ABSTRACT: Aims
Heart failure (HF) is a leading cause of hospitalization and is associated with high morbidity and mortality. We examined the impact of recurrent HF hospitalizations (HFHs) on cardiovascular (CV) mortality among patients with HF in Sweden.Methods and results
Adults with incident HF were identified from linked national health registers and electronic medical records from 01 January 2005 to 31 December 2013 for Uppsala and until 31 December 2014 for Västerbotten. CV mortality and all-cause mortality were evaluated. A time-dependent Cox regression model was used to estimate relative CV mortality rates for recurrent HFHs. Assessment was also done for ejection fraction-based HF phenotypes and for comorbid atrial fibrillation, diabetes, or chronic renal impairment. Overall, 3878 patients with HF having an index hospitalization were included, providing 9691.9 patient-years of follow-up. Patients were relatively old (median age: 80 years) and were more frequently male (55.5%). Compared with patients without recurrent HFHs, the adjusted hazard ratio (HR [95% confidence interval; CI]) for CV mortality and all-cause mortality were statistically significant for patients with one, two, three, and four or more recurrent HFHs. The risk of CV mortality and all-cause mortality increased approximately six-fold in patients with four or more recurrent HFHs vs. those without any HFHs (HR [95% CI]: 6.26 [5.24-7.48] and 5.59 [4.70-6.64], respectively). Similar patterns were observed across the HF phenotypes and patients with comorbidities.Conclusions
There is a strong association between recurrent HFHs and CV and all-cause mortality, with the risk increasing progressively with each recurrent HFH.

Project description:BACKGROUND:Despite advances in pharmacologic therapy and devices, patients with heart failure (HF) continue to have significant rehospitalization rates and risk prediction remains challenging. We sought to explore the value of a multi-biomarker panel [including NT-proBNP, high-sensitivity cardiac troponin T (hs-TnT), and ST2] on top of clinical assessment for long-term prediction of recurrent hospitalizations in HF. METHODS AND RESULTS:NT-proBNP, hs-TnT, and ST2 (suppression of tumorigenicity-2) levels were measured in 891 consecutive ambulatory HF patients. The independent association between the multi-biomarker panel and recurrent hospitalizations was assessed through a multivariable negative binomial regression and expressed as incidence rates ratios. McFadden pseudo-R2 and goodness-of-fit measures were also used. The total number of unplanned hospitalizations [all-cause, cardiovascular (CV)-, and HF-related] were selected as the primary endpoints. At a mean follow-up of 4.2?±?2.1?years, 1623 all-cause hospitalizations in 498 patients (55.9%), 710 CV-related hospitalizations in 331 patients (37.2%), and 444 HF-related hospitalizations in 214 patients (24.1%) were registered. The crude incidence of all-cause, CV-, and HF-related recurrent hospitalizations was significantly higher for patients with the multi-biomarker panel above the cut-point (hs-TnT?>?14?ng/L, NT-proBNP?>?1000?ng/L, and ST2?>?35?ng/mL) (all P?<?0.001). For all-cause, CV-, and HF-related recurrent hospitalizations, the McFadden R2, Akaike information criterion, and Bayesian information criterion supported the superiority of incorporating the multi-biomarker panel into a clinical predictive model. CONCLUSION:A multi-biomarker approach based on NT-proBNP, hs-TnT, and ST2 better identifies HF patients at risk for recurrent hospitalizations as compared to approaches entailing just one or two of these biomarkers. Elucidation of new biophysiological predictors for recurrent hospitalizations may identify patient profiles for focused intervention.

Project description:Study objectivesSleep apnea is prevalent in patients undergoing coronary artery bypass grafting (CABG). We investigated the relationship between sleep apnea and recurrent heart failure hospitalizations in patients undergoing nonurgent CABG.MethodsBetween November 2013 and December 2018, 1,007 patients completed a sleep study prior to CABG and were followed up until April 2020. Recurrent heart failure hospitalizations were analyzed by Poisson, negative binomial, Andersen-Gill, and joint frailty models, with partial and full adjustment for covariates.ResultsAt an average follow-up of 3.3 years, the number of patients with 0, 1, or ≥ 2 heart failure hospitalizations were 908 (90.2%), 62 (6.2%), and 37 (3.7%), respectively. The total number of heart failure hospitalizations was 179, comprising 62 (35%) first and 117 (65%) repeat events. The numbers of heart failure hospitalizations for the sleep apnea (n = 513, 50.9%) and nonsleep apnea groups were 127 and 52, respectively. Negative binomial regression demonstrated that sleep apnea was associated with recurrent heart failure hospitalizations (fully adjusted rate ratio, 1.71; 95% confidence interval [CI], 1.12-2.62; P = .013). Similar results were found in Poisson (1.63; 95% CI, 1.15-2.31; P = .006), Andersen-Gill (1.66; 95% CI, 1.01-2.75; P = .047), and joint frailty models (1.72; 95% CI, 1.00-3.01; P = .056).ConclusionsIn patients after CABG, repeat events accounted for two-thirds of heart failure hospitalizations. Sleep apnea was independently associated with recurrent heart failure hospitalizations.CitationTeo YH, Tam WT, Koo C-Y, et al.

Project description:BackgroundPatients with heart failure (HF) and reduced ejection fraction will experience multiple hospitalizations for heart failure during the course of their disease. We assessed the efficacy of dapagliflozin on reducing the rate of total (ie, first and repeat) hospitalizations for heart failure in the DAPA-HF trial (Dapagliflozin and Prevention of Adverse-Outcomes in Heart Failure).MethodsThe total number of HF hospitalizations and cardiovascular deaths was examined by using the proportional-rates approach of Lei-Wei-Yang-Ying and a joint frailty model for each of recurrent HF hospitalizations and time to cardiovascular death. Variables associated with the risk of recurrent hospitalizations were explored in a multivariable Lei-Wei-Yang-Ying model.ResultsOf 2371 participants randomly assigned to placebo, 318 experienced 469 hospitalizations for HF; of 2373 assigned to dapagliflozin, 230 patients experienced 340 admissions. In a multivariable model, factors associated with a higher risk of recurrent HF hospitalizations included higher heart rate, higher N-terminal pro-B-type natriuretic peptide, and New York Heart Association class. In the Lei-Wei-Yang-Ying model, the rate ratio for the effect of dapagliflozin on recurrent HF hospitalizations or cardiovascular death was 0.75 (95% CI, 0.65-0.88), P=0.0002. In the joint frailty model, the rate ratio for total HF hospitalizations was 0.71 (95% CI, 0.61-0.82), P<0.0001, whereas, for cardiovascular death, the hazard ratio was 0.81 (95% CI, 0.67-0.98), P=0.0282.ConclusionsDapagliflozin reduced the risk of total (first and repeat) HF hospitalizations and cardiovascular death. Time-to-first event analysis underestimated the benefit of dapagliflozin in HF and reduced ejection fraction. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03036124.

Project description:AimsWe aim to report trends in unplanned hospitalizations among newly diagnosed heart failure patients with regard to hospitalizations types and their impact on outcomes.Methods and resultsA nation-wide study of all citizens in Poland with newly diagnosed heart failure based on ICD-10 coding who were beneficiaries of either public primary, secondary, or hospital care between 2013 and 2018 in Poland. Between 1 January 2013 and 31 December 2019, there were 1 124 118 newly diagnosed heart failure patients in Poland in both out- and inpatient settings. The median observation time was 946 days. As many as 49% experienced at least one acute heart failure hospitalization. Once hospitalized, 44.6% patients experienced at least one all-cause rehospitalization and 26% another heart failure rehospitalization. The latter had the highest Charlson co-morbidity index (1.36). The 30 day heart failure readmission rate was 2.96%. Kaplan-Meier analysis revealed very early readmissions (up to 1-7 days) were associated with better survival compared with rehospitalization between 8 and 30 days. All-cause mortality was related to the number of hospitalization with adjusted estimated hazard ratios: 1.550 (95% CI: 1.52-158) for the second HF hospitalization, 2.158 (95% CI: 2.098-2.219) for third, and 2.788 (95% CI: 2.67-2.91) for the fourth HF hospitalization and subsequent ones, as compared with the first hospitalization.ConclusionsAmong newly diagnosed heart failure patients in Poland between 2013 and 2019, nearly half required at least one unplanned heart failure hospitalization. The risk of death was growing with every other hospital reoccurrence due to heart failure.

Project description:AimsAlthough diabetes mellitus (DM) is a common co-morbidity in chronic heart failure (HF) patients, European data on concurrent HF and DM treatment are lacking. Therefore, we have studied the HF treatment of patients with and without DM. Additionally, with the recent breakthrough of sodium-glucose cotransporter 2 (SGLT2) inhibitors in the field of HF, we studied the potential impact of this new drug in a large cohort of HF patients.Methods and resultsA total of 7488 patients with chronic HF with a left ventricular ejection fraction <50% from 34 Dutch outpatient HF clinics between 2013 and 2016 were analysed on diabetic status and background HF therapy. Average age of the total population was 72.8 years (±11.7 years), and 64% of the patients were male. Diabetes was present in 29% of the patients (N = 2174). Diabetics had a worse renal function (mean estimated glomerular filtration rate 56 vs. 61 mL/min/1.73 m2 , P < 0.001). Renin-angiotensin system inhibitors were less often prescribed in diabetics compared with non-diabetics (79% vs. 82%, P = 0.001), while no significant differences regarding other guideline-recommended HF drugs were found. Target doses of beta-blockers (23% vs. 16%, P < 0.001), renin-angiotensin system inhibitors (47% vs. 43%, P = 0.009), and mineralocorticoid receptor antagonists (57% vs. 51%, P = 0.005) were more often prescribed in diabetics than non-diabetics. Based on the latest trials on SGLT2 inhibitors, 31-64% of all HF patients would fulfil the eligibility or enrichment criteria (with vs. without N-terminal prohormone BNP criterion).ConclusionsIn this large real-world HF registry, a high prevalence of DM was observed and diabetics more often received guideline-recommended target doses. Based on current evidence, the majority of patients would fulfil the enrichment criteria of SGLT2 trials in HF and the impact of this new drug class will be large.

Project description:PURPOSE:PARADIGM-HF demonstrated the superiority of sacubitril/valsartan over enalapril in patients with heart failure and reduced ejection fraction (HF-REF). How widely applicable sacubitril/valsartan treatment is in unselected patients with HF-REF is not known. We examined eligibility of patients with HF-REF for treatment with sacubitril/valsartan, according to the criteria used in PARADIGM-HF, in the Swedish Heart Failure Registry (SwedeHF). METHODS:Patients were considered potentially eligible if they were not hospitalized, had symptoms (NYHA class II-IV) and a reduced LVEF (≤ 40%), and were prescribed an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) at a dose equivalent to enalapril ≥ 10 mg daily. In these patients, we evaluated further eligibility according to the main additional PARADIGM-HF inclusion criteria. RESULTS:Of 12,866 outpatients in NYHA functional class II-IV with an LVEF ≤ 40%, 9577 were prescribed at least 10 mg of enalapril (or equivalent) daily. Complete additional data were available for 3099 of these patients (32.4%) and of them 75.5% were potentially eligible for treatment with sacubitril/valsartan. The most common reason for ineligibility was a low natriuretic peptide level (n = 462, 14.9%). Only a small proportion of patients were ineligible due to low eGFR or serum potassium level. Because only 78% of patients were taking ≥ 10 mg enalapril or equivalent daily, only 58.9% of all patients (75.5% of 78%) were eligible for sacubitril/valsartan. CONCLUSIONS:Between 34 and 76% of symptomatic patients with HF-REF in a 'real world' population are eligible for treatment with sacubitril/valsartan, depending on background ACEI/ARB dose. The most common reason for ineligibility is a low natriuretic peptide level.

Project description:BackgroundSodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the composite of heart failure (HF) hospitalizations or cardiovascular mortality among patients with HF. However, the efficacy of SGLT2 inhibitors in secondary endpoints of randomized trials and in subgroups of HF patients is not well known.MethodsWe performed a systematic review and meta-analysis of placebo-controlled, randomized trials of SGLT2 inhibitors in patients with HF. PubMed, Embase, and Cochrane databases were searched for trials published up to January 21, 2021. Data were extracted from published reports and quality assessment was performed per Cochrane recommendations. Hazard ratios (HRs) with 95% CI were pooled across trials. The primary endpoints of interest were all-cause and cardiovascular mortality.ResultsOut of 3969 database results, 15 randomized trials and 20,241 patients were included; 10,594 (52·3%) received SGLT2 inhibitors. All-cause mortality (HR 0·86; 95% CI 0·79-0·94; p = 0·0007; I2=0%) and cardiovascular mortality (HR 0·86; 95% CI 0·78-0·96; p = 0·006; I2=0%) were significantly lower in patients treated with SGLT2 inhibitors compared with placebo. The composite of cardiovascular mortality, HF hospitalizations, or urgent visits for HF was significantly reduced with SGLT2 inhibitors in all the following subgroups: male, female, age < 65, age ≥ 65, race - Black and White, estimated glomerular filtration rate (eGFR) <60, eGFR ≥60, New York Heart Association (NYHA) class II, NYHA ≥III, and HF with preserved ejection fraction.InterpretationIn patients with HF, SGLT2 inhibitors significantly reduce all-cause and cardiovascular mortality compared with placebo. In addition, the composite of cardiovascular mortality or HF hospitalizations/urgent visits is reduced with SGLT2 inhibitors across subgroups of sex, age, race, eGFR, HF functional class, and ejection fraction.

Project description:Food deserts (FD), low-income areas with low access to healthful foods, are associated with higher burden of cardiovascular risk factors. Few studies have examined the impact of FD on clinical outcomes in heart failure (HF). FD status was assessed in 457 HF patients (mean age 55.9 ± 12.5 years; 50.3% Black) using the Food Desert Research Atlas. The Andersen-Gill extension of Cox model was used to examine the association of living in a FD with risk of repeat hospitalization (all-cause and HF-specific). Patients living in a FD were younger (p = 0.01), more likely to be Black (p <0.0001), less educated (p = 0.003), and less likely to have commercial insurance (p = 0.003). During a median follow-up of 827 (506, 1,379) days, death occurred in 60 (13.1%) subjects, and hospitalizations occurred in 262 (57.3%) subjects. There was no difference in the risk of death based on FD status. The overall frequency of all-cause (94.1 vs 63.6 per 100 patient-years) and HF-specific (59.6 vs 30.5 per 100 patient-years) hospitalizations was higher in subjects who lived in a FD. After adjustment for covariates, living in a FD was associated with an increased risk of repeat all-cause (hazard ratio 1.39, 95% confidence interval 1.19 to 1.63; p = 0.03) and HF-specific (hazard ratio 1.30, 95% confidence interval 1.02 to 1.65; p = 0.03) hospitalizations. In conclusion, patients living in a FD have a higher risk of repeat all-cause and HF-specific hospitalization.

Project description:AimsThe proportion of patients hospitalized for heart failure (HF) with preserved left ventricular ejection fraction (LVEF) is rising, but no approved treatment exists, in part owing to incomplete characterization of this particular HF phenotype. In order to better define the characteristics of HF phenotypes in Finland, a large cohort with 12 years' follow-up time was analysed.Methods and resultsPatients diagnosed between 2005 and 2017 at the Hospital District of Southwest Finland were stratified according to LVEF measure and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels. For this retrospective registry study, previously diagnosed HF patients were defined as follows: patients with reduced ejection fraction (HFrEF; LVEF ≤ 40%; n = 4042), mid-range ejection fraction (HFmrEF; LVEF > 40-50% and NT-proBNP ≥ 125 pg/mL; n = 1468), and preserved ejection fraction (HFpEF; LVEF > 50% and NT-proBNP ≥ 125 pg/mL; n = 3122) and followed up for 15 022, 4962, and 10 097 patient-years, respectively. Cardiovascular (CV) hospitalization and mortality, influence of pre-selected covariates on hospitalization and mortality, and the proportion of HFpEF and HFmrEF patients with a drop in LVEF to HFrEF phenotype were analysed. All data were extracted from the electronic patient register. HFrEF patients were rehospitalized slightly earlier than HFpEF/HFmrEF patients, but the second, third, and fourth rehospitalization rates did not differ between the subgroups. Female gender and better kidney function were associated with reduced rehospitalizations in HFmrEF and HFrEF, with a non-significant trend in HFpEF. Each additional hospitalization was associated with a two-fold increased risk of death and 2.2- to 2.3-fold increased risk of CV death. All-cause mortality was higher in patients with HFpEF. Although CV mortality was less frequent in HFpEF patients, it was associated with increased NT-proBNP concentrations at index in all patient groups. During the 10 years following the index date, 26% of HFmrEF patients and 10% of HFpEF patients progressed to an HFrEF phenotype.ConclusionsThese findings suggest that disease progression, in terms of increased frequency of hospitalizations, and the relationship between increased number of hospitalizations and mortality are similar by LVEF phenotypes. These data highlight the importance of effective treatments that can reduce hospitalizations and suggest a role for monitoring NT-proBNP levels in the management of HFpEF patients in particular.

Project description:AimsIn Portugal, in the last 5 years, no study has published recent data regarding outcomes of patients with acute decompensated heart failure (ADHF). We aimed to determine the characteristics and outcomes of a large contemporaneous Portuguese cohort of ADHF patients admitted to our emergency department (ED).Methods and resultsWe conducted a retrospective, study of all 1024 patients admitted to our ED with a discharge diagnosis of ADHF from November 2016 to December 2017. Baseline clinical data and outcomes {in-hospital, 30 day, and follow-up all-cause mortality, and readmissions; median follow-up, 5 months; interquartile range [(IQR), 3-11 months]} were determined. Mean age was 78 ± 10 years, and 53% were male; of the 1024 patients, 554 (54%) were hospitalized. The median hospitalization length was 9 (IQR, 5-15) days, and in-hospital mortality was 12.7%. Hospitalized patients were predominantly men (56% vs. 47%; P < 0.001), younger (77 ± 9 vs. 79 ± 11 years; P = 0.002) and had higher creatinine values and B-type natriuretic peptide values (P < 0.001) than discharged patients. Patients with prior hospitalization had lower 30 day readmission rate (8% vs. 14%; P = 0.01), same overall readmission rate (30% vs. 32%), and higher 30 day (13% vs. 5%; P < 0.001) and overall mortality rates (28% vs. 15%; P < 0.001).ConclusionsApproximately half of the patients admitted to the ED were hospitalized. Of these, only 8% were readmitted in the ED within 30 days. The clinical and analytical status in the ED are important predictors of hospitalization.
