effect on the management of hypertension in the elderly.

Abstract
BACKGROUND Hypertension is an important risk factor for adverse cardiovascular events including stroke, myocardial infarction, heart failure and renal failure. The main goal of treatment is to reduce these events. Systematic reviews have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older. We wanted to know what the effects of therapy are in people 18 to 59 years of age. OBJECTIVES To quantify antihypertensive drug effects on all-cause mortality in adults aged 18 to 59 years with mild to moderate primary hypertension. To quantify effects on cardiovascular mortality plus morbidity (including cerebrovascular and coronary heart disease mortality plus morbidity), withdrawal due adverse events and estimate magnitude of systolic blood pressure (SBP) and diastolic blood pressure (DBP) lowering at one year. SEARCH METHODS The Cochrane Hypertension Information Specialist searched the following databases for randomized controlled trials up to January 2017: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We contacted authors of relevant papers regarding further published and unpublished work. SELECTION CRITERIA Randomized trials of at least one year' duration comparing antihypertensive pharmacotherapy with a placebo or no treatment in adults aged 18 to 59 years with mild to moderate primary hypertension defined as SBP 140 mmHg or greater or DBP 90 mmHg or greater at baseline, or both. DATA COLLECTION AND ANALYSIS The outcomes assessed were all-cause mortality, total cardiovascular (CVS) mortality plus morbidity, withdrawals due to adverse events, and decrease in SBP and DBP. For dichotomous outcomes, we used risk ratio (RR) with 95% confidence interval (CI) and a fixed-effect model to combine outcomes across trials. For continuous outcomes, we used mean difference (MD) with 95% CI and a random-effects model as there was significant heterogeneity. MAIN RESULTS The population in the seven included studies (17,327 participants) were predominantly healthy adults with mild to moderate primary hypertension. The Medical Research Council Trial of Mild Hypertension contributed 14,541 (84%) of total randomized participants, with mean age of 50 years and mean baseline blood pressure of 160/98 mmHg and a mean duration of follow-up of five years. Treatments used in this study were bendrofluazide 10 mg daily or propranolol 80 mg to 240 mg daily with addition of methyldopa if required. The risk of bias in the studies was high or unclear for a number of domains and led us to downgrade the quality of evidence for all outcomes.Based on five studies, antihypertensive drug therapy as compared to placebo or untreated control may have little or no effect on all-cause mortality (2.4% with control vs 2.3% with treatment; low quality evidence; RR 0.94, 95% CI 0.77 to 1.13). Based on 4 studies, the effects on coronary heart disease were uncertain due to low quality evidence (RR 0.99, 95% CI 0.82 to 1.19). Low quality evidence from six studies showed that drug therapy may reduce total cardiovascular mortality and morbidity from 4.1% to 3.2% over five years (RR 0.78, 95% CI 0.67 to 0.91) due to reduction in cerebrovascular mortality and morbidity (1.3% with control vs 0.6% with treatment; RR 0.46, 95% CI 0.34 to 0.64). Very low quality evidence from three studies showed that withdrawals due to adverse events were higher with drug therapy from 0.7% to 3.0% (RR 4.82, 95% CI 1.67 to 13.92). The effects on blood pressure varied between the studies and we are uncertain as to how much of a difference treatment makes on average. AUTHORS' CONCLUSIONS Antihypertensive drugs used to treat predominantly healthy adults aged 18 to 59 years with mild to moderate primary hypertension have a small absolute effect to reduce cardiovascular mortality and morbidity primarily due to reduction in cerebrovascular mortality and morbidity. All-cause mortality and coronary heart disease were not reduced. There is lack of good evidence on withdrawal due to adverse events. Future trials in this age group should be at least 10 years in duration and should compare different first-line drug classes and strategies.

Abstract
BACKGROUND High blood pressure is an important public health problem because of associated risks of stroke and cardiovascular events. Antihypertensive drugs are often used in the belief that lowering blood pressure will prevent cardiac events, including myocardial infarction and sudden death (death of unknown cause within one hour of the onset of acute symptoms or within 24 hours of observation of the patient as alive and symptom free). OBJECTIVES To assess the effects of antihypertensive pharmacotherapy in preventing sudden death, non-fatal myocardial infarction and fatal myocardial infarction among hypertensive individuals. SEARCH METHODS We searched the Cochrane Hypertension Specialised Register (all years to January 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (2016, Issue 1), Ovid MEDLINE (1946 to January 2016), Ovid EMBASE (1980 to January 2016) and ClinicalTrials.gov (all years to January 2016). SELECTION CRITERIA All randomised trials evaluating any antihypertensive drug treatment for hypertension, defined, when possible, as baseline resting systolic blood pressure of at least 140 mmHg and/or resting diastolic blood pressure of at least 90 mmHg. Comparisons included one or more antihypertensive drugs versus placebo, or versus no treatment. DATA COLLECTION AND ANALYSIS Review authors independently extracted data. Outcomes assessed were sudden death, fatal and non-fatal myocardial infarction and change in blood pressure. MAIN RESULTS We included 15 trials (39,908 participants) that evaluated antihypertensive pharmacotherapy for a mean duration of follow-up of 4.2 years. This review provides moderate-quality evidence to show that antihypertensive drugs do not reduce sudden death (risk ratio (RR) 0.96, 95% confidence interval (CI) 0.81 to 1.15) but do reduce both non-fatal myocardial infarction (RR 0.85, 95% CI 0.74, 0.98; absolute risk reduction (ARR) 0.3% over 4.2 years) and fatal myocardial infarction (RR 0.75, 95% CI 0.62 to 0.90; ARR 0.3% over 4.2 years). Withdrawals due to adverse effects were increased in the drug treatment group to 12.8%, as compared with 6.2% in the no treatment group. AUTHORS' CONCLUSIONS Although antihypertensive drugs reduce the incidence of fatal and non-fatal myocardial infarction, they do not appear to reduce the incidence of sudden death. This suggests that sudden cardiac death may not be caused primarily by acute myocardial infarction. Continued research is needed to determine the causes of sudden cardiac death.

Abstract
BACKGROUND The benefits of blood pressure lowering treatment for prevention of cardiovascular disease are well established. However, the extent to which these effects differ by baseline blood pressure, presence of comorbidities, or drug class is less clear. We therefore performed a systematic review and meta-analysis to clarify these differences. METHOD For this systematic review and meta-analysis, we searched MEDLINE for large-scale blood pressure lowering trials, published between Jan 1, 1966, and July 7, 2015, and we searched the medical literature to identify trials up to Nov 9, 2015. All randomised controlled trials of blood pressure lowering treatment were eligible for inclusion if they included a minimum of 1000 patient-years of follow-up in each study arm. No trials were excluded because of presence of baseline comorbidities, and trials of antihypertensive drugs for indications other than hypertension were eligible. We extracted summary-level data about study characteristics and the outcomes of major cardiovascular disease events, coronary heart disease, stroke, heart failure, renal failure, and all-cause mortality. We used inverse variance weighted fixed-effects meta-analyses to pool the estimates. RESULTS We identified 123 studies with 613,815 participants for the tabular meta-analysis. Meta-regression analyses showed relative risk reductions proportional to the magnitude of the blood pressure reductions achieved. Every 10 mm Hg reduction in systolic blood pressure significantly reduced the risk of major cardiovascular disease events (relative risk [RR] 0·80, 95% CI 0·77-0·83), coronary heart disease (0·83, 0·78-0·88), stroke (0·73, 0·68-0·77), and heart failure (0·72, 0·67-0·78), which, in the populations studied, led to a significant 13% reduction in all-cause mortality (0·87, 0·84-0·91). However, the effect on renal failure was not significant (0·95, 0·84-1·07). Similar proportional risk reductions (per 10 mm Hg lower systolic blood pressure) were noted in trials with higher mean baseline systolic blood pressure and trials with lower mean baseline systolic blood pressure (all ptrend>0·05). There was no clear evidence that proportional risk reductions in major cardiovascular disease differed by baseline disease history, except for diabetes and chronic kidney disease, for which smaller, but significant, risk reductions were detected. β blockers were inferior to other drugs for the prevention of major cardiovascular disease events, stroke, and renal failure. Calcium channel blockers were superior to other drugs for the prevention of stroke. For the prevention of heart failure, calcium channel blockers were inferior and diuretics were superior to other drug classes. Risk of bias was judged to be low for 113 trials and unclear for 10 trials. Heterogeneity for outcomes was low to moderate; the I(2) statistic for heterogeneity for major cardiovascular disease events was 41%, for coronary heart disease 25%, for stroke 26%, for heart failure 37%, for renal failure 28%, and for all-cause mortality 35%. INTERPRETATION Blood pressure lowering significantly reduces vascular risk across various baseline blood pressure levels and comorbidities. Our results provide strong support for lowering blood pressure to systolic blood pressures less than 130 mm Hg and providing blood pressure lowering treatment to individuals with a history of cardiovascular disease, coronary heart disease, stroke, diabetes, heart failure, and chronic kidney disease.

Abstract
AIM To evaluate the effectiveness of antihypertensives in reducing neurocognitive outcomes in elderly patients. PATIENTS & METHODS We conducted a systematic literature search of randomized trials in which hypertensive patients with a mean age ≥65 years received antihypertensive or control treatment. Outcomes were stroke, transient ischemic attack, cognitive decline and dementia. We included 14 trials for meta-analysis. RESULTS Compared to placebo, antihypertensive treatment reduced the risk of stroke (RR: 0.67 [95% CI: 0.57-0.79]). Reduced risk was significant for transient ischemic attack, fatal stroke, nonfatal stroke and total stroke. There were insufficient data to compare individual agents. CONCLUSION Antihypertensive treatment is associated with a significant reduction in stroke in elderly individuals. Reductions in dementia and cognitive decline were not significant; however, there was short follow-up. Comparative effectiveness evidence is limited.

Abstract
OBJECTIVES To assess the blood pressure-lowering efficacy and tolerability of perindopril/amlodipine fixed-dose combinations in Chinese patients with mild-to-moderate essential hypertension not adequately controlled with monotherapy alone. METHODS In 2 separate double-blind studies, patients received a 4-week run-in monotherapy of amlodipine 5 mg or perindopril 4 mg, respectively. Those whose blood pressure was uncontrolled were then randomized to receive the fixed-dose combination of perindopril 5 mg/amlodipine 5 mg (Per/Amlo group) or remain on the monotherapy for 8 weeks. Patients who were uncontrolled at the week 8 (W8) visit were up-titrated for the Per/Amlo combination, or received additional treatment if on monotherapy, for a further 4 weeks. The main efficacy assessment was at 8 weeks. RESULTS After 8 weeks, systolic blood pressure (SBP; primary criterion) was statistically significantly lower in the Per/Amlo group (vs. Amlo 5 mg, p = 0.0095; vs. Per 4 mg, p < 0.0001). Uncontrolled patients at W8 who received an up-titration of the Per/Amlo combination showed a further SBP reduction. These changes were mirrored by reassuring reductions in diastolic blood pressure. The fixed-dose combinations were well tolerated. CONCLUSIONS Single-pill combinations of perindopril and amlodipine provide hypertensive patients with a convenient and effective method of reducing blood pressure.

Abstract
According to the 4th National Nutrition and Health Survey in 2002, the prevalence of hypertension in China was 18.8%. Although there are no recent updated nationwide data, it is believed that the prevalence of hypertension has increased substantially in the past decade up to more than 200 million hypertensive patients in the populous country of China. To fight against the growing risk of hypertension, three Chinese hypertension guidelines were compiled in the past two decades, in 1999, 2005, and 2011. The current guidance document for the management of hypertension was named '2010 Chinese hypertension guideline', but it was actually published in 2011. In this guideline, all five classes of antihypertensive drugs were recommended as possible initial and maintenance therapy. The goal of treatment was a systolic/diastolic blood pressure below 140/90 mm Hg in general, 130/80 mm Hg in various groups of high-risk patients, and 150/90 mm Hg in the elderly (≥65 years). With the recent publication of several national and international hypertension guidelines, the Chinese guideline is now under discussion for updating.

Abstract
Hypertension is a frequent condition among individuals over 65 years of age worldwide and is one of the most important risk factors for cardiovascular (CV) disease. Effective drug treatment of elderly hypertensives is usually associated with a marked reduction in CV morbidity and mortality. Among the different classes of antihypertensive agents, angiotensin receptor blockers (ARBs) and ACE-inhibitors are supposed to provide the best efficacy in lowering blood pressure (BP) and protecting target organ damage while featuring a good tolerability profile. However, up to date, few randomized clinical studies have directly compared the activity and safety of ARBs and ACE-inhibitors in elderly hypertensive patients. Aim of this review of published and unpublished pooled data from two recent randomized, double-blind, controlled trials, is to offer a comprehensive head-to-head comparison of the antihypertensive efficacy of the ARB olmesartan medoxomil vs. the ACE-inhibitor ramipril in a large study population including more than 1,400 hypertensive subjects aged 65-89 years with mild-to-moderate essential hypertension. The efficacy of the two drugs was separately evaluated in subgroups of patients classified according to the presence of metabolic syndrome, reduced renal function, CV risk level, gender, class of age, type of arterial hypertension and previous antihypertensive treatments. Olmesartan showed a greater efficacy than ramipril both in terms of clinic BP reduction and rate normalization. Olmesartan appeared significantly superior to ramipril in providing a more homogeneous and long-lasting 24-h BP control and maintaining an effective antihypertensive action in the last 6-h period from drug intake. In subgroups of patients with additional clinical conditions, olmesartan gave comparable, and in some cases greater, BP responses than those achieved with the ACE-inhibitor. The incidence of adverse events was similar for both drugs. Olmesartan may thus represent an effective alternative to ACE-inhibitors among first-line drug treatments for hypertension in older people.

Abstract
Hypertension is an important modifiable risk factor for cardiovascular disease; its prevention and treatment currently represent major health concerns around the world, especially in western countries. Effective, well-tolerated drugs such as dihydropyridine calcium channel blockers, to be used either alone or in combination treatments, play a key role in reducing cardiovascular morbidity and mortality. The extended-release formulation of nifedipine given once daily provides a relatively constant concentration profile and has proved to be effective in reducing blood pressure values. In the International Nifedipine gastrointestinal therapeutic system Study: Intervention as a Goal in Hypertension Treatment (INSIGHT) study, it was demonstrated that nifedipine confers cardiovascular protection as effectively as diuretics in high-risk patients, with a smaller incidence of adverse metabolic consequences. Furthermore, two INSIGHT substudies demonstrated that nifedipine prevents the progression of carotid atherosclerosis and reduces the worsening of coronary calcifications, supporting the use of calcium channel blockers in hypertensive patients--especially those at high cardiovascular risk. This review discusses the existing clinical evidence supporting the use of nifedipine in the treatment of hypertension.

Abstract
Hypertension is the most powerful risk factor for stroke. Antihypertensive drug treatment reduces the incidence of stroke. In a meta-analysis of actively controlled trials, calcium-channel blockers, including (-8%; p = 0.07) or excluding verapamil (-10%; p = 0.02), as well as angiotensin Type 1 receptor blockers (-24%; p = 0.0002) resulted in better stroke prevention than the old drugs (diuretics or beta-blockers), whereas the opposite trend was observed for angiotensin-converting enzyme inhibitors (+10%; p = 0.03). An overview of six trials conducted in patients with a history of cerebrovascular disease demonstrated that blood pressure-lowering therapy reduced stroke recurrence by 25% (p = 0.004). A meta-regression analysis showed that within-trial differences in systolic blood pressure accounted for the prevention of stroke in most trials. This finding was corroborated by the recently published Valsartan Antihypertensive Long-term Use Evaluation trial.

Effects of antihypertensive treatment in Asian populations: a meta-analysis of prospective randomized controlled studies (CARdiovascular protectioN group in Asia: CARNA). ACTA ACUST UNITED AC 2013; 8:103-16. [PMID: 24157055 DOI: 10.1016/j.jash.2013.09.002] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2013] [Revised: 09/09/2013] [Accepted: 09/13/2013] [Indexed: 12/31/2022]
Abstract
To examine the effects of antihypertensive treatment on cardiovascular disease (CVD) in Asian populations, we systematically evaluated prospective randomized studies carried out in Asia (1991-2013). We identified 18 trials with 23,215 and 21,986 hypertensive patients in the intervention (ie, strict blood pressure [BP] lowering or add-on treatment) and reference groups, respectively (mean age, 65 years; follow-up duration, 3.2 years). Analysis was performed through 1) first subgroup: eight trials that compared active antihypertensive treatment with placebo or intensive with less intensive BP control and 2) second subgroup: 10 trials that compared different antihypertensive treatments. In the first subgroup analysis, BP was reduced from 160.3/87.3 mm Hg to 140.2/78.4 mm Hg in the intervention group with a -6.7/-2.2 mm Hg (P < .001) greater BP reduction than the reference group. Compared with the reference group, the intervention group had a lower risk of composite CVD events (odd ratio [OR], 0.73; 95% confidence interval [CI], 0.66-0.81), myocardial infarction (OR, 0.79; 95% CI, 0.63-1.0), stroke (OR, 0.71; 95% CI, 0.63-0.80), and CVD mortality (OR, 0.81; 95% CI, 0.68-0.97; all P ≤ .05). In the second subgroup analysis, no difference was found for any outcome between renin-angiotensin blockers and calcium-channel blockers or diuretics. The meta-regression line among the 18 trials indicated that a 10 mm Hg reduction in systolic BP was associated with a reduced risk for composite CVD events (-39.5%) and stroke (-30.0%). Our meta-analysis shows a benefit when a BP target of less than 140/80 mm Hg is achieved in Asian hypertensives. BP reduction itself, regardless of BP lowering agents, is important for achieving CVD risk reduction.

Abstract
This study was performed to investigate whether intensive antihypertensive treatment with achieved blood pressure (BP) ≤140/90 mm Hg, as compared with standard treatment with achieved BP ≤150/90 mm Hg, could further improve cardiovascular outcomes in Chinese hypertensive patients older than 70 years. A total of 724 participants were randomly assigned to intensive or standard antihypertensive treatment. After a mean follow-up of 4 years, the mean achieved BP was 135.7/76.2 mm Hg in the intensive treatment group and 149.7/82.1 mm Hg in the standard treatment group. The visit-to-visit variability in systolic BP and diastolic BP was lower in the intensive group than that in the standard group. Intensive antihypertensive treatment, compared with the standard treatment, decreased total and cardiovascular mortality by 41.7% and 50.3%, respectively, and reduced fatal/nonfatal stroke by 42.0% and heart failure death by 62.7%. Cox regression analysis indicated that the mean systolic BP (P=.020; 95% confidence interval, 1.006-1.069) and the standard deviation of systolic BP (P=.033; 95% confidence interval, 1.006-1.151) were risk factors for cardiovascular endpoint events. Intensive antihypertensive treatment with achieved 136/76 mm Hg was beneficial for Chinese hypertensive patients older than 70 years. Long-term visit-to-visit variability in systolic BP was positively associated with the incidence of cardiovascular events.

Abstract
BACKGROUND Hypertension is a major risk factor for the development of stroke. It is well known that lowering blood pressure decreases the risk of stroke in people with moderate to severe hypertension. However, the specific effects of calcium channel blockers (CCBs) against stroke in patients with hypertension as compared to no treatment and other antihypertensive drug classes are not known. METHODS AND FINDINGS This systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated CCBs effect on stroke in patients with hypertension in studies of CCBs versus placebo, angiotensin-converting-enzyme inhibitors (ACEIs), β-adrenergic blockers, and diuretics. The PUBMED, MEDLINE, EMBASE, OVID, CNKI, MEDCH, and WANFANG databases were searched for trials published in English or Chinese during the period January 1, 1996 to July 31, 2012. A total of 177 reports were collected, among them 31 RCTs with 273,543 participants (including 130,466 experimental subjects and 143,077 controls) met the inclusion criteria. In these trials a total of 9,550 stroke events (4,145 in experimental group and 5,405 in control group) were reported. CCBs significantly decreased the incidence of stroke compared with placebo (OR = 0.68, 95% CI 0.61-0.75, p<1×10(-5)), β-adrenergic blockers combined with diuretics (OR = 0.89, 95% CI 0.83-0.95, p = 7×10(-5)) and β-adrenergic blockers (OR = 0.79, 95% CI 0.72-0.87, p<1×10(-5)), statistically significant difference was not found between CCBs and ACEIs (OR = 0.92, 95% CI 0.8-1.02, p = 0.12) or diuretics (OR = 0.95, 95% CI 0.84-1.07, p = 0.39). CONCLUSION In a pooled analysis of data of 31 RCTs measuring the effect of CCBs on stroke, CCBs reduced stroke more than placebo and β-adrenergic blockers, but were not different than ACEIs and diuretics. More head to head RCTs are warranted.

Abstract
In China, the prevalence of hypertension is currently 18.8 %, and a major risk factor for hypertension is unbalanced dietary sodium and potassium intakes. High dietary sodium intake may change the circadian rhythm of 24-h blood pressure, which is characterized by a higher nighttime blood pressure. The prevalence of isolated nighttime hypertension, defined as a nighttime blood pressure of at least 120 mm Hg systolic or 70 mm Hg diastolic and a daytime systolic/diastolic blood pressure less than 135/85 mm Hg, is higher in Chinese than in Europeans. The complications of hypertension are also different across ethnicities, being mainly stroke instead of myocardial infarction in Chinese. Lowering of blood pressure provides more protection against stroke than against myocardial infarction, and calcium channel blockers provide more protection against stroke than do other classes of antihypertensive drugs. Current Chinese hypertension guidelines recommend calcium channel blockers as the most suitable class of drugs of the five classes of antihypertensive drugs.

Abstract
According to the 4th National Nutrition and Health Survey in 2002, the prevalence of hypertension in China was 18.8%. Despite that, the treatment rate among hypertensive patients was 82%, the control rate remained low in persons with hypertension (6%), because of the low awareness in general (30%) and the low control rate among treated hypertensive patients (25%). One of the major reasons for the increasing prevalence of hypertension is unbalance of dietary sodium and potassium intakes. In the International Study of Macro/Micro-nutrients and Blood Pressure (INTERMAP), Chinese, compared with American, British, and Japanese populations, had highest dietary sodium intakes and lowest potassium intakes, leading to a two to three times higher sodium/potassium ratio. High dietary sodium intakes may change the circadian rhythm of 24 h blood pressure, which is characterized by a higher night-time blood pressure. Indeed, the prevalence of isolated night-time hypertension, defined as a night-time blood pressure of at least 120 mmHg systolic or 70 mmHg diastolic and a daytime systolic/diastolic blood pressure less than 135/85 mmHg, was higher in Chinese than in Europeans. The complications of hypertension are also different across ethnicities, being mainly stroke instead of myocardial infarction in Chinese. Blood pressure lowering provides more protection against stroke than myocardial infarction, and calcium channel blockers provide more protection against stroke than other classes of antihypertensive drugs. Current Chinese hypertension guidelines recommend calcium channel blockers as the first of the five classes of antihypertensive drugs for stage 1 and low-risk hypertension.

Abstract
Hypertension is a major modifiable risk factor for cardiovascular morbidity and mortality in diabetic patients. Guidelines recommend lowering blood pressure (BP) to less than 130/80 mmHg in diabetic patients. These recommendations are based on several studies in diabetic patients that showed the benefit of intensive BP control. However in all the studies the achieved BP was higher than 130/80 mmHg. Re-evaluation of earlier studies, as well as more recently accumulated data suggest that intensive BP control is associated with a significant reduction in all-cause mortality and stroke rate, but with no benefit for other microvascular or macrovascular (cardiac, renal and retinal) outcomes. Intensive BP control is associated with an increased risk of serious adverse effects, particularly for systolic BPs levels lower than 130 mmHg. When determining the target BP in diabetic patients one should balance the potential cerebrovascular protection against the increased risk of serious side effects, and the absence of benefit for other circulatory system. It seems therefore, that lowering BP to levels close to 130/80 mmHg should be the main goal of treatment in diabetic patients.

Abstract
Reports of adverse events in association with calcium-channel blockers led to heated controversy over the safety and efficacy of these drugs, as well as to panic among the general public. At the 1998 International Conference of Pharmacoepidemiology, four experts were asked to summarize, and draw lessons from, the controversy's development. We conducted our own review in order to provide a broader historical perspective on the subject and to present the discussants' views within the framework of additional published opinions. Several years after the controversy's onset, many uncertainties still remain about the merits of CCBs. Yet the media scare generated by a few studies might have been prevented had investigators placed greater emphasis, particularly in their reports to the media, on the limitations of their observational and meta-analytic designs. These studies, however, did call attention to the persistent use of CCBs for off-label indications, and the imperative to improve clinician prescribing practices. Moreover, they showed the pitfalls of reliance on surrogate endpoints, stressing the need for data on major clinical outcomes-with funding a responsibility of the pharmaceutical industry-before approving drugs destined for widespread, long-term use. Attention to these lessons will do us well as we evaluate emerging pharmacotherapies. Copyright (c) 2000 John Wiley & Sons, Ltd.

Abstract
BACKGROUND A majority of hypertensives require treatment with ≥2 antihypertensive therapies to achieve blood pressure (BP) goals. Single-pill combinations (SPC) may improve convenience and adherence to therapy and reduce health care resource use and costs. The antihypertensive effects of amlodipine and valsartan are well established. This study evaluated the efficacy and safety of amlodipine/valsartan 5/160 mg SPC for the treatment of hypertension in predominantly Chinese patients not adequately controlled on valsartan 160 mg alone. METHODS In this multicentre study (24 centres), adults with stage 1 or 2 hypertension not adequately controlled with valsartan monotherapy were randomised to receive double-blind amlodipine/valsartan 5/160 mg SPC or valsartan 160 mg once daily for 8 weeks. RESULTS The least-square mean change (standard error) from baseline to endpoint in mean sitting diastolic blood pressure (MSDBP) at trough, the primary efficacy variable, was -10.3 (0.39) mm Hg with amlodipine/valsartan and -6.6 (0.40) mm Hg with valsartan (difference: -3.7 [0.54] mm Hg, p<0.0001). The corresponding results for mean sitting systolic blood pressure (MSSBP) were -14.9 (0.61) mm Hg and -7.0 (0.61) mm Hg, respectively (difference: -7.9 [0.84] mm Hg, p<0.0001). A significantly greater proportion of patients achieved overall BP control (MSSBP/MSDBP<140/90 mm Hg) with combination therapy (61.3%) versus monotherapy (39.3%; p<0.0001). Both treatments were well tolerated. CONCLUSION Amlodipine/valsartan 5/160 mg SPC is a safe and effective therapy for lowering BP in predominantly Chinese adults with stage 1 or 2 hypertension not adequately controlled with valsartan 160 mg monotherapy.

Abstract
There are limited clinical trials examining the efficacy of antihypertensive drug combinations aimed at preventing cardiovascular events. Therefore, we designed a randomized controlled trial using amlodipine as the base drug of a multi-drug regimen, the Optimal Combination of Effective ANtihypertensives (OCEAN) Study, to determine the drug combination that is most efficacious in the prevention of cardiovascular events, such as stroke. The OCEAN Study is a collaborative study between Japan and China, enrolling 20 000 patients and following them for 3 to 4 years. A pilot study was conducted before the full-scale study to confirm the feasibility of the protocol and that the study groups and infrastructures could function properly. A total of 279 Japanese patients were enrolled from 57 participating medical institutions between June and December 2004. Two hundred and sixty-six patients (mean age: 65.9 years) were treated with amlodipine alone. One hundred and fifty-four of these patients (57.9%) did not reach the treatment targets (<140/90 mm Hg for the elderly and patients with cerebrovascular disease, <130/80 mm Hg for those with diabetes mellitus, chronic kidney disease or prior myocardial infarction) and a second agent was added. They were randomly allocated into three different treatment groups using a diuretic, a β-blocker or an angiotensin-converting enzyme inhibitor/angiotensin II receptor antagonist. The pilot study showed that the protocol was appropriate, and the inclusion of patients with slightly higher blood pressures was necessary to increase the randomization rate. It also confirmed that we organized properly functioning study groups and infrastructures.
