RESUMO

AIMS: The aim of this study was to assess the prevalence of abnormal liver function tests (LFTs) and the associated clinical profile and outcome(s) in acute decompensated heart failure (ADHF) patients. Alteration in LFTs is a recognized feature of ADHF, but prevalence and outcomes data from a broad contemporary cohort of ADHF are scarce and the mechanism(s) of ADHF-induced cholestasis is unknown. METHODS AND RESULTS: We conducted a post hoc analysis of SURVIVE, a large clinical trial including ADHF patients treated with levosimendan or dobutamine. All LFTs were available in 1134 patients at baseline. Abnormal LFTs were seen in 46% of ADHF patients: isolated abnormal alkaline phosphatase (AP) was noted in 11%, isolated abnormal transaminases in 26%, and a combination of abnormal AP and transaminases in 9%. Abnormal AP was associated with marked signs of systemic congestion and elevated right-sided filling pressure. Abnormal AP had no relationship with 31-day mortality but was associated with worse 180-day mortality (23.5 vs. 34.9%, P = 0.001 vs. patients with normal AP). Abnormal transaminases were associated with clinical signs of hypoperfusion and with greater 31-day and 180-day mortality compared with normal transaminase profiles (17.6 vs. 8.4% and 31.6 vs. 22.4%, respectively; both P < 0.001). There was no additive value of abnormal AP plus abnormal transaminase on a long-term outcome. CONCLUSION: Abnormal LFTs were present in about a half of patients presenting with ADHF treated with inotropes. Abnormal AP and abnormal transaminases were associated with specific clinical, biological, and prognostic features, including a short-term overmortality with increased transaminases but not with biological signs of cholestasis, in ADHF patients.

RESUMO

Aging is a fundamental biological process characterized by a progressive decline in physiological functions and an increased susceptibility to diseases. Understanding aging at the molecular level is crucial for developing interventions that could delay or reverse its effects. This review explores the integration of machine learning (ML) with multi-omics technologies-including genomics, transcriptomics, epigenomics, proteomics, and metabolomics-in studying the molecular hallmarks of aging to develop personalized medicine interventions. These hallmarks include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, disabled macroautophagy, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, chronic inflammation, and dysbiosis. Using ML to analyze big and complex datasets helps uncover detailed molecular interactions and pathways that play a role in aging. The advances of ML can facilitate the discovery of biomarkers and therapeutic targets, offering insights into personalized anti-aging strategies. With these developments, the future points toward a better understanding of the aging process, aiming ultimately to promote healthy aging and extend life expectancy.

RESUMO

Population aging is a global phenomenon driving research focus toward preventing and managing age-related disorders. Functional hypogonadism (FH) has been defined as the combination of low testosterone levels, typically serum total testosterone below 300-350 ng/dL, together with manifestations of hypogonadism, in the absence of an intrinsic pathology of the hypothalamic-pituitary-testicular (HPT) axis. It is usually seen in middle-aged or elderly males as a product of aging and multimorbidity. This age-related decline in testosterone levels has been associated with numerous adverse outcomes. Testosterone therapy (TTh) is the mainstay of treatment for organic hypogonadism with an identifiable intrinsic pathology of the HPT axis. Current guidelines generally make weak recommendations for TTh in patients with FH, mostly in the presence of sexual dysfunction. Concerns about long-term safety have historically limited TTh use in middle-aged and elderly males with FH. However, recent randomized controlled trials and meta-analyses have demonstrated safe long-term outcomes regarding prostatic and cardiovascular health, together with decreases in all-cause mortality and improvements in various domains, including sexual function, body composition, physical strength, bone density, and hematopoiesis. Furthermore, there are numerous insightful studies suggesting additional benefits of TTh, for instance in cardio-renal-metabolic conditions. Specifically, future trials should investigate the role of TTh in improving symptoms and prognosis in various clinical contexts, including sarcopenia, frailty, dyslipidemia, arterial hypertension, diabetes mellitus, fracture risk, heart failure, stable angina, chronic kidney disease, mood disorders, and cognitive dysfunction.

RESUMO

OBJECTIVE: This nationwide study aims to analyze mortality trends for all individual causes in Greece from 2001 to 2020, with a specific focus on 2020, a year influenced by the COVID-19 pandemic. As Greece is the fastest-aging country in Europe, the study's findings can be generalized to other aging societies, guiding the reevaluation of global health policies. METHODS: Data on the population and the number of deaths were retrieved from the Hellenic Statistical Authority. We calculated age-standardized mortality rates (ASMR) and cause-specific mortality rates by sex in three age groups (0-64, 65-79, and 80+ years) from 2001 to 2020. Proportional mortality rates for 2020 were determined. Statistical analysis used generalized linear models with Python Programming Language. RESULTS: From 2001 to 2020, the ASMR of cardiovascular diseases (CVD) decreased by 42.7% (p < 0.0001), with declines in most sub-causes, except for hypertensive diseases, which increased by 2.8-fold (p < 0.0001). In 2020, the proportional mortality rates of the three leading causes were 34.9% for CVD, 23.5% for neoplasms, and 9.6% for respiratory diseases (RD). In 2020, CVD were the leading cause of death among individuals aged 80+ years (39.3%), while neoplasms were the leading cause among those aged 0-79 years (37.7%). Among cardiovascular sub-causes, cerebrovascular diseases were predominant in the 80+ year age group (30.3%), while ischemic heart diseases were most prevalent among those aged 0-79 years (up to 60.0%). CONCLUSIONS: The global phenomenon of population aging necessitates a reframing of health policies in our aging societies, focusing on diseases with either a high mortality burden, such as CVD, neoplasms, and RD, or those experiencing increasing trends, such as hypertensive diseases.

RESUMO

This study investigates the forecasting of cardiovascular mortality trends in Greece's elderly population. Utilizing mortality data from 2001 to 2020, we employ two forecasting models: the Autoregressive Integrated Moving Average (ARIMA) and Facebook's Prophet model. Our study evaluates the efficacy of these models in predicting cardiovascular mortality trends over 2020-2030. The ARIMA model showcased predictive accuracy for the general and male population within the 65-79 age group, whereas the Prophet model provided better forecasts for females in the same age bracket. Our findings emphasize the need for adaptive forecasting tools that accommodate demographic-specific characteristics and highlight the role of advanced statistical methods in health policy planning.

RESUMO

BACKGROUND: New-onset postoperative atrial fibrillation (POAF) after coronary artery bypass surgery (CABG) occurs with an incidence of 20-40%. The clinical relevance of POAF remains a concern, and the need for further studies regarding the clinical management of POAF is necessary. AIM: The AFRODITE study, a prospective multicenter cohort study, had as its primary endpoint the evaluation of AF recurrence in patients post CABG over a one-year period. METHODS: Two hundred twenty-eight patients aged >50 years who underwent isolated CABG were included in the study. Patients were stratified into two groups, POAF and non-POAF, and followed for 12 months for AF recurrence, hospitalizations, and death. RESULTS: Two hundred twenty-eight patients (mean age 67 years, 88.6% male) were included in the study. 28.5% of patients experienced at least one episode of POAF during index hospitalization (POAF group) and were compared with the non-POAF group (n = 163). Multivariate stepwise logistic regression analysis showed that the strongest prognostic parameter for POAF was the CHA2DS2-VASc score (odds ratio = 1.61, p < 0.001). POAF patients had a worse in-hospital outcome, but the incidence of long-term AF recurrence was not statistically different (3.6% vs. 4.8%, p = 0.9). CONCLUSION: Interestingly, a one-year prospective follow-up of patients in the study did not reveal significant differences between POAF and non-POAF patients. A notable finding was that patients with a higher CHA2DS2-VASc score were more likely to develop POAF.

RESUMO

Acute heart failure (AHF) represents a broad spectrum of disease states, resulting from the interaction between an acute precipitant and a patient's underlying cardiac substrate and comorbidities. Valvular heart disease (VHD) is frequently associated with AHF. AHF may result from several precipitants that add an acute haemodynamic stress superimposed on a chronic valvular lesion or may occur as a consequence of a new significant valvular lesion. Regardless of the mechanism, clinical presentation may vary from acute decompensated heart failure to cardiogenic shock. Assessing the severity of VHD as well as the correlation between VHD severity and symptoms may be difficult in patients with AHF because of the rapid variation in loading conditions, concomitant destabilization of the associated comorbidities and the presence of combined valvular lesions. Evidence-based interventions targeting VHD in settings of AHF have yet to be identified, as patients with severe VHD are often excluded from randomized trials in AHF, so results from these trials do not generalize to those with VHD. Furthermore, there are not rigorously conducted randomized controlled trials in the setting of VHD and AHF, most of the data coming from observational studies. Thus, distinct to chronic settings, current guidelines are very elusive when patients with severe VHD present with AHF, and a clear-cut strategy could not be yet defined. Given the paucity of evidence in this subset of AHF patients, the aim of this scientific statement is to describe the epidemiology, pathophysiology, and overall treatment approach for patients with VHD who present with AHF.

RESUMO

BACKGROUND: Depression is a common comorbid condition in patients with chronic heart failure (CHF). This pilot study investigated the plasma levels of oxidative stress markers in depressed CHF patients as well as the effects of antidepressant treatment with sertraline on these markers in the same patient population. METHODS AND RESULTS: Patients with positive depression screening [Beck Depression Inventory (BDI) score >10 and/or Zung Self-Rating Depression Scale >40] underwent a psychiatric interview. Patients newly diagnosed as depressed received pharmacologic treatment with sertraline for 3 months (arm A) and were compared with those who did not comply with the antidepressant treatment (arm B). Markers of oxidative stress [malondialdehyde (MDA) and protein carbonyls (PC)], and nitrosative stress [nitrotyrosine (NT)] were assessed at baseline and 3 months later. Fifty-two out of 254 screened hospitalized CHF patients were diagnosed as depressed. Depressed patients had significantly higher levels of MDA compared with age- and gender-matched nondepressed patients (n = 40; 3.2 ± 2.0 vs 2.8 ± 3.8 µmol/L; P = .02). Twenty-eight patients received sertraline (arm A), and 24 refused to receive antidepressant treatment on the top of optimal heart failure treatment (arm B). Although baseline levels of MDA and PC in arm A and arm B did not differ significantly (P > .05), arm A patients demonstrated a significant reduction in MDA (F = 4.657; P = .037) and arm B patients demonstrated no change after 3 months. Regarding the examined scores, arm A patients had a decrease in BDI score (28 ± 11 vs 21 ± 13; P = .008), and arm B patients had no change in BDI score at follow-up (P > .05). Arm A had an increase in 6-minute walking distance (291 ± 110 vs 361 ± 87 m; P = .02), and arm B experienced no change (P > .05). CONCLUSIONS: Increased oxidative stress may play a critical role in the pathophysiology of depression in CHF. Treatment with sertraline improves depressive symptoms and reduces plasma markers of oxidative stress in depressed CHF patients.

RESUMO

One method for detecting radiotherapy treatment errors is to capture the exit dose using an electronic portal imaging device. In comparison with a baseline integrated image, subsequent fractions can be compared and differences in images suggest a difference in the radiation treatment delivered. The aim of this work was to assess the sensitivity of a commercial software PerFRACTION in detecting such differences, arising from three possible sources: (i) changes in the radiation beam or EPID position; (ii) changes in the patient position; and (iii) changes in the patient anatomy. By systematically introducing errors, PerFRACTION was shown to be very sensitive to changes in the radiation beam. Variation in the beam output could be detected within 0.3%, field size within 0.4 mm, collimator rotation within 0.3° and MLC positioning could be verified to within 0.1 mm. EPID misalignment could be detected within 0.3 mm. PerFRACTION was able to detect the mispositioning of an anthropomorphic phantom by 3 mm with static beams, however there was a relative dependency between the patient geometry and the direction of the shift. VMAT beams were less sensitive to patient misalignments, with a shift of 10 mm only detectable once a strict criterion of 1% dose difference was applied. In another simulated scenario PerFRACTION was also able to detect a weight loss equivalent to a 5 mm change in patient separation in VMAT plans and 10 mm in conformal plans. This work showed that the PerFRACTION software could be relied upon to detect potential radiotherapy treatment errors, arising from a variety of sources.

RESUMO

Sixty inflammatory bowel disease (IBD) patients (45 Crohn disease and 15 ulcerative colitis, 40 ± 13 years, 53% male) were examined at baseline and 4 months after intervention (surgical (35 patients) or anti-TNFa treatment (25 patients)). IBD severity, using Mayo score, Harvey-Bradshaw Index (HBI) and biomarkers, was correlated with cardiovascular markers. At baseline, the disease severity, the white blood cells (WBC) values and the reducing power (RP) were significantly correlated with the aortic pulse wave velocity (PWV) (r = 0.4, r = 0.44 and r = 0.48, p < 0.05) and the lateral mitral E' velocity (r = 0.35, p < 0.05 and r = 0.3, p < 0.05). Four months after intervention, there was a reduction of WBC (1962.8/mm3 ± 0.425/mm3, p < 0.001), C-reactive protein (CRP) (8.1 mg/L ± 1.7 mg/L, p < 0.001), malondialdehyde (MDA) (0.81 nmol/mg ± 0.37, p < 0.05) and glycocalyx perfused boundary region (PBR 5-25) (0.24 µm ± 0.05 µm, p < 0.01). Moreover, the brachial flow mediated dilatation (FMD), the coronary flow reserve (CFR) and the left ventricle global longitudinal strain (LV GLS) were significantly improved for both groups (4.5% ± 0.9%, 0.55 ± 0.08, 1.4% ± 0.35%, p < 0.01), while a more significant improvement of PWV/GLS was noticed in the anti-TNFa group. IBD severity is associated with vascular endothelial, cardiac diastolic, and coronary microcirculatory dysfunction. The systemic inflammatory inhibition and the local surgical intervention lead to significant improvement in endothelial function, coronary microcirculation and myocardial deformation.

RESUMO

Controlled pulmonary drug delivery systems employing non-spherical particles as drug carriers attract considerable attention nowadays. Such anisotropic morphologies may travel deeper into the lung airways, thus enabling the efficient accumulation of therapeutic compounds at the point of interest and subsequently their sustained release. This study focuses on the fabrication of electrospun superparamagnetic polymer-based biodegradable microrods consisting of poly(l-lactide) (PLLA), polyethylene oxide (PEO) and oleic acid-coated magnetite nanoparticles (OA·Fe3O4). The production of magnetite-free (0% wt. OA·Fe3O4) and magnetite-loaded (50% and 70% wt. Fe3O4) microrods was realized upon subjecting the as-prepared electrospun fibers to UV irradiation, followed by sonication. Moreover, drug-loaded microrods were fabricated incorporating methyl 4-hydroxybenzoate (MHB) as a model pharmaceutical compound and the drug release profile from both, the drug-loaded membranes and the corresponding microrods was investigated in aqueous media. In addition, the magnetic properties of the produced materials were exploited for remote induction of hyperthermia under AC magnetic field, while the possibility to reduce transport losses and enhance the targeted delivery to lower airways by manipulation of the airborne microrods by DC magnetic field was also demonstrated.

RESUMO

Inflammatory bowel diseases (IBD), largely represented by Crohn's disease (CD) and ulcerative colitis (UC), alter gastrointestinal physiology and mucosal immunity through a complex inflammatory process. These diseases can lead to significant arterial endothelial dysfunction. There is also evidence linking IBD with a modification of cardiac structure and function. A growing body of research has associated IBD with an acceleration of arterial stiffness and atherosclerosis and an increased risk of cardiovascular (CV) morbidity and mortality. The focus of this review is two-fold. Firstly, the literature on IBD in relation to CV dysfunction was evaluated (mainly based on 25 relevant surveys carried out between 2005 and 2018). The vast majority of these studies support a significant association of IBD with a deterioration in CV function. Secondly, the literature available regarding the effect of IBD treatment on CV dysfunction was considered based on studies published between 2007 and 2018. This literature search suggests that IBD treatment may have the potential to ameliorate CV dysfunction resulting in CV benefits. This review will analyse the literature as well as consider emerging research perspectives regarding how IBD treatment could improve CV dysfunction.

RESUMO

The perception that women represent a low-risk population for cardiovascular (CV) disease (CVD) needs to be reconsidered. Starting from risk factors, women are more likely to be susceptible to unhealthy behaviors and risk factors that have different impact on CV morbidity and mortality as compared to men. Despite the large body of evidence as regards the effect of lifestyle factors on the CVD onset, the gender-specific effect of traditional and non-traditional risk factors on the prognosis of patients with already established CVD has not been well investigated and understood. Furthermore, CVD in women is often misdiagnosed, underestimated, and undertreated. Women also experience hormonal changes from adolescence till elder life that affect CV physiology. Unfortunately, in most of the clinical trials women are underrepresented, leading to the limited knowledge of CV and systemic impact effects of several treatment modalities on women's health. Thus, in this consensus, a group of female cardiologists from the Hellenic Society of Cardiology presents the special features of CVD in women: the different needs in primary and secondary prevention, as well as therapeutic strategies that may be implemented in daily clinical practice to eliminate underestimation and undertreatment of CVD in the female population.

RESUMO

Cardiogenic shock (CS) is a complex multifactorial clinical syndrome with extremely high mortality, developing as a continuum, and progressing from the initial insult (underlying cause) to the subsequent occurrence of organ failure and death. There is a large spectrum of CS presentations resulting from the interaction between an acute cardiac insult and a patient's underlying cardiac and overall medical condition. Phenotyping patients with CS may have clinical impact on management because classification would support initiation of appropriate therapies. CS management should consider appropriate organization of the health care services, and therapies must be given to the appropriately selected patients, in a timely manner, whilst avoiding iatrogenic harm. Although several consensus-driven algorithms have been proposed, CS management remains challenging and substantial investments in research and development have not yielded proof of efficacy and safety for most of the therapies tested, and outcome in this condition remains poor. Future studies should consider the identification of the new pathophysiological targets, and high-quality translational research should facilitate incorporation of more targeted interventions in clinical research protocols, aimed to improve individual patient outcomes. Designing outcome clinical trials in CS remains particularly challenging in this critical and very costly scenario in cardiology, but information from these trials is imperiously needed to better inform the guidelines and clinical practice. The goal of this review is to summarize the current knowledge concerning the definition, epidemiology, underlying causes, pathophysiology and management of CS based on important lessons from clinical trials and registries, with a focus on improving in-hospital management.

RESUMO

AIMS: Despite the existence of many studies, there are still limited data about the characteristics of myocarditis in Greece. This led to the creation of the Greek Myocarditis Registry aiming to document the different symptoms and treatment of myocarditis, assess possible prognostic factors, and find similarities and differences to what is already published in literature. This paper is a preliminary descriptive analysis of this Registry. METHODS AND RESULTS: We analysed data for the hospitalization period of all patients included in the Registry from December 2015 until November 2017. Statistics are reported as frequency (%) or median and inter-quartile range (IQR) as appropriate. In total, 146 patients were included; 83.3% of the patients reported an infection during the last 3 months. The most common symptom, regardless of the underlying infection, was chest pain (82.2%) followed by dyspnoea (18.5%), while the most common finding in clinical examination was tachycardia (26.7%). Presentation was more frequent in the winter months. ECG findings were not specific, with the repolarization abnormalities being the most frequent (60.3%). Atrial fibrillation was observed in two patients, both of whom presented with a reduced ventricular systolic function. Left ventricular ejection fraction changed significantly during the hospitalization [55% (IQR: 50-60%) on admission vs. 60% (IQR: 55-60%) on discharge, P = 0.0026]. Cardiac magnetic resonance was performed in 88 patients (61%), revealing mainly subepicardial and midcardial involvement of the lateral wall. Late gadolinium enhancement was present in all patients, while oedema was found in 39 of them. Only 11 patients underwent endomyocardial biopsy. Discharge medication consisted mainly of beta-blockers (71.9%) and angiotensin-converting enzyme inhibitors (41.8%), while 39.7% of the patients were prescribed both. CONCLUSIONS: This preliminary analysis describes the typical presentation of myocarditis patients in Greece. It is a first step in developing a better prognostic model for the course of the disease, which will be completed after the incorporation of the patients' follow-up data.

RESUMO

BACKGROUND: Interleukin-1 increases nitrooxidative stress. We investigated the effects of a human recombinant interleukin-1a receptor antagonist (anakinra) on nitrooxidative stress and vascular and left ventricular function. METHODS AND RESULTS: In an acute, double-blind trial, 23 patients with rheumatoid arthritis were randomized to receive a single injection of anakinra (150 mg s.c.) or placebo and, after 48 hours, the alternative treatment. At baseline and 3 hours after the injection, we assessed (1) coronary flow reserve, aortic distensibility, systolic and diastolic (Em) velocity of the mitral annulus, and E to Em ratio (E/Em) using echocardiography; (2) flow-mediated, endothelium-dependent dilation of the brachial artery; and (3) malondialdehyde, nitrotyrosine, interleukin-6, endothelin-1, and C-reactive protein. In a chronic, nonrandomized trial, 23 patients received anakinra and 19 received prednisolone for 30 days, after which all indices were reassessed. Compared with baseline, there was a greater reduction in malondialdehyde, nitrotyrosine, interleukin-6, and endothelin-1 and a greater increase in flow-mediated dilation, coronary flow reserve, aortic distensibility, systolic velocity of mitral annulus, and E/Em after anakinra than after placebo (malondialdehyde -25% versus 9%; nitrotyrosine -38% versus -11%; interleukin-6 -29% versus 0.9%; endothelin-1 -36% versus -11%; flow-mediated dilation 45% versus -9%; coronary flow reserve 29% versus 4%; and aortic distensibility 45% versus 2%; P<0.05 for all comparisons). After 30 days of treatment, the improvement in biomarkers and in vascular and left ventricular function was greater in the anakinra group than in the prednisolone group (P<0.05). CONCLUSIONS: Interleukin-1 inhibition improves vascular and left ventricular function and is associated with reduction of nitrooxidative stress and endothelin.

RESUMO

AIMS: Clinicians lack a generally accepted means for health status assessment in chronic heart failure (CHF). We investigated the correlation between health status and inflammation burden as well as its long-term prognostic value in CHF outpatients. METHODS AND RESULTS: Kansas City Cardiomyopathy Questionnaires (KCCQ) were completed by 137 CHF outpatients (aged 64+/-12 years, mean ejection fraction 27+/-7%). Inflammatory markers [interleukin (IL)-6, IL-10, TNF-alpha, soluble Fas, Fas ligand, ICAM-1, VCAM-1], plasma B-type natriuretic peptide (BNP), 6 min walk test (6MWT), Zung self-rating depression scale, and Beck Depression Inventory were also assessed. Patients were followed for major cardiovascular events (death or hospitalization for disease progression) for up to 250 days. Patients with worse KCCQ-summary (KCCQ-s<50) score had lower 6MWT (P<0.05), and higher BNP (P<0.05) and pro-inflammatory markers (P<0.05) than those with KCCQ-s>or=50. Worse health status was also associated with shorter event-free survival (115+/-12 days for KCCQ-s<50 vs. 214+/-15 days for KCCQ-s>or=50, P=0.0179). Separating patients according KCCQ-functional score (KCCQ-f, cut-off 50) showed similar results. In multivariate Cox regression analysis, only LVEF (HR=0.637, 95% CI 0.450-0.900, P=0.011) and KCCQ-f (HR=0.035, 95% CI 0.002-0.824, P=0.037) were independent predictors of event-free survival at 250 days. CONCLUSION: KCCQ-s reflects neurohormonal and inflammatory burden in CHF. Among studied questionnaires, only KCCQ-f is an independent predictor of long-term event-free survival in CHF.

RESUMO

Heart Failure (HF) is a global pandemic with rapidly increasing prevalence. In an attempt to maintain patients well being, the therapeutic interest has expanded to the vicious cycles that confer to HF mortality and morbidity and a number of comorbidities have been targeted. Iron deficiency represents a common comorbid condition that affects outcomes in HF. The treatment of iron deficiency is strongly supported by the cardiologic societies all over the world. Intravenous iron, primarily ferric carboxymaltose, has shown clinical benefit in this setting, irrespective of the anemia status. Practical recommendations though are lacking. In this document, we have tried to cover the practical gap and provide useful details for intravenous iron use.

RESUMO

Inotropes aim at increasing cardiac output by enhancing cardiac contractility. They constitute the third pharmacological pillar in the treatment of patients with decompensated heart failure, the other two being diuretics and vasodilators. Three classes of parenterally administered inotropes are currently indicated for decompensated heart failure, (i) the beta adrenergic agonists, including dopamine and dobutamine and also the catecholamines epinephrine and norepinephrine, (ii) the phosphodiesterase III inhibitor milrinone and (iii) the calcium sensitizer levosimendan. These three families of drugs share some pharmacologic traits, but differ profoundly in many of their pleiotropic effects. Identifying the patients in need of inotropic support and selecting the proper inotrope in each case remain challenging. The present consensus, derived by a panel meeting of experts from 21 countries, aims at addressing this very issue in the setting of both acute and advanced heart failure.

RESUMO

OBJECTIVE: Functional electrical stimulation (FES) improves exercise capacity and endothelial function in chronic heart failure (CHF) patients. This study evaluates the impact of FES on quality of life and emotional stress in patients with moderate to severe CHF. METHODS: Thirty patients with stable CHF (24 men; NYHA class II-III; left ventricular ejection fraction <35%) were randomly assigned (2:1) to a 6-week FES training program (n=20) or placebo (n=10). Questionnaires addressing quality of life [Kansas City Cardiomyopathy Questionnaire (KCCQ), functional and overall], and emotional stress [Zung self-rating depression scale (SDS), Beck Depression Inventory (BDI)], as well as plasma B-type natriuretic peptide (BNP) and 6-min walking distance test (6MWT) were assessed at baseline and after completion of training protocol. RESULTS: A significant improvement in KCCQ functional (F=76.666, p<0.001), KCCQ overall (F =41.508, p<0.001), BDI (F =17.768, p<0.001) and Zung SDS (F =27.098, p<0.001) was observed in the FES group compared to placebo. Patients in the FES group had also a significant increase in 6MWT (F =19.413, p<0.001) and a trend towards reduction in plasma BNP (F =4.252, p=0.053) compared to placebo. CONCLUSION: FES seems to have a beneficial effect on quality of life, exercise capacity and emotional stress in patients with moderate to severe CHF.
