Abstract
INTRODUCTION The Attempted Suicide Short Intervention Program (ASSIP) is a brief psychotherapeutic intervention, and a pivotal study found it to be remarkably effective in reducing repeat suicide attempts. OBJECTIVE To compare the effectiveness of ASSIP to crisis counseling (CC) in a randomized clinical trial (ISRCTN13464512). METHODS Adult patients receiving treatment for a suicide attempt in a Helsinki City general hospital emergency room in 2016-2017 were eligible to participate. We excluded psychotic or likely non-adherent substance-abusing or substance-dependent patients. Eligible patients (n = 239) were randomly allocated to one of two interventions. (a) ASSIP comprised three visits, including a videotaped first visit, a case formulation, and an individualized safety plan, plus letters from the therapist every 3 months for 1 year, and then, every 6 months for the next year. (b) CC typically involved 2-5 (median 3) face-to-face individual sessions. In addition, all participants received their usual treatment. One and 2 years after baseline, information related to participants' suicidal thoughts and attempts, and psychiatric treatment received was collected via telephone and from medical and psychiatric records. RESULTS Among randomized patients, two-thirds initiated either ASSIP (n = 89) or CC (n = 72), with 73 (82%) completing ASSIP and 58 (81%) CC. The proportion of patients who attempted suicide during the 2-year follow-up did not differ significantly between ASSIP and CC (29.2% [26/89] vs. 35.2% [25/71], OR 0.755 [95% Cl 0.379-1.504]). CONCLUSIONS We found no difference in the effectiveness of the two brief interventions to prevent repeat suicide attempts.

Abstract
PURPOSE Education and feedback on hypertension management has been associated with improved hypertension control. This study aimed to assess the effectiveness of such interventions to reduce the risk of stroke and cardiovascular events. MATERIALS AND METHODS Individuals ≥18 years with a blood pressure (BP) recording in Västerbotten or Södermanland County during the study period 2001 to 2009 were included in 108 serial cohort studies, each with 24 months follow-up. The primary outcome was risk of first-ever stroke in Västerbotten County (intervention) compared with Södermanland County (control). Secondary outcomes were first-ever major adverse cardiovascular event (MACE), myocardial infarction, and heart failure, as well as all-cause and cardiovascular mortality. All outcomes were analysed using time-to-event data included in a Cox proportional hazards model adjusted for age, sex, hypertension, diabetes, coronary artery disease, atrial fibrillation, systolic BP at inclusion, marital status, and disposable income. RESULTS A total of 121 365 individuals (mean [SD] age at inclusion 61.7 [16.3] years; 59.9% female; mean inclusion BP 142.3/82.6 mmHg) in the intervention county were compared to 131 924 individuals (63.6 [16.2] years; 61.2% female; 144.1/81.1 mmHg) in the control county. A first-ever stroke occurred in 2 823 (2.3%) individuals in the intervention county, and 3 584 (2.7%) individuals in the control county (adjusted hazard ratio 0.96, 95% CI 0.90 to 1.03). No differences were observed for MACE, myocardial infarction or heart failure, whereas all-cause mortality (HR 0.91, 95% CI 0.87 to 0.95) and cardiovascular mortality (HR 0.91, 95% CI 0.85 to 0.98) were lower in the intervention county. CONCLUSIONS This study does not support an association between education and feedback on hypertension management to primary care physicians and the risk for stroke or cardiovascular outcomes. The observed differences for mortality outcomes should be interpreted with caution.

Age-stratified and blood-pressure-stratified effects of blood-pressure-lowering pharmacotherapy for the prevention of cardiovascular disease and death: an individual participant-level data meta-analysis. Lancet 2021; 398:1053-1064. [PMID: 34461040 PMCID: PMC8473559 DOI: 10.1016/s0140-6736(21)01921-8] [Citation(s) in RCA: 100] [Impact Index Per Article: 33.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 08/06/2021] [Accepted: 08/06/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND The effects of pharmacological blood-pressure-lowering on cardiovascular outcomes in individuals aged 70 years and older, particularly when blood pressure is not substantially increased, is uncertain. We compared the effects of blood-pressure-lowering treatment on the risk of major cardiovascular events in groups of patients stratified by age and blood pressure at baseline. METHODS We did a meta-analysis using individual participant-level data from randomised controlled trials of pharmacological blood-pressure-lowering versus placebo or other classes of blood-pressure-lowering medications, or between more versus less intensive treatment strategies, which had at least 1000 persons-years of follow-up in each treatment group. Participants with previous history of heart failure were excluded. Data were obtained from the Blood Pressure Lowering Treatment Triallists' Collaboration. We pooled the data and categorised participants into baseline age groups (<55 years, 55-64 years, 65-74 years, 75-84 years, and ≥85 years) and blood pressure categories (in 10 mm Hg increments from <120 mm Hg to ≥170 mm Hg systolic blood pressure and from <70 mm Hg to ≥110 mm Hg diastolic). We used a fixed effects one-stage approach and applied Cox proportional hazard models, stratified by trial, to analyse the data. The primary outcome was defined as either a composite of fatal or non-fatal stroke, fatal or non-fatal myocardial infarction or ischaemic heart disease, or heart failure causing death or requiring hospital admission. FINDINGS We included data from 358 707 participants from 51 randomised clinical trials. The age of participants at randomisation ranged from 21 years to 105 years (median 65 years [IQR 59-75]), with 42 960 (12·0%) participants younger than 55 years, 128 437 (35·8%) aged 55-64 years, 128 506 (35·8%) 65-74 years, 54 016 (15·1%) 75-84 years, and 4788 (1·3%) 85 years and older. The hazard ratios for the risk of major cardiovascular events per 5 mm Hg reduction in systolic blood pressure for each age group were 0·82 (95% CI 0·76-0·88) in individuals younger than 55 years, 0·91 (0·88-0·95) in those aged 55-64 years, 0·91 (0·88-0·95) in those aged 65-74 years, 0·91 (0·87-0·96) in those aged 75-84 years, and 0·99 (0·87-1·12) in those aged 85 years and older (adjusted pinteraction=0·050). Similar patterns of proportional risk reductions were observed for a 3 mm Hg reduction in diastolic blood pressure. Absolute risk reductions for major cardiovascular events varied by age and were larger in older groups (adjusted pinteraction=0·024). We did not find evidence for any clinically meaningful heterogeneity of relative treatment effects across different baseline blood pressure categories in any age group. INTERPRETATION Pharmacological blood pressure reduction is effective into old age, with no evidence that relative risk reductions for prevention of major cardiovascular events vary by systolic or diastolic blood pressure levels at randomisation, down to less than 120/70 mm Hg. Pharmacological blood pressure reduction should, therefore, be considered an important treatment option regardless of age, with the removal of age-related blood-pressure thresholds from international guidelines.

Pharmacological blood pressure lowering for primary and secondary prevention of cardiovascular disease across different levels of blood pressure: an individual participant-level data meta-analysis. Lancet 2021; 397:1625-1636. [PMID: 33933205 PMCID: PMC8102467 DOI: 10.1016/s0140-6736(21)00590-0] [Citation(s) in RCA: 365] [Impact Index Per Article: 121.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 02/28/2021] [Accepted: 03/02/2021] [Indexed: 12/15/2022]
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 mm Hg in participants without previous cardiovascular disease (n=186 988). There was substantial spread in participants' blood pressure at baseline, with 31 239 (19·8%) of participants with previous cardiovascular disease and 14 928 (8·0%) of individuals without previous cardiovascular disease having a systolic blood pressure of less than 130 mm Hg. The relative effects of blood pressure-lowering treatment were proportional to the intensity of systolic blood pressure reduction. After a median 4·15 years' follow-up (Q1-Q3 2·97-4·96), 42 324 participants (12·3%) had at least one major cardiovascular event. In participants without previous cardiovascular disease at baseline, the incidence rate for developing a major cardiovascular event per 1000 person-years was 31·9 (95% CI 31·3-32·5) in the comparator group and 25·9 (25·4-26·4) in the intervention group. In participants with previous cardiovascular disease at baseline, the corresponding rates were 39·7 (95% CI 39·0-40·5) and 36·0 (95% CI 35·3-36·7), in the comparator and intervention groups, respectively. Hazard ratios (HR) associated with a reduction of systolic blood pressure by 5 mm Hg for a major cardiovascular event were 0·91, 95% CI 0·89-0·94 for partipants without previous cardiovascular disease and 0·89, 0·86-0·92, for those with previous cardiovascular disease. In stratified analyses, there was no reliable evidence of heterogeneity of treatment effects on major cardiovascular events by baseline cardiovascular disease status or systolic blood pressure categories. INTERPRETATION In this large-scale analysis of randomised trials, a 5 mm Hg reduction of systolic blood pressure reduced the risk of major cardiovascular events by about 10%, irrespective of previous diagnoses of cardiovascular disease, and even at normal or high-normal blood pressure values. These findings suggest that a fixed degree of pharmacological blood pressure lowering is similarly effective for primary and secondary prevention of major cardiovascular disease, even at blood pressure levels currently not considered for treatment. Physicians communicating the indication for blood pressure lowering treatment to their patients should emphasise its importance on reducing cardiovascular risk rather than focusing on blood pressure reduction itself.

Impact of Comorbid Alcohol Use Disorder on Health-Related Quality of Life Among Patients With Depressive Symptoms. Front Psychiatry 2021; 12:688136. [PMID: 34690824 PMCID: PMC8531581 DOI: 10.3389/fpsyt.2021.688136] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 09/13/2021] [Indexed: 11/17/2022] Open
Abstract
Background and Aim: In psychiatric clinical practice, comorbidity of depression and alcohol use disorder (AUD) is common. Both disorders have a negative impact on health-related quality of life (HRQoL) in general population. However, research on the impact of comorbid AUD on HRQoL among clinically depressed patients is limited. The purpose of this study was to explore the impact of a psychosocial treatment intervention on HRQoL for depressive patients in specialized psychiatric care with a special focus on the impact of AUD on HRQoL. Material and Methods: Subjects were 242 patients of the Ostrobothnia Depression Study (ClinicalTrials.gov Identifier NCT02520271). Patients referred to specialized psychiatric care who scored at least 17 points on the Beck Depression Inventory at baseline and who had no psychotic disorders were included in the ODS. The treatment intervention in ODS comprised behavioral activation for all but began with motivational interviewing for those with AUD. HRQoL was assessed regularly during 24-month follow-up by the 15D instrument. In the present study, HRQoL of ODS patients with or without AUD was compared and the factors explaining 15D score analyzed with a linear mixed model. In order to specify the impact of clinical depression on HRQoL during the early phase of treatment intervention, a general population sample of the Finnish Health 2011 Survey was used as an additional reference group. Results: HRQoL improved among all ODS study sample patients regardless of comorbid AUD during the first year of follow-up. During 12-24 months of follow-up the difference between groups was seen as HRQoL continued to improve only among the non-AUD patients. A combination of male gender, anxiety disorder, and AUD was associated with the poorest HRQoL in this sample. In combined sample analyses with the reference group, clinical depression had an impact on HRQoL in short-term follow-up regardless of the treatment intervention. Conclusions: This study suggests that, in terms of improvement in HRQoL, the heterogenous group of depressive patients in specialized psychiatric care can be successfully treated with behavioral activation in combination with motivational interviewing for those with AUD.

Importance of congruence between communicating and executing implementation programmes: a qualitative study of focus group interviews. Implement Sci Commun 2020; 1:94. [PMID: 33292835 PMCID: PMC7594330 DOI: 10.1186/s43058-020-00090-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Accepted: 10/19/2020] [Indexed: 11/29/2022] Open
Abstract
Background The Ostrobothnia Depression Programme (ODP) in Finland was intended to implement two evidence-based brief psychotherapy interventions, namely motivational interview and behavioural activation, in several regional psychiatric teams. A simultaneous effectiveness study was conducted. Considerable tension was encountered between these two arms, causing resistance to change. We conducted a qualitative case study to better understand this tension and to discuss how managerial and executive practices may ensure the successful running of a hybrid design programme. Methods We conducted focus group interviews to evaluate the phases of preparation and practical execution of the ODP from the perspectives of management and the programme executives. To gather the data, we applied the revised Socratic approach for health technology assessment and focus group interviews. We analysed the data deductively according to the Normalization Process Theory. Results We identified two main critical issues: (1) The ODP programme plan ignored the team leaders’ crucial role in influencing the implementation climate and mobilizing organizational strategies. The ODP had a simplistic top-down design with minimal and delayed collaboration with its target groups in the preparation phase. (2) Incongruence occurred between what the project group had explicitly communicated about being the spearhead of the ODP and what they then actually enacted. These two issues caused tension between the implementation efforts and the effectiveness study as well as resistance to change among the staff. Conclusion Early, open collaboration with all prospective stakeholders towards a shared understanding about the programme is the first action the programme administrators should take. Agreement on goals and the means to achieve them would lower tension between the two arms of a hybrid design programme, thereby reducing resistance to change. Congruence between the goals communicated and the actual managerial and executive actions is of paramount importance in getting the programme recipients on board.

Abstract
IMPORTANCE Elevated systolic blood pressure (SBP) is the most important risk factor for premature death worldwide. However, hypertension detection and control rates continue to be suboptimal. OBJECTIVE To assess the association of education and feedback to primary care physicians with population-level SBP and hypertension control rates. DESIGN, SETTING, AND PARTICIPANTS This pooled series of 108 population-based cohort studies involving 283 079 patients used data from primary care centers in 2 counties (Västerbotten and Södermanland) in Sweden from 2001 to 2009. Participants were individuals aged 18 years or older who had their blood pressure (BP) measured and recorded in either county during the intervention period. All analyses were performed in February 2019. EXPOSURES An intervention comprising education and feedback for primary care physicians in Västerbotten County (intervention group) compared with usual care in Södermanland County (control group). MAIN OUTCOMES AND MEASURES Difference in mean SBP levels between counties and likelihood of hypertension control in the intervention county compared with the control county during 24 months of follow-up. RESULTS A total of 136 541 unique individuals (mean [SD] age at inclusion, 64.6 [16.1] years; 57.0% female; mean inclusion BP, 142/82 mm Hg) in the intervention county were compared with 146 538 individuals (mean [SD] age at inclusion, 65.7 [15.9] years; 58.3% female; mean inclusion BP, 144/80 mm Hg) in the control county. Mean SBP difference between counties during follow-up, adjusted for inclusion BP and other covariates, was 1.1 mm Hg (95% CI, 1.0-1.1 mm Hg). Hypertension control improved by 8.4 percentage points, and control was achieved in 37.8% of participants in the intervention county compared with 29.4% in the control county (adjusted odds ratio, 1.30; 95% CI, 1.29-1.31). Differences between counties increased during the intervention period and were more pronounced in participants with higher SBP at inclusion. Results were consistent across all subgroups. CONCLUSIONS AND RELEVANCE This study suggests that SBP levels and hypertension control rates in a county population may be improved by educational approaches directed at physicians and other health care workers. Similar strategies may be adopted to reinforce the implementation of clinical practice guidelines for hypertension management.

Abstract
PURPOSE Behavioural activation and motivational interviewing, both evidence-based treatments (EBTs), were implemented in secondary psychiatric care. This longitudinal evaluation of a real-world programme focused on the penetration of EBT adoption and its associations with therapist-related and perceived intervention-related variables. The implementation plan was also compared to sub-processes of Normalization Process Theory. MATERIAL AND METHODS Six participating units employed 72 therapists regularly and they comprise the target group. Due to staff turnover, a total of 84 therapists were trained stepwise. Three survey points (q1, q2, q3) were set for a four-year cycle beginning a year after the initial training and completed 4-5 months after closing patient recruitment. The implementation plan included two workshop days, one for each EBT, and subsequent case consultation groups and other more general strategies. RESULTS Fifty-seven (68%) of programme-trained therapists responded to one or more of three questionnaires. The self-reported penetration covers about a third of the target group a few months after the completion of the programme. Therapists' favourable perceptions of the EBTs regarding relative advantage, compatibility and complexity were associated with their sustained adoption. Therapists' background factors (e.g. work experience) and positive adoption intention at q1 did not predict the actual adoption of the EBTs at q3. No specific sustainment strategies were included in the implementation plan. CONCLUSION Brief but multi-faceted training with subsequent case consultations promoted the adoption of EBTs in a real-world setting. Adding specific sustainment strategies to the implementation plan is proposed to ensure the long-term survival of the implementation outcomes.

Abstract
BACKGROUND More systematic use of evidence-based brief therapies is needed in the treatment of depression within psychiatric care. The aim of this study was to explore the impact of behavioral activation therapy (BA) for patients with depressive symptoms in a routine clinical setting of secondary psychiatric care. METHODS The BA-treated intervention group (n = 242) comprised patients with depressive symptoms (Beck Depression Inventory (BDI) score ≥ 17 at baseline). The control group (n = 205) patients received treatment as usual in the same catchment area. The groups were matched at baseline using BDI and Alcohol Use Disorders Identification Test scores and inpatient/outpatient status. The groups were compared at 6-, 12- and 24-month follow-up points on functional outcome (Global Assessment of Functioning scale), service use, dropout and deaths. The Montgomery-Åsberg Depression Rating Scale was used to assess depressive symptoms in the intervention group. RESULTS The estimated difference in GAF score between intervention and control group patients was significant at 12- and 24-months follow-up points in favor of intervention group (GAF score difference 4.85 points, p = 0.006 and 5.71 points, p = 0.005, respectively; estimate for patient group 2.26, p = 0.036). The rates of dropout, mortality and service use were similar between the groups. Among the intervention group patients, the estimated improvement in MADRS score compared to baseline was statistically significant throughout the follow-up (p < 0.001 at all follow-up points). CONCLUSIONS The systematic use of BA among secondary psychiatric care depressive patients provides encouraging results despite the patients had various comorbid non-psychotic disorders.

Abstract
This implementation study was part of the Ostrobothnia Depression Study, in Finland, which covered implementation of motivational interviewing (MI) and behavioral activation (BA) within regional public psychiatric secondary care. It aimed to evaluate the mid-term progress of implementation and related factors. Altogether, 80 therapists had been educated through the implementation program by the point of the mid-term evaluation. Eligible information for evaluation was gathered using two questionnaires (q1, q2) with a one-year interval. A total of 45 of the 80 therapists completed q1, 30 completed q2, and 24 completed both questionnaires. Professional education was the only background factor associated with adopting the interventions (q1: p=0.059, q2: p=0.023), with higher education indicating greater activity. On the basis of trends such as changes in overall usefulness score from q1 to q2, the most involved therapists were slightly more likely to adopt MI/BA. Our experience so far suggests that encouraging staff to begin using new interventions during education is very important. The Consolidated Framework for Implementation Research was found to be a useful tool for constructing the evaluation.

Abstract
AIMS Although hypertensive patients with low baseline HDL cholesterol levels have a higher incidence of diabetes mellitus, whether changing levels of HDL over time are more strongly related to the risk of new diabetes in hypertensive patients has not been examined. METHODS Incident diabetes mellitus was examined in relation to baseline and in-treatment HDL levels in 7485 hypertensive patients with no history of diabetes randomly assigned to losartan- or atenolol-based treatment. RESULTS During 4.7 ± 1.2 years follow-up, 520 patients (6.9%) developed new diabetes. In univariate Cox analyses, compared with the highest quartile of HDL levels (> 1.78 mmol/l), baseline and in-treatment HDL in the lowest quartile (< 1.21 mmol/l) identified patients with > 5-fold and > 9 fold higher risks of new diabetes, respectively; patients with baseline or in-treatment HDL in the 2nd and 3rd quartiles had intermediate risk of diabetes. In multivariable Cox analyses, adjusting for randomized treatment, age, sex, race, prior anti-hypertensive therapy, baseline uric acid, serum creatinine and glucose entered as standard covariates, and in-treatment non-HDL cholesterol, Cornell product left ventricular hypertrophy, diastolic and systolic pressure, BMI, hydrochlorothiazide and statin use as time-varying covariates, the lowest quartile of in-treatment HDL remained associated with a nearly 9-fold increased risk of new diabetes (hazard ratio 8.7, 95% CI 5.0-15.2), whereas the risk of new diabetes was significantly attenuated for baseline HDL < 1.21 mmol/l (hazard ratio 3.9, 95% CI 2.8-5.4). CONCLUSIONS Lower in-treatment HDL is more strongly associated with increased risk of new diabetes than baseline HDL level.

Abstract
OBJECTIVES To determine the population distribution of cardiovascular risk in eight low- and middle-income countries and compare the cost of drug treatment based on cardiovascular risk (cardiovascular risk thresholds ≥ 30%/≥ 40%) with single risk factor cutoff levels. STUDY DESIGN AND SETTING Using World Health Organization (WHO) and the International Society of Hypertension risk prediction charts, cardiovascular risk was categorized in a cross-sectional study of 8,625 randomly selected people aged 40-80 years (mean age, 54.6 years) from defined geographic regions of Nigeria, Iran, China, Pakistan, Georgia, Nepal, Cuba, and Sri Lanka. Cost estimates for drug therapy were calculated for three countries. RESULTS A large fraction (90.0-98.9%) of the study population has a 10-year cardiovascular risk <20%. Only 0.2-4.8% are in the high-risk categories (≥ 30%). Adopting a total risk approach and WHO guidelines recommendations would restrict unnecessary drug treatment and reduce the drug costs significantly. CONCLUSION Adopting a total cardiovascular risk approach instead of a single risk factor approach reduces health care expenditure by reducing drug costs. Therefore, limited resources can be more efficiently used to target high-risk people who will benefit the most. This strategy needs to be complemented with population-wide measures to shift the cardiovascular risk distribution of the whole population.

Abstract
OBJECTIVE Construction of prognostically relevant endpoints for clinical trials in hypertension has increasingly included coronary revascularization with myocardial infarction (MI) as manifestations of coronary artery disease. However, whether coronary revascularization and MI predict other cardiovascular events similarly is unknown. METHODS We examined risks of cardiovascular death, all-cause death, and stroke following MI or coronary revascularization in hypertensive patients with left ventricular hypertrophy (LVH) enrolled in the Losartan Intervention For Endpoint reduction in hypertension study (LIFE). We studied 9113 patients after excluding those who died within 7 days after MI or underwent coronary revascularization within 24 h after MI. RESULTS In multivariate Cox regression adjusting for participating countries, time-varying systolic blood pressure, and Framingham risk score, hazard ratios for cardiovascular death, all-cause death, and stroke were, respectively, 4.5 (P<0.0001), 2.9 (P<0.0001), and 1.9 (P=0.003) in 321 patients with MI as first event. In similar models, coronary revascularization as first event (n=202) was not associated with increased risks of cardiovascular death, all-cause death, and stroke (P=0.06-0.86). CONCLUSION During follow-up of hypertensive patients with LVH, occurrence of MI but not coronary revascularization as first cardiovascular event significantly increased risk of subsequent cardiovascular death, all-cause death, and stroke. In view of differences in prognostic implications, when the goal is to have a prognostically relevant composite endpoint for trials in hypertensive patients, caution should be used in combining coronary revascularization with MI.

Abstract
OBJECTIVE We assessed readily available patient characteristics, including albuminuria (not included in traditional cardiovascular risk scores), as predictors of cardiovascular events in hypertension with left ventricular hypertrophy (LVH) and developed risk algorithms/scores for outcomes. METHODS The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study compared effects of losartan-based versus atenolol-based therapy on cardiovascular events in 9193 patients with hypertension and LVH. Univariate and multivariate analyses identified baseline variables with significant impact on development of the primary composite endpoint (cardiovascular death, stroke and myocardial infarction) and its components. Multivariate analysis used a Cox regression model with stepwise selection process. Risk scores were developed from coefficients of risk factors from the multivariate analysis, validated internally using naïve and jack-knife procedures, checked for discrimination and calibration, and compared with Framingham coronary heart disease and other risk scores. RESULTS LIFE risk scores showed increasing endpoint rates with increasing quintile (first to fifth quintile, composite endpoint 2.8-26.7%, cardiovascular death 0.5-14.4%, stroke 1.2-11.3%, myocardial infarction 1.4-8.1%) and were confirmed with a jack-knife approach that adjusts for potentially optimistic bias. The Framingham coronary heart disease and other risk scores overestimated risk in lower risk patients and underestimated risk in higher risk patients, except for myocardial infarction. CONCLUSION A number of patient characteristics predicted cardiovascular events in patients with hypertension and LVH. Risk scores developed from these patient characteristics, including albuminuria, strongly predicted outcomes and may improve risk assessment of patients with hypertension and LVH and planning of clinical trials.

Abstract
BACKGROUND Hypertension cannot always be adequately controlled with available drugs. We investigated the blood-pressure-lowering effects of the new vasodilatory, selective endothelin type A antagonist, darusentan, in patients with treatment-resistant hypertension. METHODS This randomised, double-blind study was undertaken in 117 sites in North and South America, Europe, New Zealand, and Australia. 379 patients with systolic blood pressure of 140 mm Hg or more (>/=130 mm Hg if patient had diabetes or chronic kidney disease) who were receiving at least three blood-pressure-lowering drugs, including a diuretic, at full or maximum tolerated doses were randomly assigned to 14 weeks' treatment with placebo (n=132) or darusentan 50 mg (n=81), 100 mg (n=81), or 300 mg (n=85) taken once daily. Randomisation was made centrally via an automated telephone system, and patients and all investigators were masked to treatment assignments. The primary endpoints were changes in sitting systolic and diastolic blood pressures. Analysis was by intention to treat. The study is registered with ClinicalTrials.gov, number NCT00330369. FINDINGS All randomly assigned participants were analysed. The mean reductions in clinic systolic and diastolic blood pressures were 9/5 mm Hg (SD 14/8) with placebo, 17/10 mm Hg (15/9) with darusentan 50 mg, 18/10 mm Hg (16/9) with darusentan 100 mg, and 18/11 mm Hg (18/10) with darusentan 300 mg (p<0.0001 for all effects). The main adverse effects were related to fluid accumulation. Oedema or fluid retention occurred in 67 (27%) patients given darusentan compared with 19 (14%) given placebo. One patient in the placebo group died (sudden cardiac death), and five patients in the three darusentan dose groups combined had cardiac-related serious adverse events. INTERPRETATION Darusentan provides additional reduction in blood pressure in patients who have not attained their treatment goals with three or more antihypertensive drugs. As with other vasodilatory drugs, fluid management with effective diuretic therapy might be needed. FUNDING Gilead Sciences.

Abstract
A blood pressure screening was carried out in women aged 40-64 years in a geographically defined area in southern Sweden; the attendance was 72%. Middle-aged women classified as normotensives by standard criteria were found to differ from hypertensives also when blood pressure was recorded with non-invasive ambulatory technique; this was so when calculated for day, night, and 24 hours. The frequency of ambulatory blood pressure values > or = 140/90 mmHg was also significantly lower in normotensives than in hypertensives. The established way of diagnosing hypertension and normotension thus correlated well with the results of ambulatory monitoring in women. Furthermore, women had their highest blood pressure in the late afternoon and not in the mornings, as previously shown in men. This was so in all three groups of women (normotensives, borderline hypertensives, and hypertensives). This difference leaves room for speculation about different types of stress load during the day in men and women.

Abstract
The 1999 hypertension management guidelines issued by the World Health Organization and the International Society of Hypertension emphasize the importance of blood pressure reduction in the prevention of cardiovascular events. Furthermore, they conclude that the benefits of treatment are due to blood pressure lowering per se, rather than to any specific antihypertensive therapy. The results of the second Swedish Trial in Old Patients with Hypertension (STOP-Hypertension-2) are consistent with these recommendations, since in this trial angiotensin converting enzyme (ACE) inhibitors and calcium antagonists reduced blood pressure to the same extent as conventional therapy with beta-blockers and diuretics in elderly hypertensive patients, and the three treatments produced similar reductions in the risk of cardiovascular events. Furthermore, a first subgroup analysis of cardiovascular mortality showed that the three treatments seemed equally effective in diabetic patients. The STOP-Hypertension-2 data, therefore, are fully consistent with the 1999 hypertension management guidelines, and underline the advantages offered by both older and newer antihypertensive therapies.

Abstract
OBJECTIVE To compare costs for management of hypertension in elderly hypertensives randomized to starting treatment with conventional (beta-blockers/diuretics) therapy or a therapy initiated with a calcium antagonist or an angiotensin-converting enzyme (ACE) inhibitor. DESIGN Health economic substudy in the Swedish Trial in Old Patients with Hypertension-2 (STOP Hypertension-2). SETTING Outpatient clinics in Sweden. In this health economics substudy, 16/312 participating STOP-2 trial centers were selected. SUBJECTS Elderly (70--84 years) patients (n=303) with a systolic and/or diastolic hypertension (or=180 and/or 105 mmHg). METHODS Costs for patient management were analyzed and categorized in costs for routine care (protocol-driven costs, PDC), costs for extra visits or care (non-protocol-driven costs, NPDC), and direct drug costs (drug treatment costs, DTC). All calculations are related to costs during the first year of treatment after inclusion in STOP Hypertension-2. RESULTS Out of the scheduled visits, a total of 99% were actually performed by the patients. There were no differences in the number of visits between the three treatment groups (diuretics/beta-blockers, calcium antagonists or ACE inhibitors). PDC did thus not differ between the three treatment groups. NPDC were similar in the conventional and calcium antagonist groups and lower than for the ACE inhibitor group. DTC were lower in the conventional treatment group compared with the other two groups. CONCLUSION. In elderly hypertensives in STOP Hypertension-2, total costs for management of hypertension were lower in patients assigned to diuretics, beta-blockers or calcium antagonists compared with ACE inhibitors during the first year of treatment. These results may be relevant to management of elderly hypertensive patients, especially in those patients without compelling indications or contraindications to starting treatment with either of these three main drug alternatives. Notably, with a specific drug regimen there are sizable NPDC such as extra visits and controls associated with symptoms or side-effects of a specific therapy, which significantly add to the total costs of treatment. Such costs, beyond the actual costs for the drugs, are important to realize and evaluate in order to provide the true costs for treatment of hypertensive patients.

Abstract
BACKGROUND Onset of atrial fibrillation (AF) has been linked to changes in autonomic tone, with increasing heart rate (HR) immediately before AF onset in some patients suggesting a possible role of acute increases in sympathetic activity in AF onset. Although losartan therapy and decreasing ECG left ventricular hypertrophy are associated with decreased AF incidence, the relationship of HR changes over time to development of AF has not been examined. METHODS AND RESULTS HR was evaluated in 8828 hypertensive patients without AF by history or on baseline ECG in the Losartan Intervention for End Point Reduction in Hypertension (LIFE) study. Patients were treated with losartan- or atenolol-based regimens and followed with serial ECGs annually which were used to determine HR and ECG left ventricular hypertrophy by Cornell product and Sokolow-Lyon voltage criteria. During mean follow-up of 4.7+/-1.1 years, new-onset AF occurred in 701 patients (7.9%). Patients with new AF had smaller decreases in HR to last in-treatment ECG or last ECG before AF (-2.7+/-13.5 versus -5.2+/-12.5 bpm), whether on losartan- (-0.4+/-13.5 versus -2.2+/-11.7 bpm) or atenolol-based treatment (-5.3+/-12.8 versus -8.3+/-12.6 bpm, all P<0.001). In univariate Cox analyses, higher HR on in-treatment ECGs was associated with an increased risk of new-onset AF, with a 15% greater risk of AF for every 10 bpm higher HR (95% CI 8% to 22%). In alternative analyses, persistence or development of a HR> or =84 (upper quintile of baseline HR) was associated with a 46% greater risk of developing AF (95% CI 19% to 80%). After adjusting for treatment with losartan versus atenolol, baseline risk factors for AF, baseline and in-treatment systolic and diastolic pressure and the known predictive value of baseline and in-treatment ECG left ventricular hypertrophy for new AF, higher in-treatment HR remained strongly associated with new AF with a 19% higher risk for every 10 bpm higher HR (95% CI 10% to 28%) or a 61% increased rate of AF in patients with persistence or development of a HR> or =84 (95% CI 27% to 104%, all P<0.001). CONCLUSIONS Higher in-treatment HR on serial ECGs is associated with an increased likelihood of new-onset AF, independent of treatment modality, blood pressure lowering, and regression of ECG left ventricular hypertrophy in patients with essential hypertension.

Abstract
In type 2 diabetes the degree of albuminuria is strongly related to progression of diabetic renal disease, as well as to the risk for cardiovascular complications. If normoalbuminuria is maintained, the risk of diabetic nephropathy is very low. In individuals with microalbuminuria, the rate of decline in glomerular filtration rate is closely related to the degree of albuminuria, and regression to normoalbuminuria slows down the rate of decline in renal function. Data from the LIFE-diabetes subgroup showed that levels of albuminuria well below what is usually defined as microalbuminuria, strongly predicted risk for cardiovascular complications. This indicates that when albuminuria is used as a risk predictor for cardiovascular events, so called normal values should be redefined. Traditional values for normo-micro-macroalbuminuria are primarily defined as predictors for the risk of development of diabetic nephropathy. In the LIFE-diabetes subgroup we found that reduction in albuminuria was more pronounced in losartan-based as compared with atenolol-based treatment. The benefit in favor of losartan was partly related to its major influence on albuminuria. Individuals with the highest baseline values of albuminuria had the greatest benefit in terms of reduction in cardiovascular morbidity and mortality on losartan as compared with atenolol. The level of albuminuria during treatment was closely related to the risk for cardiovascular events. We conclude that tiny amounts of albuminuria, well below traditional levels for microalbuminuria, predict cardiovascular morbidity and mortality. Reduction in albuminuria during treatment translates to reduction in cardiovascular events. Monitoring of albuminuria should be an integrated part of management of hypertension in diabetic as well as nondiabetic patients.

Abstract
Treatment of hypertensive patients with electrocardiographic left ventricular hypertrophy with losartan-based therapy is associated with lower incidence of diabetes mellitus and greater regression of hypertrophy than atenolol-based therapy. However, whether in-treatment resolution or continued absence of electrocardiographic hypertrophy is independently associated with decreased incidence of diabetes is unclear. Electrocardiographic hypertrophy was evaluated over time in 7998 hypertensive patients without diabetes at baseline in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study who were treated with losartan- or atenolol-based regimens and followed with serial electrocardiograms and blood pressure determinations. Electrocardiographic hypertrophy was defined using gender-adjusted Cornell voltage-duration product criteria >2440 mm·ms. During mean follow-up of 4.6±1.2 years, diabetes developed in 562 patients (7.0%). In a Cox model adjusting for treatment assignment, in-treatment resolution or continued absence of Cornell product hypertrophy was associated with a 38% lower risk of new diabetes (HR 0.62, 95% CI 0.50 to 0.78). After adjusting for the association of new diabetes with prior antihypertensive treatment, baseline glucose, and Framingham risk score, baseline and in-treatment systolic and diastolic pressure, HDL, uric acid, and body mass index, and the decreased incidence associated with losartan-based therapy, in-treatment continued absence, or resolution of Cornell product hypertrophy remained associated with a 26% lower risk of new diabetes (HR 0.74, 95% CI 0.58 to 0.93). Thus, compared with presence of hypertrophy by Cornell product criteria during antihypertensive treatment, resolution or continued absence of Cornell product hypertrophy is associated with a lower incidence of diabetes, even after adjusting for the impact of treatment with losartan and other risk factors for diabetes.

Abstract
Cardiovascular disease (CVD) is the leading cause of the growing global disease burden due to non-communicable diseases. For successful prevention and control of CVD, strategies that focus on individuals need to complement population-wide strategies. Strategies that focus on individuals are cost effective only when targeted at high-risk groups. Risk prediction tools that easily and accurately predict an individual's absolute risk of CVD are key to targeting limited resources at high-risk individuals who are likely to benefit the most. Health systems in low-income countries do not have the basic infrastructure facilities to support resource-intensive risk prediction tools, particularly in primary healthcare. The WHO/ISH charts presented here, enable the prediction of future risk of heart attacks and strokes in people living in low and middle income countries, for the first time. Furthermore, since the charts use simple variables they can be applied even in low resource settings. Thus the WHO/ISH risk predication charts and the accompanying guideline will improve the effectiveness of cardiovascular risk management even in settings which do not have sophisticated technology.

Abstract
Background—
Sudden cardiac death (SCD) occurs more often in patients with ECG left ventricular (LV) hypertrophy. However, whether LV hypertrophy regression is associated with a reduced risk of SCD remains unclear.
Methods and Results—
The Losartan Intervention for End Point Reduction in Hypertension (LIFE) study included 9193 patients 55 to 80 years of age with essential hypertension and ECG LV hypertrophy by gender-adjusted Cornell product (CP) (RaVL+SV
3
[+6 mm in women]) · QRS duration>2440 mm · ms) and/or Sokolow-Lyon voltage (SLV) (SV

+RV
5/6
>38 mm). During follow-up (mean, 4.8 years), 190 patients (2%) experienced SCD. In time-dependent Cox analyses, absence of in-treatment LV hypertrophy was associated with a decreased risk of SCD: every 1-SD-lower in-treatment CP (1050 mm · ms) was associated with a 28% lower risk of SCD (hazard ratio [HR], 0.72; 95% CI, 0.66 to 0.79) and 1-SD-lower SLV (10.5 mm) with a 26% lower risk (HR, 0.74; 95% CI, 0.65 to 0.84). After adjustment for time-varying systolic and diastolic blood pressures, treatment allocation, age, gender, baseline Framingham risk score, ECG strain, heart rate, urine albumin/creatinine ratio, smoking, diabetes, congestive heart failure, coronary heart disease, atrial fibrillation, and occurrence of myocardial infarction, atrial fibrillation, heart failure, and noncardiovascular death, both in-treatment CP and SLV remained predictive of SCD: each 1-SD-lower CP was associated with a 19% lower risk of SCD (HR, 0.81; 95% CI, 0.73 to 0.90) and 1-SD-lower SLV with an 18% lower risk (HR, 0.82; 95% CI, 0.70 to 0.98). Absence of in-treatment LV hypertrophy by both SLV and CP was associated with a 30% lower risk of SCD (HR, 0.70; 95% CI, 0.54 to 0.92).
Conclusions—
Absence of in-treatment ECG LV hypertrophy is associated with reduced risk of SCD independently of treatment modality, blood pressure reduction, prevalent coronary heart disease, and other cardiovascular risk factors in hypertensive patients with LV hypertrophy.

Abstract
OBJECTIVE To investigate whether a threshold exists for cardiovascular risk in type 2 diabetic patients with hypertension, the association between renal function and cardiovascular risk was examined across the entire physiological range of serum creatinine. DESIGN AND METHODS The RENAAL and LIFE studies enrolled 1513 and 1195 patients with type 2 diabetes and hypertension, respectively. The relationship between baseline serum creatinine and the risk for a composite outcome of myocardial infarction, stroke or cardiovascular death was examined using Cox regression models. To adjust for heterogeneity between studies and treatment groups, these factors were included as strata when applicable. The analyses were conducted with adjustment for age, gender, smoking, alcohol use, blood pressure, heart rate, total and high-density lipoprotein (HDL) cholesterol, hemoglobin, albuminuria and prior cardiovascular disease. RESULTS The hazard ratios across the baseline serum creatinine categories < 0.9 mg/dl, 0.9-1.2 mg/dl, 1.2-1.6 mg/dl, 1.6-2.8 mg/dl and >or= 2.8 mg/dl were 0.51 (95% confidence interval 0.34, 0.74), 0.74 (0.55, 1.00), 1.00 (reference), 1.24 (0.96, 1.59) and 1.67 (1.17, 2.91), respectively. Baseline serum creatinine (per mg/dl) strongly predicted the composite cardiovascular endpoint in LIFE [2.82(1.74,4.56), P < 0.001], RENAAL [1.41(1.12,1.79), P < 0.001], as well as the combined studies [1.51(1.21,1.87), P < 0.001]. CONCLUSION A progressively higher risk for the composite cardiovascular endpoint was observed with incremental baseline serum creatinine in type 2 diabetic patients with hypertension, even within the normal range. Thus, there appears to be no serum creatinine threshold level for an increased cardiovascular risk. Baseline serum creatinine was a major independent risk factor for cardiovascular disease (www.ClinicalTrials.gov number NCT00308347).

Abstract
OBJECTIVE To compare blood pressure response and antihypertensive medication use visit-by-visit from baseline in patients receiving losartan-based or atenolol-based therapy in the LIFE study. RESEARCH DESIGN LIFE was a randomized, double-blind trial comparing losartan-based and atenolol-based treatment regimens on the primary composite endpoint of death, myocardial infarction (MI), or stroke in 9193 patients aged 55-80 years with hypertension and left ventricular hypertrophy. Systolic and diastolic, pulse, and mean arterial pressures, blood pressure responder rates, distribution of open-label antihypertensive agents utilized, and the proportion of patients on randomized treatment were determined for each group at each clinic visit over a follow-up period of at least 4 years. RESULTS Overall blood pressure reductions were comparable in the losartan-based and atenolol-based treatment groups. The mean reductions in sitting trough systolic and diastolic blood pressures from baseline to the end of follow-up (or last visit before a primary endpoint event) were 30.2/16.6 mmHg in the losartan group and 29.1/16.8 mmHg in the atenolol group. The time-averaged difference in overall mean arterial pressure was similar between groups. The proportion of patients on individual dose combinations varied visit by visit but was generally comparable between groups. During the entire study, 56% (2579/4605) of losartan-treated patients received at least one dose of the combination of losartan 100 mg plus hydrochlorothiazide 12.5 mg and 51% of atenolol-treated patients received 100 mg of atenolol plus hydrochlorothiazide 12.5 mg at some time during the study. CONCLUSIONS Differences in blood pressure or distribution of add-on medications between treatment groups were not evident in the LIFE trial and, thus, cannot account for the observed outcome difference in the primary endpoint of risk reduction of the composite of cardiovascular death, stroke and MI favoring losartan.

Abstract
CONTEXT Atrial fibrillation (AF) is associated with increased risk of mortality and cardiovascular events, particularly stroke, making prevention of new-onset AF a clinical priority. Although the presence and severity of electrocardiographic left ventricular hypertrophy (LVH) appear to predict development of AF, whether regression of electrocardiographic LVH is associated with a decreased incidence of AF is unclear. OBJECTIVE To test the hypothesis that in-treatment regression or continued absence of electrocardiographic LVH during antihypertensive therapy is associated with a decreased incidence of AF, independent of blood pressure and treatment modality. DESIGN, SETTING, AND PARTICIPANTS Double-blind, randomized, parallel-group study conducted in 1995-2001 among 8831 men and women with hypertension, aged 55-80 years (median, 67 years), with electrocardiographic LVH by Cornell voltage-duration product or Sokolow-Lyon voltage, with no history of AF, without AF on the baseline electrocardiogram, and enrolled in the Losartan Intervention for Endpoint Reduction in Hypertension Study. INTERVENTIONS Losartan- or atenolol-based treatment regimens, with follow-up assessments at 6 months and then yearly until death or study end. MAIN OUTCOME MEASURE New-onset AF in relation to electrocardiographic LVH determined at baseline and subsequently. Electrocardiographic LVH was measured using sex-adjusted Cornell product criteria ({R(aVL) + S(V3) [+ 6 mm in women]} x QRS duration). RESULTS After a mean (SD) follow-up of 4.7 (1.1) years, new-onset AF occurred in 290 patients with in-treatment regression or continued absence of Cornell product LVH for a rate of 14.9 per 1000 patient-years and in 411 patients with in-treatment persistence or development of LVH by Cornell product criteria for a rate of 19.0 per 1000 patient-years. In time-dependent Cox analyses adjusted for treatment effects, baseline differences in risk factors for AF, baseline and in-treatment blood pressure, and baseline severity of electrocardiographic LVH, lower in-treatment Cornell product LVH treated as a time-varying covariate was associated with a 12.4% lower rate of new-onset AF (adjusted hazard ratio [HR], 0.88; 95% CI, 0.80-0.97; P = .007) for every 1050 mm x msec (per 1-SD) lower Cornell product, with persistence of the benefit of losartan vs atenolol therapy on developing AF (HR, 0.83; 95% CI, 0.71-0.97; P = .01). CONCLUSIONS Lower Cornell product electrocardiographic LVH during antihypertensive therapy is associated with a lower likelihood of new-onset AF, independent of blood pressure lowering and treatment modality in essential hypertension. These findings suggest that antihypertensive therapy targeted at regression or prevention of electrocardiographic LVH may reduce the incidence of new-onset AF.

Abstract
OBJECTIVE To present a cost-effectiveness analysis of the Antihypertensive Treatment and Lipid Profile in a North of Sweden Efficacy Evaluation study (ALPINE). DESIGN In newly diagnosed hypertensive individuals as yet untreated with drugs, the ALPINE study compared the 1-year metabolic effects of inexpensive treatment with a diuretic (hydrochlorothiazide), alone or in combination (84%) with a beta-adrenoceptor blocker (atenolol), with that of newer but also more expensive antihypertensive treatment with an angiotensin II receptor blocker (candesartan), alone or in combination (71%) with a calcium antagonist (felodipine). No crossover of medication was allowed. The cost-effectiveness analysis included costs for antihypertensive treatment during follow-up, and lifetime costs for care of diabetes mellitus diagnosed during follow-up. Cost per patient was calculated using Swedish prices and costs, translated into US dollars (US$), at 2004 prices. RESULTS Diabetes mellitus was diagnosed in nine patients during the 1-year follow-up period of the study, eight in the hydrochlorothiazide group (4.1%) and one (0.5%) in the candesartan/felodipine group (P < 0.05). The cost of antihypertensive treatment per patient was US$92 in the hydrochlorothiazide/atenolol group and US$422 in the candesartan/felodipine group. Lifetime cost for care of diabetes mellitus per patient in the two groups was US$1013 and US$127, respectively. Total cost per patient was US$556 less in the candesartan/felodipine group. In sensitivity analyses, the outcome for the candesartan/felodipine group ranged from cost savings to an incremental cost of US$30 000 per case of diabetes mellitus prevented. In all analyses but one, the additional cost for antihypertensive treatment in the candesartan/felodipine group could be balanced by the reduced lifetime cost for care of diabetes mellitus. CONCLUSIONS The results suggest that an antihypertensive treatment strategy with candesartan and felodipine may have a favourable health economic impact in the longer term.

Abstract
BACKGROUND In the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study, reduced urine albumin/creatinine ratio (UACR) as well as regression of left ventricular hypertrophy have been associated with lower incidence of cardiovascular events. We wanted to investigate whether these prognostic improvements were independent. METHODS In 6679 hypertensive patients included in the LIFE study, we measured UACR, left ventricular hypertrophy by electrocardiography, serum cholesterol, plasma glucose and blood pressure after 2 weeks of placebo treatment and again after 1 year of anti-hypertensive treatment with either an atenolol- or a losartan-based regimen. During this first year of treatment, 77 patients encountered a non-fatal stroke or myocardial infarction and were excluded to avoid bias. During the next 3-4 years, 610 composite endpoints [cardiovascular death (n = 228), fatal or non-fatal myocardial infarction or stroke] were recorded. RESULTS In Cox regression analyses, the composite endpoint was after adjustment for treatment allocation predicted by baseline logUACR [hazard ratio (HR) = 1.16 per 10-fold increase, P < 0.05], 1-year logUACR (HR = 1.29 per 10-fold increase), baseline Sokolow-Lyon voltage (HR = 1.01 per mm, both P < 0.001) and 1-year Cornell product (HR = 1.01 per 100 mm x ms, P < 0.01). Cardiovascular death was predicted by 1-year logUACR (HR = 1.59, P < 0.001), baseline Sokolow-Lyon voltage (HR = 1.01, P = 0.06) and 1-year Cornell product (HR = 1.02, P < 0.001). Both were predicted independent of age, Framingham risk score, current smoking, history of cardiovascular disease and diabetes. Gender, serum cholesterol, plasma glucose and blood pressure did not enter the models. CONCLUSIONS Baseline UACR and Sokolow-Lyon voltage, as well as in-treatment UACR and Cornell product, added to the risk prediction independent of traditional risk factors, indicating that albuminuria and left ventricular hypertrophy reflect different aspects of cardiovascular damage and are modifiable cardiovascular risk factors.

Abstract
Agents that counteract the negative impact of the renin-angiotensin-aldosterone system (RAAS) are effective antihypertensives and reduce the risk of developing Type 2 diabetes. Contrary to common perception, angiotensin-converting enzyme inhibitors do not share the apparent benefit of angiotensin II receptor blockers (ARBs) in reducing risk of cardiovascular-disease outcomes, particularly stroke, in randomised clinical trials. RAAS agents, especially ARBs, are well tolerated. Use of ARBs alone or in combination with other classes of antihypertensive agents to lower blood pressure and/or medications to control other conditions (e.g., insulin sensitivity) reduces risk of cardiovascular disease outcomes and Type 2 diabetes with excellent tolerability. Selected issues related to use of RAAS agents as antihypertensive therapies (e.g., Type 2 diabetes, global risk management, multiple drug therapy and coronary heart disease) are addressed.

Abstract
Background—
Diabetes mellitus is associated with increased cardiovascular (CV) morbidity and mortality and with greater ECG left ventricular hypertrophy (LVH); however, it is unclear whether diabetes attenuates regression of hypertensive LVH and whether regression of ECG LVH has similar prognostic value in diabetic and nondiabetic hypertensive individuals.
Methods and Results—
A total of 9193 hypertensive patients (1195 with diabetes) in the Losartan Intervention For Endpoint (LIFE) Reduction in Hypertension Study were treated with losartan- or atenolol-based regimens and followed up with serial ECG and blood pressure determinations at baseline and 6 months and then yearly until death or study end. ECG LVH was defined with gender-adjusted Cornell voltage-duration product (CP) criteria >2440 mm · ms. After a mean follow-up of 4.8±0.9 years, patients with diabetes had less regression of CP LVH (−138±866 versus −204±854 mm · ms,
P
<0.001), remained more likely to have LVH by CP (56.0% versus 48.1%,
P
<0.001), and had higher rates of CV death, myocardial infarction, stroke, and all-cause mortality and of the LIFE composite end point of CV death, myocardial infarction, or stroke. In multivariable Cox proportional hazards models, in-treatment regression or absence of ECG LVH by CP was associated with between 17% and 35% reductions in event rates in patients without diabetes but did not significantly predict outcome in patients with diabetes.
Conclusions—
Hypertensive patients with diabetes have less regression of CP LVH in response to antihypertensive therapy than patients without diabetes, and regression of ECG LVH is less useful as a surrogate marker of outcomes in hypertensive patients with diabetes. These findings may in part explain the higher CV morbidity and mortality in hypertensive patients with diabetes, and the absence of a demonstrable improvement in prognosis in diabetic patients in response to regression of ECG LVH suggests a more complex interrelation between underlying LV structural and functional abnormalities and outcome in these patients.

Abstract
OBJECTIVE Our current aims were to investigate whether 1) baseline urinary albumin-to-creatinine ratio (UACR) predicted cardiovascular outcomes, 2) changes in UACR differed between treatments, 3) benefits of losartan were related to its influence on UACR, and 4) reduction in albuminuria reduced cardiovascular events. RESEARCH DESIGN AND METHODS In 1,063 patients with diabetes, hypertension, and left ventricular hypertrophy, UACR was measured for a mean of 4.7 years. The primary composite end point included cardiovascular death, myocardial infarction, and stroke. Cox models were run including and excluding baseline and time-varying UACR. RESULTS Increasing baseline albuminuria related to increased risk for cardiovascular events. Reductions in UACR at years 1 and 2 were approximately 33% for losartan vs. 15% for atenolol (P < 0.001). Benefits of losartan seem to be most prominent in patients with the highest level of baseline UACR, although treatment by albuminuria interaction was only significant for total mortality. Approximately one-fifth of the superiority of losartan was explained by the greater reduction of albuminuria. Risk of the primary end point was related to the in-treatment UACR. CONCLUSIONS Lowering of albuminuria in patients with hypertension and diabetes appears to be beneficial and should be the subject of additional study in future clinical trials.

Abstract
We sought to study the risk factors for heart failure (HF) and the relation between antihypertensive treatment with losartan and the first hospitalization for HF in patients with diabetes mellitus in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) and Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) studies. We evaluated 1,195 patients with hypertension, left ventricular hypertrophy, and diabetes from the LIFE study and 1,513 patients with type 2 diabetes and nephropathy from the RENAAL study. The comparative treatments were atenolol in the LIFE study and placebo in the RENAAL study. Patients with a history of HF were excluded from this analysis. Losartan significantly reduced the incidence of first hospitalizations for HF versus placebo in the RENAAL study (hazard ratio 0.74, p=0.037) and versus atenolol in the LIFE study (hazard ratio 0.57, p=0.019). Patients enrolled in the RENAAL study were at a higher risk of developing HF (hazard ratio for RENAAL vs LIFE diabetics 3.0, p<0.0001). The significant, independent baseline risk factors for the development of HF in the RENAAL study were urinary albumin/creatinine ratio, age, peripheral vascular disease, the Cornell product, body mass index, and previous angina; in the LIFE study they were the Cornell product, previous myocardial infarction, peripheral vascular disease, baseline atrial fibrillation, alcohol use (inverse relation), and urinary albumin/creatinine ratio. The beneficial effect of losartan on the reduction of risk for hospitalization for new HF was demonstrated in patients who were at high renal and/or high cardiovascular risk.
