Inappropriate behaviour is an umbrella term including discrimination, harassment and bullying. This includes both actions and language and can affect any member of the cardiovascular workforce/team. Evidence has suggested that such behaviour is regularly experienced within UK cardiology departments, where inappropriate behaviour may represent longstanding cultural and practice issues within the unit. Inappropriate behaviour has negative effects on the workforce community as a whole, including impacts on recruitment and retention of staff and patient care. While only some members of the cardiology team may be directly impacted by inappropriate behaviour in individual departments, a wider group are significantly impacted as bystanders. As such, improving the culture and professional behaviours within UK cardiology departments is of paramount importance. As a negative workplace culture is felt to be a major driver of inappropriate behaviour, all members of the cardiovascular team have a role to play in ensuring a positive workplace culture is developed. Episodes of inappropriate behaviour should be challenged by cardiovascular team members. Informal feedback may be appropriate where ‘one-off’ episodes of inappropriate behaviour occur, but serious events or repeated behaviour should be escalated following formal human resources protocols.

The subspecialty of cardio-oncology aims to reduce cardiovascular morbidity and mortality in patients with cancer or following cancer treatment. Cancer therapy can lead to a variety of cardiovascular complications, including left ventricular systolic dysfunction, pericardial disease, and valvular heart disease. Echocardiography is a key diagnostic imaging tool in the diagnosis and surveillance for many of these complications. The baseline assessment and subsequent surveillance of patients undergoing treatment with anthracyclines and/or human epidermal growth factor (EGF) receptor (HER) 2-positive targeted treatment (e.g. trastuzumab and pertuzumab) form a significant proportion of cardio-oncology patients undergoing echocardiography. This guideline from the British Society of Echocardiography and British Cardio-Oncology Society outlines a protocol for baseline and surveillance echocardiography of patients undergoing treatment with anthracyclines and/or trastuzumab. The methodology for acquisition of images and the advantages and disadvantages of techniques are discussed. Echocardiographic definitions for considering cancer therapeutics-related cardiac dysfunction are also presented.

OBJECTIVES This study is to determine the management and clinical outcomes of patients investigated with coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFRCT) according to sex.BACKGROUND Women are underdiagnosed with conventional ischemia testing, have lower rates of obstructive coronary artery disease (CAD) at invasive coronary angiography (ICA), yet higher mortality compared to men. Whether FFRCT improves sex-based patient management decisions compared to CCTA alone is unknown.METHODS Subjects with symptoms and CAD on CCTA were enrolled (2015 to 2017). Demographics, symptom status, CCTA anatomy, coronary volume to myocardial mass ratio (V/M), lowest FFRCT values, and management plans were captured. Endpoints included reclassification rate between CCTA and FFRCT management plans, incidence of ICA demonstrating obstructive CAD ($50% stenosis) and revascularization rates.RESULTS A total of 4,737 patients (n = 1,603 females, 33.8%) underwent CCTA and FFRCT. Women were older (age 68 +/- 10 years vs. 65 +/- 10 years; p < 0.0001) with more atypical symptoms (41.5% vs. 33.9%; p < 0.0001). Women had less obstructive CAD (65.4% vs. 74.7%; p < 0.0001) at CCTA, higher FFRCT (0.76 +/- 0.10 vs. 0.73 +/- 0.10; p < 0.0001), and lower likelihood of positive FFRCT

Introduction Women are under-represented in cardiology in the UK (28% of cardiology trainees and 13% of cardiology consultants are female despite women accounting for >50% of medical students). Lack of female role models is one of the commonly cited reasons for the lack of women within the field. Fair representation of female speakers at national cardiology conferences is therefore important to increase the visibility of women within cardiology. We assessed the extent of female representation at UK national cardiology conferences over the last 4 years. Methods We requested the past programmes for annual conferences from 8 national cardiology societies in the UK. The programmes were reviewed and for each chair, panellist, operator and speaker, a binary definition of gender was assigned (female or male). In cases where gender was unclear from the name, the General Medical Council (GMC) register was referred to. For those not on the GMC register, we searched for the individual online. In any remaining cases of ambiguity, we selected the gender most commonly associated with that name. Speakers presenting abstracts were excluded. Results Programmes were obtained from 7 societies (British Cardiovascular Society (BCS), British Cardiovascular Intervention Society (BCIS), British Heart Rhythm Society (BHRS), British and Irish Hypertension Society (BIHS), British Society of Cardiovascular Magnetic Resonance (BSCMR), British Society of Echocardiography (BSE), and British Society for Heart Failure (BSH). A total of 25 annual conferences were analysed. There were a total of 3959 slots; 982 of these were female (25%). Of the 951 chair slots, 224 (24%) were female. There were 3007 speaker/panellist slots, of which 760 (25%) were female. See table 1 below for details. Conclusion There is significant variation in the proportion of female speakers between societies (11-45%). Specialties with the lowest numbers of female consultants had the lowest female representation, however BCS which represents all sub-specialties also had poor female speaker representation. No clear improvement in female numbers occurred from 2017-2020. As part of a drive to facilitate gender equality within cardiology, conference committees need to ensure that speaker panels are gender balanced to enhance visibility of women within the specialty.

Cancer is one of the leading causes of death worldwide. Chemotherapy-induced arrhythmia is a potential complication of treatment that confers increased morbidity and mortality. The relationship between chemotherapeutic agents and arrhythmias is poorly established. Atrial fibrillation, ventricular ectopic beats, and prolonged QTc are the most common arrhythmias suffered by cancer patients undergoing chemotherapy. The treatment of atrial fibrillation in cancer is complicated by complex drug–drug interactions and a lack of evidence guiding practice. Furthermore, the normal risk assessment scores utilized in the decision-making for anticoagulation in the normal population are not validated in the cancer population. Multiple agents are implicated in prolonging the QTc, and this can often have adverse consequences for both the patient and the treatment of their cancer. This can manifest as torsades de pointes and sudden cardiac death. It is advised that, during treatment, oncologists should have close liaison with cardio-oncologists to ensure optimum patient management.

Cardio-oncology is the care of cancer patients with cardiovascular disease. The need for a dedicated subspecialty emerged to address heart failure caused by drugs such as anthracyclines and anti-human epidermal growth factor receptor 2 (HER2) therapies, but over time has expanded into an exciting subspecialty with widening horizons. While still dealing with a lot of commonly recognised toxicities, such as heart failure, hypertension and coronary disease, new and revolutionary cancer therapies have been associated with challenging cardiovascular complications, requiring specialist input to manage effectively. Echocardiography is a key investigation, with advanced techniques such as three-dimensional and strain assessment allowing more accurate diagnosis and earlier detection of subtle changes. Cardiac magnetic resonance and biomarkers are useful adjuncts to aid diagnosis and management. With increasing cancer incidence and improved cancer survival rates, it is important that general cardiologists and physicians are aware of cardiac complications associated with cancer and how to manage them.

The delivery of radiotherapy to patients with a cardiac implantable electronic device (CIED) is not an infrequent event. Consideration of the potential issues for patients is an important part of their care. An overview of CIEDs is provided, including the potential problems encountered and the steps that can be taken to mitigate this risk.

Carcinoid heart disease is a frequent occurrence in patients with carcinoid syndrome and is responsible for substantial morbidity and mortality. The pathophysiology of carcinoid heart disease is poorly understood; however, chronic exposure to excessive circulating serotonin is considered one of the most important contributing factors. Despite recognition, international consensus guidelines specifically addressing the diagnosis and management of carcinoid heart disease are lacking. Furthermore, there is considerable variation in multiple aspects of screening and management of the disease. The aim of these guidelines was to provide succinct, practical advice on the diagnosis and management of carcinoid heart disease as well as its surveillance. Recommendations and proposed algorithms for the investigation, screening, and management have been developed based on an evidence-based review of the published data and on the expert opinion of a multidisciplinary consensus panel consisting of neuroendocrine tumor experts, including oncologists, gastroenterologists, and endocrinologists, in conjunction with cardiologists and cardiothoracic surgeons.

Salmonella is one of the most common pathogens associated with foodborne illness in chickens. Food outbreaks from this pathogen haven’t declined in the past 15 years according to the data from Centers for Disease Control and Prevention. It is our goal to improve food safety monitoring in this area by developing a real time Salmonella detection sensor on food surfaces. Previously, we demonstrated the use of phage C4-22 immobilized onto a rapid magnetoelastic (ME) biosensor for use as a front-line detection ligand to detect all Salmonella enterica serotypes in Tris Buffer Saline (TBS). In this study, by using fluorescent imaging, the phage peptide binding to Salmonella enterica serotype Typhimurium cells is again confirmed. Moreover, we constructed two detection models to evaluate the detection of Salmonella on/in chicken meat using the phage coated ME sensors. In the chicken surface detection method, phage C4-22 sensors demonstrated more than 12 times higher Salmonella binding capacity than the control sensors with no phage for the Salmonella spiked at the concentration of 7.86 × 105 cfu/mm2. In the second model, phage sensors were placed at different depths inside the chicken breast (0.1 cm; 0.5 cm; 1.0 cm below the meat surface) after surface inoculation of Salmonella. The second detection system showed that 23.27%–33% of the inoculated Salmonella cells absorbed inside the chicken breast fillets below 0.1 cm of the surface. The data for direct detection on chicken showed that phage C4-22 ME biosensors bind ultimately when there are high concentrations of Salmonella on the chicken surface. The results also suggest that the phage sensors can detect Salmonella effectively when the bacterial contaminants are absorbed into the chicken, and are not detectable by the surface detection method.

In the UK, 15% of physician trainees are less than full time (LTFT) (25% of female and 3% of male trainees).1 The 2018 British Junior Cardiologists’ Association (BJCA) annual survey identified that approximately 4% of cardiology trainees work LTFT. To explore this further, a survey was sent to LTFT cardiology trainees to identify the challenges they face. Of the estimated 24 LTFT cardiology trainees in the UK, 70% completed the survey. Thirty-one per cent were male, much higher than the proportion of physician LTFT trainees who are male (9%).1 The majority of LTFT trainees are 31–40 years old and are training LTFT in a full-time post (88%). Nearly half of LTFT trainees work 80% of full time. Childcare responsibility is the most common reason for working LTFT (82%). The subspecialty interests of …

Background Neuroendocrine tumours are slow growing tumours known to secrete a variety of vasoactive peptides which give rise to symptoms of the carcinoid syndrome. The diagnosis and monitoring of patients with neuroendocrine tumours is undertaken in many centres using 24 h urinary measurement of 5-hydroxyindoleacetic acid. However, 5-hydroxyindoleacetic acid can also be quantified in plasma and serum. Methods We measured 5-hydroxyindoleacetic acid concentration in 134 paired EDTA plasma and urine samples from 108 patients with known neuroendocrine tumours and 26 healthy volunteers. We also compared 5-hydroxyindoleacetic acid concentrations in paired serum and plasma samples ( n = 63), then analysed paired urine and serum samples ( n = 97). Furthermore, we examined the impact of renal impairment on serum 5-hydroxyindoleacetic acid by analysing 5-hydroxyindoleacetic acid in patients without neuroendocrine tumours in different stages of chronic kidney disease, as indicated by the estimated glomerular filtration rate. Results Plasma and urine 5-hydroxyindoleacetic acid had very similar diagnostic sensitivities and specificities, with areas under the curve on ROC analysis of 0.917 and 0.920, respectively. Serum and plasma 5-hydroxyindoleacetic acid values showed good correlation but serum results demonstrated a positive bias, indicating the necessity for different serum and plasma reference intervals. There was an inverse correlation between estimated glomerular filtration rate and serum 5-hydroxyindoleacetic acid concentration, with 5-hydroxyindoleacetic acid increasing once the estimated glomerular filtration rate falls below 60 mL/min/1.73 m2. Conclusion The measurement of both serum and plasma 5-hydroxyindoleacetic acid can be used for the diagnosis and monitoring of patients with neuroendocrine tumours. Provided renal function is taken into consideration, either of these tests should be incorporated into standard practice as an alternative assay to urinary 5-hydroxyindoleacetic acid.

Objectives: Post-menopausal hot flushes occur due to a reduction in oestrogen production causing thermoregulatory and vascular dysfunction. Exercise training enhances thermoregulatory control of sweating, skin and brain blood flow. We aimed to determine if improving thermoregulatory control and vascular function with exercise training alleviated hot flushes. Methods: Twenty one symptomatic females completed a 7-day hot flush questionnaire and underwent brachial artery flow-mediated dilation and a cardiorespiratory fitness test. Sweat rate and skin blood flow temperature thresholds and sensitivities, and middle cerebral artery velocity (MCAv) was measured during passive heating. Females performed 16-weeks of supervised exercise training or control, and measurements were repeated. Results: There was a greater improvement in cardiorespiratory fitness (4.45 ml•kg-1•min-1 (95% CI: 1.87, 8.16; P=0.04) and reduced hot flush frequency [48 hot flushes•week (39, 56) P

Aims Screening for carcinoid heart disease is an important, yet frequently neglected aspect of the management of patients with neuroendocrine tumours (NETs). Screening is advocated in international guidelines, although recommendations on the modality and frequency are poorly defined. We mapped current practice for the screening and management of carcinoid heart disease in specialist NET centres throughout the UK and Republic of Ireland. Materials and methods Thirty-five NET centres were invited to complete an online questionnaire outlining the size of NET service, patient selection criteria for carcinoid heart disease screening and the modality and frequency of screening. Results Twenty-eight centres responded (80%), representing over 5500 patients. Eleven per cent of centres screen all patients with any NET, 14% screen only patients with midgut NETs, 32% screen all patients with liver metastases and/or carcinoid syndrome and 43% screen all patients with evidence of syndrome or raised urinary/serum/plasma 5-hydroxyindoleacetic acid (5HIAA). The mode of screening included clinical examination, echocardiography and biomarker measurement: 89% of centres carry out echocardiography, ranging from at initial presentation only (24%), periodically without clearly defined intervals (28%), annually (36%) or less than annually (12%); three centres use a scoring system to report their echocardiograms. Fifty per cent of centres utilise biomarkers for screening (chromogranins, plasma/urinary 5HIAA or most commonly N-terminal pro-brain natriuretic peptide) at varying time intervals. Conclusion There is considerable heterogeneity across the UK and Ireland in multiple aspects of screening and management of carcinoid heart disease.

Background: Heart type fatty acid protein (HFABP) is a cytosolic protein released early after acute coronary syndrome (ACS) even in the absence of myocardial necrosis. Objectives: The purpose of this systematic review was to determine whether HFABP levels in patients with suspected, or confirmed ACS, improve risk stratification when added to established means of risk assessment. Methods: We searched Medline, Pubmed and Embase databases from inception to July 2015 to identify prospective studies with suspected or confirmed ACS, who had HFABP measured during the index admission with at least 1 month follow up data. A prognostic event was defined as allcause mortality or acute myocardial infarction (AMI). Results: 7 trials providing data on 6935 patients fulfilled inclusion criteria. There were considerable differences between studies and this was manifest in variation in prognostic impact of elevated HFABP(Odds ratio range 1.2-15.2 for death). All studies demonstrated that HFABP provide unadjusted prognostic information and in only one study this was negated after adjusting for covariates. A combination of both negative troponin and normal HFABP conferred a very low event rate. No study evaluated the incremental value of HFABP beyond that of standard risk scores. Only one study used a high sensitive troponin assay. Conclusion: There was marked heterogeneity in prognostic impact of HFABP in ACS between studies reflecting differences in sampling times and population risk. Prospective studies of suspected ACS with early sampling of HFABP in the era of high sensitivity troponin are necessary to determine the clinical value of HFABP. HFABP should not currently be used clinically as a prognostic marker in patients with suspected ACS.

Background: Carcinoid heart disease is a complication of metastatic neuroendocrine tumours (NETs). We sought to identify factors associated with echocardiographic progression of carcinoid heart disease and death in patients with metastatic NETs. Methods: Patients with advanced non-pancreatic NETs and documented liver metastases and/or carcinoid syndrome underwent prospective serial clinical, biochemical, echocardiographic and radiological assessment. Patients were categorised as carcinoid heart disease progressors, non-progressors or deceased. Multinomial regression was used to assess the univariate association between variables and carcinoid heart disease progression. Results: One hundred and thirty-seven patients were included. Thirteen patients (9%) were progressors, 95 (69%) non-progressors and 29 (21%) patients deceased. Baseline median levels of serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and plasma 5-hydroxyindoleacetic acid (5-HIAA) were significantly higher in the progressors. Every 100 nmol l−1 increase in 5-HIAA yielded a 5% greater odds of disease progression (OR 1.05, 95% CI: 1.01, 1.09; P=0.012) and a 7% greater odds of death (OR 1.07, 95% CI: 1.03, 1.10; P=0.001). A 100 ng l−1 increase in NT-proBNP did not increase the risk of progression, but did increase the risk of death by 11%. Conclusions: The biochemical burden of disease, in particular baseline plasma 5-HIAA concentration, is independently associated with carcinoid heart disease progression and death. Clinical and radiological factors are less useful prognostic indicators of carcinoid heart disease progression and/or death.

BACKGROUND: The term 'metabolically healthy obese (MHO)' is distinguished using body mass index (BMI), yet BMI is a poor index of adiposity. Some epidemiological data suggest that MHO carries a lower risk of cardiovascular disease (CVD) or mortality than being normal weight yet metabolically unhealthy. OBJECTIVES: We aimed to undertake a detailed phenotyping of individuals with MHO by using imaging techniques to examine ectopic fat (visceral and liver fat deposition) and myocardial function. We hypothesised that metabolically unhealthy individuals (irrespective of BMI) would have adverse levels of ectopic fat and myocardial dysfunction compared with MHO individuals. SUBJECTS: Individuals were categorised as non-obese or obese (BMI ⩾30 kg m(-2)) and as metabolically healthy or unhealthy according to the presence or absence of metabolic syndrome. METHODS: Sixty-seven individuals (mean±s.d.: age 49±11 years) underwent measurement of (i) visceral, subcutaneous and liver fat using magnetic resonance imaging and proton magnetic resonance spectroscopy, (ii) components of metabolic syndrome, (iii) cardiorespiratory fitness and (iv) indices of systolic and diastolic function using tissue Doppler echocardiography. RESULTS: Cardiorespiratory fitness was similar between all groups; abdominal and visceral fat was highest in the obese groups. Compared with age- and BMI-matched metabolically healthy counterparts, the unhealthy (lean or obese) individuals had higher liver fat and decreased early diastolic strain rate, early diastolic tissue velocity and systolic strain indicative of subclinical systolic and diastolic dysfunction. The magnitude of dysfunction correlated with the number of components of metabolic syndrome but not with BMI or with the degree of ectopic (visceral or liver) fat deposition. CONCLUSIONS: Myocardial dysfunction appears to be related to poor metabolic health rather than simply BMI or fat mass. These data may partly explain the epidemiological evidence on CVD risk relating to the different obesity phenotypes.

Background: Carcinoid heart disease (CHD) is an important complication of metastatic neuroendocrine disease, requiring regular monitoring to enable intervention prior to right heart failure. We aimed to identify the most appropriate echocardiographic scoring systems for the quantitative assessment of CHD. Methods: In this prospective study conducted between April and October 2012 in two European Neuroendocrine Tumor Society (ENETS) Centres of Excellence, patients with neuroendocrine tumours with liver metastases and/or carcinoid syndrome underwent transthoracic echocardiography and blood sampling for serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and plasma 5-hydroxyindoleacetic acid (5-HIAA). Each patient was assessed according to six echocardiographic scoring systems. The individual scoring systems' feasibility, observer variability, sensitivity, specificity and correlation with the concentration biomarkers were determined. Results: 100 patients were included; 21% had echocardiographic evidence of CHD. All scores discriminated highly between those with/without CHD, with no single score performing significantly better than another. The severity, determined using all of the scoring systems, correlated with the concentration of both biomarkers, but the strongest correlations were seen between the Bhattacharyya score and serum NT-proBNP. Conclusion: All scoring systems are comparable in terms of sensitivity and specificity for the detection of CHD. There is a variation in the feasibility of the scoring systems due to varying complexity of the score components. All scores correlate with NT-proBNP and plasma 5-HIAA. The Westberg score appears to be the most optimal scoring system for use in screening of CHD whereas the more complex scoring systems are more suited to the patient with established disease who may require surgical intervention.

Carcinoid heart disease is a major cause of morbidity and mortality in patients with metastatic neuroendocrine tumours (NETs). Although cases of carcinoid syndrome and severe carcinoid heart disease requiring urgent intervention are well described, many patients with significant carcinoid heart disease may have insidious symptoms or even be asymptomatic. As haemodynamically significant carcinoid heart disease may be clinically silent, specific and individualised considerations must be made as to the most appropriate clinical criteria and time point at which surgical valve replacement should be undertaken in patients with carcinoid heart disease.

PurposeMetastatic neuroendocrine tumors secrete serotonin and other vasoactive substances that are responsible for carcinoid syndrome and carcinoid heart disease. We sought to evaluate the discriminatory utility of diagnostic biomarkers in determining the presence and severity of carcinoid heart disease in patients with metastatic neuroendocrine tumors.Patients and methodsA cross-sectional study of patients with neuroendocrine tumors with documented liver metastases and/or carcinoid syndrome between April 2009-October 2012 in 5 tertiary referral centers. Serum was analyzed for Chromogranin A, Chromogranin B and N-terminal pro Brain Natriuretic Peptide (NT-proBNP). Plasma was analyzed for Neurokinin A and 5-Hydroxyindoleacetic acid (5HIAA). Echocardiography was used to determine the presence and severity of carcinoid heart disease. Non-parametric receiver operating characteristic curves were constructed for biomarkers, and the area under the curve determined. The severity of cardiac involvement was correlated with the concentration of each biomarker.ResultsA total of 187 patients were identified of whom 37 (20%) had carcinoid heart disease. Significantly higher median values of all biomarkers were found in the patients with cardiac involvement. NT-proBNP and plasma 5HIAA had the highest areas under the curve for the prediction of carcinoid heart disease [NT-proBNP 0.82 (95% confidence interval 0.74-0.90, pConclusionNT-proBNP and plasma 5HIAA are both sensitive and specific biomarkers for the presence of carcinoid heart disease whereas only NT-proBNP is moderately correlated with disease severity.

Carcinoid heart disease is a rare cause of right-sided valvular dysfunction, primarily mediated by serotonin. It is an important complication in patients with carcinoid syndrome and occurs in 20–50% of such patients. Echocardiography is the main technique used for the assessment of carcinoid heart disease, but other imaging modalities are also important, particularly in the quantification of the severity of the disease. We sought to review the role of cardiac imaging in the assessment of carcinoid heart disease.
