Temporal trends, sex-differences and outcomes of patients hospitalized for heart failure in Germany

Abstract Background Despite remarkable improvements in treatment of cardiovascular disease, heart failure (HF) is still characterized by a high mortality rate. Sex-specific differences in HF have been described, but underlying reasons are widely unexplored. Thus, we aimed to investigate sex differences of patients hospitalized for HF in a nationwide cohort. Methods The nationwide German inpatient sample (2005–2016) was used for this sex-specific analyses. Temporal trends on hospitalizations, mortality, and treatments were analyzed and independent predictors of adverse outcomes identified. Results The present analysis comprises 4,538,977 hospitalizations due to HF (52.0%women) in Germany (2005–2016). Although women were older (median 82 (IQR75–87) vs. 76 (69–82), P<0.001), coronary artery disease (CAD, 50.3% vs. 30.7%, P<0.001) was more prevalent in men, who were more often treated with PCI (3.4% vs. 1.4%, P<0.001) and implantable cardioverter-defibrillator (2.2% vs. 0.5%, P<0.001). In-hospital mortality was significantly lower in men than in women (8.9% vs. 10.2, P=0.001) and was reduced in patients who received PCI or implantation of an ICD. While total numbers of hospitalizations between 2005 and 2016 increased in both men (β-estimate 7185.71 (95% CI 6502.23 to 7869.18), P<0.001) and women (β-estimate 5297.60 (95% CI 4557.37 to 6037.83), P<0.001) as well as almost all comorbid co-conditions, in-hospital mortality rate decreased more distinctly in women (β-estimate −0.41 (95% CI: −0.42 to −0.39), P<0.001) compared to men (β-estimate −0.29 (95% CI: −0.30 to −0.27), P<0.001). Conclusions Interventional treatments of HF were associated with improved outcomes and equally beneficial for both sexes. However, they were more often used in male HF patients, in which CAD is significantly more frequent than in female HF patients. This may explain the higher case fatality rate of HF in females.

Introduction: Recent studies have shown catheter ablation for atrial fibrillation (AF) in patients with heart failure (HF) to have better outcomes over medical therapy. While AF ablation is predominantly an outpatient procedure, some patients may require longer hospitalization. Limited literature exists describing the trends of hospitalizations for HF patients undergoing AF ablation. Methods: Using ICD-9 (diagnosis and procedure codes) in nationwide inpatient sample database 2003 to 2014, we identified all HF adults who were admitted with a principal diagnosis code of AF (427.31) (n= 4,670,400) (AF-HF). Among these, we identified those with a principal procedure code of catheter ablation (37.34) and studied the temporal trends of clinical characteristics and outcomes (in-hospital mortality and complications) for this cohort (Table). Results: The overall number of AF-HF patients undergoing AF ablation was 62,653; with an increase from 1,928 in 2003 to 6,860 in 2014 (p trend<0.001). As shown in Table, over this 12-year period; mean age and proportion of females decreased, while there was an increase in blacks, clinical comorbidity burden, admissions to teaching hospitals and southern US region (all p trend<0.001). The overall procedure related complications (vascular, cardiac, respiratory, neurologic) increased, the in-hospital mortality rate decreased from 1.7% to 0.5% (all p trend<0.001). Conclusions: During 2003-2014, the annual incidence of AF ablation related hospitalizations in HF patients increased significantly. Despite increase in clinical comorbidities burden and procedural complication rates, the mortality rate declined.

Generalised Linear Mixed Model

ObjectiveAtrial fibrillation or atrial flutter (AF) and heart failure (HF) often go hand in hand and, in combination, lead to an increased risk of death compared with patients with just one of both entities. Sex-specific differences in patients with AF and HF are under-reported. Therefore, the aim of this study was to investigate sex-specific catheter ablation (CA) use and acute in-hospital outcomes in patients with AF and concomitant HF in a retrospective cohort study.MethodsUsing International Statistical Classification of Diseases and Related Health Problems and Operations and Procedures codes, administrative data of 75 hospitals from 2010 to 2018 were analysed to identify cases with AF and HF. Sex differences were compared for baseline characteristics, right and left atrial CA use, procedure-related adverse outcomes and in-hospital mortality.ResultsOf 54 645 analysed cases with AF and HF, 46.2% were women. Women were significantly older (75.4±9.5 vs 68.7±11.1 years, p<0.001), had different comorbidities (more frequently: cerebrovascular disease (2.4% vs 1.8%, p<0.001), dementia (5.3% vs 2.2%, p<0.001), rheumatic disease (2.1% vs 0.8%, p<0.001), diabetes with chronic complications (9.7% vs 9.1%, p=0.033), hemiplegia or paraplegia (1.7% vs 1.2%, p<0.001) and chronic kidney disease (43.7% vs 33.5%, p<0.001); less frequently: myocardial infarction (5.4% vs 10.5%, p<0.001), peripheral vascular disease (6.9% vs 11.3%, p<0.001), mild liver disease (2.0% vs 2.3%, p=0.003) or any malignancy (1.0% vs 1.3%, p<0.001), underwent less often CA (12.0% vs 20.7%, p<0.001), had longer hospitalisations (6.6±5.8 vs 5.2±5.2 days, p<0.001) and higher in-hospital mortality (1.6% vs 0.9%, p<0.001). However, in the multivariable generalised linear mixed model for in-hospital mortality, sex did not remain an independent predictor (OR 0.96, 95% CI 0.82 to 1.12, p=0.579) when adjusted for age and comorbidities. Vascular access complications requiring interventions (4.8% vs 4.2%, p=0.001) and cardiac tamponade (0.3% vs 0.1%, p<0.001) occurred more frequently in women, whereas stroke (0.6% vs 0.5%, p=0.179) and death (0.3% vs 0.1%, p=0.101) showed no sex difference in patients undergoing CA.ConclusionsThere are sex differences in patients with AF and HF with respect to demographics, resource utilisation and in-hospital outcomes. This needs to be considered when treating women with AF and HF, especially for a sufficient patient informed decision making in clinical practice.

Abstract Sirtuin 4 (SIRT4) is a mitochondrial NAD+-dependent deacylase which inhibits the oxidation of glucose and fatty acids, and has been implicated in the regulation of oxidative stress. Given the importance of cardiac energy depletion and ROS during heart failure development, we aimed to define the role of SIRT4 in the development of heart failure. Mice with deletion (SIRT4−/−) or overexpression (SIRT4 TG) of SIRT4 were subjected to transverse aortic constriction (TAC) for 12 weeks or underwent sham procedures. Using echocardiography, ejection fraction (EF) was not different between SIRT4 TG and WT mice subjected to sham operations. In contrast, TAC induced a more pronounced decrease in EF (35% vs. 51%; p<0.05), and a more pronounced increase in LV endsystolic diameter (4.5mm vs. 3.6mm; p<0.05) and myocardial fibrosis (2.2-fold; p<0.05) in SIRT4 TG mice compared to WT mice. Myocardial levels of the lipid peroxidation product 4-hydroxynonenal were increased in WT mice following TAC and were synergistically increased in SIRT4 TG mice following TAC (+66% vs. WT TAC; p<0.05). Administration of the mitochondria-targeted antioxidant MitoQ normalized 4-hydroxynonenal levels, markedly attenuated the decline in EF and almost normalized endsystolic LV diameter in SIRT4 TG mice following TAC. Cardiac function and morphology were unaffected in SIRT4−/− mice during normal or increased workload conditions. Thus, while SIRT4 is not required to maintain cardiac function even in response to increased energy demands, increased expression of SIRT4 accelerates the development of heart failure following TAC, at least in part due to increased mitochondrial oxidative stress.

Abstract Background Heart failure (HF) is a leading cause of morbidity and mortality worldwide. Measurement of BNP and NTproBNP are used in HF for diagnosis and prognosis but levels of these peptides are inappropriately low in obesity, a condition which is associated with increased HF. Cleavage of proBNP to produce BNP and NT-proBNP requires proBNP to be unglycosylated at threonine 71 (T71). Gycosylation at T71 is affected by obesity, resulting in lower plasma NT-proBNP concentrations in patients with higher BMI. However the relationships between BMI, proBNP glycosylation and BNP (particularly the bioactive cardio-protective peptide BNP1-32) have not previously been described. Methods Validated in-house assays for BNP, BNP1-32, proBNP, proBNP unglycosylated at T71 (NG-T71) and the commercial Roche assay for NT-proBNP were applied to plasma samples obtained from patients with HF (n=321, PEOPLE study: Prospective Evaluation of Outcome in Patients with Left Ventricular Ejection Fraction). Results Median (IQR) concentrations of BNP, BNP1-32, proBNP, NG-T71 and NTproBNP were 10.7 (5–21), 5 (2–9), 27.8 (9–62), 6.2 (3–22) and 217 (104–425) pmol/L respectively. BMI was inversely related to NG-T71, NT-proBNP, BNP and BNP1-32 (r=−0.19, −0.40, −0.36 and −0.34 respectively, all p<0.01) but not proBNP (r=0.11, ns). ProBNP levels in patients with BMI above or below 30 kg/m2 were similar (29.8 (11.2–56.6) and 22.5 (3.9–65) pmol/L, p=0.51), whereas NG-T71, NT-proBNP, BNP and BNP1-32 levels were increased (p<0.001) in patients with BMI <30 (11.6 (3–25.6), 263 (153–486), 13.8 (6.5–25.5) and 6.3 (2.8–10.4)) compared to BMI >30 (3 (1–16), 127 (63–274), 7.8 (3–14) and 3.6 (1.1–7) respectively. The BMI >30 group had increased ProBNP:NT-proBNP, ProBNP:BNP and ProBNP:BNP1-32 ratios (all p<0.001) and proBNP:NG-T71 (p=0.037), whereas ratios of NG-T71 to BNP, BNP1-32 or NT-proBNP were not related to BMI. Patients with diabetes (n=90) also had lower BNP, BNP1-32 (both p<0.01), NG-T71 and NT-proBNP concentrations (both p<0.05), but not proBNP (p=0.46), and a trend towards a higher proBNP:BNP1-32 ratio (p=0.06). Discussion and conclusion The negative association between BMI and plasma NT-proBNP and BNP is not well understood. We recently reported that obese patients with HF have reduced circulating levels of proBNP unglycosylated at T71. In this expanded sample we show that whilst proBNP remains unaffected by BMI, both immunoreactive BNP and more specifically bioactive BNP1–32 levels, and NT-proBNP, are decreased with obesity in conjunction with increased glycosylation at T71. Increased glycosylation at proBNP-T71 reduces the amount of proBNP cleaved to form NT-proBNP and BNP resulting in decreased production and lowered circulating concentrations of these clinically used marker peptides. Our results provide a robust mechanism to explain the reduction in NT-proBNP and BNP levels observed in obese patients and confirm this is associated with reduced bioactive BNP1–32.

Abstract Background Adherence to treatment guidelines in heart failure (HF) patients (pts) is of major prognostic importance, but thorough implementation of guidelines in routine care remains insufficient. Introducing hybrid comprehensive telerehabilitation (HCTR) consisting of telecare, telerehabilitation and remote monitoring of implantable devices might be an option to improve adherence to recommendation and can affect the prognosis. Purpose to investigate the association of adherence to HCTR with mortality and hospitalization. Methods The present analysis formed part of TELEREH-HF multicenter, randomized trial that enrolled 850 HF pts (NYHA I-III,LVEF≤40%). Patients were randomized 1:1 to HCTR plus usual care or usual care only and followed up for 14 to 26 months. During the first 9 weeks, pts underwent either an HCTR (1 week in hospital and 8 weeks at home) or usual care. This analysis focuses on pts randomized to HCTR. Adherent pts were those who adhered both to the number of training sessions prescribed and to the duration of the prescribed cycle by at least80%; non-adherent pts, were those who adhered<20% to the prescribed number of training sessions and their duration. The remaining pts were classified as partially adherent. Results There were 350 (88.4%) adherent pts, 39 (9.8%) partially adherent pts and 7 (1.8%) non-adherent pts. There were 54 deaths during follow-up in the HCTR arm. Non-adherence or partial adherence was associated with statistically significantly higher risk of cardiovascular (CV) mortality (hazard ratio (HR) = 2.62, p=0.021); all-cause mortality or HF hospitalization (HR=1.71, p=0.038); CV mortality or HF hospitalization (HR=1.89, p=0.014). Conclusion The adherence to HCTR was very high. Adherence to HCTR was associated with improved prognosis for CV mortality.

Abstract Introduction Risk for stroke and systemic embolism (SE) in patients with atrial fibrillation (AF) and heart failure (HF) with mid-range (mr) ejection fraction (EF) is not well known. Methods Total 10,780 patients (age, 66.8±11.1 years; men, 64.7%) with AF were included in a prospective, multicenter AF registry. The patients were grouped into four according to HF type: no-HF, HF with preserved EF (HFpEF), HFmrEF, and HF with reduced EF (HFrEF). Baseline characteristics, cumulative incidence and hazard ratios for stroke/SE, major bleeding, and mortality were compared among the four groups. Results Proportion of patients with HF was 10.3%: HFpEF, 43.7%; HFmrEF, 23.6%; HFrEF, 32.7%. CHA2DS2-VASc score was significantly higher in the HFpEF, HFmrEF, and HFrEF groups than the no-HF group (4.0±1.7, 3.8±1.8, 3.5±1.8, and 2.5±1.6, respectively). Oral anticoagulants were administered in 83.6% of patients with CHA2DS2-VASc score ≥1. Annual incidence of stroke/SE was 2.0% in HFpEF group, 0.6% in HFmrEF group, 1.1% in HFrEF group, and 0.7% in no-HF group for 23.0±9.5 months of follow-up period. Cumulative incidence of stroke/SE was significantly higher in the HFpEF group than the no-HF and HFmrEF groups (p<0.001 and p=0.042, respectively; Figure). Risk for stroke/SE was significantly higher in the HFpEF group than the no-HF group [hazard ratio, 1.929; 95% confidence interval, 1.171–3.179, p=0.010]. There were no significant differences in risk for stroke/SE in the HFmrEF and HFrEF groups, compared with the no-HF group. There were no significant differences in major bleeding and mortality among the groups. Conclusions Risk for stroke/SE is highest in HFpEF and lowest in HFmrEF in patients with AF and HF.

Background. Hospital case fatality among those with heart failure in Africa ranges from 9% to 12.5%. An integrated approach to identify those who are at high risk and implementing specific treatment strategies is of great importance for a better outcome. Objective. The aim of this study is to assess the mortality rate and its associated factors among hospitalized heart failure patients at the Jimma University Medical Center (JUMC), south west Ethiopia. Method. A hospital-based retrospective cross-sectional study design was conducted among 252 patients admitted with heart failure during the study period who were sampled and enrolled in to the study. A simple random sampling technique was used to select the study participants by using their medical registration number as the sampling frame. Data were collected using a pretested questionnaire. The collected data were entered into EpiData software and exported to SPSS version 20 for cleaning and analysis. A binary logistic regression model was used. Adjusted and crude odds ratio with 95% CI were used. A P value less than 0.05 was used to declare statistical significance. Results. The prevalence of in-hospital mortality was found to be 21.29%. Cardiogenic shock AOR: 0.016 (95% CI: 0.001–0.267), complication at admission AOR: 5.25 (95% CI: 1.28–21.6), and ejection fraction (<30) AOR: 0.112 (95% CI: 0.022–0.562) were found to be significantly associated factors. Conclusion. The in-hospital mortality rate among admitted heart failure patients is unacceptably high. Due emphasis should be given on the identified associated factors to reduce the mortality.

Abstract Background Ischemic cardiomyopathy (ICM) is often associated with negative LV remodelling after myocardial infarction, sometimes resulting in impaired LV function and dilation (iDCM). 4D Flow CMR has been recently exploited to assess intracardiac hemodynamic changes in presence of LV remodelling. Purpose To quantify 4D Flow intracardiac kinetic energy (KE) and viscous energy loss (EL) and investigate their relation with LV dysfunction and remodelling. Methods Patients with prior anterior myocardial infarction underwent a CMR study with 4D Flow sequences acquisition; they were divided into ICM (n=10) and iDCM (n=10, EDV>208 ml and EF<40%). 10 controls were used for comparison. LV was semi-automatically segmented using short axis CMR stacks and co-registered with 4D Flow. Global KE and EL were computed over the cardiac cycle. NT-proBNP measurements were correlated with average and peak values, during systole and diastole. Results Both LV volume and EF significantly differ (P<0.0001) between iDCM (EDV=294±56 ml, EF=24±8%), ICM (EDV=181±32 ml, EF=34±6%) and controls (EDV=124±29 ml, EF=72±5%). If compared to controls, both ICM and iDCM showed significantly lower KE (P≤0.0008); though lower than controls, EL was higher in iDCM than ICM. Within the iDCM subgroup, diastolic mean KE and peak EL reported good inverse correlation with NT-proBNP (r=−0.75 and r=−0.69, respectively). EL indexed (ELI) to average KE during systole was higher in the entire ischemic group as compared to controls (ELI(ischemic) = 0.17 vs. ELI(controls) = 0.10, P=0.0054). Conclusions 4D Flow analyses effectively mapped post-ischemic LV energetic changes, highlighting the disproportionate intraventricular EL relative to produced KE; preliminary good correlation between LV energetic changes and NT-proBNP will deserve further investigation in order to contribute to early detection of heart failure.

Abstract Background Prevalence of congestive heart failure (CHF) and predisposing conditions has described previously. Most of these studies evaluated centre-European or north-American populations. However, the prevalence and evolutionary changes of Heart Failure stages A, B and C has not been fully elucidated in Mediterranean cohorts. Purpose To estimate the prevalence of CHF (HF Stage C) and four additional key chronic cardiovascular, metabolic and renal conditions predisposing to the development of CHF (HF Stages A and B) at a population level in a south-European healthcare area. We analysed the evolutionary changes in the prevalence in these five conditions. Methods In a healthcare area of 1,3Millions inhabitants, we extracted health related information of all individuals ≥55 years old. We analysed data of 375,233 individuals included in the population-based healthcare database of a public Institute of Health between 2015 and 2017. The conditions of interest were CHF, chronic kidney disease (CKD), diabetes mellitus (DM), ischemic heart disease (IHD) and hypertension (HTN). Results The prevalence of chronic conditions was high, particularly of HTN (48.2–48.9%) and DM individuals (14.6–14.8%). The other conditions were less frequent, with prevalence around 2–4% for IHD, 5–9% for CKD and 2–4% for CHF (Table). However, the less frequent conditions had a striking upward trend with over 1,500 new prevalent cases per year between 2015 and 2017 for CHF (45% relative increase), more than 2,500 new prevalent cases for IHD (67% relative increase) and more than 4,000 new prevalent cases per year for CKD (44% relative increase). Conclusion In this south European cohort, there were a high prevalence of HTN and DM as risk factors and a significant trend of increasing prevalence in high cost chronic conditions such as CHF, IHD and CKD.

Abstract Background Serum uric acid (SUA) is a biomarker of several pathobiologies relevant to the pathogenesis of heart failure with preserved ejection fraction (HFpEF), though by itself may also worsen outcomes. In HF with reduced EF, SUA is independently associated with adverse outcomes and sacubitril/valsartan reduces SUA compared to enalapril. These effects in HFpEF have not been delineated. Purpose To determine the prognostic value of SUA, relationship of change in SUA to quality of life and outcomes, and influence of sacubitril/valsartan on SUA in HFpEF. Methods We analyzed 4,795 participants from the Prospective Comparison of ARNI with ARB Global Outcomes in HF with Preserved Ejection Fraction (PARAGON-HF) trial. We related baseline hyperuricemia to the primary outcome (CV death and total HF hospitalization), its components, myocardial infarction or stroke, and a renal composite outcome. At the 4-month visit, the relationship between SUA change and Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OSS) and several biomarkers including N-terminal pro-B-type natriuretic peptide (NT-proBNP) were also assessed. We simultaneously adjusted for baseline and time-updated SUA to determine whether lowering SUA was associated with clinical benefit. Results Average age was 73±8 years and 52% were women. After multivariable adjustment, hyperuricemia was associated with increased risk for most outcomes (primary outcome HR 1.61, 95% CI 1.37, 1.90, Fig 1A). The treatment effect of sacubitril/valsartan for the primary outcome was not modified by baseline SUA (interaction p=0.11). Sacubitril/valsartan reduced SUA −0.38 mg/dL (95% CI: −0.45, −0.31) compared with valsartan (Fig 1B), with greater effect in those with baseline hyperuricemia (−0.50 mg/dL) (interaction p=0.013). Change in SUA was independently and inversely associated with change in KCCQ-OSS (p=0.019) and eGFR (p<0.001), but not NT-proBNP (p=0.52). Time-updated SUA was a stronger predictor of adverse outcomes over baseline SUA. Conclusions SUA independently predicts adverse outcomes in HFpEF. Sacubitril/valsartan significantly reduces SUA compared to valsartan, an effect that was stronger in those with higher baseline SUA, and reducing SUA was associated with improved outcomes.
