- 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 abiertoCardiovascular and other outcomes postintervention with insulin glargine and omega-3 fatty acids (ORIGINALE)(2016-05) Punthakee, Zubin; Gerstein, Hertzel C.; Bosch Pagans, Jordi; Tyrwhitt, Jessica; Jung, Hyejung; Lee, Shun Fu; Lonn, Eva; Marsden, Tamara; McKelvie, Robert; McQueen, Matthew J.; Morillo, Carlos; Yusuf, Shazzid; Dagenais, Gilles; Diaz, Rafael; Maggioni, Aldo P.; Probstfield, Jeffrey; Ramachandran, Ambady; Riddle, Matthew C.; Rydén, Lars; Badings, Erik; Birkeland, Kare; Cardona Munoz, Ernesto G.; Commerford, Patrick; Davies, Melanie; Fodor, George J.; Gomis, Ramon; Hanefeld, Markolf; Hildebrandt, Per; Kacerovsky Bielesz, Gertrud; Keltai, Matyas; Lanas, Fernando; Lewis, Basil S.; Lopez-Jaramillo, Patricio; Marin Neto, Jose Antonio; Marre, Michel; Mendoza, Ivan; Pan, Chun yue; Pirags, Valdis; Rosenstock, Julio; Spinas, Giatgen A.; Sreenan, Seamus; Syvänne, Mikko; Yale, Jean Francois; ORIGIN Trial InvestigatorsOBJECTIVE The Outcome Reduction With Initial Glargine Intervention (ORIGIN) trial reported neutral effects of insulin glargine on cardiovascular outcomes and cancers and reduced incident diabetes in high–cardiovascular risk adults with dysglycemia after 6.2 years of active treatment. Omega-3 fatty acids had neutral effects on cardiovascular outcomes. The ORIGIN and Legacy Effects (ORIGINALE) study measured posttrial effects of these interventions during an additional 2.7 years. RESEARCH DESIGN AND METHODS Surviving ORIGIN participants attended up to two additional visits. The hazard of clinical outcomes during the entire follow-up period from randomization was calculated. RESULTS Of 12,537 participants randomized, posttrial data were analyzed for 4,718 originally allocated to insulin glargine (2,351) versus standard care (2,367), and 4,771 originally allocated to omega-3 fatty acid supplements (2,368) versus placebo (2,403). Posttrial, small differences in median HbA1c persisted (glargine 6.6% [49 mmol/mol], standard care 6.7% [50 mmol/mol], P = 0.025). From randomization to the end of posttrial follow-up, no differences were found between the glargine and standard care groups in myocardial infarction, stroke, or cardiovascular death (1,185 vs. 1,165 events; hazard ratio 1.01 [95% CI 0.94–1.10]; P = 0.72); myocardial infarction, stroke, cardiovascular death, revascularization, or hospitalization for heart failure (1,958 vs. 1,910 events; 1.03 [0.97–1.10]; P = 0.38); or any cancer (524 vs. 529 events; 0.99 [0.88–1.12]; P = 0.91) or between omega-3 and placebo groups in cardiovascular death (688 vs. 700; 0.98 [0.88–1.09]; P = 0.68) or other outcomes. CONCLUSIONS During >6 years of treatment followed by >2.5 years of observation, insulin glargine had neutral effects on health outcomes and salutary effects on metabolic control, whereas omega-3 fatty acid supplementation had no effect.
- 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.

- PublicaciónRestringidoGlobal mortality variations in patients with heart failure : Results from the International Congestive Heart Failure (INTER-CHF) prospective cohort study(2017-07-01) Lopez-Jaramillo, Patricio; Dokainish, Hisham; Teo, Koon; Zhu, Jun; Roy, Ambuj; AlHabib, Khalid F.; ElSayed, Ahmed; Palileo Villaneuva, Lia; Karaye, Kamilu; Yusoff, Khalid; Orlandini, Andres; Sliwa, Karen; Mondo, Charles; Lanas, Fernando; Prabhakaran, Dorairaj; Badr, Amr; Elmaghawry, Mohamed; Damasceno, Albertino; Tibazarwa, Kemi; Belley Cote, Emilie; Balasubramanian, Kumar; Islam, Shofiqul; Yacoub, Magdi H.; Huffman, Mark D.; Harkness, Karen; Grinvalds, Alex; McKelvie, Robert; Bangdiwala, Shrikant I.; Yusuf, Salim; On behalf of the INTER-CHF Investigators.Background Most data on mortality and prognostic factors in patients with heart failure come from North America and Europe, with little information from other regions. Here, in the International Congestive Heart Failure (INTERCHF) study, we aimed to measure mortality at 1 year in patients with heart failure in Africa, China, India, the Middle East, southeast Asia and South America; we also explored demographic, clinical, and socioeconomic variables associated with mortality. Methods We enrolled consecutive patients with heart failure (3695 [66%] clinic outpatients, 2105 [34%] hospital in patients) from 108 centres in six geographical regions. We recorded baseline demographic and clinical characteristics and followed up patients at 6 months and 1 year from enrolment to record symptoms, medications, and outcomes. Time to death was studied with Cox proportional hazards models adjusted for demographic and clinical variables, medications, socioeconomic variables, and region. We used the explained risk statistic to calculate the relative contribution of each level of adjustment to the risk of death. Findings We enrolled 5823 patients within 1 year (with 98% follow-up). Overall mortality was 16·5%: highest in Africa (34%) and India (23%), intermediate in southeast Asia (15%), and lowest in China (7%), South America (9%), and the Middle East (9%). Regional differences persisted after multivariable adjustment. Independent predictors of mortality included cardiac variables (New York Heart Association Functional Class III or IV, previous admission for heart failure, and valve disease) and non-cardiac variables (body-mass index, chronic kidney disease, and chronic obstructive pulmonary disease). 46% of mortality risk was explained by multivariable modelling with these variables; however, the remainder was unexplained. Interpretation Marked regional differences in mortality in patients with heart failure persisted after multivariable adjustment for cardiac and non-cardiac factors. Therefore, variations in mortality between regions could be the result of health-care infrastructure, quality and access, or environmental and genetic factors. Further studies in large, global cohorts are needed. Funding The study was supported by Novartis.
- PublicaciónAcceso abiertoHeart Failure in Africa, Asia, the Middle East and South America: The INTER-CHF study(2016-02) Dokainish, Hisham; Teo, Koon; Zhu, Jun; Roy, Ambuj; AlHabib, Khalid F.; ElSayed, Ahmed; Palileo Villaneuva, Lia; Lopez-Jaramillo, Patricio; Karaye, Kamilu; Yusoff, Khalid; Orlandini, Andres; Sliwa, Karen; Mondo, Charles; Lanas, Fernando; Prabhakaran, Dorairaj; Badr, Amr; Elmaghawry, Mohamed; Damasceno, Albertino; Tibazarwa, Kemi; Belley Cote, Emilie; Balasubramanian, Kumar; Yacoub, Magdi H.; Huffman, Mark D.; Harkness, Karen; Grinvalds, Alex; McKelvie, Robert; Yusuf, Salim; The INTER-CHF InvestigatorsBackground There are few data on heart failure (HF) patients from Africa, Asia, the Middle East and South America. Methods INTER-CHF is a prospective study that enrolled HF patients in 108 centers in 16 countries from 2012 to 2014. Consecutive ambulatory or hospitalized adult patients with HF were enrolled. Baseline data were recorded on sociodemographics, clinical characteristics, HF etiology and treatments. Age- and sex-adjusted results are reported. Results We recruited 5813 HF patients: mean(SE) age = 59(0.2) years, 39% female, 65% outpatients, 31% from rural areas, 26% with HF with preserved ejection fraction, with 1294 from Africa, 2661 from Asia, 1000 from the Middle-East, and 858 from South America. Participants from Africa—closely followed by Asians—were younger, had lower literacy levels, and were less likely to have health or medication insurance or be on beta-blockers compared with participants from other regions, but were most likely to be in NYHA class IV. Participants from South America were older, had higher insurance and literacy levels, and, along with Middle Eastern participants, were more likely to be on beta-blockers, but had the lowest proportion in NYHA IV. Ischemic heart disease was the most common HF etiology in all regions except Africa where hypertensive heart disease was most common. Conclusions INTER-CHF describes significant regional variability in socioeconomic and clinical factors, etiologies and treatments in HF patients from Africa, Asia, the Middle East and South America. Opportunities exist for improvement in health/medication insurance rates and proportions of patients on beta blockers, particularly in Africa and Asia.
