Prognostic Role of Contraindicated Drugs in Hospitalized Patients with Decompensated Heart Failure.

Due to the ageing population, patients often present to the hospital with a high burden of comorbidities and polypharmacy. For patients admitted with decompensated heart failure (HF), the evidence on the effects of contraindicated drugs on long-term mortality is scarce. Therefore, we aimed to investigate the effect of contraindicated medications on outcomes of patients admitted with decompensated HF. We analyzed all consecutive patients from the National Heart Failure Audit admitted to two tertiary centers with acutely decompensated HF between April 2020 and October 2021. We included medication classes listed as contraindicated (class III) in the most recent European and American guidelines on the management of HF. The primary outcome measure was in-hospital mortality. The secondary outcome measure was overall mortality. Overall, 716 patients admitted with acute HF were included. One-fifth (n = 156, 21.8%) were on at least one contraindicated medication at admission. The prevalence of comorbidities was comparable between medication groups. During hospitalization, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with increased in-hospital mortality (29% versus 9%, P = 0.013). On multivariable analyses, NSAID use was independently associated with worse in-hospital mortality (hazard ratio, 6.86; 95% confidence interval, 1.61-25.5; P = 0.005). However, other contraindicated medications were not associated with adverse outcomes. Postdischarge, the use of erythropoietin during admission was associated with increased mortality (54% versus 31%, P = 0.031). NSAID use is associated with increased in-hospital mortality for patients admitted with acute HF. However, inpatient use of other contraindicated medications was not associated with adverse in-hospital outcomes. Further studies are needed to confirm these results in larger and prospective cohorts. SIGNIFICANCE STATEMENT: Use of nonsteroidal anti-inflammatory drugs is associated with a worse in-hospital mortality in patients with decompensated heart failure. The prognostic role of other contraindicated medications remains still uncertain.

Treatment of Iron Deficiency in Heart Failure.

PURPOSE OF REVIEW: Heart failure (HF) is commonly associated with iron deficiency (ID), defined as insufficient levels of iron to meet physiological demands. ID's association with anaemia is well understood but it is increasingly recognised as an important comorbidity in HF, even in the absence of anaemia. This review summarises contemporary evidence for the measurement and treatment of ID, in both HFrEF and HFpEF, and specific HF aetiologies, and highlights important gaps in the evidence-base. RECENT FINDINGS: ID is common among patients with HF and associated with increased morbidity and mortality. Correcting ID in patients with HF can impact upon functional status, exercise tolerance, symptoms, and overall quality of life, irrespective of anaemia status. ID is a modifiable comorbidity in HF. Therefore, recognising and treating ID has emerging therapeutic potential and is important for all clinicians who care for patients with HF to understand the rationale and approach to treatment.

Exploring the prevalence, impact and experience of cardiac cachexia in patients with advanced heart failure and their caregivers: A sequential phased study.

BACKGROUND: Cardiac Cachexia is a wasting syndrome that has a significant impact on patient mortality and quality of life world-wide, although it is poorly understood in clinical practice. AIM: Identify the prevalence of cardiac cachexia in patients with advanced New York Heart Association (NYHA) functional class and explore its impact on patients and caregivers. DESIGN: An exploratory cross-sectional study. The sequential approach had two phases, with phase 1 including 200 patients with NYHA III-IV heart failure assessed for characteristics of cardiac cachexia. Phase 2 focussed on semi-structured interviews with eight cachectic patients and five caregivers to ascertain the impact of the syndrome. SETTING/PARTICIPANTS: Two healthcare trusts within the United Kingdom. RESULTS: Cardiac Cachexia was identified in 30 out of 200 participants, giving a prevalence rate of 15%. People with cachexia had a significantly reduced average weight and anthropometric measures (p < 0.05). Furthermore, individuals with cachexia experienced significantly more fatigue, had greater issues with diet and appetite, reduced physical wellbeing and overall reduced quality of life. C-reactive protein was significantly increased, whilst albumin and red blood cell count were significantly decreased in the cachectic group (p < 0.05). From qualitative data, four key themes were identified: (1) 'Changed relationship with food and eating', (2) 'Not me in the mirror', (3) 'Lack of understanding regarding cachexia' and (4) 'Uncertainty regarding the future'. CONCLUSIONS: Cardiac cachexia has a debilitating effect on patients and caregivers. Future work should focus on establishing a specific definition and clinical pathway to enhance patient and caregiver support.

Cardiovascular Damage in COVID-19: What We Know Two Years Later.

PURPOSE OF THE REVIEW: The Coronavirus disease 2019 (COVID-19) pandemic has profoundly influenced cardiological clinical and basic research in the past two years. In the present review, we summarize the current knowledge on myocardial involvement in COVID-19, providing an overview on the incidence, the pathogenetic mechanisms, and the clinical implications of cardiac injury in this setting. RECENT FINDINGS: The possibility of heart involvement in patients with COVID-19 has received great attention since the beginning of the pandemic. After more than two years, several steps have been taken in understanding the mechanisms and the incidence of cardiac injury during COVID-19 infection. Similarly, studies globally have clarified the implications of co-existing heart disease and COVID-19. Severe COVID-19 infection may be complicated by myocardial injury. To date, a direct damage from the virus has not been demonstrated. The presence of myocardial injury should be systematically assessed for a prognostication purpose and for possible therapeutic implications.

Clozapine-induced myocarditis: electronic health register analysis of incidence, timing, clinical markers and diagnostic accuracy.

BACKGROUND: Clozapine is associated with increased risk of myocarditis. However, many common side-effects of clozapine overlap with the clinical manifestations of myocarditis. As a result, there is uncertainty about which signs, symptoms and investigations are important in distinguishing myocarditis from benign adverse effects of clozapine. Clarity on this issue is important, since missing a diagnosis of myocarditis or discontinuing clozapine unnecessarily may both have devastating consequences. AIMS: To examine the clinical characteristics of clozapine-induced myocarditis and to identify which signs and symptoms distinguish true myocarditis from other clozapine adverse effects. METHOD: A retrospective analysis of the record database for 247 621 patients was performed. A natural language processing algorithm identified the instances of patients in which myocarditis was suspected. The anonymised case notes for the patients of each suspected instance were then manually examined, and those whose instances were ambiguous were referred for an independent assessment by up to three cardiologists. Patients with suspected instances were classified as having confirmed myocarditis, myocarditis ruled out or undetermined. RESULTS: Of 254 instances in 228 patients with suspected myocarditis, 11.4% (n = 29 instances) were confirmed as probable myocarditis. Troponin and C-reactive protein (CRP) had excellent diagnostic value (area under the curve 0.975 and 0.896, respectively), whereas tachycardia was of little diagnostic value. All confirmed instances occurred within 42 days of clozapine initiation. CONCLUSIONS: Suspicion of myocarditis can lead to unnecessary discontinuation of clozapine. The 'critical period' for myocarditis emergence is the first 6 weeks, and clinical signs including tachycardia are of low specificity. Elevated CRP and troponin are the best markers for the need for further evaluation.

Yersinia intussusception: case report and review.

Intussusception is a recognised paediatric presentation in emergency department and primary care settings. The aetiology of intussusception is multifactorial and largely unknown but includes infection in some cases. Yersinia has been the most frequently cited bacterial association in children. Identifying Yersinia affects the role and choice of antibiotics in a child's treatment regimen. This article reports on Australia's first proven case of Yersinia enterocolitica intussusception, and reviews the clinical epidemiology of all known reported cases world-wide.

Australian Paediatric Rheumatology Group standards of care for the management of juvenile idiopathic arthritis.

This standards document outlines accepted standards of management for children, adolescents and young adults with juvenile idiopathic arthritis (JIA) in Australia. This document acknowledges that the chronic inflammatory arthritis conditions (JIA) in childhood are different diseases from inflammatory arthritis in adults and that specific expertise is required in the care of children with arthritis.

A nationwide, population-based study on specialized care for acute heart failure throughout the COVID-19 pandemic.

AIMS: The COVID-19 pandemic disrupted the delivery of care for patients with heart failure (HF), leading to fewer HF hospitalizations and increased mortality. However, nationwide data on quality of care and long-term outcomes across the pandemic are scarce. METHODS AND RESULTS: We used data from the National Heart Failure Audit (NHFA) linked to national records for hospitalization and deaths. We compared pre-COVID (2018-2019), COVID (2020), and late/post-COVID (2021-2022) periods. Data for 227 250 patients admitted to hospital with HF were analysed and grouped according to the admission year and the presence of HF with (HFrEF) or without reduced ejection fraction (non-HFrEF). The median age at admission was 81 years (interquartile range 72-88), 55% were men (n = 125 975), 87% were of white ethnicity (n = 102 805), and 51% had HFrEF (n = 116 990). In-hospital management and specialized cardiology care were maintained throughout the pandemic with an increasing percentage of patients discharged on disease-modifying medications over time (p < 0.001). Long-term outcomes improved over time (hazard ratio [HR] 0.92, 95% confidence interval [CI] 0.90-0.95, p < 0.001), mainly driven by a reduction in cardiovascular death. Receiving specialized cardiology care was associated with better long-term outcomes both for those who had HFrEF (HR 0.79, 95% CI 0.77-0.82, p < 0.001) and for those who had non-HFrEF (HR 0.87, 95% CI 0.85-0.90, p < 0.001). CONCLUSIONS: Despite the disruption of healthcare systems, the clinical characteristics of patients admitted with HF were similar and the overall standard of care was maintained throughout the pandemic. Long-term survival of patients hospitalized with HF continued to improve after COVID-19, especially for HFrEF.
