    • OBJECTIVES: Added-risk hypertensive patients with co-morbidities such as diabetes and metabolic syndrome often require two or more antihypertensives to achieve blood pressure (BP) targets. The aim of this sub-analysis was to determine the efficacy and safety of telmisartan 40 or 80 mg plus amlodipine 5 or 10 mg in patients with hypertension, stratified according to certain criteria such as type 2 diabetes mellitus and metabolic syndrome. METHODS: Patients were treated for 8 weeks with telmisartan 20-80 mg plus amlodipine 2.5-10 mg. This post-hoc analysis included patients treated with higher doses, and stratified according to a number of sub-populations (age, race, diabetes, obesity, metabolic syndrome, elevated baseline systolic BP (SBP), renal impairment). RESULTS: Eight weeks' treatment with telmisartan plus amlodipine combinations provided consistent reductions in mean SBP/diastolic BP (DBP) across the different sub-populations, similar to the overall population. SBP/DBP reductions ranged from -13.5 to -34.7/-12.6 to -26.1 mmHg and BP goal rates (<140/90 mmHg) ranged from 29.8-100% for the four key dose combinations of telmisartan plus amlodipine. For the highest dose combination of telmisartan 80 mg plus amlodipine 10 mg, SBP/DBP reduction ranged from -19.1 to -34.7/-16.4 to -22.8 mmHg and goal attainment rate from 66.7% to 87.0%. Across the sub-populations, high SBP and DBP response rates were seen with combination treatment (83.3-97.7% and 75.0-95.7%, respectively, with telmisartan 80 mg plus amlodipine 10 mg). The combination was safe and well tolerated across all sub-populations and the incidence of peripheral oedema with telmisartan 40-80 mg plus amlodipine 10 mg was generally lower than with A10 monotherapy. CONCLUSIONS: Despite small patient numbers in some sub-populations and the post-hoc nature of the analysis, this does show that the combination of telmisartan plus amlodipine provides an effective, safe and well-tolerated antihypertensive treatment for added-risk hypertensive patients.

  • Efficacy and Duration of Benazepril Plus Amlodipine or Hydrochlorthiazide on 24-Hour Ambulatory Systolic Blood Pressure Control
  • 2011
  • Ingår i: Hypertension. - 0194-911X. ; 57:2, s. 174-179
  • Tidskriftsartikel (refereegranskat)abstract
    • The combination of benazepril plus amlodipine was shown to be more effective than benazepril plus hydrochlorothiazide in reducing cardiovascular events in the Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial. There was a small difference in clinic systolic blood pressure between the treatment arms favoring benazepril plus amlodipine. Ambulatory blood pressure monitoring provides a more rigorous estimate of blood pressure effects. A subset of 573 subjects underwent ambulatory blood pressure monitoring during year 2. Readings were obtained every 20 minutes during a 24-hour period. Between-treatment differences (benazepril plus amlodipine versus benazepril plus hydrochlorothiazide) in mean values were analyzed using ANOVA. Treatment comparisons with respect to categorical variables were made using Pearson's chi(2). At year 2, the treatment groups did not differ significantly in 24-hour mean daytime or nighttime blood pressures (values of 123.9, 125.9, and 118.1 mm Hg for benazepril plus amlodipine group versus 122.3, 124.1, and 116.9 for the benazepril plus hydrochlorothiazide group), with mean between-group differences of 1.6, 1.8, and 1.2 mm Hg, respectively. Blood pressure control rates (24-hour mean systolic blood pressure <130 mm Hg on ambulatory blood pressure monitoring) were greater than 80% in both groups. Nighttime systolic blood pressure provided additional risk prediction after adjusting for the effects of drugs. The 24-hour blood pressure control was similar in both treatment arms, supporting the interpretation that the difference in cardiovascular outcomes favoring a renin angiotensin system blocker combined with amlodipine rather than hydrochlorothiazide shown in the ACCOMPLISH trial was not caused by differences in blood pressure, but instead intrinsic properties (metabolic or hemodynamic) of the combination therapies.

  • Rationale and design of the avoiding cardiovascular events through combination therapy in patients living with systolic hypertension (ACCOMPLISH) trial: the first randomized controlled trial to compare the clinical outcome effects of first-line combination therapies in hypertension

    • Reducing blood pressure (BP) to target levels is a major priority in preventing clinical events in hypertension. Typically this requires more than one drug, and recent guidelines on hypertension management therefore recommend starting with combination treatment in many patients. Diuretics have often been part of such therapy, usually paired with angiotensin converting enzyme (ACE) inhibitors or similar agents; but calcium channel blockers are also highly efficacious in reducing BP when combined with ACE inhibitors. In addition, these drug classes, separately and in combination, appear to have vasculoprotective properties. Because the primary goal of treating hypertension is to enhance survival and reduce cardiovascular outcomes, the Rationale and Design of Avoiding Cardiovascular events through COMbination therapy in Patients LIving with Systolic Hypertension (ACCOMPLISH) trial is designed as the first blinded and randomized study to prospectively compare the effects on these endpoints of two antihypertensive combinations, benazapril/hydrochlorothiazide (force titrated to 40/12.5 mg) and amlodipine besylate/benazapril (force titrated to 5/40 mg). The doses can be further titrated to 40/25 mg or 10/40 mg, and other classes of drugs can be added as needed for optimal BP control. The primary study endpoint is a composite of cardiovascular mortality and morbidity. The study will be performed in hypertensive patients (systolic BP > or = 160 mm Hg or currently on antihypertensive therapy) with risk factors for cardiovascular events (prior events, target organ damage, kidney disease, or diabetes). A total of 6300 subjects will be randomized to each group with the expectation that a total of 1642 primary endpoints will occur during a 5-year period, providing 90% power to detect the 15% relative reduction in events (alpha = 0.05) hypothesized to favor the amlodipine besylate/benazapril group. The ACCOMPLISH study will be performed in the United States and Europe. The first patient was randomizedduring 2003, and the trial should conclude in 2008.

    • BACKGROUND: Avoiding Cardiovascular events through COMbination therapy in Patients LIving with Systolic Hypertension (ACCOMPLISH) is an outcome study investigating aggressive antihypertensive combination treatment. It has achieved a larger fraction of overall patients with blood pressure (BP) <140/90 mmHg (73.3%) and diabetic patients <130/80 mmHg (43.3%) at 12 months of follow-up than any other large outcomes trial. We have analyzed baseline predictors of BPs and BP control at 12 months. METHODS: Blinded baseline and 12-month BP was available in 10,173 patients of whom 6132 had diabetes. Univariate and multivariate logistic regression models were used for BP control at 12 months; simple and multiple regression models were used for absolute BP value at 12 months. A stepwise procedure was used to select significant predictors in multivariate analyses. RESULTS: Mean (SD) BP fell from 145.5/80.2 mmHg (18.2/10.7 mmHg) at randomization to 132.7/74.7 mmHg (16/9.6 mmHg) at 12 months. The main baseline predictors of achieving BP control were region (USA), Caucasian race and taking lipid-lowering drugs. The predictors of uncontrolled BP were higher baseline systolic BP values, more previous antihypertensive medications, proteinuria and previous thiazide use. CONCLUSION: Patients in the USA, Caucasians and patients taking lipid-lowering therapy were most likely to reach BP targets with combination therapy. Strong predictors of uncontrolled hypertension were more severe hypertension, an established need for more antihypertensive drugs and target organ damage.

    • Abstract Background. The ACCOMPLISH Trial investigated intensive antihypertensive combination treatment with benazepril + amlodipine (B+A) or benazepril + hydrochlorothiazide (B+H) on cardiovascular outcomes in patients with systolic hypertension. We analyzed the baseline predictors of achieving a systolic blood pressure (SBP) <140 mmHg and achieved SBP level by the end of 12 months in both treatment groups. Methods. Baseline and 12-month SBP was available in 10,506 patients, of whom 6250 had diabetes. Univariate and multivariate logistic regression models were used for SBP control at 12 months and multivariable regression models were used for the prediction of SBP at 12 months. A stepwise procedure was used to select significant (p < 0.001) predictors in multivariate analyses. Results. Mean (+/- SD) BP fell from 145.4/80.1 (+/- 18.3/10.7) mmHg at randomization to 132.8/74.7 (+/- 16.0/9.6) mmHg at 12 months. The main baseline predictors of SBP control <140 mmHg were region (USA >Nordic region) and Caucasian ethnicity in both randomization arms. A higher diastolic BP and the use of lipid lowering agents indicated favorable effects in the B+H arm only. The predictors of uncontrolled SBP were: (i) higher baseline SBP values, (ii) higher number of previous antihypertensive medications in both arms, (iii) the previous use of insulin in the B+A arm, and (iv) pre-trial calcium channel blocker (CCB) use in the B+H arm. Additionally, pre-trial use of thiazides and electrocardiogram (ECG)-left ventricular hypertrophy (LVH) at baseline predicted higher, and smoking lower absolute SBP in the B+A arm and the use of thiazides and proteinuria a higher SBP in the B+H arm. Conclusion. Irrespective of treatment, patients in the USA and Caucasians achieved better SBP control, whereas higher baseline SBP and more previous antihypertensive medications indicated less control. Concomitant use of lipid lowering treatment indicated a better SBP control in the benazepril + hydrochlorothiazide arm. Lastly, insulin use and ECG-LVH in the benazepril + amlodipine arm and proteinuria in the benazepril + hydrochlorothiazide arm indicated poor control.

  • Ingår i: Kidney international. - 1523-1755. ; 81:6, s. 568-76
  • Tidskriftsartikel (refereegranskat)abstract
    • The ACCOMPLISH trial (Avoiding Cardiovascular events through Combination therapy in Patients Living with Systolic Hypertension) was a 3-year multicenter, event-driven trial involving patients with high cardiovascular risk who were randomized in a double-blinded manner to benazepril plus either hydrochlorothiazide or amlodipine and titrated in parallel to reach recommended blood pressure goals. Of the 8125 participants in the United States, 1414 were of self-described Black ethnicity. The composite kidney disease end point, defined as a doubling in serum creatinine, end-stage renal disease, or death was not different between Black and non-Black patients, although the Blacks were significantly more likely to develop a greater than 50% increase in serum creatinine to a level above 2.6 mg/dl. We found important early differences in the estimated glomerular filtration rate (eGFR) due to acute hemodynamic effects, indicating that benazepril plus amlodipine was more effective in stabilizing eGFR compared to benazepril plus hydrochlorothiazide in non-Blacks. There was no difference in the mean eGFR loss in Blacks between therapies. Thus, benazepril coupled to amlodipine was a more effective antihypertensive treatment than when coupled to hydrochlorothiazide in non-Black patients to reduced kidney disease progression. Blacks have a modestly higher increased risk for more advanced increases in serum creatinine than non-Blacks.
