    • AIMS: The importance of intraventricular conduction delay (IVCD), incidence of new IVCD and its relationship to outcomes in heart failure and reduced ejection fraction (HFrEF) is not well studied. We addressed these questions in the PARADIGM-HF and ATMOSPHERE trials. METHODS AND RESULTS: Risk of the primary composite outcome of cardiovascular death or HF hospitalization and all-cause mortality were estimated by use of Cox regression according to baseline QRS duration and morphology in 11,861 patients without an intracardiac device. At baseline, 1,789 (15.1%) patients had left bundle branch block (LBBB), 524 (4.4%) RBBB, 454 (3.8%) non-specific IVCD, 2588 (21.8%) "mildly abnormal" QRS (110-129 milliseconds [ms]) and 6506 (54.9%) QRS <110 ms. During a median follow-up of 2.5 years, the risk of the primary composite endpoint was higher among those with a wide QRS, irrespective of morphology: hazard ratios (95% CI) LBBB 1.36 (1.23, 1.50), RBBB 1.54 (1.31, 1.79), nonspecific IVCD 1.65 (1.40, 1.94) and QRS 110-129 ms 1.35 (95% CI 1.23, 1.47), compared with QRS duration <110 ms. A total of 1,234 (15.6%) patients developed new-onset QRS-widening >/=130 ms (6.1 per 100 py). Incident LBBB occurred in 495 (6.3%) patients (2.4 per 100 py) and was associated with a higher risk of the primary composite outcome; HR 1.42 (1.12, 1.82). CONCLUSION: In patients with HFrEF, a wide QRS was associated with worse clinical outcomes irrespective of morphology. The annual incidence of new-onset LBBB was around 2.5%, and associated with a higher risk of adverse outcomes, highlighting the importance of repeat ECG review.

  • Treatment with insulin is associated with worse outcome in patients with chronic heart failure and diabetes
  • 2018
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842. ; 20:5, s. 888-895
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims Up to one-third of patients with diabetes mellitus and heart failure (HF) are treated with insulin. As insulin causes sodium retention and hypoglycaemia, its use might be associated with worse outcomes. Methods and results We examined two datasets: 24 012 patients with HF from four large randomized trials and an administrative database of 4 million individuals, 103 857 of whom with HF. In the former, survival was examined using Cox proportional hazards models adjusted for baseline variables and separately for propensity scores. Fine-Gray competing risk regression models were used to assess the risk of hospitalization for HF. For the latter, a case-control nested within a population-based cohort study was conducted with propensity score. Prevalence of diabetes mellitus at study entry ranged from 25.5% to 29.5% across trials. Insulin alone or in combination with oral hypoglycaemic drugs was prescribed at randomization to 24.4% to 34.5% of the patients with diabetes. The rates of death from any cause and hospitalization for HF were higher in patients with vs. without diabetes, and highest of all in patients prescribed insulin [propensity score pooled hazard ratio for all-cause mortality 1.27 (1.16-1.38), for HF hospitalization 1.23 (1.13-1.33)]. In the administrative registry, insulin prescription was associated with a higher risk of all-cause death [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.87-2.19] and rehospitalization for HF (OR 1.42, 95% CI 1.32-1.53). Conclusions Whether insulin use is associated with poor outcomes in HF should be investigated further with controlled trials, as should the possibility that there may be safer alternative glucose-lowering treatments for patients with HF and type 2 diabetes mellitus.

  • Clinical Outcomes Related to Background Diuretic Use and New Diuretic Initiation in Patients With HFrEF
  • 2022
  • Ingår i: Jacc-Heart Failure. - : Elsevier BV. - 2213-1779. ; 10:6, s. 415-427
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND Up to 20% of patients in heart failure with reduced ejection fraction (HFrEF) trials are not taking diuretic agents at baseline, but little is known about them. OBJECTIVES The aim of this study was to examine outcomes in patients with HFrEF not taking diuretic medications and after diuretic medications are started. METHODS Patient characteristics and outcomes were compared between patients taking or not taking diuretic drugs at baseline in the ATMOSPHERE (Aliskiren Trial of Minimizing Outcomes for Patients With Heart Failure) and PARADIGM-HF (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure Trial) trials combined. Patients starting diuretic medications were also compared with those remaining off diuretic drugs during follow-up. Symptoms (Kansas City Cardiomyopathy Questionnaire Clinical Summary Score [KCCQ-CSS]), hospitalization for worsening heart failure (HF), mortality, and kidney function (estimated glomerular filtration rate slope) were examined. RESULTS At baseline, the 3,079 of 15,415 patients (20%) not taking diuretic medications had a less severe HF profile, less neurohumoral activation, and better kidney function. They were less likely to experience the primary outcome (hospitalization for HF or cardiovascular death) than patients taking diuretic agents (adjusted HR: 0.77; 95% CI: 0.74-0.80; P < 0.001) and death of any cause. Commencement of a diuretic drug was associated with higher subsequent risk for death (adjusted HR: 2.05; 95% CI: 1.99-2.11; P < 0.001) and greater decreases in KCCQ-CSS and estimated glomerular filtration rate. The 5 strongest predictors of initiation of diuretic medications were higher N-terminal pro-B-type natriuretic peptide, higher body mass index, older age, history of diabetes, and worse KCCQ-CSS. In PARADIGM-HF, fewer patients who were treated with sacubitril/valsartan commenced diuretic agents (OR: 0.72; 95% CI: 0.58-0.88; P = 0.002). CONCLUSIONS Patients with HFrEF not taking diuretic medications and those who remained off them had better outcomes than patients treated with diuretic agents or who commenced them.

  • Differential Impact of Heart Failure With Reduced Ejection Fraction on Men and Women
  • 2019
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier BV. - 0735-1097. ; 73:1, s. 29-40
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND Heart failure (HF) trials initiated in the last century highlighted many differences between men and women. Of particular concern was undertreatment of women compared with men, but much has changed during the past 20 years. OBJECTIVES This study sought to identify these changes, which may give a new perspective on the management of, and outcomes in, women with HF. METHODS The study analyzed 12,058 men and 3,357 women enrolled in 2 large HF with reduced ejection fraction (HFrEF) trials with near identical inclusion and exclusion criteria and the same principal outcomes. Outcomes were adjusted for other prognostic variables including N-terminal pro-B-type natriuretic peptide. RESULTS Women were older and more often obese than men were, had slightly higher systolic blood pressure and heart rate, and were less likely to have most comorbidities, except hypertension. Women had more symptoms and signs (e.g., pedal edema 23.4% vs 19.9%; p < 0.0001) and worse quality of life-median Kansas City Cardiomyopathy Questionnaire Clinical Summary Score 71.3 (interquartile range: 53.4 to 86.5) versus 81.3 (interquartile range: 65.1 to 92.7; p < 0.0001)-despite similar left ventricular ejection fraction and N-terminal pro-B-type natriuretic peptide. However, women had lower mortality (adjusted hazard ratio: 0.68; 95% confidence interval: 0.62 to 0.74; p < 0.001) and risk of HF hospitalization (hazard ratio: 0.80; 95% confidence interval: 0.72 to 0.89; p < 0.001). Diuretics and anticoagulants were underutilized in women. Device therapy was underused in both men and women, but more so in women (e.g., defibrillator 8.6% vs. 16.6%; p < 0.0001). CONCLUSIONS Although women with HFrEF live longer than men, their additional years of life are of poorer quality, with greater self-reported psychological and physical disability. The explanation for this different sex-related experience of HFrEF is unknown as is whether physicians recognize it. Women continue to receive suboptimal treatment, compared with men, with no obvious explanation for this shortfall.

  • Income Inequality and Outcomes in Heart Failure A Global Between-Country Analysis
  • 2019
  • Ingår i: Jacc-Heart Failure. - : Elsevier BV. - 2213-1779. ; 7:4, s. 336-346
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES This study examined the relationship between income inequality and heart failure outcomes. BACKGROUND The income inequality hypothesis postulates that population health is influenced by income distribution within a society, with greater inequality associated with worse outcomes. METHODS This study analyzed heart failure outcomes in 2 large trials conducted in 54 countries. Countries were divided by tertiles of Gini coefficients (where 0% represented absolute income equality and 100% represented absolute income inequality), and heart failure outcomes were adjusted for standard prognostic variables, country per capita income, education index, hospital bed density, and health worker density. RESULTS Of the 15,126 patients studied, 5,320 patients lived in Gini coefficient tertile 1 countries (coefficient: <33%), 6,124 patients lived in tertile 2 countries (33% to 41%), and 3,772 patients lived in tertile 3 countries (>41%). Patients in tertile 3 were younger than tertile 1 patients, were more often women, and had less comorbidity and several indicators of less severe heart failure, yet the tertile 3-to-1 hazard ratios (HRs) for the primary composite outcome of cardiovascular death or heart failure hospitalization were 1.57 (95% confidence interval [CI]: 1.38 to 1.79) and 1.48 for all-cause death (95% CI: 1.29 to 1.71) after adjustment for recognized prognostic variables. After additional adjustments were made for per capita income, education index, hospital bed density, and health worker density, these HRs were 1.46 (95% CI: 1.25 to 1.70) and 1.30 (95% CI: 1.10 to 1.53), respectively. CONCLUSIONS Greater income inequality was associated with worse heart failure outcomes, with an impact similar to those of major comorbidities. Better understanding of the societal and personal bases of these findings may suggest approaches to improve heart failure outcomes. (C) 2019 The Authors.

  • The prevalence and importance of frailty in heart failure with reduced ejection fraction - an analysis of PARADIGM-HF and ATMOSPHERE
  • 2020
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 22:11, s. 2123-2133
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims Frailty, characterized by loss of homeostatic reserves and increased vulnerability to physiological decompensation, results from an aggregation of insults across multiple organ systems. Frailty can be quantified by counting the number of 'health deficits' across a range of domains. We assessed the frequency of, and outcomes related to, frailty in patients with heart failure and reduced ejection fraction (HFrEF). Methods and results Using a cumulative deficits approach, we constructed a 42-item frailty index (FI) and applied it to identify frail patients enrolled in two HFrEF trials (PARADIGM-HF and ATMOSPHERE). In keeping with previous studies, patients with FI <= 0.210 were classified as non-frail and those with higher scores were divided into two categories using score increments of 0.100. Clinical outcomes were examined, adjusting for prognostic variables. Among 13 625 participants, mean (+/- standard deviation) FI was 0.250 (0.10) and 8383 patients (63%) were frail (FI >0.210). The frailest patients were older and had more symptoms and signs of heart failure. Women were frailer than men. All outcomes were worse in the frailest, with high rates of all-cause death or all-cause hospitalization: 40.7 (39.1-42.4) vs. 22.1 (21.2-23.0) per 100 person-years in the non-frail; adjusted hazard ratio 1.63 (1.53-1.75) (P < 0.001). The rate of all-cause hospitalizations, taking account of recurrences, was 61.5 (59.8-63.1) vs. 31.2 (30.3-32.2) per 100 person-years (incidence rate ratio 1.76; 1.62-1.90; P < 0.001). Conclusion Frailty is highly prevalent in HFrEF and associated with greater deterioration in quality of life and higher risk of hospitalization and death. Strategies to prevent and treat frailty are needed in HFrEF.

  • Natriuretic peptide plasma concentrations and risk of cardiovascular versus non-cardiovascular events in heart failure with reduced ejection fraction: Insights from the PARADIGM-HF and ATMOSPHERE trials
  • 2021
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703. ; 237, s. 45-53
  • Tidskriftsartikel (refereegranskat)abstract
    • Background : N-terminal pro-B-type natriuretic peptide (NT-proBNP) plasma concentrations are independent prognostic markers in patients with heart failure and reduced ejection fraction (HFrEF). Whether a differential risk association between NT-proBNP plasma concentrations and risk of cardiovascular (CV) vs non-CV adverse events exists is not well known. Objective : To assess if there is a differential proportional risk of CV vs non-CV adverse events by NT-proBNP plasma concentrations. Methods : In this post hoc combined analysis of PARADIGM-HF and ATMOSPHERE trials, proportion of CV vs non-CV mortality and hospitalizations were assessed by NT-proBNP levels ( <400, 400-999, 1000-1999, 2000-2999, and >3000 pg/mL) at baseline using Cox regression adjusting for traditional risk factors. Results : A total of 14,737 patients with mean age of 62 +/- 8 years (24% history of atrial fibrillation [AF]) were studied. For CV deaths, the event rates per 1000 patient-years steeply increased from 33.8 in the <= 400 pg/mL group to 142.3 in the >= 3000 pg/mL group, while the non-CV death event rates modestly increased from 9.0 to 22.7, respectively. Proportion of non-CV deaths decreased across the 5 NT-proBNP groups (21.1%, 18.4%, 17.9%, 17.4%, and 13.7% respectively). Similar trend was observed for non-CV hospitalizations (46.4%, 42.6%, 42.9%, 42.0%, and 36.9% respectively). These results remained similar when stratified according to the presence of AF at baseline and prior HF hospitalization within last 12 months. Conclusions : The absolute CV event rates per patient years of follow-up were greater and had higher stepwise increases than non-CV event rates across a broad range of NT-proBNP plasma concentrations indicating a differential risk of CV events at varying baseline NT-proBNP values. These results have implications for future design of clinical trials.

  • Predicting stroke in heart failure and reduced ejection fraction without atrial fibrillation
  • 2022
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 43:42
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims Patients with heart failure with reduced ejection fraction (HFrEF) are at significant risk of stroke. Anticoagulation reduces this risk in patients with and without atrial fibrillation (AF), but the risk-to-benefit balance in the latter group, overall, is not favourable. Identification of patients with HFrEF, without AF, at the highest risk of stroke may allow targeted and safer use of prophylactic anticoagulant therapy. Methods and results In a pooled patient-level cohort of the PARADIGM-HF, ATMOSPHERE, and DAPA-HF trials, a previously derived simple risk model for stroke, consisting of three variables (history of prior stroke, insulin-treated diabetes, and plasma N-terminal pro-B-type natriuretic peptide level), was validated. Of the 20 159 patients included, 12 751 patients did not have AF at baseline. Among patients without AF, 346 (2.7%) experienced a stroke over a median follow up of 2.0 years (rate 11.7 per 1000 patient-years). The risk for stroke increased with increasing risk score: fourth quintile hazard ratio (HR) 2.35 [95% confidence interval (CI) 1.60-3.45]; fifth quintile HR 3.73 (95% CI 2.58-5.38), with the first quintile as reference. For patients in the top quintile, the rate of stroke was 21.2 per 1000 patient-years, similar to participants with AF not receiving anticoagulation (20.1 per 1000 patient-years). Model discrimination was good with a C-index of 0.84 (0.75-0.91). Conclusion It is possible to identify a subset of HFrEF patients without AF with a stroke-risk equivalent to that of patients with AF who are not anticoagulated. In these patients, the risk-to-benefit balance might justify the use of prophylactic anticoagulation, but this hypothesis needs to be tested prospectively.

  • Prognostic Value of N-Terminal Pro-B-Type Natriuretic Peptide Levels in Heart Failure Patients With and Without Atrial Fibrillation
  • 2017
  • Ingår i: Circulation Heart Failure. - 1941-3289 .- 1941-3297. ; 10:10
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with heart failure (HF) and atrial fibrillation (AF) have higher circulating levels of NT-proBNP (N-terminal pro-B-type natriuretic peptide) than HF patients without AF. There is uncertainty about the prognostic importance of a given concentration of NT-proBNP in HF patients with and without AF. We investigated this question in a large cohort of patients with HF and reduced ejection fraction. METHODS AND RESULTS: We studied 14 737 patients with HF and reduced ejection fraction and a measurement of NT-proBNP at time of screening, enrolled in either the PARADIGM-HF trial (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) or the ATMOSPHERE trial (Aliskiren Trial to Minimize Outcomes in Patients With Heart Failure), of whom 3575 (24%) had AF on their baseline ECG. Median (Q1, Q3) levels of NT-proBNP were 1817 pg/mL (1095-3266 pg/mL) in those with AF and 1271 pg/mL (703-2569 pg/mL) in those without (P<0.0001). Patients with AF were older (67 versus 62 years), had worse New York Heart Association class (III/IV; 36% versus 24%), and experienced fewer previous HF hospitalizations (52% versus 61%) or myocardial infarction (30% versus 46%); all P<0.001. We categorized patients with and without AF into 5 NT-proBNP bands: <400, 400 to 999 (reference), 1000 to 1999, 2000 to 2999, and >/=3000 pg/mL. For the primary composite outcome of cardiovascular death or HF hospitalization, event rates differed for patients with and without AF in the lowest band (<400 pg/mL; 8.2 versus 5.0 per 100 patient-years), but not for the higher bands (400-999 pg/mL, 7.4 versus 7.7 per 100 patient-years; 1000-1999 pg/mL, 9.8 versus 11.4 per 100 patient-year; 2000-2999 pg/mL, 13.5 versus 13.4 per 100 patient-years; >/=3000 pg/mL, 22.7 versus 23.0 per 100 patient-years). These findings were consistent whether NT-proBNP was examined as a categorical or continuous variable and before and after adjustment for other prognostic variables. We found similar results for the components of the composite outcome and all-cause mortality. CONCLUSIONS: HF and reduced ejection fraction patients with AF had higher NT-proBNP than those without AF. However, above a concentration of 400 pg/mL (representing most patients in each group), NT-proBNP had similar predictive value for adverse cardiovascular outcomes, irrespective of AF status.

  • Type of Atrial Fibrillation and Outcomes in Patients With Heart Failure and Reduced Ejection Fraction
  • 2017
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier BV. - 0735-1097 .- 1558-3597. ; 70:20, s. 2490-2500
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Atrial fibrillation (AF) is common in heart failure (HF), but the outcome by type of AF is largely unknown. OBJECTIVES: This study investigated outcomes related to type of AF (paroxysmal, persistent or permanent, or new onset) in 2 recent large trials in patients with HF with reduced ejection fraction. METHODS: The study analyzed patients in the PARADIGM-HF (Prospective comparison of ARNI with ACEI to Determine Impact on Global Mortality and morbidity in Heart Failure) and ATMOSPHERE (Aliskiren Trial to Minimize Outcomes in Patients with Heart Failure) trials. Multivariable Cox regression models were used to estimate hazard ratios (HRs) for outcomes related to AF type. RESULTS: Of 15,415 patients, 5,481 (35.6%) had a history of AF at randomization, and of these, 1,645 (30.0%) had paroxysmal AF. Compared with patients without AF, patients with paroxysmal AF at randomization had a higher risk of the primary composite endpoint of cardiovascular death or HF hospitalization (HR: 1.20; 95% confidence interval [CI]: 1.09 to 1.32; p < 0.001), HF hospitalization (HR: 1.34; 95% CI: 1.19 to 1.51; p < 0.001), and stroke (HR: 1.34; 95% CI: 1.02 to 1.76; p = 0.037), whereas the corresponding risks in patients with persistent or permanent AF were not elevated. Neither type of AF was associated with higher mortality. New onset AF was associated with the greatest risk of adverse outcomes: primary endpoint (HR: 2.21; 95% CI: 1.80 to 2.71), HF hospitalization (HR: 2.11; 95% CI: 1.58 to 2.81), stroke (HR: 2.20; 95% CI: 1.25 to 3.88), and all-cause mortality (HR: 2.26; 95% CI: 1.86 to 2.74), all p values < 0.001, compared with patients without AF. Anticoagulants were used less often in patients with paroxysmal (53%) and new onset (16%) AF than in patients with persistent or permanent AF (71%). CONCLUSIONS: Among HF patients with a history of AF, those with paroxysmal AF were at greater risk of HF hospitalization and stroke than were patients with persistent or permanent AF, underlining the importance of anticoagulant therapy. New onset AF was associated with increased risk of all outcomes.
