- PublicaciónAcceso abiertoBlood-pressure and cholesterol lowering in persons without cardiovascular disease(2016-04-02) Yusuf, Salim; Lonn, Eva; Pais, Prem; Bosch, Jackie; Lopez-Jaramillo, Patricio; Zhu, Jun; Xavier, Denis; Avezum, Alvaro; Leiter, Lawrence A.; Piegas, Leopoldo S.; Parkhomenko, Alexander; Keltai, Matyas; Keltai, Katalin; Sliwa, Karen; Chazova, Irina; Peters, Ron J.G.; Held, Claes; Yusoff, Khalid; Lewis, Basil S.; Jansky, Petr; Khunti, Kamlesh; Toff, William D.; Reid, Christopher M.; Varigos, John; Accini, Jose Luis; McKelvie, Robert; Pogue, Janice; Jung, Hyejung; Liu, Lisheng; Diaz, Rafael; Dans, Antonio; Dagenais, Gilles; HOPE-3 InvestigatorsBACKGROUND Elevated blood pressure and elevated low-density lipoprotein (LDL) cholesterol increase the risk of cardiovascular disease. Lowering both should reduce the risk of cardiovascular events substantially. METHODS In a trial with 2-by-2 factorial design, we randomly assigned 12,705 participants at intermediate risk who did not have cardiovascular disease to rosuvastatin (10 mg perday) or placebo and to candesartan (16 mg per day) plus hydrochlorothiazide (12.5 mg per day) or placebo. In the analyses reported here, we compared the 3180 participants assigned to combined therapy (with rosuvastatin and the two antihypertensive agents) with the 3168 participants assigned to dual placebo. The first coprimary outcome was the composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke, and the second coprimary outcome additionally included heart failure, cardiac arrest, or revascularization. The median follow-up was 5.6 years. RESULTS The decrease in the LDL cholesterol level was 33.7 mg per deciliter (0.87 mmol per liter) greater in the combined-therapy group than in the dual-placebo group, and the decrease in systolic blood pressure was 6.2 mm Hg greater with combined therapy than with dual placebo. The first coprimary outcome occurred in 113 participants (3.6%) in the combined-therapy group and in 157 (5.0%) in the dual-placebo group (hazard ratio, 0.71; 95% confidence interval [CI], 0.56 to 0.90; P=0.005). The second coprimary outcome occurred in 136 participants (4.3%) and 187 participants (5.9%), respectively (hazard ratio, 0.72; 95% CI, 0.57 to 0.89; P=0.003). Muscle weakness and dizziness were more common in the combined-therapy group than in the dual-placebo group, but the overall rate of discontinuation of the trial regimen was similar in the two groups. CONCLUSIONS The combination of rosuvastatin (10 mg per day), candesartan (16 mg per day), and hydrochlorothiazide (12.5 mg per day) was associated with a significantly lower rate of cardiovascular events than dual placebo among persons at intermediate risk who did not have cardiovascular disease.

- PublicaciónAcceso abiertoBlood-pressure lowering in intermediate-risk persons without cardiovascular disease(2016-04-26) Lonn, Eva; Bosch, Jackie; Lopez-Jaramillo, Patricio; Zhu, Jun; Liu, Lisheng; Pais, Prem; Diaz, Rafael; Xavier, Denis; Sliwa, Karen; Dans, Antonio; Avezum, Alvaro; Leopoldo S., Piegas; Keltai, Katalin; Keltai, Matyas; Chazova, Irina; Peters, Ron J.G.; Held, Claes; Yusoff, Khalid; Lewis, Basil S.; Jansky, Petr; Parkhomenko, Alexander; Khunti, Kamlesh; Toff, William D.; Reid, Christopher M.; Varigos, John; Leiter, Lawrence A.; Molina, Dora I.; McKelvie, Robert; Pogue, Janice; Wilkinson, Joanne; Jung, Hyejung; Dagenais, Gilles; Yusuf, Salim; HOPE-3 InvestigatorsBACKGROUND Antihypertensive therapy reduces the risk of cardiovascular events among high-risk persons and among those with a systolic blood pressure of 160 mm Hg or higher, but its role in persons at intermediate risk and with lower blood pressure is unclear. METHODS In one comparison from a 2-by-2 factorial trial, we randomly assigned 12,705 participants at intermediate risk who did not have cardiovascular disease to receive either candesartan at a dose of 16 mg per day plus hydrochlorothiazide at a dose of 12.5 mg per day or placebo. The first coprimary outcome was the composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke; the second coprimary outcome additionally included resuscitated cardiac arrest, heart failure, and revascularization. The median follow-up was 5.6 years. RESULTS The mean blood pressure of the participants at baseline was 138.1/81.9 mm Hg; the decrease in blood pressure was 6.0/3.0 mm Hg greater in the active-treatment group than in the placebo group. The first coprimary outcome occurred in 260 participants (4.1%) in the active-treatment group and in 279 (4.4%) in the placebo group (hazard ratio, 0.93; 95% confidence interval [CI], 0.79 to 1.10; P=0.40); the second coprimary outcome occurred in 312 participants (4.9%) and 328 participants (5.2%), respectively (hazard ratio, 0.95; 95% CI, 0.81 to 1.11; P=0.51). In one of the three prespecified hypothesis-based subgroups, participants in the subgroup for the upper third of systolic blood pressure (>143.5 mm Hg) who were in the active-treatment group had significantly lower rates of the first and second coprimary outcomes than those in the placebo group; effects were neutral in the middle and lower thirds (P=0.02 and P=0.009, respectively, for trend in the two outcomes). CONCLUSIONS Therapy with candesartan at a dose of 16 mg per day plus hydrochlorothiazide at a dose of 12.5 mg per day was not associated with a lower rate of major cardiovascular events than placebo among persons at intermediate risk who did not have cardiovascular disease.

- PublicaciónAcceso abiertoCholesterol lowering in intermediate-risk persons without cardiovascular disease(2016-05-26) Yusuf, Salim; Bosch, Jackie; Dagenais, Gilles; Zhu, Jun; Xavier, Denis; Liu, Lisheng; Pais, Prem; Lopez-Jaramillo, Patricio; Leiter, Lawrence A.; Dans, Antonio; Avezum, Alvaro; Piegas, Leopoldo S.; Parkhomenko, Alexander; Keltai, Katalin; Keltai, Matyas; Sliwa, Karen; Peters, Ron J.G.; Held, Claes; Chazova, Irina; Yusoff, Khalid; Lewis, Basil S.; Jansky, Petr; Khunti, Kamlesh; Toff, William D.; Reid, Christopher M.; Varigos, John; Sánchez Vallejo, Gregorio; McKelvie, Robert; Pogue, Janice; Jung, Hyejung; Gao, Peggy; Diaz, Rafael; Lonn, Eva; The HOPE-3 InvestigatorsBACKGROUND Previous trials have shown that the use of statins to lower cholesterol reduces the risk of cardiovascular events among persons without cardiovascular disease. Those trials have involved persons with elevated lipid levels or inflammatory markers and involved mainly white persons. It is unclear whether the benefits of statins can be extended to an intermediate-risk, ethnically diverse population without cardiovascular disease. METHODS In one comparison from a 2-by-2 factorial trial, we randomly assigned 12,705 participants in 21 countries who did not have cardiovascular disease and were at intermediate risk to receive rosuvastatin at a dose of 10 mg per day or placebo. The first coprimary outcome was the composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke, and the second coprimary outcome additionally included revascularization, heart failure, and resuscitated cardiac arrest. The median follow-up was 5.6 years. RESULTS The overall mean low-density lipoprotein cholesterol level was 26.5% lower in the rosuvastatin group than in the placebo group. The first coprimary outcome occurred in 235 participants (3.7%) in the rosuvastatin group and in 304 participants (4.8%) in the placebo group (hazard ratio, 0.76; 95% confidence interval [CI], 0.64 to 0.91; P=0.002). The results for the second coprimary outcome were consistent with the results for the first (occurring in 277 participants [4.4%] in the rosuvastatin group and in 363 participants [5.7%] in the placebo group; hazard ratio, 0.75; 95% CI, 0.64 to 0.88; P<0.001). The results were also consistent in subgroups defined according to cardiovascular risk at baseline, lipid level, C-reactive protein level, blood pressure, and race or ethnic group. In the rosuvastatin group, there was no excess of diabetes or cancers, but there was an excess of cataract surgery (in 3.8% of the participants, vs. 3.1% in the placebo group; P=0.02) and muscle symptoms (in 5.8% of the participants, vs. 4.7% in the placebo group; P=0.005). CONCLUSIONS Treatment with rosuvastatin at a dose of 10 mg per day resulted in a significantly lower risk of cardiovascular events than placebo in an intermediate-risk, ethnically diverse population without cardiovascular disease.

- PublicaciónAcceso abiertoNovel Approaches in Primary Cardiovascular Disease Prevention : The HOPE-3 Trial Rationale, Design, and Participants' Baseline Characteristics(2016-03) Lonn, Eva; Bosch, Jackie; Pogue, Janice; Avezum, Alvaro; Chazova, Irina; Dans, Antonio; Diaz, Rafael; Fodor, George J.; Held, Claes; Jansky, Petr; Keltai, Matyas; Keltai, Katalin; Kunti, Kamlesh; Kim, Jae Hyung; Leiter, Lawrence A.; Lewis, Basil S.; Liu, Lisheng; Lopez-Jaramillo, Patricio; Pais, Prem; Parkhomenko, Alexander; Peters, Ron J.G.; Piegas, Leopoldo S.; Reid, Christopher M.; Sliwa, Karen; Toff, William D.; Varigos, John; Xavier, Denis; Yusoff, Khalid; Zhu, Jun; Dagenais, Gilles; Yusuf, Salim; The HOPE-3 InvestigatorsRésumé Introduction Il est possible de faire baisser efficacement et en toute sécurité le cholestérol et la pression artérielle (PA) avec les statines et les antihypertenseurs tout en réduisant de 20 à 30 % les manifestations cardiovasculaires majeures en l’espace de cinq ans chez les personnes à risque élevé. Les données obtenues dans les populations exposées à un risque plus faible sont néanmoins limitées. L’essai HOPE-3 (Heart Outcomes Prevention Evaluation-3) tâche de déterminer si l’abaissement du cholestérol à l’aide d’une statine, l’abaissement de la pression artérielle à l’aide de deux agents antihypertenseurs administrés à raison d’une faible dose et leur association permettent de réduire en toute sécurité les manifestations cardiovasculaires majeures chez les personnes exposées à un risque intermédiaire qui n’ont pas d’antécédents d’événements vasculaires et dont le taux de cholestérol et la PA se situent dans la moyenne. Méthodes Au total, 12 705 femmes et hommes, les unes âgées de 65 ans et plus et les autres de 55 ans et plus, qui présentent au moins un facteur de risque cardiovasculaire et qui n’ont pas de maladie cardiovasculaire connue ni aucune indication ou contre-indication claires aux médicaments à l’étude, ont été répartis aléatoirement pour recevoir de la rosuvastatine à raison de 10 mg par jour ou un placebo et l’association candésartan/hydrochlorothiazide à raison de 16/12,5 mg par jour ou un placebo (plan factoriel 2 × 2). Ces patients seront suivis pendant une moyenne de 5,8 ans. Les principaux paramètres d’évaluation de l’étude combinent le décès d’origine cardiovasculaire, l’infarctus du myocarde non mortel et l’AVC non mortel d’une part, et le décès d’origine cardiovasculaire, l’infarctus du myocarde non mortel, l’AVC non mortel, la réanimation après arrêt cardiaque, l’insuffisance cardiaque et la revascularisation artérielle d’autre part. Résultats Les participants ont été recrutés dans 21 pays situés en Amérique du Nord, en Amérique du Sud, en Europe, en Asie et en Australie. L’âge moyen au moment de la répartition aléatoire était de 66 ans, et 46 % des sujets étaient des femmes. Conclusions L’essai HOPE-3 fournira de nouveaux renseignements sur l’abaissement du taux de cholestérol et de la PA dans des populations exposées à un risque intermédiaire dont le taux de cholestérol et la PA se situent dans la moyenne. Il devrait également fournir des données à l’appui des stratégies de prévention primaire mises en place partout dans le monde (HOPE-3 ClinicalTrials.gov NCT00468923).
