    (The Lancet, 2021-09-25) Joseph, Philip; Roshandel, Gholamreza; Gao, Peggy; Pais, Prem; Lonn, Eva; Xavier, Denis; Avezum, Alvaro; Zhu, Jun; Liu, Lisheng; Sliwa, Karen; Gamra, Habib; Bangdiwala, Shrikant I.; Teo, Koon; Diaz, Rafael; Dans, Antonio; Lopez-Jaramillo, Patricio; Prabhakaran, Dorairaj; Castellano, Jose Maria; Fuster, Valentin; Rodgers, Anthony; Huffman, Mark D.; Bosch, Jackie; Dagenais, Gilles R.; Malekzadeh, Reza; Yusuf, Salim; Polypill Trialists' Collaboration; Masira
    Background In randomised controlled trials, fixed-dose combination treatments (or polypills) have been shown to reduce a composite of cardiovascular disease outcomes in primary prevention. However, whether or not aspirin should be included, effects on specific outcomes, and effects in key subgroups are unknown. Methods We did an individual participant data meta-analysis of large randomised controlled trials (each with ≥1000 participants and ≥2 years of follow-up) of a fixed-dose combination treatment strategy versus control in a primary cardiovascular disease prevention population. We included trials that evaluated a fixed-dose combination strategy of at least two blood pressure lowering agents plus a statin (with or without aspirin), compared with a control strategy (either placebo or usual care). The primary outcome was time to first occurrence of a composite of cardiovascular death, myocardial infarction, stroke, or arterial revascularisation. Additional outcomes included individual cardiovascular outcomes and death from any cause. Outcomes were also evaluated in groups stratified by the inclusion of aspirin in the fixed-dose treatment strategy, and effect sizes were estimated in prespecified subgroups based on risk factors. Kaplan-Meier survival curves and Cox proportional hazard regression models were used to compare strategies. Findings Three large randomised trials were included in the analysis (TIPS-3, HOPE-3, and PolyIran), with a total of 18 162 participants. Mean age was 63·0 years (SD 7·1), and 9038 (49·8%) participants were female. Estimated 10-year cardiovascular disease risk for the population was 17·7% (8·7). During a median follow-up of 5 years, the primary outcome occurred in 276 (3·0%) participants in the fixed-dose combination strategy group compared with 445 (4·9%) in the control group (hazard ratio 0·62, 95% CI 0·53–0·73, p<0·0001). Reductions were also observed for the separate components of the primary outcome: myocardial infarction (0·52, 0·38–0·70), revascularisation (0·54, 0·36–0·80), stroke (0·59, 0·45–0·78), and cardiovascular death (0·65, 0·52–0·81). Significant reductions in the primary outcome and its components were observed in the analyses of fixed-dose combination strategies with and without aspirin, with greater reductions for strategies including aspirin. Treatment effects were similar at different lipid and blood pressure levels, and in the presence or absence of diabetes, smoking, or obesity. Gastrointestinal bleeding was uncommon but slightly more frequent in the fixed-dose combination strategy with aspirin group versus control (19 [0·4%] vs 11 [0·2%], p=0·15). The frequencies of haemorrhagic stroke (10 [0·2%] vs 15 [0·3%]), fatal bleeding (two [<0·1%] vs four [0·1%]), and peptic ulcer disease (32 [0·7%] vs 34 [0·8%]) were low and did not differ significantly between groups. Dizziness was more common with fixed-dose combination treatment (1060 [11·7%] vs 834 [9·2%], p<0·0001). Interpretation Fixed-dose combination treatment strategies substantially reduce cardiovascular disease, myocardial infarction, stroke, revascularisation, and cardiovascular death in primary cardiovascular disease prevention. These benefits are consistent irrespective of cardiometabolic risk factors.

    Global 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.

    Heart 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 Investigators
    Background 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.
