Heart failure is a global public health problem, affecting a large number of individuals from low-income and middle-income countries. REPORT-HF is, to our knowledge, the first prospective global ...registry collecting information on patient characteristics, management, and prognosis of acute heart failure using a single protocol. The aim of this study was to investigate differences in 1-year post-discharge mortality according to region, country income, and income inequality.
Patients were enrolled during hospitalisation for acute heart failure from 358 centres in 44 countries on six continents. We stratified countries according to a modified WHO regional classification (Latin America, North America, western Europe, eastern Europe, eastern Mediterranean and Africa, southeast Asia, and western Pacific), country income (low, middle, high) and income inequality (according to tertiles of Gini index). Risk factors were identified on the basis of expert opinion and knowledge of the literature.
Of 18 102 patients discharged, 3461 (20%) died within 1 year. Important predictors of 1-year mortality were old age, anaemia, chronic kidney disease, presence of valvular heart disease, left ventricular ejection fraction phenotype (heart failure with reduced ejection fraction HFrEF vs preserved ejection fraction HFpEF), and being on guideline-directed medical treatment (GDMT) at discharge (p<0·0001 for all). Patients from eastern Europe had the lowest 1-year mortality (16%) and patients from eastern Mediterranean and Africa (22%) and Latin America (22%) the highest. Patients from lower-income countries (ie, ≤US$3955 per capita; hazard ratio 1·58, 95% CI 1·41–1·77), or with greater income inequality (ie, from the highest Gini tertile; 1·25, 1·13–1·38) had a higher 1-year mortality compared with patients from regions with higher income (ie, >$12 235 per capita) or lower income inequality (ie, from the lowest Gini tertile). Compared with patients with HFrEF, patients with HFpEF had a lower 1-year mortality with little variation by income level (pinteraction for HFrEF vs HFpEF <0·0001).
Acute heart failure is associated with a high post-discharge mortality, particularly in patients with HFrEF from low-income regions with high income inequality. Regional differences exist in the proportion of eligible patients discharged on GDMT, which was strongly associated with mortality and might reflect lack of access to post-discharge care and prescribing of GDMT.

Asians are predisposed to a lean heart failure (HF) phenotype. Data on the 'obesity paradox', reported in Western populations, are scarce in Asia and have only utilised the traditional classification ...of body mass index (BMI). We aimed to investigate the association between obesity (defined by BMI and abdominal measures) and HF outcomes in Asia.
Utilising the Asian Sudden Cardiac Death in Heart Failure (ASIAN-HF) registry (11 Asian regions including Taiwan, Hong Kong, China, India, Malaysia, Thailand, Singapore, Indonesia, Philippines, Japan, and Korea; 46 centres with enrolment between 1 October 2012 and 6 October 2016), we prospectively examined 5,964 patients with symptomatic HF (mean age 61.3 ± 13.3 years, 26% women, mean BMI 25.3 ± 5.3 kg/m2, 16% with HF with preserved ejection fraction HFpEF; ejection fraction ≥ 50%), among whom 2,051 also had waist-to-height ratio (WHtR) measurements (mean age 60.8 ± 12.9 years, 24% women, mean BMI 25.0 ± 5.2 kg/m2, 7% HFpEF). Patients were categorised by BMI quartiles or WHtR quartiles or 4 combined groups of BMI (low, <24.5 kg/m2 lean, or high, ≥24.5 kg/m2 obese) and WHtR (low, <0.55 thin, or high, ≥0.55 fat). Cox proportional hazards models were used to examine a 1-year composite outcome (HF hospitalisation or mortality). Across BMI quartiles, higher BMI was associated with lower risk of the composite outcome (ptrend < 0.001). Contrastingly, higher WHtR was associated with higher risk of the composite outcome. Individuals in the lean-fat group, with low BMI and high WHtR (13.9%), were more likely to be women (35.4%) and to be from low-income countries (47.7%) (predominantly in South/Southeast Asia), and had higher prevalence of diabetes (46%), worse quality of life scores (63.3 ± 24.2), and a higher rate of the composite outcome (51/232; 22%), compared to the other groups (p < 0.05 for all). Following multivariable adjustment, the lean-fat group had higher adjusted risk of the composite outcome (hazard ratio 1.93, 95% CI 1.17-3.18, p = 0.01), compared to the obese-thin group, with high BMI and low WHtR. Results were consistent across both HF subtypes (HFpEF and HF with reduced ejection fraction HFrEF; pinteraction = 0.355). Selection bias and residual confounding are potential limitations of such multinational observational registries.
In this cohort of Asian patients with HF, the 'obesity paradox' is observed only when defined using BMI, with WHtR showing the opposite association with the composite outcome. Lean-fat patients, with high WHtR and low BMI, have the worst outcomes. A direct correlation between high WHtR and the composite outcome is apparent in both HFpEF and HFrEF.

Abstract
Background
Heart failure (HF) is a global challenge, with lower- and middle-income countries (LMICs) carrying a large share of the burden. Treatment for HF with reduced ejection fraction ...(HFrEF) improves survival but is often underused. Economic factors might have an important effect on the use of medicines.
Methods and results
This analysis assessed prescription rates and doses of renin–angiotensin system (RAS) inhibitors, β-blockers, and mineralocorticoid receptor antagonists at discharge and 6-month follow-up in 8669 patients with HFrEF (1458 from low-, 3363 from middle-, and 3848 from high-income countries) hospitalized for acute HF in 44 countries in the prospective REPORT-HF study. We investigated determinants of guideline-recommended treatments and their association with 1-year mortality, correcting for treatment indication bias.
Only 37% of patients at discharge and 34% of survivors at 6 months were on all three medication classes, with lower proportions in LMICs than high-income countries (19 vs. 41% at discharge and 15 vs. 37% at 6 months). Women and patients without health insurance, or from LMICs, or without a scheduled medical follow-up within 6 months of discharge were least likely to be on guideline-recommended medical therapy at target doses, independent of confounders. Being on ≥50% of guideline-recommended doses of RAS inhibitors, and β-blockers were independently associated with better 1-year survival, regardless of country income level.
Conclusion
Patients with HFrEF in LMICs are less likely to receive guideline-recommended drugs at target doses. Improved access to medications and medical care could reduce international disparities in outcome.

The primary aim of the current study was to investigate global differences in prevalence, association with outcome, and treatment of ischemic heart disease (IHD) in patients with acute heart failure ...(AHF) in the REPORT-HF (International Registry to Assess Medical Practice With Longitudinal Observation for Treatment of Heart Failure) registry.
Data on IHD in patients with AHF are primarily from Western Europe and North America. Little is known about global differences in treatment and prognosis of patients with IHD and AHF.
A total of 18,539 patients with AHF were prospectively enrolled from 44 countries and 365 centers in the REPORT-HF registry. Patients with a history of coronary artery disease, an ischemic event causing admission for AHF, or coronary revascularization were classified as IHD. Clinical characteristics, treatment, and outcomes of patients with and without IHD were explored.
Compared with 8,766 (47%) patients without IHD, 9,773 (53%) patients with IHD were older, more likely to have a left ventricular ejection fraction <40% (heart failure with reduced ejection fraction HFrEF), and reported more comorbidities. IHD was more common in lower income compared with high-income countries (61% vs. 48%). Patients with IHD from countries with low health care expenditure per capita or without health insurance less likely underwent coronary revascularization or used anticoagulants at discharge. IHD was independently associated with worse cardiovascular death (hazard ratio: 1.21; 95% confidence interval: 1.09 to 1.35). The association between IHD and cardiovascular death was stronger in HFrEF compared with heart failure with preserved ejection fraction (p
<0.001).
In this large global contemporary cohort of patients with AHF, IHD was more common in low-income countries and conveyed worse 1-year mortality, especially in HFrEF. Patients in regions with the greatest burden of IHD were less likely to receive coronary revascularization and treatment for IHD.

Frailty is common in patients with heart failure (HF) and can adversely impact outcomes.
This study examined the prevalence of frailty among Asian patients with HF, its association with 1-year ...outcomes, and if race-ethnicity, HF subtypes, and sex modify this relationship.
In the multinational ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) registry, a baseline frailty index (FI) was constructed using a cumulative deficits approach with 48 baseline variables, and patients were followed for the 1-year primary outcome of all-cause death or HF hospitalization.
Among 3,881 participants (age 61 ± 13 years, 27% female), the mean FI was 0.28 ± 0.11, and 69% were frail (FI >0.21). Higher FI was associated with older age, Malay ethnicity, and Southeast Asian residency. While comorbidities were more frequent in frail patients (by definition), body mass index was not different across frailty classes. Compared with FI class 1 (<0.21, nonfrail), FI class 2 (0.21-0.31) and FI class 3 (>0.31) had increased risk of the 1-year composite outcome (hazard ratios of 1.84 95% confidence interval (CI): 1.42-2.38 and 4.51 95% CI: 3.59-5.67, respectively), even after multivariable adjustment (adjusted hazard ratios of 1.49 95% CI: 1.13-1.97 and 2.69 95% CI: 2.06-3.50, respectively). Race-ethnicity modified the association of frailty with the composite outcome (Pinteraction = 0.0097), wherein the impact of frailty was strongest among Chinese patients. The association between frailty and outcomes did not differ between men and women (Pinteraction = 0.186) or for HF with reduced ejection fraction versus HF with preserved ejection fraction (Pinteraction = 0.094).
Most Asian patients with HF are frail despite relatively young age. Our results reveal specific ethnic (Malay) and regional (Southeast Asia) predisposition to frailty and highlight its prognostic importance, especially in Chinese individuals.
