    • We conducted a three-stage genetic study to identify susceptibility loci for type 2 diabetes (T2D) in east Asian populations. We followed our stage 1 meta-analysis of eight T2D genome-wide association studies (6,952 cases with T2D and 11,865 controls) with a stage 2 in silico replication analysis (5,843 cases and 4,574 controls) and a stage 3 de novo replication analysis (12,284 cases and 13,172 controls). The combined analysis identified eight new T2D loci reaching genome-wide significance, which mapped in or near GLIS3, PEPD, FITM2-R3HDML-HNF4A, KCNK16, MAEA, GCC1-PAX4, PSMD6 and ZFAND3. GLIS3, which is involved in pancreatic beta cell development and insulin gene expression, is known for its association with fasting glucose levels. The evidence of an association with T2D for PEPD and HNF4A has been shown in previous studies. KCNK16 may regulate glucose-dependent insulin secretion in the pancreas. These findings, derived from an east Asian population, provide new perspectives on the etiology of T2D.

  • Multimorbidity in patients with acute heart failure across world regions and country income levels (REPORT-HF): a prospective, multicentre, global cohort study
  • 2023
  • Ingår i: The Lancet Global Health. - : ELSEVIER SCI LTD. - 2214-109X. ; 11:12, s. e1874-e1884
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Multimorbidity (two or more comorbidities) is common among patients with acute heart failure, but comprehensive global information on its prevalence and clinical consequences across different world regions and income levels is scarce. This study aimed to investigate the prevalence of multimorbidity and its effect on pharmacotherapy and prognosis in participants of the REPORT-HF study.Methods REPORT-HF was a prospective, multicentre, global cohort study that enrolled adults (aged >= 18 years) admitted to hospital with a primary diagnosis of acute heart failure from 358 hospitals in 44 countries on six continents. Patients who currently or recently participated in a clinical treatment trial were excluded. Follow-up data were collected at 1-year post-discharge. The primary outcome was 1-year post-discharge mortality. All patients in the REPORT-HF cohort with full data on comorbidities were eligible for the present study. We stratified patients according to the number of comorbidities, and countries by world region and country income level. We used one-way ANOVA, chi(2) test, or Mann-Whitney U test for comparisons between groups, as applicable, and Cox regression to analyse the association between multimorbidity and 1-year mortality.Findings Between July 23, 2014, and March 24, 2017, 18 553 patients were included in the REPORT-HF study. Of these, 18 528 patients had full data on comorbidities, of whom 11 360 (61%) were men and 7168 (39%) were women. Prevalence rates of multimorbidity were lowest in southeast Asia (72%) and highest in North America (92%). Fewer patients from lower-middle-income countries had multimorbidity than patients from high-income countries (73% vs 85%, p<0 center dot 0001). With increasing comorbidity burden, patients received fewer guideline-directed heart failure medications, yet more drugs potentially causing or worsening heart failure. Having more comorbidities was associated with worse outcomes: 1-year mortality increased from 13% (no comorbidities) to 26% (five or more comorbidities). This finding was independent of common baseline risk factors, including age and sex. The population-attributable fraction of multimorbidity for mortality was higher in high-income countries than in upper-middle-income or lower-middle-income countries (for patients with five or more comorbidities: 61% vs 27% and 31%, respectively).Interpretation Multimorbidity is highly prevalent among patients with acute heart failure across world regions, especially in high-income countries, and is associated with higher mortality, less prescription of guideline-directed heart failure pharmacotherapy, and increased use of potentially harmful medications.

  • A comprehensive population-based characterization of heart failure with mid-range ejection fraction
  • 2017
  • Ingår i: European Journal of Heart Failure. - : WILEY. - 1388-9842 .- 1879-0844. ; 19:12, s. 1624-1634
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: Clinical features and outcomes in the novel phenotype heart failure with mid-range ejection fraction [HFmrEF, ejection fraction (EF) 40-49%] were compared with heart failure with reduced EF (HFrEF, EF < 40%) and preserved EF (HFpEF, EF >= 50%).Methods and results: In the Swedish Heart Failure Registry, we assessed the association between baseline characteristics and EF group using multivariable logistic regressions, and the association between EF group and all-cause mortality using multivariable Cox regressions. Of 42 061 patients, 56% had HFrEF, 21% had HFmrEF, and 23% had HFpEF. Characteristics were continuous for age (72 +/- 12 vs. 74 +/- 12 vs. 77 +/- 11 years), proportion of women (29% vs. 39% vs. 55%), and 13 other characteristics. Coronary artery disease (CAD) was distinctly more common in HFrEF (54%) and HFmrEF (53%) vs. HFpEF (42%); adjusted odds ratio for CAD in HFmrEF vs. HFpEF was 1.52 [95% confidence interval (CI) 1.41-1.63]. For six additional characteristics HFmrEF resembled HFrEF, for seven characteristics HFmrEF resembled HFpEF, and for 10 characteristics there was no pattern. The adjusted hazard ratio (HR) for mortality in HFrEF vs. HFpEF was 1.35 (95% CI 1.14-1.60) at 30 days, 1.26 (95% CI 1.17-1.35) at 1 year, and 1.20 (95% CI 1.14-1.26) at 3 years. In contrast, HFmrEF and HFpEF had a similar prognosis (HR 1.06, 95% CI 0.86-1.30 at 30 days; HR 1.08, 95% CI 1.00-1.18 at 1 year; and HR 1.06, 95% CI 1.00-1.12 at 3 years). Three-year mortality was higher in HFmrEF than in HFpEF in the presence of CAD (HR 1.11, 95% CI 1.02-1.21), but not in the absence of CAD (HR 1.02, 95% CI 0.94-1.12; P for interaction < 0.001).Conclusions: HFmrEF was an intermediate phenotype, except that CAD was more common in HFmrEF and HFrEF vs. HFpEF, crude all-cause mortality was lower in HFmrEF and HFrEF, adjusted all-cause mortality was lower in HFmrEF and HFpEF, and CAD portended a higher adjusted risk of death in HFmrEF and HFrEF.

  • Changing health related quality of life and outcomes in heart failure by age, sex and subtype
  • 2023
  • Ingår i: eClinicalMedicine. - : ELSEVIER. - 2589-5370. ; 64
  • Tidskriftsartikel (refereegranskat)abstract
    • Background There are calls to integrate serial recordings of health related quality of life (HRQoL) into routine care, clinical trials and prognosis. Little is known about the relationship between change in HRQoL and outcomes in heart failure (HF) patients by age, sex and HF subtype. Method From the Swedish Heart Failure Registry (SwedeHF; 2008-2019), patients were categorised by reduced (<40%, HFrEF), mildly-reduced (40-49%, HFmrEF) and preserved (>= 50%, HFpEF) ejection fraction. HRQoL was measured using Euro-QoL-5D visual analogue scale (EQ5D-vas), collected at baseline and 1-year. Baseline EQ5Dvas scores were categorised by: "best" (76-100), "good" (51-75), "bad" (26-50), and "worst" (0-25). Change in EQ5D-vas was categorised as 'no significant change' (<5 points increase/decrease); some worsening (5-9 points decrease); considerable worsening (>= 10 points decrease); some improvement (5-9 points increase); considerable improvement (>= 10 points increase). Associations with admission and death were estimated and interactions with patient sub-groups tested. Findings Among 23,553 patients (median age 74 [66-81] years, 8000 [34%] female), baseline EQ5D-vas was worse in older patients, women, and those with HFpEF compared to their respective counterparts. Compared to patients with the "best" EQ5D-vas, the adjusted associations for admission for those with "good", "bad" and "worst" EQ5D-vas were, respectively: HR 1.09 (1.04, 1.14), 1.27 (1.21, 1.33) and 1.39 (1.28, 1.51). Compared to no significant change in EQ5D-vas, the adjusted estimates for admission following some improvement, considerable improvement, some worsening and considerable worsening were, respectively: HR 0.91 (0.82, 1.01), 0.75 (0.70, 0.81), 1.04 (0.92, 1.16) and 1.25 (1.16, 1.35). Results were similar amongst groups and for HF admission and death. Interpretation Change in HRQoL was an independent indicator of risk of admission and death in people with all HF subtypes, irrespective of age and sex.

  • Developing a core outcome set for patient-reported symptom monitoring to reduce hospital admissions for patients with heart failure
  • 2022
  • Ingår i: European Journal of Cardiovascular Nursing. - : Oxford University Press. - 1474-5151 .- 1873-1953. ; 21:8, s. 830-839
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims In patients with heart failure (HF), hospitalization rates are increasing, particularly for non-HF causes and over half may be avoidable. Self-monitoring of symptoms plays a key part in the early identification of deterioration. Our objective was to develop expert consensus for a core outcome set (COS) of symptoms to be monitored by patients, using validated single-item patient-reported outcome measures (PROMs), focused on the key priority of reducing admissions in HF. Methods and results A rigorous COS development process incorporating systematic review, modified e-Delphi and nominal group technique (NGT) methods. Participants included 24 HF patients, 4 carers, 29 HF nurses, and 9 doctors. In three Delphi and NGT rounds, participants rated potential outcomes on their importance before a HF or a non-HF admission using a 5-point Likert scale. Opinion change between rounds was assessed and a two-thirds threshold was used for outcome selection. Item generation using systematic review identified 100 validated single-item PROMs covering 34 symptoms or signs, relevant to admission for people with HF. De-duplication and formal consensus processes, resulted in a COS comprising eight symptoms and signs; shortness of breath, arm or leg swelling, abdomen bloating, palpitations, weight gain, chest pain, anxiety, and overall health. In the NGT, a numerical rating scale was selected as the optimal approach to symptom monitoring. Conclusion Recognition of a range of HF-specific and general symptoms, alongside comorbidities, is an important consideration for admission prevention. Further work is needed to validate and integrate the COS in routine care with the aim of facilitating faster identification of clinical deterioration. [GRAPHICS] .

  • Patient-Reported Status and Heart Failure Outcomes in Asia by Sex, Ethnicity, and Socioeconomic Status
  • 2023
  • Ingår i: JACC. Asia. - : Elsevier. - 2772-3747. ; 3:3, s. 349-362
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In heart failure (HF), symptoms and health-related quality of life (HRQoL) are known to vary among different HF subgroups, but evidence on the association between changing HRQoL and outcomes has not been evaluated.Objectives: The authors sought to investigate the relationship between changing symptoms, signs, and HRQoL and outcomes by sex, ethnicity, and socioeconomic status (SES).Methods: Using the ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) Registry, we investigated associations between the 6-month change in a "global" symptoms and signs score (GSSS), Kansas City Cardiomyopathy Questionnaire overall score (KCCQ-OS), and visual analogue scale (VAS) and 1-year mortality or HF hospitalization.Results: In 6,549 patients (mean age: 62 ± 13 years], 29% female, 27% HF with preserved ejection fraction), women and those in low SES groups had higher symptom burden but lower signs and similar KCCQ-OS to their respective counterparts. Malay patients had the highest GSSS (3.9) and lowest KCCQ-OS (58.5), and Thai/Filipino/others (2.6) and Chinese patients (2.7) had the lowest GSSS scores and the highest KCCQ-OS (73.1 and 74.6, respectively). Compared to no change, worsening of GSSS (>1-point increase), KCCQ-OS (≥10-point decrease) and VAS (>1-point decrease) were associated with higher risk of HF admission/death (adjusted HR: 2.95 [95% CI: 2.14-4.06], 1.93 [95% CI: 1.26-2.94], and 2.30 [95% CI: 1.51-3.52], respectively). Conversely, the same degrees of improvement in GSSS, KCCQ-OS, and VAS were associated with reduced rates (HR: 0.35 [95% CI: 0.25-0.49], 0.25 [95% CI: 0.16-0.40], and 0.64 [95% CI: 0.40-1.00], respectively). Results were consistent across all sex, ethnicity, and SES groups (interaction P > 0.05).Conclusions: Serial measures of patient-reported symptoms and HRQoL are significant and consistent predictors of outcomes among different groups with HF and provide the potential for a patient-centered and pragmatic approach to risk stratification.

  • Different relationships between pulse pressure and mortality in heart failure with reduced, mid-range and preserved ejection fraction
  • 2018
  • Ingår i: International Journal of Cardiology. - : ELSEVIER IRELAND LTD. - 0167-5273 .- 1874-1754. ; 254, s. 203-209
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives/Background: In heart failure (HF), pulse pressure (PP) may reflect both vascular stiffness and left ventricular function, but its prognostic role in relation to ejection fraction (EF) is poorly understood. Methods: In the Swedish Heart Failure Registry, we investigated the association between PP and 1-year mortality in patients with HF and reduced (HFrEF, amp;lt;40%), mid-range (HFmrEF, 40-49%) and preserved EF (HFpEF, amp;gt;= 50%), using multivariable logistic regression and restricted cubic splines. Results: Among 36,770 patients discharged alive or enrolled as out-patients with 1-year follow-up (mean age 74 +/- 12 years, 63% men, 56% HFrEF, 21% HFmrEF, 23% HFpEF), crude one-year mortality was 18%. Mean PP increased across EF groups: 51 +/- 16 in HFrEF, 57 +/- 18 in HFmrEF, 60 +/- 19 mm Hg in HFpEF. In crude regression splines, the association between PP and mortality was U-shaped in HFmrEF and HFpEF, but curvilinear with only low PP associated with mortality in HFrEF. In multivariable analyses, a significant interaction by EF group and PP was observed (p(interaction) = 0.015): low PP was associated with higher mortality in HFrEF (adjusted OR [1st vs. 4th quintile] = 1.40, 95% CI 1.18-1.67) and HFpEF (1.43, 1.14-1.81) but only by trend in HFmrEF; high PP had a trend towards higher mortality in HFmrEF (5th vs. 3rd quintile = 1.30, 1.00-1.69) and HFpEF (1.25, 0.98-1.61). Conclusions: The association between PP and mortality in HF was influenced by EF. Low PP was independently associated with mortality in HFrEF and HFpEF and by trend in HFmrEF. High PP was independently associated with mortality by trend in HFmrEF and HFpEF. (C) 2017 Elsevier B.V. All rights reserved.

  • Global disparities in prescription of guideline-recommended drugs for heart failure with reduced ejection fraction
  • 2022
  • Ingår i: European Heart Journal. - : OXFORD UNIV PRESS. - 0195-668X .- 1522-9645. ; 43:23, s. 2224-2234
  • Tidskriftsartikel (refereegranskat)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, beta-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 beta-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.
