RESUMO
BACKGROUND: Empagliflozin reduces the risk of cardiovascular death or hospitalization for heart failure in patients with heart failure with preserved ejection fraction, but additional data are needed about its effect on inpatient and outpatient heart failure events. METHODS: We randomly assigned 5988 patients with class II through IV heart failure with an ejection fraction of >40% to double-blind treatment with placebo or empagliflozin (10 mg once daily), in addition to usual therapy, for a median of 26 months. We prospectively collected information on inpatient and outpatient events reflecting worsening heart failure and prespecified their analysis in individual and composite end points. RESULTS: Empagliflozin reduced the combined risk of cardiovascular death, hospitalization for heart failure, or an emergency or urgent heart failure visit requiring intravenous treatment (432 versus 546 patients [empagliflozin versus placebo, respectively]; hazard ratio, 0.77 [95% CI, 0.67-0.87]; P<0.0001). This benefit reached statistical significance at 18 days after randomization. Empagliflozin reduced the total number of heart failure hospitalizations that required intensive care (hazard ratio, 0.71 [95% CI, 0.52-0.96]; P=0.028) and the total number of all hospitalizations that required a vasopressor or positive inotropic drug (hazard ratio, 0.73 [95% CI, 0.55-0.97]; P=0.033). Compared with patients in the placebo group, fewer patients in the empagliflozin group reported outpatient intensification of diuretics (482 versus 610; hazard ratio, 0.76 [95% CI, 0.67-0.86]; P<0.0001), and patients assigned to empagliflozin were 20% to 50% more likely to have a better New York Heart Association functional class, with significant effects at 12 weeks that were maintained for at least 2 years. The benefit on total heart failure hospitalizations was similar in patients with an ejection fraction of >40% to <50% and 50% to <60%, but was attenuated at higher ejection fractions. CONCLUSIONS: In patients with heart failure with preserved ejection fraction, empagliflozin produced a meaningful, early, and sustained reduction in the risk and severity of a broad range of inpatient and outpatient worsening heart failure events.

BACKGROUND: Empagliflozin reduces the risk of cardiovascular death or hospitalization for heart failure in patients with heart failure and a reduced ejection fraction, with or without diabetes, but additional data are needed about the effect of the drug on inpatient and outpatient events that reflect worsening heart failure. METHODS: We randomly assigned 3730 patients with class II to IV heart failure with an ejection fraction of ≤40% to double-blind treatment with placebo or empagliflozin (10 mg once daily), in addition to recommended treatments for heart failure, for a median of 16 months. We prospectively collected information on inpatient and outpatient events reflecting worsening heart failure and prespecified their analysis in individual and composite end points. RESULTS: Empagliflozin reduced the combined risk of death, hospitalization for heart failure or an emergent/urgent heart failure visit requiring intravenous treatment (415 versus 519 patients; empagliflozin versus placebo, respectively; hazard ratio [HR], 0.76; 95% CI, 0.67-0.87; P<0.0001). This benefit reached statistical significance at 12 days after randomization. Empagliflozin reduced the total number of heart failure hospitalizations that required intensive care (HR, 0.67; 95% CI, 0.50-0.90; P=0.008) and that required a vasopressor or positive inotropic drug or mechanical or surgical intervention (HR, 0.64; 95% CI, 0.47-0.87; P=0.005). As compared with placebo, fewer patients in the empagliflozin group reported intensification of diuretics (297 versus 414 [HR, 0.67; 95% CI, 0.56-0.78; P<0.0001]). Additionally, patients assigned to empagliflozin were 20% to 40% more likely to experience an improvement in New York Heart Association functional class and were 20% to 40% less likely to experience worsening of New York Heart Association functional class, with statistically significant effects that were apparent 28 days after randomization and maintained during long-term follow-up. The risk of any inpatient or outpatient worsening heart failure event in the placebo group was high (48.1 per 100 patient-years of follow-up), and it was reduced by empagliflozin (HR, 0.70; 95% CI, 0.63-0.78; P<0.0001). CONCLUSIONS: In patients with heart failure and a reduced ejection fraction, empagliflozin reduced the risk and total number of inpatient and outpatient worsening heart failure events, with benefits seen early after initiation of treatment and sustained for the duration of double-blind therapy.

In preclinical studies, endothelin receptor A (ETA) antagonists (ETAi) attenuated the progression of heart failure (HF). However, clinical HF trials failed to demonstrate beneficial effects of ETAi. These conflicting data may be explained by the possibility that established HF drugs such as adrenergic receptor blockers interfered with the mechanism of ETAi action in clinical trials. Here we report that mice lacking ETA only in sympathetic neurons (SN-KO) showed less adverse structural remodeling and cardiac dysfunction in response to pathological pressure overload induced by transverse aortic constriction (TAC). In contrast, mice lacking ETA only in cardiomyocytes (CM-KO) were not protected. TAC led to a disturbed sympathetic nerve function as measured by cardiac norepinephrine (NE) tissue levels and [(124)I]-metaiodobenzylguanidine-PET, which was prevented in SN-KO. In a rat model of HF, ETAi improved cardiac and sympathetic nerve function. In cocultures of cardiomyocytes (CMs) and sympathetic neurons (SNs), endothelin-1 (ET1) led to a massive NE release and exaggerated CM hypertrophy compared with CM monocultures. ETA-deficient CMs gained a hypertrophic response through wild-type SNs, but ETA-deficient SNs failed to mediate exaggerated CM hypertrophy. Furthermore, ET1 mediated its effects indirectly via NE in CM-SN cocultures through adrenergic receptors and histone deacetylases, resulting in activation of the prohypertrophic transcription factor myocyte enhancer factor 2. In conclusion, sympathetic ETA amplifies ET1 effects on CMs through adrenergic signaling pathways. Thus, antiadrenergic therapies may blunt potentially beneficial effects of ETAi. Taken together, this may indicate that patients with ß blocker intolerance or disturbed sympathetic nerve function could be evaluated for a potential benefit from ETAi.

IMPORTANCE: Depression is frequent in patients with heart failure and is associated with adverse clinical outcomes. Long-term efficacy and safety of selective serotonin reuptake inhibitors in these patients are unknown. OBJECTIVE: To determine whether 24 months of treatment with escitalopram improves mortality, morbidity, and mood in patients with chronic systolic heart failure and depression. DESIGN, SETTING, AND PARTICIPANTS: The Effects of Selective Serotonin Re-Uptake Inhibition on Morbidity, Mortality, and Mood in Depressed Heart Failure Patients (MOOD-HF) study was a double-blind, placebo-controlled randomized clinical trial conducted at 16 tertiary medical centers in Germany. Between March 2009 and February 2014, patients at outpatient clinics with New York Heart Association class II-IV heart failure and reduced left ventricular ejection fraction (<45%) were screened for depression using the 9-item Patient Health Questionnaire. Patients with suspected depression were then invited to undergo a Structured Clinical Interview based on the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) to establish the diagnosis. INTERVENTIONS: Patients were randomized 1:1 to receive escitalopram (10-20 mg) or matching placebo in addition to optimal heart failure therapy. Study duration was 24 months. MAIN OUTCOMES AND MEASURES: The composite primary outcome was time to all-cause death or hospitalization. Prespecified secondary outcomes included safety and depression severity at 12 weeks of treatment (including the titration period), which were determined using the 10-item Montgomery-Åsberg Depression Rating Scale (total possible score, 0 to 60; higher scores indicate more severe depression). RESULTS: A total of 372 patients (mean age, 62 years; 24% female) were randomized and had taken at least 1 dose of study medication when the data and safety monitoring committee recommended the trial be stopped early. During a median participation time of 18.4 months (n = 185) for the escitalopram group and 18.7 months (n = 187) for the placebo group, the primary outcome of death or hospitalization occurred in 116 (63%) patients and 119 (64%) patients, respectively (hazard ratio, 0.99 [95% CI, 0.76 to 1.27]; P = .92). The mean Montgomery-Åsberg Depression Rating Scale sum score changed from 20.2 at baseline to 11.2 at 12 weeks in the escitalopram group and from 21.4 to 12.5 in the placebo group (between-group difference, -0.9 [95% CI,-2.6 to 0.7]; P = .26). Safety parameters were comparable between groups. CONCLUSIONS AND RELEVANCE: In patients with chronic heart failure with reduced ejection fraction and depression, 18 months of treatment with escitalopram compared with placebo did not significantly reduce all-cause mortality or hospitalization, and there was no significant improvement in depression. These findings do not support the use of escitalopram in patients with chronic systolic heart failure and depression. TRIAL REGISTRATION: isrctn.com Identifier: ISRCTN33128015.

Impairment of the cardiac norepinephrine (NE) reuptake by the neuronal NE transporter contributes to enhanced cardiac NE net release in congestive heart failure. Elevated plasma levels of aldosterone (AL) promote sympathetic overstimulation in failing hearts by unclear mechanisms. Our aim was to evaluate if elevated AL and/or alterations in Na(+) intake regulate cardiac NE reuptake. To test the effects of AL and Na(+) on cardiac NE reuptake, Wistar rats were fed a normal-salt (NS) diet (0.2% NaCl), a low-salt (LS) diet (0.015% NaCl), or a high-salt (HS) diet (8% NaCl). Another group of animals received AL infusion alone (0.75 µg/h) or AL infusion plus HS diet. Specific cardiac [(3)H]NE uptake via the NE transporter in a Langendorff preparation and AL plasma levels were measured at different time points between 5 and 42 days of treatment. To compare these findings from healthy animals with a disease model, Dahl salt-sensitive rats were investigated as a model of congestive heart failure with endogenously elevated AL. In summary, neither exogenous nor endogenous elevations of AL alone were sufficient to reduce cardiac NE reuptake. Only the HS diet induced a reduction of NE reuptake by 26%; additional infusion of AL augmented this effect to a further reduction of NE reuptake by 36%. In concordance, Dahl salt-sensitive rats treated with a HS diet displayed elevated AL and a marked reduction of NE reuptake. We conclude that exogenous or endogenous AL elevations alone do not reduce cardiac NE reuptake, but AL serves as an additional factor that negatively regulates cardiac NE reuptake in concert with HS intake.

BACKGROUND: Chronic heart failure (CHF) patients suffer from multiple and agonizing symptoms like shortness of breath and reduced functional status, the latter of which is usually assessed using New York Heart Association (NYHA) functional class. PURPOSE: In order to identify potentially modifiable factors of reduced functional status in patients with CHF, we investigated somatic and psychosocial correlates of NYHA functional class. We subsequently compared the results to correlates of left ventricular ejection fraction (LVEF) as an objective parameter of disease severity. METHODS: The cross-sectional study (n = 314) was part of the German Heart Failure Network. Data were analysed using a logistic regression modelling process. RESULTS: In the final regression model, NYHA functional class was only significantly associated with depression (odds ratio (OR) = 1.18; 95% confidence interval (CI) = 1.09-1.27) and multimorbidity (OR = 1.17; 95% CI = 1.04-1.32). LVEF was associated with amino-terminal pro-brain natriuretic peptide (NT-proBNP) (OR = 0.60; 95% CI = 0.44-0.82), aetiology of CHF (OR = 2.08; 95% CI = 1.11-3.90), and smoking (OR = 2.21; 95% CI = 1.25-3.91). CONCLUSIONS: Whereas LVEF was not related to depression, our data revealed a close association between functional status (as assessed by NYHA functional class) and depression in patients with CHF, even after adjusting for cardiac and socio-demographic variables. Different forms of underlying causal mechanisms could be suspected; it appears promising to further investigate this specific interaction. In any event, pending further investigation, our results underscore the need to examine CHF patients with respect to both somatic symptom burden and potential depressive disorders.

Background: Patients with chronic heart failure (CHF) frequently suffer from depressive comorbidity. CHF and depressive comorbidity can cause somatic symptoms. The correct attribution of somatic symptoms is important. Thus, we aimed to assess potential differences in somatic symptom severity between CHF patients with and without depressive comorbidity. Methods: We evaluated depressive comorbidity using the Patient Health Questionnaire-9 (PHQ-9), somatic symptom severity with the Patient Health Questionnaire-15 (PHQ-15), and sociodemographic and medical variables in 308 CHF outpatients. To compare somatic symptom severity between CHF patients with and without depressive comorbidity, we conducted item-level analyses of covariance. Results: Of the 308 participating patients, 93 (30.3%) met the PHQ-9 criteria for depressive comorbidity. These patients did not differ from those without depressive comorbidity with regard to age, sex, left ventricular function, and multimorbidity. Patients with depressive comorbidity scored significantly higher on ten out of thirteen PHQ-15 items than patients without depressive comorbidity. The largest effect sizes (0.71-0.80) were shown for symptoms of headache, chest pain, shortness of breath, and palpitations, and the latter three were potentially attributable to heart failure. Conclusions: Among patients with CHF, somatic symptoms are more pronounced in those with depressive comorbidity than those without depressive comorbidity. This finding is especially true for cardiac symptoms independent of CHF severity. The potential interpretation of somatic symptoms as correlates of depressive comorbidity must be recognized in clinical practice.
RESUMO
BACKGROUND: Community-based interventions may promote awareness and adherence to atrial fibrillation (AF)-related therapies, potentially reducing adverse events. The ARENA project investigated the health status, therapies and events in AF patients in the Rhein-Neckar Region, Germany. The subproject "ARENA intervention" studied the effect of community-based interventions on AF-associated outcomes. METHODS: From 2016 onward, patients with diagnosed AF were recruited for the observational ARENA registry. In 2018, an intervention period was initiated involving population-based information campaigns on AF diagnosis and therapies. The "control group" was recruited prior to initiation, and the "intervention group" afterward. Patients underwent standardized follow-up > 1 year after recruitment. Clinical outcomes, therapy and quality of life were compared between the two groups. RESULTS: A total of 2769 patients were included. This real-world cohort showed high adherence to oral anticoagulation therapy (OAC) and an increased use of NOACs over vitamin K antagonists over time. In the intervention group (n = 1362), more patients continued OAC at follow-up (87.1% vs. 81.5%, P = 0.002). However, this difference was not significant in the patient subgroup with class I/IIa indications for OAC (90.1% vs. 87.5%, P = 0.11). AF-related re-hospitalization was lower in the intervention group (6.8% vs. 12.3%, P < 0.001). There was no significant difference in quality of life. AF-related anxiety was reduced at follow-up. Of note, nearly a quarter of all patients stated that ARENA had influenced their health perception. CONCLUSION: Tailored community-based campaigns may raise awareness for AF-related health issues, supporting therapy adherence. Future public strategies to improve quality of life in AF patients should be investigated, as the ARENA project hints at a potential benefit of population-based campaigns.

RESUMO
OBJECTIVE: Atrial fibrillation (AF) is associated with impaired health-related quality of life (HRQoL), an increased risk of morbidity, and mortality. Traditional AF-related outcomes (e.g., AF recurrence) primarily demonstrate the physiological benefits of AF management but do not focus on the benefits experienced subjectively by the patient (i.e., patient-reported outcomes), which have been suggested as optimal endpoints in AF intervention studies. The aim of this study is to identify medical and psychological factors associated with impaired HRQoL at 1-year follow-up. METHODS: Using data from the prospective observational multicenter ARENA study in patients with AF, we analyzed associations between medical factors, anxiety, and HRQoL at 1-year follow-up assessed using 5-level EuroQoL-5D. RESULTS: In 1353 AF patients (mean age 71.4 ± 10.3 years, 33.8% female), none of the medical predictors (e.g., heart disease) or history of cardioversion were associated with HRQoL at the 1-year follow-up. Higher generalized anxiety (ß = -0.114, p < .001) but not cardiac anxiety (ß = -0.006, p = .809) at baseline predicted decreased HRQoL, independent of confounding variables and patients' medical status. Furthermore, the worsening of patients' generalized anxiety was associated with decreased HRQoL (ß = -0.091, p < .001). In contrast, the improvement of generalized anxiety over time predicted higher HRQoL (ß = 0.097, p < .001). Finally, the worsening of patients' cardiac anxiety over time was associated with decreased HRQoL (ß = -0.081, p < .001). CONCLUSION: Our results highlight the importance of anxiety as a predictor of future HRQoL in patients with AF. Additional studies to examine the impact of anxiety treatment on HRQoL in this population are needed.

Aims: Epidemiological surveillance has raised safety concerns for mRNA SARS-CoV-2-vaccination-related myocarditis. We aimed to analyze epidemiological, clinical and imaging findings associated with clinical outcomes in these patients in an international multi-center registry (NCT05268458). Methods and results: Patients with clinical and CMR diagnosis of acute myocarditis within 30 days after mRNA SARS-CoV-2-vaccination were included from five centers in Canada and Germany between 05/21 and 01/22. Clinical follow-up on persistent symptoms was collected. We enrolled 59 patients (80% males, mean age 29 years) with CMR-derived mild myocarditis (hs-Troponin-T 552 [249-1,193] ng/L, CRP 28 [13-51] mg/L; LVEF 57 ± 7%, LGE 3 [2-5] segments). Most common symptoms at baseline were chest pain (92%) and dyspnea (37%). Follow-up data from 50 patients showed overall symptomatic burden improvement. However, 12/50 patients (24%, 75% females, mean age 37 years) reported persisting symptoms (median interval 228 days) of chest pain (n = 8/12, 67%), dyspnea (n = 7/12, 58%), with increasing occurrence of fatigue (n = 5/12, 42%) and palpitations (n = 2/12, 17%). These patients had initial lower CRP, lower cardiac involvement in CMR, and fewer ECG changes. Significant predictors of persisting symptoms were female sex and dyspnea at initial presentation. Initial severity of myocarditis was not associated with persisting complaints. Conclusion: A relevant proportion of patients with mRNA SARS-CoV-2-vaccination-related myocarditis report persisting complaints. While young males are usually affected, patients with persisting symptoms were predominantly females and older. The severity of the initial cardiac involvement not predicting these symptoms may suggest an extracardiac origin.
RESUMO
BACKGROUND: There is limited published information on outcome adjudication in heart failure (HF). OBJECTIVES: The authors sought to compare investigator reports (IRs) to a Clinical Events Committee (CEC) and the impact of SCTI (Standardized Clinical Trial Initiative) criteria. METHODS: In the EMPEROR-Reduced trial, the authors compared IRs to the CEC for concordance; treatment effect on primary composite outcome events; and the components first event hospitalization primarily for HF or cardiovascular mortality (CVM), prognosis after hospitalization for heart failure (HHF), total HHFs, and trial duration with and without SCTI criteria. RESULTS: The CEC confirmed 76.3% of IR events for the primary outcome (CVM: 89.1%; HHF: 73.7%). The HR for treatment effect did not differ between adjudication methods for the primary outcome (IR: 0.75 [95% CI: 0.66-0.85]; CEC: 0.75 [95% CI: 0.65-0.86]), its components, or total HHFs. The prognosis after first HHF for all-cause mortality and CVM also did not differ between IR or CEC. Interestingly, IR primary HHF with different CEC primary cause had the highest subsequent fatal event rate. Full SCTI criteria were present in 90% of CEC HHFs-with a similar treatment effect to non-SCTI. The IR primary event reached the protocol target number (841) 3 months earlier than CEC (4 months with full SCTI criteria). CONCLUSIONS: Investigator adjudication is an alternative to a CEC with similar accuracy and faster event accumulation. The use of granular (SCTI) criteria did not improve trial performance. Finally, our data suggest that consideration be given to broadening the HHF definition to include "for or with" worsening disease.

During the worldwide ongoing immunization campaign against SARS-CoV-2, growing data on very rare but potentially harmful side effects of such vaccines arise since approval trials have not been adequately powered to detect those events. Besides the already reported vaccine-related myocarditis, which primarily occurs in young male individuals, our attention was recently drawn to a series of older male and female patients, who were referred to our institutions with isolated acute pericarditis without myocardial damage, shortly after SARS-CoV-2 vaccination. We describe a series of five adult patients presenting with chest pain, shortness of breath and isolated pericarditis with and without pericardial effusion after SARS-CoV-2 vaccination. All patients underwent echocardiography and cardiac magnetic resonance, and the corresponding findings, including late gadolinium enhancement (LGE) and T1 and T2 mapping are reported herein. To our knowledge, such cases have not been systematically reported in the current literature so far.
RESUMO
BACKGROUND: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with impaired health-related quality of life (HRQoL), high symptom severity, and poor cardiovascular outcomes. Both clinical and psychological factors may contribute to symptom severity and HRQoL in AF. METHODS: Using data from the observational Atrial Fibrillation Rhine-Neckar Region (ARENA) trial, we identified medical and psychosocial factors associated with AF-related symptom severity using European Heart Rhythm Association symptom classification and HRQoL using 5-level EuroQoL- 5D. RESULTS: In 1218 AF patients (mean age 71.1 ± 10.5 years, 34.5% female), female sex (OR 3.7, p < 0.001), preexisting coronary artery disease (CAD) (OR 1.7, p = 0.020), a history of cardioversion (OR 1.4, p = 0.041), cardiac anxiety (OR 1.2; p < 0.001), stress from noise (OR 1.4, p = 0.005), work-related stress (OR 1.3, p = 0.026), and sleep disturbance (OR 1.2, p = 0.016) were associated with higher AF-related symptom severity. CAD (ß = -0.23, p = 0.001), diabetes mellitus (ß = -0.25, p < 0.001), generalized anxiety (ß = -0.30, p < 0.001), cardiac anxiety (ß = -0.16, p < 0.001), financial stress (ß = -0.11, p < 0.001), and sleep disturbance (ß = 0.11, p < 0.001) were associated with impaired HRQoL. CONCLUSIONS: Psychological characteristics, preexisting CAD, and diabetes may play an important role in the identification of individuals at highest risk for impaired HRQoL and high symptom severity in patients with AF.
RESUMO
BACKGROUND: The mode of death has been well characterized in patients with heart failure and a reduced ejection fraction; however, less is known about the mode of death in patients with heart failure and a preserved ejection fraction (HFPEF). The purpose of this study was to examine the mode of death in patients with HFPEF enrolled in the Irbesartan in Heart Failure With Preserved Ejection Fraction Study (I-Preserve) trial and to determine whether irbesartan altered the distribution of mode of death in HFPEF. METHODS AND RESULTS: All deaths were reviewed by a clinical end-point committee, and the mode of death was assigned by consensus of the members. The annual mortality rate was 5.2% in the I-Preserve trial. There were no significant differences in mortality rate between the placebo and irbesartan groups. The mode of death was cardiovascular in 60% (including 26% sudden, 14% heart failure, 5% myocardial infarction, and 9% stroke), noncardiovascular in 30%, and unknown in 10%. There were no differences in the distribution of mode-specific mortality rates between placebo and irbesartan. CONCLUSIONS: Sixty percent of the deaths in patients with HFPEF were cardiovascular, with sudden death and heart failure death being the most common. Treatment with irbesartan did not affect overall mortality or the distribution of mode-specific mortality rates. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov.

BACKGROUND: The postdischarge rehospitalization and death rates are high in patients with acute heart failure (HF) syndromes despite optimization of standard therapy for chronic HF. To the best of our knowledge, there has been no systematic analysis of the causes of death and rehospitalization in this patient population. METHODS: This was a prespecified analysis of adjudicated cause-specific all-cause mortality and cardiovascular (CV) hospitalization in the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST) trial, a randomized, double-blind, placebo-controlled study in patients hospitalized with worsening HF and left ventricular ejection fraction < or =40% comparing tolvaptan, an oral vasopressin receptor antagonist to placebo, in addition to standard care. RESULTS: Of the 4,133 randomized, there were 5,239 rehospitalizations and 1,080 deaths during a median of 9.9 months. Of all deaths, 41.0% were due to HF, 26.0% due to sudden cardiac death (SCD), 2.6% due to acute myocardial infarction (MI), 2.2% due to stroke, and 13.2% due to non-CV causes. Of all hospitalizations, 39.2% were non-CV, whereas 46.3% were for HF, and a minority of hospitalizations was due to stroke, MI, arrhythmia, or other CV causes. CONCLUSIONS: Despite close follow-up and evidence-based therapy within a clinical trial, rehospitalization and death remain high. Although most deaths were from HF, one quarter of patients had SCD. In addition, there were almost as many non-CV hospitalizations as HF hospitalizations. Knowledge of the causes of death and rehospitalization may be essential for proper management and early initiation of therapy.

Myocardial strain is a convenient parameter to quantify left ventricular (LV) function. Fast strain-encoding (fSENC) enables the acquisition of cardiovascular magnetic resonance images for strain-measurement within a few heartbeats during free-breathing. It is necessary to analyze inter-vendor agreement of techniques to determine strain, such as fSENC, in order to compare existing studies and plan multi-center studies. Therefore, the aim of this study was to investigate inter-vendor agreement and test-retest reproducibility of fSENC for three major MRI-vendors. fSENC-images were acquired three times in the same group of 15 healthy volunteers using 3 Tesla scanners from three different vendors: at the German Heart Institute Berlin, the Charité University Medicine Berlin-Campus Buch and the Theresien-Hospital Mannheim. Volunteers were scanned using the same imaging protocol composed of two fSENC-acquisitions, a 15-min break and another two fSENC-acquisitions. LV global longitudinal and circumferential strain (GLS, GCS) were analyzed by a trained observer (Myostrain 5.0, Myocardial Solutions) and for nine volunteers repeatedly by another observer. Inter-vendor agreement was determined using Bland-Altman analysis. Test-retest reproducibility and intra- and inter-observer reproducibility were analyzed using intraclass correlation coefficient (ICC) and coefficients of variation (CoV). Inter-vendor agreement between all three sites was good for GLS and GCS, with biases of 0.01-1.88%. Test-retest reproducibility of scans before and after the break was high, shown by ICC- and CoV values of 0.63-0.97 and 3-9% for GLS and 0.69-0.82 and 4-7% for GCS, respectively. Intra- and inter-observer reproducibility were excellent for both parameters (ICC of 0.77-0.99, CoV of 2-5%). This trial demonstrates good inter-vendor agreement and test-retest reproducibility of GLS and GCS measurements, acquired at three different scanners from three different vendors using fSENC. The results indicate that it is necessary to account for a possible bias (< 2%) when comparing strain measurements of different scanners. Technical differences between scanners, which impact inter-vendor agreement, should be further analyzed and minimized.DRKS Registration Number: 00013253.Universal Trial Number (UTN): U1111-1207-5874.

Transfer of current treatment guidelines for high blood cholesterol into clinical practice, especially under timely consideration of the last coronary angiography (CA), remains unclear. We therefore tested the efficiency of statin treatment in 209 patients with coronary heart disease and allocated them according to the time of the last CA in 2 groups (Assuntos

RESUMO
OBJECTIVE: To determine the factors, which are associated with suicidal ideation and ideas of self-harm in patients with congestive heart failure (CHF). METHODS: We examined 294 patients with documented CHF, New York Heart Association (NYHA) functional class II-IV, in a cross sectional study at three cardiac outpatient departments. Measures included self-reports of suicidal ideation and self-harm (PHQ-9), depression (SCID), health-related quality of life (SF-36), multimorbidity (CIRS-G), consumption of alcoholic beverages, as well as comprehensive clinical status. Data were analyzed using logistic regression analyses. RESULTS: 50 patients (17.1%) reported experiencing suicidal ideation and/or ideas of self-harm on at least several days over the past two weeks. The final regression model revealed significant associations with health-related quality of life, physical component (odds ratio [OR] 0.56; 95% confidence interval [CI]: 0.35-0.91), and mental component (OR 0.50; 95% CI: 0.31-0.82), consumption of alcoholic beverages (OR 1.27; 95% CI: 1.05-1.54), first-episode depression (OR 3.92; 95% CI: 1.16-13.22), and lifetime depression (OR 10.89; 95% CI: 2.49-47.72). Age was only significant in the univariable (P=.03) regression analysis. NYHA functional class, left ventricular ejection fraction (LVEF), etiology of CHF, medication, cardiovascular interventions, multimorbidity, gender, and living situation were not significantly associated with suicidal ideation or ideas of self-harm. CONCLUSIONS: Lifetime depression, in particular, increases the risk of suicidal ideation and ideas of self-harm in CHF patients. Furthermore, the findings of our study underline the necessity of differentiating between first-episode and lifetime depression in CHF-patients in future research and clinical practice.

Vasopressin plays a physiological role in regulation of blood pressure, fluid volume, and serum osmolality. In heart failure inadequate release of vasopressin may result in excess fluid retention and hyponatremia. Vasopressin receptor antagonists are a new class of orally active drugs targeted to inhibit one or more of three distinct vasopressin receptors, namely V1a- (-->vasoconstriction), V1b- (-->release of ACTH) und V2-receptors (-->inhibition of free water reabsorption in the kidney). In cardiac decompensation with fluid overload selective V2- (Lixivaptan, satavaptan and tolvaptan) and non-selective V1a/V2-receptor blockers (Conivaptan) have been shown to be superior to standard therapy, as they allow for a faster weight loss and a more rapid symptomatic improvement (i.e. reduction in dyspnea). Inhibiting free water reabsorption without affecting renal sodium excretion vasopressin receptor antagonists allow for a controlled normalisation of serum natrium in euvolemic and hypervolemic hyponatremia. Vasopressin antagonists are well tolerated and have--in contrast to diuretics--no negative influence on renal function and serum potassium. Heart rate and blood pressure are not affected by vasopressin receptor antagonists. However, despite its excellent acute clinical effects long-term treatment with tolvaptan did not result in a reduced mortality and morbidity in heart failure patients over a mean follow-up of 9.9 months in the EVEREST trial.

BACKGROUND: Psychosocial factors in cardiovascular diseases are increasingly acknowledged by patients, health care providers and payer organizations. Due to the rapidly increasing body of evidence, the German Cardiac Society has commissioned an update of its 2013 position paper on this topic. The German version was published in 2018 and the current manuscript is an extended translation of the original version. METHODS: This position paper provides a synopsis of the state of knowledge regarding psychosocial factors in the most relevant cardiovascular diseases and gives recommendations with respect to their consideration in clinical practice. RESULTS: Psychosocial factors such as low socioeconomic status, acute and chronic stress, depression, anxiety and low social support are associated with an unfavorable prognosis. Psychosocial problems and mental comorbidities should be assessed routinely to initiate targeted diagnostics and treatment. For all patients, treatment should consider age and gender differences as well as individual patient preferences. Multimodal treatment concepts should comprise education, physical exercise, motivational counseling and relaxation training or stress management. In cases of mental comorbidities, brief psychosocial interventions by primary care providers or cardiologists, regular psychotherapy and/or medications should be offered. While these interventions have positive effects on psychological symptoms, robust evidence for possible effects on cardiac outcomes is still lacking. CONCLUSIONS: For coronary heart disease, chronic heart failure, arterial hypertension, and some arrhythmias, there is robust evidence supporting the relevance of psychosocial factors, pointing to a need for considering them in cardiological care. However, there are still shortcomings in implementing psychosocial treatment, and prognostic effects of psychotherapy and psychotropic drugs remain uncertain. There is a need for enhanced provider education and more treatment trials.
