- Abstract
Background: The effects of pharmacological blood pressure lowering at normal or high-normal blood pressure ranges in people with or without pre-existing cardiovascular disease remains uncertain. We analysed individual participant data from randomised trials to investigate the effects of blood pressure lowering treatment on the risk of major cardiovascular events by baseline levels of systolic blood pressure. Methods: We did a meta-analysis of individual participant-level data from 48 randomised trials of pharmacological blood pressure lowering medications versus placebo or other classes of blood pressure-lowering medications, or between more versus less intensive treatment regimens, which had at least 1000 persons-years of follow-up in each group. Trials exclusively done with participants with heart failure or short-term interventions in participants with acute myocardial infarction or other acute settings were excluded. Data from 51 studies published between 1972 and 2013 were obtained by the Blood Pressure Lowering Treatment Trialists' Collaboration (Oxford University, Oxford, UK). We pooled the data to investigate the stratified effects of blood pressure-lowering treatment in participants with and without prevalent cardiovascular disease (ie, any reports of stroke, myocardial infarction, or ischaemic heart disease before randomisation), overall and across seven systolic blood pressure categories (ranging from <120 to ≥170 mm Hg). The primary outcome was a major cardiovascular event (defined as a composite of fatal and non-fatal stroke, fatal or non-fatal myocardial infarction or ischaemic heart disease, or heart failure causing death or requiring admission to hospital), analysed as per intention to treat. Findings: Data for 344 716 participants from 48 randomised clinical trials were available for this analysis. Pre-randomisation mean systolic/diastolic blood pressures were 146/84 mm Hg in participants with previous cardiovascular disease (n=157 728) and 157/89 m

IntroductionPrevious research from the Blood Pressure Lowering Treatment Trialists’ Collaboration (BPLTTC) and others has shown that pharmacological blood pressure (BP)- lowering substantially reduces the risk of major cardiovascular events, including ischaemic heart disease, heart failure and stroke. In this new phase, the aim is to conduct individual patient-level data (IPD) meta-analyses involving eligible BP-lowering randomised controlled trials (RCTs) to address uncertainties relating to efficacy and safety of BP-lowering treatment.Methods and analysisRCTs investigating the effect of pharmacological BP-lowering, with a minimum of 1000 patient-years of follow-up in each trial arm, are eligible. Our systematic review identified 100 potentially eligible trials. We requested their investigators/sponsors to contribute baseline, follow-up and outcomes data. As of June 2018, the collaboration has obtained data from 49 trials (n=315 046 participants), with additional data currently in the process of being transferred from four RCTs (n=34 642 participants). In addition, data harmonisation has commenced. Scientific activities of the collaboration are overseen by the Steering Committee with input from all collaborators. Detailed protocols for individual meta-analyses will be developed and registered on public platforms.Ethics and disseminationEthics approval has been obtained for this new and extended phase of the BPLTTC, the largest collaboration of de-identified IPD from RCTs. It offers an efficient and ethical manner of re-purposing existing data to answer clinically important questions relating to BP treatment as well as methodological questions relating to IPD meta-analyses. Among the immediate impacts will include reliable quantification of effects of treatment modifiers, such as baseline BP, age and prior disease, on both vascular and non-vascular outcomes. Analyses will further assess the impact of BP-lowering on important, but less well understood, outcomes, such as new-onset diabetes and renal disease. Findings will be published in peer-reviewed medical journals on behalf of the collaboration.

systolic visit-to-visit - Abstract
OBJECTIVE: High systolic blood pressure variability has been associated with an increased risk of cardiovascular events, and has been shown to be associated with an increased risk of cardiac events in the VALUE trial. In this analysis we aimed to assess if increased visit-to-visit variability in systolic blood pressure increased the risk of myocardial infarction or heart failure in the VALUE trial patient population. DESIGN AND METHOD: The VALUE trial was a randomised-controlled, double-masked investigation of valsartan versus amlodipine in patients 50 years or older with hypertension and high risk of cardiovascular events. Mean follow-up time was 4.2 years. We calculated the standard deviation (SD) of mean systolic blood pressure from visits 6 months onward, excluding patients with less than 3 visits, or patients with stroke or cardiac events during the first 6 months. In the pooled treatment arms, we grouped SD in quintiles and compared the risk of myocardial infarction and congestive heart failure (fatal/non-fatal events) in the highest and the lowest quintile, using a Cox regression model, adjusting for a number of prognostic variables, including randomised treatment and mean systolic blood pressure from 6 months onwards. RESULTS: Of 13.803 patients included, 503 (3.6%) experienced myocardial infarction and 489 (3.5%) experienced congestive heart failure. Compared to patients with the lowest variability, those in the highest quintile had an increased risk of myocardial infarction and congestive heart failure (HR 3.2, 95% CI 2.3-4.3, p

- Abstract
Background: Systolic blood pressure (BP) is a key predictor of cardiovascular events, but patients with peripheral artery disease (PAD) are rarely included in hypertension trials. The VALUE trial (Valsartan Antihypertensive Long-Term Use Evaluation) investigated the long-term effects of valsartan- or amlodipine-based treatments on cardiovascular outcomes in patients with hypertension with a high cardiovascular risk. The aim of this subanalysis was to clarify the relationship between achieved BP on treatment and cardiovascular outcomes in patients with hypertension with PAD., Methods: Patients were followed for 4 to 6 years, and BP was measured regularly. The primary end point was time to the first major adverse cardiovascular event, including myocardial infarction, stroke, cardiovascular death, and heart failure requiring hospitalization. Statistical analyses were performed using Cox regression, adjusting for various baseline covariates., Results: Of the 13 803 participants, 1898 (13.8%) had PAD. During a median follow-up of 4.5 years, patients with PAD had a 23% increased risk of major adverse cardiovascular events compared with patients without PAD. Patients with an achieved systolic BP <130 mm Hg and 130 to 139 mm Hg, compared with those with systolic BP ≥140 mm Hg, were associated with a decreased risk of a major adverse cardiovascular event (hazard ratio, 0.65 [95% CI, 0.43-0.97]; P =0.037; 0.85 [95% CI, 0.74-0.97]; P =0.016, respectively). Additionally, systolic BP <130 mm Hg was associated with a decreased risk of cardiovascular death (hazard ratio, 0.33 [95% CI, 0.12-0.92]; P =0.034). The incidence of the primary outcome did not differ between antihypertensive treatment regimens ( P =0.365)., Conclusions: Our results indicate that more intensive BP control is associated with a reduction in cardiovascular morbidity and mortality in patients with hypertensive PAD., Competing Interests: Disclosures G.

- Abstract
Background: Approximately 40% of people with hypertension have left ventricular hypertrophy (LVH) detected by ECG or echocardiography. Because patients with LVH have poor myocardial microcirculation, they may be too sensitive to lowering systolic blood pressure (SBP) too much due to a lack of myocardial perfusion pressure. We aimed to investigate whether the average achieved SBP <130 mm Hg may cause harm in patients with LVH in the Valsartan Antihypertensive Long-Term Use Evaluation trial (VALUE)., Methods: Of the 15 245 VALUE participants, we identified 13 803 patients without cardiovascular events during the first 6 months after randomization. Of these, 2458 patients had electrocardiographic LVH (ECG-LVH). Cox analyses adjusted for age, gender, and baseline variables compared cardiac and all-cause mortality and other prespecified end points for patients who achieved average SBP 130 to 139 mm Hg (No-LVH group n=4863; ECG-LVH group n=929) and <130 mm Hg (No-LVH group n=2107; ECG-LVH group n=305). Reference groups were patients who achieved average SBP ≥140 mm Hg following the first excluded 6 months (No-LVH group n=4375; ECG-LVH group n=1224)., Results: The No-LVH group achieving average SBP <130 mm Hg had a significantly lower incidence of several cardiovascular end points. The ECG-LVH group achieving average SBP <130 mm Hg had higher cardiac mortality (hazard ratio, 1.98 [95% CIs, 1.06-3.70]; P =0.032) and all-cause mortality (hazard ratio, 1.74 [95% CIs, 1.17-2.60]; P =0.007), and SBP <130 mm Hg was not associated with a reduction in any end point., Conclusions: Our findings may be seen as a signal that caution is warranted when treating middle-aged and older patients with electrocardiographic or echocardiographic LVH to SBP <130 mm Hg., Competing Interests: Disclosures Dr Mancia reports honoraria from Astra Zeneca, Boehringer Ingelheim, Daiichi Sankyo, Medtronic, Menarini Group, Merck, Novartis, Recordati, Sandoz, Sanofi, and Servier outside the present work.

- Abstract
Purpose: Event-based clinical outcome trials have shown limited evidence to support guidelines recommendations to lower blood pressure (BP) to <130/80 mmHg in middle-aged and elderly hypertensive patients with diabetes mellitus or with general high cardiovascular (CV) risk. We addressed this issue by post-hoc analysing the risk of CV events in patients who participated in the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial and compared the hypertensive patients with type 2 diabetes mellitus with all high-risk hypertensive patients., Materials and Methods: Patients were divided into 4 groups according to the proportion of on-treatment visits before the occurrence of an event (<25% to ≥75%) in which BP was reduced to <140/90 or <130/80 mmHg. Patients with diabetes mellitus ( n = 5250) were compared with the entire VALUE population with high CV risk ( n = 15,245)., Results: After adjustments for baseline differences between groups, a reduction in the proportion of visits in which BP was reduced to <140/90 mmHg, but not to <130/80 mmHg, was accompanied by a progressive increase in the risk of CV morbidity and mortality as well as stroke, myocardial infarction and heart failure in both diabetes mellitus and in all high-risk patients. Target BP <130/80 mmHg reduced stroke risk in the main population but not in the diabetes mellitus patients. Patients with diabetes mellitus had higher event rates for the primary cardiac endpoint and all-cause mortality driven by a higher rate of heart failure., Conclusion: In the high-risk hypertensive patients of the VALUE trial achieving more frequently BP <140/90 mmHg, but not <130/80 mmHg, showed principally the same protective effect on overall and cause-specific cardiovascular outcomes in patients with diabetes mellitus and in the general high-risk hypertensive population.

- Abstract
Purpose: Available data of event-based clinical outcomes trials show that little evidence supports the guidelines recommendations to lower blood pressure (BP) to <130/80 mmHg in middle-aged and elderly people with type 2 diabetes mellitus and hypertension. We addressed this issue by post-hoc analysing the risk of cardiovascular (CV) events in mostly elderly high-risk hypertensive patients with type 2 diabetes mellitus participating in the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial., Material and Methods: Patients ( n = 5250) were divided into 4 groups according to the proportion of on-treatment visits before the occurrence of an event (<25% to ≥ 75%) in which BP was reduced to <140/90 or <130/80 mmHg., Results: After adjustment for baseline demographic differences between groups, a reduction in the proportion of visits in which BP achieved <140/90 mmHg accompanied a progressive increase in the risk of CV mortality and morbidity as well as of cause-specific events such as stroke, myocardial infarction and heart failure. A progressive reduction in the proportion of visits in which BP was reduced <130/80 mmHg did not have any effect on CV risks., Conclusion: In mostly elderly high-risk hypertensive patients with type 2 diabetes mellitus participating in the VALUE trial, achieving more frequently BP <140/90 mmHg showed a marked protective effect on overall and all cause-specific cardiovascular outcomes. This was not the case for a more frequent achievement of the more intensive BP target, i.e. <130/80 mmHg.

- Abstract
Blood pressure-lowering drugs have different blood pressure-lowering profiles. We studied if differences in blood pressure mean and variability can explain the differences in risks of cardiovascular events and death among 15 245 high-risk hypertensive patients randomized to valsartan or amlodipine and followed for 4.2 years in the VALUE trial (Valsartan Antihypertensive Long-Term Use Evaluation). We selected patients with ≥3 visits and performed Cox regression analyses, defining mean blood pressure as a time-dependent covariate and visit-to-visit and within-visit blood pressure variability as the SD. Of 14 996 eligible patients, participants in the valsartan group had higher systolic mean blood pressure by 2.2 mm Hg, higher visit-to-visit systolic variability by 1.4 mm Hg, and higher within-visit systolic variability by 0.2 mm Hg ( P values <0.0001). The higher risks of myocardial infarction and stroke in the valsartan group was attenuated after adjustment for mean and variability of systolic blood pressure, from HR 1.19 (95% CI, 1.02-1.39) to 1.11 (0.96-1.30) and from HR 1.13 (0.96-1.33) to 1.00 (0.85-1.18), respectively. The lower risk of congestive heart failure in the valsartan group was accentuated after adjustment, from HR 0.86 (0.74-1.00) to 0.76 (0.65-0.89). A smaller effect was seen on risk of death, from 1.01 (0.92-1.12) to 0.94 (0.85-1.04). In conclusion, the higher risks of myocardial infarction and stroke in patients randomized to valsartan versus amlodipine were related to the drugs' different blood pressure modulating profiles. The risk of congestive heart failure with valsartan was lower, independent of the less favorable blood pressure modulating profile.

- Abstract
Purpose: Blood pressure variability is associated with traditional cardiovascular risk factors, but little is known about the association with atrial fibrillation. We compared blood pressure variability in patients with and without atrial fibrillation using data from the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial., Materials and Methods: The VALUE trial was a randomised-controlled trial of valsartan versus amlodipine in patients with hypertension and high cardiovascular risk, followed for 4.2 years (mean). For the present analysis we included patients with electrocardiogram at baseline and during follow-up, and ≥3 visits from 6 months onwards. We compared standard deviation (SD) of all blood pressures within each visit averaged across all visits (within-visit variability) and of mean blood pressure at each visit (visit-to-visit variability) in patients with and without atrial fibrillation at baseline. We similarly compared patients who developed non-persistent or persistent atrial fibrillation during follow-up with those who did not, using t-tests, ANOVA and linear regression., Results: Of 15,245 patients in the VALUE trial, 13,827 were eligible for analysis. SD of visit-to-visit systolic blood pressure was not significantly different between patients with and without atrial fibrillation at baseline (mean difference 0.3 mm Hg, p = 0.4), but significantly higher in patients with incident non-persistent or persistent atrial fibrillation during follow-up than in those who never developed atrial fibrillation (differences 1.2 and 1.8 mm Hg, respectively, p-values <0.0001). Associations with non-persistent and persistent atrial fibrillation were confirmed in linear regression models (p-values <0.0001). SD of within-visit systolic blood pressure was not significantly different between patients with and without atrial fibrillation at baseline (p = 0.4) but significantly higher in patients with persistent atrial fibrillation during follow-up (p = 0.04)., Conclusion: In patients treated for hypertension, atrial fibrillation was not associated with increased blood pressure variability, but blood pressure variability was higher in those who developed atrial fibrillation during follow-up.

- Abstract
Aims: Blood pressure variability is associated with increased risk of cardiovascular events, particularly in high-risk patients. We assessed if variability was associated with increased risk of cardiovascular events and death in hypertensive patients at different risk levels., Methods and Results: The Valsartan Antihypertensive Long-term Use Evaluation trial was a randomized controlled trial of valsartan vs. amlodipine in patients with hypertension and different risks of cardiovascular events, followed for a mean of 4.2 years. We calculated standard deviation (SD) of mean systolic blood pressure from visits from 6 months onward in patients with ≥3 visits and no events during the first 6 months. We compared the risk of cardiovascular events in the highest and lowest quintile of visit-to-visit blood pressure variability, using Cox regression. For analysis of death, variability was analysed as a continuous variable. Of 13 803 patients included, 1557 (11.3%) had a cardiovascular event and 1089 (7.9%) died. Patients in the highest quintile of SD had an increased risk of cardiovascular events [hazard ratio (HR) 2.1, 95% confidence interval (95% CI) 1.7-2.4; P < 0.0001], and a 5 mmHg increase in SD of systolic blood pressure was associated with a 10% increase in the risk of death (HR 1.10, 95% CI 1.04-1.17; P = 0.002). Associations were stronger among younger patients and patients with lower systolic blood pressure, and similar between patients with different baseline risks, except for higher risk of death among patients with established cardiovascular disease., Conclusion: Higher visit-to-visit systolic blood pressure variability is associated with increased risk of cardiovascular events in patients with hypertension, irrespective of baseline risk of cardiovascular events. Associations were stronger in younger patients and in those with lower mean systolic blood pressure.
