Background: Nutritional labels aim to support people to make informed healthy food choices, but many people do not understand the meaning of calories on food labels. Another approach is to provide calorie information with an interpretation of what the calorie content of food means for energy expenditure, known as physical activity calorie equivalent (PACE) labelling. PACE aims to illustrate how many minutes of physical activity are equivalent to the calories contained in food/drinks.

Aims: In people with heart failure (HF), a high body mass index (BMI) has been linked with better outcomes ('obesity paradox'), but there is limited evidence in community populations across long-term follow-up. We aimed to examine the association between BMI and long-term survival in patients with HF in a large primary care cohort.

Methods: We included patients with incident HF aged ≥45 years from the Clinical Practice Research Datalink (2000-2017).

Aims: Heart failure (HF) is a global health burden and new strategies to achieve timely diagnosis and early intervention are urgently needed. Natriuretic peptide (NP) testing can be used to screen for left ventricular systolic dysfunction (LVSD), but evidence on test performance is mixed, and international HF guidelines differ in their recommendations. Our aim was to summarize the evidence on diagnostic accuracy of NP screening for LVSD in general and high-risk community populations and estimate optimal screening thresholds.

Background: Natriuretic peptide (NP) testing is recommended for patients presenting to primary care with symptoms of chronic heart failure (HF) to prioritise referral for diagnosis.

Aim: To report NP test performance at European Society of Cardiology (ESC) and National Institute for Health and Care Excellence (NICE) guideline referral thresholds.

Design And Setting: Diagnostic accuracy study using linked primary and secondary care data (2004 to 2018).

Aims: Heart failure (HF) impairs all aspects of health-related quality of life (HRQoL), but little is known about the effect of developing HF on HRQoL over time. We aimed to report changes in HRQoL over a 13-year period.

Methods And Results: HRQoL was measured in the Echocardiographic Heart of England Screening (ECHOES) study and the ECHOES-X follow-up study (N = 1618) using the SF-36 questionnaire (Version 1).

Aims: Heart failure (HF) is a malignant condition with poor outcomes and is often diagnosed on emergency hospital admission. Natriuretic peptide (NP) testing in primary care is recommended in international guidelines to facilitate timely diagnosis. We aimed to report contemporary trends in NP testing and subsequent HF diagnosis rates over time.

Objective: Heart failure (HF) is a malignant condition requiring urgent treatment. Guidelines recommend natriuretic peptide (NP) testing in primary care to prioritise referral for specialist diagnostic assessment. We aimed to assess association of baseline NP with hospitalisation and mortality in people with newly diagnosed HF.

Objective: Valvular heart disease (VHD) is present in half the population aged >65 years but is usually mild and of uncertain importance. We investigated the association between VHD and its phenotypes with all-cause and cause-specific mortality.

Methods: The OxVALVE (Oxford Valvular Heart Disease) population cohort study screened 4009 participants aged >65 years to establish the presence and severity of VHD.

Aims: Natriuretic peptides are helpful in detecting chronic heart failure (HF) in primary care; however, there are a lack of data evaluating thresholds recommended by clinical guidelines. This study assesses the diagnostic accuracy of N-terminal pro-B-type natriuretic peptide (NT-proBNP) using combined individual patient data from two studies in the UK and the Netherlands.

Methods And Results: Random effects methods were used to estimate the performance characteristics of NT-proBNP thresholds recommended by the European Society of Cardiology (ESC) and the UK National Institute for Health and Care Excellence (NICE) guidelines.

Aims: To understand gender differences in the prognosis of women and men with heart failure, we compared mortality, cause of death and survival trends over time.

Methods And Results: We analysed UK primary care data for 26 725 women and 29 234 men over age 45 years with a new diagnosis of heart failure between 1 January 2000 and 31 December 2017 using the Clinical Practice Research Datalink, inpatient Hospital Episode Statistics and the Office for National Statistics death registry. Age-specific overall survival and cause-specific mortality rates were calculated by gender and year.

Background: The precise age distribution and calculated stroke risk of screen-detected atrial fibrillation (AF) is not known. Therefore, it is not possible to determine the number needed to screen (NNS) to identify one treatable new AF case (NNS-Rx) (i.e.

Aim: To provide reliable survival estimates for people with chronic heart failure and explain variation in survival by key factors including age at diagnosis, left ventricular ejection fraction, decade of diagnosis, and study setting.

Methods And Results: We searched in relevant databases from inception to August 2018 for non-interventional studies reporting survival rates for patients with chronic or stable heart failure in any ambulatory setting. Across the 60 included studies, there was survival data for 1.

Objectives: To report reliable estimates of short term and long term survival rates for people with a diagnosis of heart failure and to assess trends over time by year of diagnosis, hospital admission, and socioeconomic group.

Background: Heart failure (HF) is a common condition affecting more than 10% of those over 70 years of age. Reliable estimates of survival following a diagnosis of HF are important to guide management and facilitate advanced care planning. Most existing research has focused on survival rates for patients admitted to hospital with acute HF.

Background: Detection and treatment of heart failure (HF) can improve quality of life and reduce premature mortality. However, symptoms such as breathlessness are common in primary care, have a variety of causes and not all patients require cardiac imaging. In systems where healthcare resources are limited, ensuring those patients who are likely to have HF undergo appropriate and timely investigation is vital.

Background: Symptoms of breathlessness, fatigue, and ankle swelling are common in general practice but deciding which patients are likely to have heart failure is challenging.

Aim: To evaluate the performance of a clinical decision rule (CDR), with or without N-Terminal pro-B type natriuretic peptide (NT-proBNP) assay, for identifying heart failure.

Design And Setting: Prospective, observational, diagnostic validation study of patients aged >55 years, presenting with shortness of breath, lethargy, or ankle oedema, from 28 general practices in England.

Background: Care home residents with stroke-related disabilities have significant activity limitations. Phase II trial results suggested a potential benefit of occupational therapy (OT) in maintaining residents' capacity to engage in functional activity.

Objective: To evaluate the clinical effectiveness and cost-effectiveness of a targeted course of OT in maintaining functional activity and reducing further health risks from inactivity for UK care home residents living with stroke-related disabilities.

Background: Heart failure is a major cause of mortality and morbidity. As mortality rates are high, it is important that patients seen by general practitioners with symptoms suggestive of heart failure are identified quickly and treated appropriately. Identifying patients with heart failure or deciding which patients need further tests is a challenge.

There is increased demand for emergency healthcare by the public when abroad. This study aimed to investigate adults' reported level of knowledge about how to contact emergency healthcare services while abroad. A street survey was administered at various times, over several days, to 554 members of the general public who had been abroad in the previous 18 months.
