Aims and objectives To understand the views of patients and professionals on the acceptability and perceived usefulness of telemonitoring in the management of chronic heart failure in the context of day-to-day care provision. Background There is an increasing interest in the potential for telemonitoring to support the home-based management of patients with chronic heart failure. However, little is known about the views of patients and professionals on the use of telemonitoring in this context. A chronic heart failure telemonitoring service was set-up by NHS Lothian, Scotland, to evaluate the intervention. Design A qualitative design was adopted to explore the views of patients and professionals participating in the service. Methods Semi-structured interviews were undertaken with 18 patients (61% male, mean age 75 years) and five professionals participating at different time points in this new service. Interviews were audio recorded, coded and thematically analysed using the Framework approach. Results Five main themes were identified: 'information, support and reassurance'; 'compliance and dependence'; 'changes and challenges'; 'determining the criteria for patient applicability to telemonitoring'; and 'continuity of care'. Conclusion Patients and professionals considered telemonitoring useful in the management of chronic heart failure, although with some caveats. Telemonitoring was popular with patients because they felt reassurance arising from what was perceived as continuous practitioner surveillance. Professionals expressed concern regarding perceived patient dependence on practitioner support. Increased workload was also a concern. Both groups acknowledged the need for improved technology and changes to service provision in order to better meet the intended objectives of the service. Relevance to clinical practice Although popular with patients, professionals emphasised the importance of case selection and adequate training and support, both for patients and themselves, in order to maximise the expected benefits of the service, particularly with regard to enabling self-management.

The article discusses a study which investigated the link between lowering the diagnostic threshold for myocardial infarction (MI) with a sensitive troponin assay and improved clinical outcomes. The study involved patients with acute coronary syndrome (ACS) admitted to the Royal Infirmary of Edinburgh in Scotland. Less than 0.05 ng/mL plasma troponin concentrations were found in 1,340 patients. An increase in the diagnosis of MI due to the implementation of a sensitive troponin assay was observed in patients with suspected ACS.

The article offers information on a study regarding the implications of lowering the diagnostic threshold of plasma troponin concentration to the 99th centile. According to the results, it increased the diagnosis of myocardial infarction by 47 percent and identified patients who were 4 to5 times more likely to die or have a recurrent myocardial infarct than those below this threshold.

Objective: Emergency Department (ED) attendances with chest pain reduced during the COVID-19 lockdown. We performed a service evaluation project in NHS Lothian to explore how and why the COVID-19 pandemic and public health advice had affected chest pain presentations and help-seeking behaviour at an individual patient level using a qualitative interview approach., Methods: We carried out 28 semi-structured telephone interviews with a convenience sample of patients who presented with chest pain during lockdown and in patients with known coronary heart disease under the outpatient care of a cardiologist in April and May 2020. Interviews were audio recorded and voice files listened to while making detailed notes. Salient themes and issues were documented as verbatim extracts. Interviews were analysed thematically., Results: Patient interviews revealed three main themes. 1) pandemic help-seeking behaviour; describing how participants made the decision to seek professional healthcare assessment. 2) COVID-19 exposure concerns; describing how the subthemes of perceived vulnerability, wishing to protect others and adding pressure to the health service shaped their decision making for an episode of acute chest pain. 3) hospital experience; describing the difference between the imagined and actual experience in hospital., Conclusions: Qualitative interviews revealed how the pandemic shaped help-seeking practices, how patients interpreted their personal vulnerability to the virus, and described patient experience of attending hospital for assessment during this time. As patient numbers presenting to hospital appeared to mirror public health messaging, dynamic monitoring of this messaging should evaluate public response to healthcare campaigns to ensure the net impact on health, pandemic and non-pandemic related, is optimised., Competing Interests: The authors have declared that no competing interests exist.

Objective: To assess the relation between troponin concentration, assay precision, and clinical outcomes in patients with suspected acute coronary syndrome., Design: Cohort study., Setting: Tertiary centre in Scotland., Participants: 2092 consecutive patients admitted with suspected acute coronary syndrome were stratified with a sensitive troponin I assay into three groups (<0.012, 0.012-0.049, and ≥0.050 µg/L) based on the 99th centile for troponin concentration (0.012 µg/L; coefficient of variation 20.8%) and the diagnostic threshold (0.050 µg/L; 7.2%)., Main Outcome Measure: One year survival without events (recurrent myocardial infarction, death) in patients grouped by troponin concentration., Results: Troponin I concentrations were <0.012 µg/L in 988 patients (47%), 0.012-0.049 µg/L in 352 patients (17%), and ≥0.050 µg/L in 752 patients (36%). Adoption of the 99th centile would increase the number of people receiving a diagnosis of myocardial infarction from 752 to 1104: a relative increase of 47%. At one year, patients with troponin concentrations of 0.012-0.049 µg/L were more likely to be dead or readmitted with recurrent myocardial infarction than those with troponin concentrations <0.012 µg/L (13% v 3%, P<0.001; odds ratio 4.7, 95% confidence interval 2.9 to 7.9). Compared with troponin ≥0.050 µg/L, patients with troponin 0.012-0.049 µg/L had a higher risk profile but were less likely to have a diagnosis of, or be investigated and treated for, acute coronary syndrome., Conclusion: Lowering the diagnostic threshold to the 99th centile and accepting greater assay imprecision would identify more patients with acute coronary syndrome at risk of recurrent myocardial infarction and death but would increase the diagnosis of myocardial infarction by 47%. It remains to be established whether reclassification of these patients and treatment for myocardial infarction would improve outcome.

Aims: Obstructive sleep apnoea (OSA) is highly prevalent in patients with chronic heart failure (CHF) and may contribute to CHF progression. We aimed to determine whether treatment of OSA with continuous positive airway pressure (CPAP) would improve subjective and objective measures of heart failure severity in patients with CHF and OSA., Methods and Results: Twenty-six patients with stable symptomatic CHF and OSA were randomized to nocturnal auto-titrating CPAP or sham CPAP for 6 weeks each in crossover design. Study co-primary endpoints were changes in peak VO(2) and 6 min walk distance. Secondary endpoints were changes in left ventricular ejection fraction, VE/VCO(2) slope, plasma neurohormonal markers, and quality-of-life measures. Twenty-three patients completed the study protocol. Mean CPAP and sham CPAP usage were 3.5 +/- 2.5 and 3.3 +/- 2.2 h/night, respectively (P = 0.31). CPAP treatment was associated with improvements in daytime sleepiness (Epworth Sleepiness Score 7 +/- 4 vs. 8 +/- 5, P = 0.04) but not in other quality-of-life measures. There were no changes in other study endpoints., Conclusion: In patients with CHF and OSA, auto-titrating CPAP improves daytime sleepiness but not other subjective or objective measures of CHF severity. These data suggest that the potential therapeutic benefits of CPAP in CHF are achieved by alleviation of OSA rather than by improvement in cardiac function.
