RESUMO

AIMS: Sodium-glucose co-transporter 2 inhibition reduces the risk of hospitalization for heart failure and for death in patients with symptomatic heart failure. However, trials investigating the effects of this drug class in patients following acute myocardial infarction are lacking. METHODS AND RESULTS: In this academic, multicentre, double-blind trial, patients (n = 476) with acute myocardial infarction accompanied by a large creatine kinase elevation (>800 IU/L) were randomly assigned to empagliflozin 10 mg or matching placebo once daily within 72 h of percutaneous coronary intervention. The primary outcome was the N-terminal pro-hormone of brain natriuretic peptide (NT-proBNP) change over 26 weeks. Secondary outcomes included changes in echocardiographic parameters. Baseline median (interquartile range) NT-proBNP was 1294 (757-2246) pg/mL. NT-proBNP reduction was significantly greater in the empagliflozin group, compared with placebo, being 15% lower [95% confidence interval (CI) -4.4% to -23.6%] after adjusting for baseline NT-proBNP, sex, and diabetes status (P = 0.026). Absolute left-ventricular ejection fraction improvement was significantly greater (1.5%, 95% CI 0.2-2.9%, P = 0.029), mean E/e' reduction was 6.8% (95% CI 1.3-11.3%, P = 0.015) greater, and left-ventricular end-systolic and end-diastolic volumes were lower by 7.5 mL (95% CI 3.4-11.5 mL, P = 0.0003) and 9.7 mL (95% CI 3.7-15.7 mL, P = 0.0015), respectively, in the empagliflozin group, compared with placebo. Seven patients were hospitalized for heart failure (three in the empagliflozin group). Other predefined serious adverse events were rare and did not differ significantly between groups. CONCLUSION: In patients with a recent myocardial infarction, empagliflozin was associated with a significantly greater NT-proBNP reduction over 26 weeks, accompanied by a significant improvement in echocardiographic functional and structural parameters.

RESUMO

BACKGROUND: Sodium glucose cotransporter 2 (SGLT2) inhibitors are established antidiabetic drugs with proven cardiovascular benefit. Although growing evidence suggests beneficial effects on myocardial remodeling, fluid balance and cardiac function, the impact of empagliflozin initiated early after acute myocardial infarction (AMI) has not been investigated yet. Therefore, the impact of EMpagliflozin on cardiac function and biomarkers of heart failure in patients with acute MYocardial infarction (EMMY) trial was designed to investigate the efficacy and safety of empagliflozin in diabetic and non-diabetic patients after severe AMI. METHODS: Within a multicenter, randomized, double-blind, placebo-controlled, phase 3b trial we will enroll patients with AMI and characteristics suggestive of severe myocardial necrosis are randomized in a 1:1 ratio to empagliflozin (10 mg once daily) or matching placebo. The primary endpoint is the impact of empagliflozin on changes in NT-proBNP within 6 months after AMI. Secondary endpoints include changes in echocardiographic parameters, levels of ketone body concentrations, HbA1c levels and body weight, respectively. Hospitalization rate due to heart failure or other causes, the duration of hospital stay and all-cause mortality will be assessed as exploratory secondary endpoints. DISCUSSION: The EMMY trial will test empagliflozin in patients with AMI regardless of their diabetic status. The EMMY trial may therefore underpin the concept of SGLT2 inhibition to improve cardiac remodeling, pre-and afterload reduction and cardiac metabolism regardless of its antidiabetic effects. Results will provide the rationale for the conduct of a cardiovascular outcome trial to test the effect of empagliflozin in patients with AMI.

RESUMO

BACKGROUND: According to the World Health Organization, coronary artery disease (CAD), including ST-segment elevation myocardial infarction (STEMI), is the most common cause of death worldwide as well as in Europe and Austria. There is valid data on the impact of conventional risk factors on the medical outcomes for STEMI patients. However, only few studies examine the role of the socio-economic environment for medical outcomes. The main task of this study is to investigate if the socio-economic environment of patients who underwent percutaneous coronary intervention (PCI) after STEMI has an impact on the distribution of risk factors and medical outcomes. METHODS: The study focuses on the population of the City of Vienna, Austria, and includes 870 STEMI patients, who underwent PCI at the General Hospital of Vienna (AKH Wien) between 2008 and 2012. The following data were collected: conventional risk factors (hypertension, hyperlipidemia, diabetes, overweight, smoking, family history and vascular disease) and socio-economic indicators of the patient's residential district (number of residents, income pre-tax, residents per general practitioner, residents per internal specialist, compulsory education only, academic degree and rate of unemployment). Cox regressions were performed to evaluate the impact of socio-economic environment and conventional risk factors on survival. RESULTS: Most of the conventional risk factors show a significant difference between deceased and surviving patients. The study revealed significant differences across districts in relation to the socio-economic background of STEMI patients. Surprisingly, medical outcomes, as measured by the survival of patients, are significantly related to a patient's district of residence (p-Value = 0.028) but not in a systematic way as far as the socio-economic environment of these districts is concerned. CONCLUSIONS: The study provides intuitive evidence for a hitherto understudied Central European context on the link between socio-economic environment and conventional risk factors at population level and the link between conventional risk factors and survival both at the population at the individual level. While this is in line with previous evidence and suggestive of the incorporation of measures of socio-economic status (SES) into policy & guidelines toward the management of CAD, more data on the SES - STEMI nexus are needed at individual level.

RESUMO

BACKGROUND: The underlying reasons for the highly inconsistent clinical outcome data for omega-3-polyunsaturated fatty acids (n3-PUFAs) supplementation in patients with cardiac disease have not been understood yet. The aim of this prospective, randomized, double-blind, placebo controlled study was to determine the effects of oral treatment with n3-PUFAs on the anti-oxidant capacity of HDL in heart failure (HF) patients. METHODS: A total of 40 patients with advanced HF of nonischaemic origin, defined by NT-proBNP levels of >2000 pg/mL, NYHA class III or IV and a LVEF <35% who were on stable optimized medical therapy for ≥3 months, were consecutively enrolled into this prospective, double-blind, placebo-controlled trial and randomized in a 1:1:1 fashion to receive 1 g/day or 4 g/day of n3-PUFA, or placebo, respectively, for 12 weeks. RESULTS: After 12 weeks of treatment, the anti-oxidant function of HDL, measured by the HDL inflammatory index, was found significantly impaired in the treatment group in a dose-dependent fashion with 0.67 [IQR 0.49-1.04] for placebo vs 0.71 [IQR 0.55-1.01] for 1 g/day n3-PUFA vs 0.98 [IQR 0.73-1.16] for 4 g/day n3-PUFA (P for trend = 0.018). CONCLUSION: We provide evidence for an adverse effect of n3-PUFA supplementation on anti-oxidant function of HDL in nonischaemic heart failure patients, establishing a potential mechanistic link for the controversial outcome data on n3-PUFA supplementation.

RESUMO

OBJECTIVES AND BACKGROUND: Polymer coatings of drug-eluting stents (DES) may induce allergic reactions and inflammation, resulting in late-acquired stent malapposition (LASM) with the risk of stent thrombosis. This study evaluated, if biodegradable polymer (BP) reduces the incidence of LASM compared to permanent polymer (PP) after treatment with newer generation DES. METHODS AND RESULTS: Fifty patients with 59 lesions were randomized (2:1) to elective treatment with second generation PP-DES (n = 32, 39 stents), either Everolimus-eluting or Zotarolimus-eluting stents, or with BP-DES (Biolimus-eluting stents [BES]; n = 18, 20 stents) and underwent optical coherence tomography directly after implantation and after 1 year. After implantation acute stent malappositions (ASM) were documented in 30 stents (51%) distributed to 22 stents treated with PP-DES (56%) and 8 with BP-DES (40%; n.s.). After 1 year, late stent malappositions (LSM) were detected in 14 stents (24 %); ASM persisted (APSM) in 9 stents after one year (7 PP-DES-18%, 2 BES-10%), whereas ASM resolved in 21 stents. In addition, LASM was documented in nine stents including five stents without and four stents with additional APSM. All LASM were located in PP-DES (n = 9; 23%), none in BP-DES (P = 0.022). Compared to the reference lumen area, in-stent lumen area of stents without LASM was smaller due to neointimal hyperplasia (P = 0.021), whereas in-stent lumen area at maximum LASM of stents with LASM was larger due to positive remodeling (P = 0.002). CONCLUSIONS: In conclusion the use of BP-DES reduced the occurrence of LASM due to positive remodeling compared to second generation PP-DES.

RESUMO

BACKGROUND: Everolimus-eluting bioresorbable vascular scaffolds (BVS) represent an innovative treatment option for coronary artery disease. Clinical and angiographic results seem promising, however, data on its immediate procedural performance are still scarce. The aim of our study was to assess the mechanical properties of BVS by Optical Coherence Tomography (OCT) in clinical routine. METHODS: Post-implantation OCT images of 40 BVS were retrospectively compared to those of 40 metallic everolimus-eluting stents (EES). Post-procedural device related morphological features were assessed. This included incidences of gross underexpansion and the stent eccentricity index (SEI, minimum/maximum diameter) as a measure for focal radial strength. RESULTS: Patients receiving BVS were younger than those with EES (54.0 ± 11.2 years versus 61.7 ± 11.4 years, p = 0.012), the remaining baseline, vessel and lesion characteristics were comparable between groups. Lesion pre-dilatation was more frequently performed and inflation time was longer in the BVS than in the EES group (n = 34 versus n = 23, p = 0.006 and 44.2 ± 12.8 versus 25.6 ± 8.4 seconds, p < 0.001, respectively). There were no significant differences in maximal inflation pressures and post-dilatation frequencies with non-compliant balloons between groups. Whereas gross device underexpansion was not significantly different, SEI was significantly lower in the BVS group (n = 12 (30 %) versus n = 14 (35 %), p = 0.812 and 0.69 ± 0.08 versus 0.76 ± 0.09, p < 0.001, respectively). There was no difference in major adverse cardiac event-rate at six months. CONCLUSION: Our data show that focal radial expansion was significantly reduced in BVS compared to EES in a clinical routine setting using no routine post-dilatation protocol. Whether these findings have impact on scaffold mid-term results as well as on clinical outcome has to be investigated in larger, randomized trials.

RESUMO

The aim of this study was to evaluate the distribution of platelet reactivity values in patients treated with prasugrel and ticagrelor. This prospective observational study enrolled 200 patients treated with prasugrel or ticagrelor. Platelet aggregation was determined by multiple electrode aggregometry after stimulation with adenosine diphosphate (ADP) in the maintenance phase of treatment with prasugrel or ticagrelor. Only 3% of patients in the prasugrel group and 2% of study participants in the ticagrelor group had high on treatment platelet reactivity (HTPR). The majority of patients displayed low on treatment platelet reactivity (LTPR; prasugrel: 69%; ticagrelor: 64%). The pharmacodynamic effect was similar in patients treated with prasugrel and ticagrelor: the median level of ADP-induced platelet aggregation was 15U (interquartile range IQR 9-21U) under prasugrel treatment and 17U (IQR 8-24U) under ticagrelor treatment (p=0.370). In conclusion, our study suggests that there is some degree of variability in ADP-induced platelet aggregation under treatment with prasugrel and ticagrelor.

RESUMO

Wire crossing of a chronic total coronary occlusion (CTO) is time consuming and limited by the amount of contrast agent and time of radiation exposure. Magnetic wire navigation (MWN) might accelerate wire crossing by maintaining a coaxial vessel orientation. This study compares MWN with the conventional approach for recanalization of CTOs. Forty symptomatic patients with CTO were randomised to MWN (n = 20) or conventional approach (n = 20) for antegrade crossing of the occlusion. In the intention-to-treat analysis, MWN showed a shorter crossing time (412 versus 1131 s; p = 0.001), and, consequently, lower usage of contrast agent (primary endpoint 42 versus 116 ml; p = 0.01), and lower radiation exposure (dose-area product: 29 versus 80 Gy*cm(2); p = 0.002) during wire crossing compared to the conventional approach. Accordingly, in the per-protocol analysis, the wire-crossing rate was, in trend, higher using the conventional approach (17 of 31) compared to MWN (9 of 28; p = 0.08). The use of MWN for revascularisation of CTOs is feasible and reduces crossing time, use of contrast agent, and radiation exposure. However, due to a broader selection of wires, the conventional approach enables wire crossing in cases failed by MWN and seems to be the more successful choice.

RESUMO

This study assessed whether the presence of tetralogy of Fallot (TOF) affects fetal lung development and whether these fetuses are at risk of pulmonary hypoplasia (PH). Furthermore, we investigated whether the degree of the concomitant pulmonary valve (PV) stenosis or a stenosis in the branch pulmonary arteries correlates with the fetal lung volume. Lung volumetry was performed in 16 fetuses with TOF who underwent MRI between gestational weeks 21 and 35 and in 22 controls. Fetal biometric data and the diameters of the PVs were evaluated by ultrasound. PV and branch pulmonary artery diameters were standardized (z-scores), and fetal lung volume/fetal body weight (FLV/FBW) ratios (ml/g) were calculated. The mean FLV/FBW ratio (0.031 ± 0.009 ml/g) in the TOF group was statistically significantly lower than in the control group (0.041 ± 0.009 ml/g; P = 0.003). None of the fetuses with TOF met the criterion for PH. FLV did not correlate with the degree of PV stenosis, but rather with the presence of a significant stenosis in at least one branch pulmonary artery. The presence of TOF moderately affects fetal lung growth, which is apparently not dependent on the degree of the PV stenosis. However, only an additional stenosis in at least one branch pulmonary artery was associated with a small FLV, but not with PH. Thus, reduced pulmonary blood flow may be offset by additional factors, such as the ability to establish a sufficient collateral system and to alter structural vascular size and, thus, pulmonary vascular resistance.

RESUMO

AIMS: Natriuretic peptide-guided (NP-guided) treatment of heart failure has been tested against standard clinically guided care in multiple studies, but findings have been limited by study size. We sought to perform an individual patient data meta-analysis to evaluate the effect of NP-guided treatment of heart failure on all-cause mortality. METHODS AND RESULTS: Eligible randomized clinical trials were identified from searches of Medline and EMBASE databases and the Cochrane Clinical Trials Register. The primary pre-specified outcome, all-cause mortality was tested using a Cox proportional hazards regression model that included study of origin, age (<75 or ≥75 years), and left ventricular ejection fraction (LVEF, ≤45 or >45%) as covariates. Secondary endpoints included heart failure or cardiovascular hospitalization. Of 11 eligible studies, 9 provided individual patient data and 2 aggregate data. For the primary endpoint individual data from 2000 patients were included, 994 randomized to clinically guided care and 1006 to NP-guided care. All-cause mortality was significantly reduced by NP-guided treatment [hazard ratio = 0.62 (0.45-0.86); P = 0.004] with no heterogeneity between studies or interaction with LVEF. The survival benefit from NP-guided therapy was seen in younger (<75 years) patients [0.62 (0.45-0.85); P = 0.004] but not older (≥75 years) patients [0.98 (0.75-1.27); P = 0.96]. Hospitalization due to heart failure [0.80 (0.67-0.94); P = 0.009] or cardiovascular disease [0.82 (0.67-0.99); P = 0.048] was significantly lower in NP-guided patients with no heterogeneity between studies and no interaction with age or LVEF. CONCLUSION: Natriuretic peptide-guided treatment of heart failure reduces all-cause mortality in patients aged <75 years and overall reduces heart failure and cardiovascular hospitalization.

RESUMO

BACKGROUND: Clinical management of patients with angina and no obstructive coronary artery disease (ANOCA) is still challenging. This scenario affects up to 50% of patients undergoing diagnostic coronary angiography due to suspected coronary artery disease. Many patients report a long and debilitating history before adequate diagnostics and management are initiated. OBJECTIVES: This article describes the current recommendations for diagnostic assessments and treatment in patients with ANOCA. Focus is placed on invasive diagnostics in the catheter laboratory, pharmacological/interventional treatment as well as the patient journey. RESULTS: In patients with ANOCA, the current European Society of Cardiology (ESC) guidelines suggest that invasive assessments using acetylcholine and adenosine for the diagnosis of an underlying coronary vasomotor disorder should be considered. Acetylcholine is used to diagnose coronary spasm, whereas adenosine is used in conjunction with a wire-based assessment for the measurement of coronary flow reserve and microvascular resistance. The invasive assessments allow the determination of what are referred to as endotypes (coronary spasm, impaired coronary flow reserve, enhanced microvascular resistance or a combination thereof). Establishing a diagnosis is helpful to: (a) initiate targeted treatment to improve quality of life, (b) reassure the patient that a cardiac cause is found and (c) to assess individual prognosis. CONCLUSIONS: Currently, patients with ANOCA are often not adequately managed. Referral to specialised centres is recommended to prevent long and debilitating patient histories until expertise in diagnosis and treatment becomes more widespread.

RESUMO

INTRODUCTION: Percutaneous coronary intervention is a well-established revascularization strategy for patients with coronary artery disease. Recent technical advances such as radial access, third generation drug-eluting stents and highly effective antiplatelet therapy have substantially improved the safety profile of coronary procedures. Despite several practice guidelines and a clear patient preference of early hospital discharge, the percentage of coronary procedures performed in an outpatient setting in Austria remains low, mostly due to safety concerns. METHODS: The aim of this consensus statement is to provide a practical framework for the safe and effective implementation of coronary outpatient clinics in Austria. Based on a structured literature review and an in-depth analysis of available practice guidelines a consensus statement was developed and peer-reviewed within the working group of interventional cardiology (AGIK) of the Austrian Society of Cardiology. RESULTS: Based on the available literature same-day discharge coronary procedures show a favorable safety profile with no increase in the risk of major adverse events compared to an overnight stay. This document provides a detailed consensus in various clinical settings. The most important prerequisite for same-day discharge is, however, adequate selection of suitable patients and a structured peri-interventional and postinterventional management plan. CONCLUSION: Based on the data analysis this consensus document provides detailed practice guidelines for the safe operation of daycare cathlab programs in Austria.

RESUMO

INTRODUCTION: Percutaneous coronary intervention is a well-established revascularization strategy for patients with coronary artery disease. The safety and feasibility of performing these procedures on a same-day discharge basis for selected patients has been studied in a large number of mostly nonrandomized trials. An up to date literature review should focus on trials with radial access, representing the current standard for coronary procedures in Austria and other European countries. METHODS: The aim of this consensus statement is to review the most recent evidence for the safety and feasibility of performing same-day discharge procedures in selected patients. A structured literature search was performed using prespecified search criteria, focusing on trials with radial access procedures. RESULTS: A total of 44 clinical trials and 4 large meta-analyses were retrieved, spanning 21 years of clinical evidence from 2001 to 2022. The outcome data from a wide range of clinical settings were unanimous in showing no negative effect on early (24 h) or late (30 day) major adverse events after same-day discharge coronary procedures. Based on nine prospective trials a comprehensive meta-analysis was compiled. Using 1­month major adverse events data the pooled odds ratio of same-day discharge versus overnight stay procedures was 0.66 (95% confidence interval, CI 0.35-01.24; p = 0.19; I2 0%), indicating a noninferiority in carefully selected patients. CONCLUSION: Outcome data from same-day discharge coronary intervention trials with radial access confirm the robust safety profile showing no increase in the risk of major adverse events compared to overnight stay.

RESUMO

BACKGROUND: Stent thrombosis is a rare but deleterious event. Routine coronary angiography with percutaneous coronary intervention (PCI) is often deferred in the presence of laboratory markers of acute inflammation to prevent complications. The aim of this study was to investigate whether an acute inflammatory state is associated with an increased risk of early stent thrombosis. METHODS AND RESULTS: Within a prospective single-center registry, the association between preprocedural acute inflammatory activation, defined as C-reactive protein plasma levels >50 mg/L or a leukocyte count >12 g/L, and occurrence of early (≤30 days) stent thrombosis was evaluated. In total, 11 327 patients underwent PCI and of those, 6880 patients had laboratory results available. 49.6% of the study population received PCI for an acute coronary syndrome and 50.4% for stable ischemic heart disease. In patients with signs of acute inflammatory activation (24.9%), PCI was associated with a significantly increased risk for stent thrombosis (hazard ratio, 2.89; P<0.00001), independent of age, sex, kidney function, number and type of stents, presence of multivessel disease, choice of P2Y12 inhibitor, and clinical presentation. Elevated laboratory markers of acute inflammation were associated with the occurrence of stent thrombosis in both patients with acute coronary syndrome (hazard ratio, 2.63; P<0.001) and in patients with stable ischemic heart disease (hazard ratio, 3.57; P<0.001). CONCLUSIONS: An acute inflammatory state at the time of PCI was associated with a significantly increased risk of early stent thrombosis. Evidence of acute inflammation should result in deferred PCI in elective patients, while future studies are needed for patients with acute coronary syndrome.

RESUMO

OBJECTIVES: A recent randomized, controlled trial in chronic heart failure patients showed that NT-proBNP-guided, intensive patient management (BMC) on top of multidisciplinary care reduced all-cause mortality and heart failure hospitalizations compared with multidisciplinary care (MC) or usual care (UC). We now performed a cost-utility analysis of these interventions from a payer's perspective. METHODS: Costs related to hospitalizations, ambulatory physician and nurse visits, and NT-proBNP testing for the three management strategies were acquired for both Austria (€) and Canada ($) and combined with the survival and quality of life data from the clinical trial for cost-effectiveness analysis. Data on long-term survival, costs, and quality-adjusted life-years (QALY) were extrapolated for a 20-year time horizon using a Markov model, which simulated the progression of disease through beta-blocker use, hospitalizations, and mortality. RESULTS: BMC was the most cost-effective strategy as it was dominant (cost-saving with improved health outcome) over both MC and UC based on both Austrian and Canadian costs. Incremental cost-effectiveness ratios for MC relative to UC were €3,746 and $5,554 per QALY gained for Austrian and Canadian costs, respectively. The probabilities for BMC being the most cost-effective strategy were 92 percent at a threshold value of Austrian €40,000 and 93 percent at a threshold value of Canadian $50,000. CONCLUSIONS: NT-proBNP-guided, intensive HF patient management in addition to multidisciplinary care not only reduces death and hospitalization but also proves to be cost-effective.

RESUMO

OBJECTIVES: This study investigates the relationship between socioeconomic environment (SEE) and survival after ST-segment elevation myocardial infarction (STEMI) separately for women and men in the City of Vienna, Austria. DESIGN: Hospital-based observational data of STEMI patients are linked with district-level information on SEE and the mortality register, enabling survival analyses with a 19-year follow-up (2000-2018). SETTING: The analysis is set at the main tertiary care hospital of the City of Vienna. On weekends, it is the only hospital in charge of treating STEMIs and thus provides representative data for the Viennese population. PARTICIPANTS: The study comprises a total of 1481 patients with STEMI, including women and men aged 24-94 years. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome measures are age at STEMI and age at death. We further distinguish between deaths from coronary artery disease (CAD), deaths from acute coronary syndrome (ACS), and other causes of death. SEE is proxied via mean individual gross income from employment in each municipal district. RESULTS: Results are based on Kaplan-Meier survival probability estimates, Cox proportional hazard regressions and competing risk models, always using age as the time scale. Descriptive findings suggest a socioeconomic gradient in the age at death after STEMI. This finding is, however, not supported by the regression results. Female patients with STEMI have better survival outcomes, but only for deaths related to CAD (HR: 0.668, 95% CIs 0.452 to 0.985) and other causes of deaths (HR: 0.627, 95% CIs 0.444 to 0.884), and not for deaths from the more acute ACS. CONCLUSIONS: Additional research is necessary to further disentangle the interaction between SEE and age at STEMI, as our findings suggest that individuals from poorer districts have STEMI at younger ages, which indicates vulnerability in regard to health conditions in these neighbourhoods.

RESUMO

BACKGROUND: Supplementation with 1 g/d omega-3-polyunsaturated fatty acids (n3-PUFAs) demonstrated a small survival advantage in patients with chronic heart failure (CHF) in the GISSI-HF trial. However, a dose-efficacy relationship was postulated for the beneficial effects of n3-PUFA before. Therefore, we evaluated dose-dependent effects of n3-PUFA in patients with severe CHF. METHODS: In a double-blind, randomized, controlled pilot trial, 43 patients with severe, nonischemic heart failure received 1 g/d n3-PUFA (n = 14), 4 g/d n3-PUFA (n = 13), or placebo (n = 16) for 3 months. Changes in left ventricular ejection fraction (LVEF), flow-mediated vasodilation, plasma high-sensitive interleukin 6 and high-sensitive tumor necrosis factor α, and exercise peak oxygen consumption were assessed. RESULTS: Left ventricular ejection fraction increased in a dose-dependent manner (P = .01 for linear trend) in the 4 (baseline vs 3 months [mean ± SD]: 24% ± 7% vs 29% ± 8%, P = .005) and 1 g/d treatment groups (24% ± 8% vs 27% ± 8%, P = .02). Flow-mediated vasodilation increased significantly with high-dose 4 g/d n3-PUFA (8.4% ± 4.8% vs 11.6% ± 7.0%, P = .01) but only trendwise with low-dose 1 g/d (8.3% ± 5.3% vs 10.2% ± 4.3%, P = .07). Interleukin 6 significantly decreased with 4 g/d n3-PUFA (3.0 ± 2.9 pg/mL vs 0.7 ± 0.8 pg/mL, P = .03) but only trendwise with 1 g/d (4.5 ± 6.6 pg/mL to 1.6 ± 2.1 pg/mL, P = .1). High-sensitive tumor necrosis factor α decreased trendwise with 4 g/d n3-PUFA but remained unchanged with 1 g/d. In patients with maximal exercise effort, only 4 g/d increased the peak oxygen consumption. No changes in any investigated parameters were noted with placebo. CONCLUSION: Treatment with n3-PUFA for 3 months exerts a dose-dependent increase of LVEF in patients with CHF. In parallel, a significant improvement of endothelial function and decrease of interleukin 6 is found with high-dose n3-PUFA intervention.

RESUMO

BACKGROUND: Heart failure management programmes have been shown to reduce re-hospitalizations. We recently investigated a new disease management programme comparing usual care (UC) to home-based nurse care (HNC) and a HNC group in which decision-making was based on NT-proBNP levels (BNC). As re-hospitalization is the main contributing economic factor in heart failure expenditures, we hypothesized that this programme might be able to reduce costs and could be conducted cost effectively compared to UC. METHODS: One hundred and ninety congestive heart failure patients, who were included in a randomized trial to receive UC, HNC or BNC at discharge, were analysed in a cost-effectiveness model. Different models were applied to perform analysis of all medical costs, and the costs per year survived were chosen as an effectiveness parameter. RESULTS: Per patient costs because of heart failure treatment in the UC and the BNC group were € 7109 ± 11,687 and € 2991 ± 4885 (P=0·027), respectively. Corrected for death as a competing risk, the costs in the UC group were € 7893 ± 11,734 and were reduced by BNC to €3148 ± 4949 (P=0·012). Considering costs because of all-cause re-hospitalizations, calculated costs per year survived after discharge were € 19,694 ± 26,754 for UC, € 14,262 ± 25 330 for HNC (P > 0·05) and € 8784 ± 14,728 for BNC (t-test-based contrast P=0·015). In all models calculated, HNC was cost neutral. CONCLUSIONS: NT-BNP-guided heart failure specialist care in addition to home-based nurse care is cost effective and cheaper than standard care, whereas HNC is cost neutral.

RESUMO

As advanced heart failure (HF) with elevated NT-proBNP is characterized by an activated coagulation system, coronary events clinically noticed as sudden or HF death may be more common after treatment with first- compared to newer-generation DES. Our study evaluates (1) if patients with left ventricular dysfunction (LVSD) who underwent percutaneous coronary intervention have a better survival with first- or newer-generation DES, and (2) if the survival benefit is predicted by NT-proBNP. Our observational study evaluated patients with LVSD who were registered in the coronary catheter laboratory database of the Medical University of Vienna. Multivariate Cox regression analyses tested an interaction in the risk of death between those with lower or elevated NT-proBNP levels and the stent-generation. The relative risk of newer- compared to first-generation DES as reference was calculated for patients with low and elevated NT-proBNP levels. In 340 patients (178 newer- and 162 first-generation DES) stent-generation and NT-proBNP were independent predictors of death. When the stent-generation*NTproBNP interaction was forced into a Cox regression model, this term independently predicted death. The relative risk of first- compared to newer-generation DES was similar in patients with lower NT-proBNP (HR 1.02, 95% CI 0.95-1.10, p = 0.560), but was higher in patients with elevated NT-proBNP (HR 1.06, 95% CI 1.01-1.10, p = 0.020). Death is associated to stent-generation. NT-proBNP is a predictor for the stent generation used: elevated levels demonstrated a higher mortality risk when using first- compared to newer-generation DES, while lower levels showed a similar risk when using either DES-generation.

RESUMO

This position statement is an update to the 2011 consensus statement of the Austrian Society of Cardiology (ÖKG) and the Austrian Society of Cardiac Surgery (ÖGTHG) for transfemoral transcatheter aortic valve implantation.Due to a number of recently published studies, broadening of indications and recommendations of medical societies and our own national developments, the ÖKG and the ÖGHTG wish to combine the 2017 ESC/EACTS guidelines for the management of valvular heart disease with a national position paper and to focus on certain details for the application in Austria. Thus, this position statement serves as a supplement and further interpretation of the international guidelines.
