We analysed the prevalence, characteristics and prognostic impact of both conditions across American College of Cardiology/American Heart Association (ACC/AHA) precursor and HF stages A-D. Methods and results 2496 participants from three non-pharmacological German Competence Network HF studies were categorized by ACC/AHA stage; stage C patients were subdivided into C1 and C2 (corresponding to NYHA classes I/II and III, respectively). Overall, patient distribution was 8.1\%/35.3\%/32.9\% and 23.7\% in ACC/AHA stages A/B/C1 and C2/D, respectively. These subgroups were stratified by the absence ( - ) or presence ( +) of CKD (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73m2) and anaemia (haemoglobin in women/men < 12/ < 13 g/dL). The primary outcome was all-cause mortality at 5-year follow-up. Prevalence increased across stages A/B/C1 and C2/D (CKD: 22.3\%/23.6\%/31.6\%/54.7\%; anaemia: 3.0\%/7.9\%/21.7\%/33.2\%, respectively), with concordant decreases in median eGFR and haemoglobin (all p < 0.001). Across all stages, hazard ratios [95\% confidence intervals] for all-cause mortality were 2.1 [1.8-2.6] for CKD + , 1.7 [1.4-2.0] for anaemia, and 3.6 [2.9-4.6] for CKD + /anaemia + (all p < 0.001). Population attributable fractions (PAFs) for 5-year mortality related to CKD and/or anaemia were similar across stages A/B, C1 and C2/D (up to 33.4\%, 30.8\% and 34.7\%, respectively). Conclusions Prevalence and severity of CKD and anaemia increased across ACC/AHA stages. Both conditions were individually and additively associated with increased 5-year mortality risk, with similar PAFs in asymptomatic patients and those with symptomatic HF.}, language = {en} } @article{HennegesMorbachSahitietal.2022, author = {Henneges, Carsten and Morbach, Caroline and Sahiti, Floran and Scholz, Nina and Frantz, Stefan and Ertl, Georg and Angermann, Christiane E. and St{\"o}rk, Stefan}, title = {Sex-specific bimodal clustering of left ventricular ejection fraction in patients with acute heart failure}, series = {ESH Heart Failure}, volume = {9}, journal = {ESH Heart Failure}, number = {1}, doi = {10.1002/ehf2.13618}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-265839}, pages = {786-790}, year = {2022}, abstract = {Aims There is an ongoing discussion whether the categorization of patients with heart failure according to left ventricular ejection fraction (LVEF) is scientifically justified and clinically relevant. Major efforts are directed towards the identification of appropriate cut-off values to correctly allocate heart failure-specific pharmacotherapy. Alternatively, an LVEF continuum without definite subgroups is discussed. This study aimed to evaluate the natural distribution of LVEF in patients presenting with acutely decompensated heart failure and to identify potential subgroups of LVEF in male and female patients. Methods and results We identified 470 patients (mean age 75 ± 11 years, n = 137 female) hospitalized for acute heart failure in whom LVEF could be quantified by Simpson's method in an in-hospital echocardiogram. Non-parametric modelling revealed a bimodal shape of the LVEF distribution. Parametric modelling identified two clusters suggesting two LVEF peaks with mean (variance) of 61\% (9\%) and 31\% (10\%), respectively. Sub-differentiation by sex revealed a sex-specific bimodal clustering of LVEF. The respective threshold differentiating between 'high' and 'low' LVEF was 45\% in men and 52\% in women. Conclusions In patients presenting with acute heart failure, LVEF clustered in two subgroups and exhibited profound sex-specific distributional differences. These findings might enrich the scientific process to identify distinct subgroups of heart failure patients, which might each benefit from respectively tailored (pharmaco)therapies.}, language = {en} } @article{MorbachBeyersdorfKerkauetal.2021, author = {Morbach, Caroline and Beyersdorf, Niklas and Kerkau, Thomas and Ramos, Gustavo and Sahiti, Floran and Albert, Judith and Jahns, Roland and Ertl, Georg and Angermann, Christiane E. and Frantz, Stefan and Hofmann, Ulrich and St{\"o}rk, Stefan}, title = {Adaptive anti-myocardial immune response following hospitalization for acute heart failure}, series = {ESC Heart Failure}, volume = {8}, journal = {ESC Heart Failure}, number = {4}, doi = {10.1002/ehf2.13376}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-258907}, pages = {3348-3353}, year = {2021}, abstract = {Aims It has been hypothesized that cardiac decompensation accompanying acute heart failure (AHF) episodes generates a pro-inflammatory environment boosting an adaptive immune response against myocardial antigens, thus contributing to progression of heart failure (HF) and poor prognosis. We assessed the prevalence of anti-myocardial autoantibodies (AMyA) as biomarkers reflecting adaptive immune responses in patients admitted to the hospital for AHF, followed the change in AMyA titres for 6 months after discharge, and evaluated their prognostic utility. Methods and results AMyA were determined in n = 47 patients, median age 71 (quartiles 60; 80) years, 23 (49\%) female, and 24 (51\%) with HF with preserved ejection fraction, from blood collected at baseline (time point of hospitalization) and at 6 month follow-up (visit F6). Patients were followed for 18 months (visit F18). The prevalence of AMyA increased from baseline (n = 21, 45\%) to F6 (n = 36, 77\%; P < 0.001). At F6, the prevalence of AMyA was higher in patients with HF with preserved ejection fraction (n = 21, 88\%) compared with patients with reduced ejection fraction (n = 14, 61\%; P = 0.036). During the subsequent 12 months after F6, that is up to F18, patients with newly developed AMyA at F6 had a higher risk for the combined endpoint of death or rehospitalization for HF (hazard ratio 4.79, 95\% confidence interval 1.13-20.21; P = 0.033) compared with patients with persistent or without AMyA at F6. Conclusions Our results support the hypothesis that AHF may induce patterns of adaptive immune responses. More studies in larger populations and well-defined patient subgroups are needed to further clarify the role of the adaptive immune system in HF progression.}, language = {en} } @article{AngermannAssmusAnkeretal.2020, author = {Angermann, Christiane E. and Assmus, Birgit and Anker, Stefan D. and Asselbergs, Folkert W. and Brachmann, Johannes and Brett, Marie-Elena and Brugts, Jasper J. and Ertl, Georg and Ginn, Greg and Hilker, Lutz and Koehler, Friedrich and Rosenkranz, Stephan and Zhou, Qian and Adamson, Philip B. and B{\"o}hm, Michael}, title = {Pulmonary artery pressure-guided therapy in ambulatory patients with symptomatic heart failure: the CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF)}, series = {European Journal of Heart Failure}, volume = {22}, journal = {European Journal of Heart Failure}, number = {10}, doi = {10.1002/ejhf.1943}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-218061}, pages = {1891 -- 1901}, year = {2020}, abstract = {Aims Heart failure (HF) leads to repeat hospitalisations and reduces the duration and quality of life. Pulmonary artery pressure (PAP)-guided HF management using the CardioMEMS™ HF system was shown to be safe and reduce HF hospitalisation (HFH) rates in New York Heart Association (NYHA) class III patients. However, these findings have not been replicated in health systems outside the United States. Therefore, the CardioMEMS European Monitoring Study for Heart Failure (MEMS-HF) evaluated the safety, feasibility, and performance of this device in Germany, The Netherlands, and Ireland. Methods and results A total of 234 NYHA class III patients (68 ± 11 years, 22\% female, ≥1 HFH in the preceding year) from 31 centres were implanted with a CardioMEMS sensor and underwent PAP-guided HF management. One-year rates of freedom from device- or system-related complications and from sensor failure (co-primary outcomes) were 98.3\% [95\% confidence interval (CI) 95.8-100.0] and 99.6\% (95\% CI 97.6-100.0), respectively. Survival rate was 86.2\%. For the 12 months post- vs. pre-implant, HFHs decreased by 62\% (0.60 vs. 1.55 events/patient-year; hazard ratio 0.38, 95\% CI 0.31-0.48; P < 0.0001). After 12 months, mean PAP decreased by 5.1 ± 7.4 mmHg, Kansas City Cardiomyopathy Questionnaire (KCCQ) overall/clinical summary scores increased from 47.0 ± 24.0/51.2 ± 24.8 to 60.5 ± 24.3/62.4 ± 24.1 (P < 0.0001), and the 9-item Patient Health Questionnaire sum score improved from 8.7 ± 5.9 to 6.3 ± 5.1 (P < 0.0001). Conclusion Haemodynamic-guided HF management proved feasible and safe in the health systems of Germany, The Netherlands, and Ireland.

We investigated changes in LVEF and covariates at 6-months' follow-up in patients with a predischarge LVEF ≤40\%, and determined predictors and prognostic implications of LVEF changes through 18-months' follow-up. Methods and Results Interdisciplinary Network Heart Failure program participants (n=633) were categorized into subgroups based on LVEF at 6-months' follow-up: normalized LVEF (>50\%; heart failure with normalized ejection fraction, n=147); midrange LVEF (41\%-50\%; heart failure with midrange ejection fraction, n=195), or persistently reduced LVEF (≤40\%; heart failure with persistently reduced LVEF , n=291). All received guideline-directed medical therapies. At 6-months' follow-up, compared with patients with heart failure with persistently reduced LVEF, heart failure with normalized LVEF or heart failure with midrange LVEF subgroups showed greater reductions in LV end-diastolic/end-systolic diameters (both P<0.001), and left atrial systolic diameter (P=0.002), more increased septal/posterior end-diastolic wall-thickness (both P<0.001), and significantly greater improvement in diastolic function, biomarkers, symptoms, and health status. Heart failure duration <1 year, female sex, higher predischarge blood pressure, and baseline LVEF were independent predictors of LVEF improvement. Mortality and event-free survival rates were lower in patients with heart failure with normalized LVEF (P=0.002). Overall, LVEF increased further at 18-months' follow-up (P<0.001), while LV end-diastolic diameter decreased (P=0.048). However, LVEF worsened (P=0.002) and LV end-diastolic diameter increased (P=0.047) in patients with heart failure with normalized LVEF hospitalized between 6-months' follow-up and 18-months' follow-up. Conclusions Six-month survivors of acute cardiac decompensation for systolic heart failure showed variable LVEF trajectories, with >50\% showing improvements by ≥1 LVEF category. LVEF changes correlated with various parameters, suggesting multilevel reverse remodeling, were predictable from several baseline characteristics, and were associated with clinical outcomes at 18-months' follow-up.

Their comparative impact on physical impairment in HFpEF and HFrEF has not been evaluated so far. Methods and results The frequency of 12 comorbidities and their impact on NYHA class and SF-36 physical functioning score (SF-36 PF) were evaluated in 1,294 patients with HFpEF and 2,785 with HFrEF. HFpEF patients had lower NYHA class (2.0 ± 0.6 vs. 2.4 ± 0.6, p < 0.001) and higher SF-36 PF score (54.4 ± 28.3 vs. 54.4 ± 27.7, p < 0.001). All comorbidities were significantly (p < 0.05) more frequent in HFrEF, except hypertension and obesity, which were more frequent in HFpEF (p < 0.001). Adjusting for age and gender, COPD, anemia, hyperuricemia, atrial fibrillation, renal dysfunction, cerebrovascular disease and diabetes had a similar (p for interaction > 0.05) negative effect in both groups. Obesity, coronary artery disease and peripheral arterial occlusive disease exerted a significantly (p < 0.05) more adverse effect in HFpEF, while hypertension and hyperlipidemia were associated with fewer (p < 0.05) symptoms in HFrEF only. The total impact of comorbidities on NYHA (AUC for prediction of NYHA III/IV vs. I/II) and SF-36 PF (r 2) in multivariate analyses was approximately 1.5-fold higher in HFpEF, and also much stronger than the impact of a 10\% decrease in ejection fraction in HFrEF or a 5 mm decrease in left ventricular end-diastolic diameter in HFpEF.

Methods: 3304 patients with heart failure from 9 different studies were included (mean age 63 +/- 14 years); out of these, 711 subjects had preserved left ventricular ejection fraction (>= 50\%) and 994 patients in the whole cohort suffered from diabetes. Results: The majority (>90\%) of heart failure patients with reduced ejection fraction (SHF) and diabetes were treated with an ACE inhibitor (ACEi) or angiotensin receptor blocker (ARB) or with beta-blockers. By contrast, patients with diabetes and preserved ejection fraction (HFNEF) were less likely to receive these substance classes (p < 0.001) and had a worse blood pressure control (p < 0.001). In comparison to patients without diabetes, the probability to receive these therapies was increased in diabetic HFNEF patients (p < 0.001), but not in diabetic SHF patients. Aldosterone receptor blockers were given more often to diabetic patients with reduced ejection fraction (p < 0.001), and the presence and severity of diabetes decreased the probability to receive this substance class, irrespective of renal function.

Agedependent cut-off values below the lower fifth percentile (LLN) of this ratio derived from the general population have been proposed as an alternative. We wanted to assess the diagnostic accuracy and prognostic capability of the GOLD and LLN definition when compared to an expert-based diagnosis. Methods: In a prospective cohort study, 405 patients aged ≥ 65 years with a general practitioner's diagnosis of COPD were recruited and followed up for 4.5 (median; quartiles 3.9; 5.1) years. Prevalence rates of COPD according to GOLD and three LLN definitions and diagnostic performance measurements were calculated. The reference standard was the diagnosis of COPD of an expert panel that used all available diagnostic information, including spirometry and bodyplethysmography. Results: Compared to the expert panel diagnosis, 'GOLD-COPD' misclassified 69 (28\%) patients, and the three LLNs misclassified 114 (46\%), 96 (39\%), and 98 (40\%) patients, respectively. The GOLD classification led to more false positives, the LLNs to more false negative diagnoses. The main predictors beyond the FEV1/FVC ratio for an expert diagnosis of COPD were the FEV1 \% predicted, and the residual volume/total lung capacity ratio (RV/TLC). Adding FEV1 and RV/TLC to GOLD or LLN improved the diagnostic accuracy, resulting in a significant reduction of up to 50\% of the number of misdiagnoses. The expert diagnosis of COPD better predicts exacerbations, hospitalizations and mortality than GOLD or LLN. Conclusions: GOLD criteria over-diagnose COPD, while LLN definitions under-diagnose COPD in elderly patients as compared to an expert panel diagnosis. Incorporating FEV1 and RV/TLC into the GOLD-COPD or LLN-based definition brings both definitions closer to expert panel diagnosis of COPD, and to daily clinical practice.}, subject = {Medizin}, language = {en} }
