Who approves/pays for additional monitoring?

Major considerations in the provision of healthcare are availability, affordability, accessibility, and appropriateness, especially in the setting of heart failure where disease burden is growing, developments have been rapid and newer biomarkers, diagnostic and imaging techniques, monitoring systems, devices, procedures, and drugs have all been developed in a relatively short period of time. Many monitoring and diagnostic systems have been developed but the disproportionate cost of conducting trials of their effectiveness has limited their uptake. There are added complexities, in that the utilization of doctors for the supervision of the monitoring results may be optimal in one setting and not in another because of differences in the characteristics of organization of healthcare provision, making even interpretation of the trials we have had, still difficult to interpret. New technologies are continuously changing the approach to healthcare and will reshape the structure of the healthcare systems in the future. Mobile technologies can empower patients and carers by giving them more control over their health and social care needs and reducing their dependence on healthcare professionals for monitoring their health, but a significant problem is the integration of the multitude of monitored parameters with clinical data and the recognition of intervention thresholds. Digital technology can help, but we need to prove its cost/efficacy and how it will be paid for. Governments in many European countries and worldwide are trying to establish frameworks that promote the convergence of standards and regulations for telemedicine solutions and yet simultaneously health authorities are closely scrutinizing healthcare spending, with the objective of reducing and optimizing expenditure in the provision of health services. There are multiple factors to be considered for the reimbursement models associated with the implementation of physiological monitoring yet it remains a challenge in cash-strapped health systems

Androgens and Adipose Tissue in Males: A Complex and Reciprocal Interplay

Clinical evidence shows that in males obesity is frequently associated with hypogonadism and vice versa; also, low testosterone levels have been considered a “hallmark” of metabolic syndrome in men. These observations indicate that there is a strict connection between anatomically and functionally distinct cell types such as white adipocytes and Leydig cells, that synthesize testosterone. Adipose tissue is able to control several functions of the testis through its products secreted in the bloodstream. On the other hand, circulating levels of testosterone and estradiol deeply affect adipocyte proliferation, differentiation, and fat mass distribution, hereby controlling critical metabolic functions, such as food intake, insulin sensitivity, vascular reactivity, and immunity. This paper highlights the existing clinical and experimental evidence linking androgens and adipose tissue and illustrates the consequences occurring when the balance between fat mass distribution and eugonadism is lost

Association between use of novel glucose-lowering drugs and COVID-19 hospitalization and death in patients with type 2 diabetes: a nationwide registry analysis

Aims Type 2 diabetes (T2DM) in patients with coronavirus disease-19 (COVID-19) is associated with a worse prognosis. We separately investigated the associations between the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and dipeptidyl peptidase-4 inhibitors (DPP-4i), and the risk of COVID-19 hospitalization and death. Methods and results Patients with T2DM registered in the Swedish National Patient Registry and alive on 1 February 2020 were included. 'Incident severe COVID-19' was defined as the first hospitalization and/or death from COVID-19. A modified Poisson regression approach was applied to a 1:1 propensity score-matched population receiving vs. not receiving SGLT2i, GLP-1 RA, and DPP-4i to analyse the associations between their use and (I) incident severe COVID-19 and (II) risk of 30-day mortality in patients hospitalized for COVID-19. Among 344 413 patients, 39 172 (11%) were treated with SGLT2i, 34 290 (10%) with GLP-1 RA, and 53 044 (15%) with DPP-4i; 9538 (2.8%) had incident severe COVID-19 by 15 May 2021. SGLT2i and DPP-4i were associated with a 10% and 11% higher risk of incident severe COVID-19, respectively, whereas there was no association for GLP-1 RA. DPP-4i was also associated with a 10% higher 30-day mortality in patients hospitalized for COVID-19, whereas there was no association for SGLT2i and GLP-1 RA. Conclusion SGLT2i and DPP-4i use were associated with a higher risk of incident severe COVID-19. DPP-4i use was associated with higher 30-day mortality in patients with COVID-19, whereas SGLT2i use was not. No increased risk for any outcome was observed with GLP-1 RA

Side effects and treatment initiation barriers of sodium-glucose cotransporter 2 inhibitors in heart failure: a systematic review and meta-analysis

Aims Physicians are sometimes reluctant to initiate guideline-directed therapy in patients with heart failure and reduced ejection fraction (HFrEF) due to concerns of adverse events. We explored the risk of hypotension, volume depletion, and acute kidney injury (AKI) on sodium–glucose cotransporter 2 (SGLT2) inhibitors in HFrEF populations. Methods and results We determined summary risk ratios (RRs) by conducting a meta-analysis on reported aforementioned adverse events on SGLT2 inhibitors from randomized controlled trials. We explored robustness of meta-analyses by computing fragility and/or reverse fragility index (FI or RFI) and its corresponding fragility quotient (FQ or RFQ) for each outcome. A total of 10 050 patients with HFrEF entered the final meta-analysis. Hypotension was reported in 4.5% (219/4836) on SGLT2 inhibitors and in 4.1% (202/4846) on placebo (RR 1.09, 95% confidence interval [CI] 0.91–1.31, p = 0.36). An RFI of 21 and RFQ of 0.002 suggest robust findings for hypotension. Volume depletion occurred in 9.4% (473/5019) on SGLT2 inhibitors and in 8.7% (438/5031) on placebo (RR 1.07, 95% CI 0.95–1.21, p = 0.25), respectively. RFI of 19 and RFQ of 0.001 suggest moderately robust findings for volume depletion. AKI was reported in fewer patients (1.9% [95/4888]) on SGLT2 inhibitors than on placebo (2.8% [140/4899]) providing lower incidence of AKI (RR 0.69, 95% CI 0.51–0.93, p = 0.02). FI of 14 and RFQ of 0.001 suggest moderately robust findings for AKI. Conclusion Sodium–glucose cotransporter 2 inhibitor therapy is not associated with a clinically relevant risk of hypotension and volume depletion. Its use reduces the risk of AKI. This analysis supports current guideline recommendations on early use of SGLT2 inhibitors

Efficacy of ivabradine in heart failure patients with a high-risk profile (analysis from the SHIFT trial)

Aims Early start and patient profile-oriented heart failure (HF) management has been recommended. In this post hoc analysis from the SHIFT trial, we analysed the treatment effects of ivabradine in HF patients with systolic blood pressure (SBP) < 110 mmHg, resting heart rate (RHR) ≥ 75 b.p.m., left ventricular ejection fraction (LVEF) ≤ 25%, New York Heart Association (NYHA) Class III/IV, and their combination. Methods and results The SHIFT trial enrolled 6505 patients (LVEF ≤ 35% and RHR ≥ 70 b.p.m.), randomized to ivabradine or placebo on the background of guideline-defined standard care. Compared with placebo, ivabradine was associated with a similar relative risk reduction of the primary endpoint (cardiovascular death or HF hospitalization) in patients with SBP < 110 and ≥110 mmHg [hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.74–1.08 vs. HR 0.80, 95% CI 0.72–0.89, P interaction = 0.34], LVEF ≤ 25% and >25% (HR 0.85, 95% CI 0.72–1.01 vs. HR 0.80, 95% CI 0.71–0.90, P interaction = 0.53), and NYHA III–IV and II (HR 0.83, 95% CI 0.74–0.94 vs. HR 0.81, 95% CI 0.69–0.94, P interaction = 0.79). The effect was more pronounced in patients with RHR ≥ 75 compared with <75 (HR 0.76, 95% CI 0.68–0.85 vs. HR 0.97, 95% CI 0.81–0.1.16, P interaction = 0.02). When combining these profiling parameters, treatment with ivabradine was also associated with risk reductions comparable with patients with low-risk profiles for the primary endpoint (relative risk reduction 29%), cardiovascular death (11%), HF death (49%), and HF hospitalization (38%; all P values for interaction: 0.40). No safety concerns were observed between study groups. Conclusions Our analysis shows that RHR reduction with ivabradine is effective and improves clinical outcomes in HF patients across various risk indicators such as low SBP, high RHR, low LVEF, and high NYHA class to a similar extent and without safety concern

Monitoring of biomarkers in heart failure.

The role of biomarkers is increasingly recognized in heart failure (HF) management, for diagnosis, prognostication, and screening of high-risk patients. Beyond natriuretic peptides and troponins, the utility of novel, emerging biomarkers is less established. This document reflects the key points of a Heart Failure Association of the European Society of Cardiology (ESC) consensus meeting on biomarker monitoring in HF

Myocarditis following COVID-19 vaccine: incidence, presentation, diagnosis, pathophysiology, therapy, and outcomes put into perspective. A clinical consensus document supported by the Heart Failure Association of the European Society of Cardiology (ESC) and the ESC Working Group on Myocardial and Pericardial Diseases.

Over 10 million doses of COVID-19 vaccines based on RNA technology, viral vectors, recombinant protein, and inactivated virus have been administered worldwide. Although generally very safe, post-vaccine myocarditis can result from adaptive humoral and cellular, cardiac-specific inflammation within days and weeks of vaccination. Rates of vaccine-associated myocarditis vary by age and sex with the highest rates in males between 12 and 39 years. The clinical course is generally mild with rare cases of left ventricular dysfunction, heart failure and arrhythmias. Mild cases are likely underdiagnosed as cardiac magnetic resonance imaging (CMR) is not commonly performed even in suspected cases and not at all in asymptomatic and mildly symptomatic patients. Hospitalization of symptomatic patients with electrocardiographic changes and increased plasma troponin levels is considered necessary in the acute phase to monitor for arrhythmias and potential decline in left ventricular function. In addition to evaluation for symptoms, electrocardiographic changes and elevated troponin levels, CMR is the best non-invasive diagnostic tool with endomyocardial biopsy being restricted to severe cases with heart failure and/or arrhythmias. The management beyond guideline-directed treatment of heart failure and arrhythmias includes non-specific measures to control pain. Anti-inflammatory drugs such as non-steroidal anti-inflammatory drugs, and corticosteroids have been used in more severe cases, with only anecdotal evidence for their effectiveness. In all age groups studied, the overall risks of SARS-CoV-2 infection-related hospitalization and death are hugely greater than the risks from post-vaccine myocarditis. This consensus statement serves as a practical resource for physicians in their clinical practice, to understand, diagnose, and manage affected patients. Furthermore, it is intended to stimulate research in this area.The authors met via teleconference on several occasions and the main authors once in person. Each author performed an in-depth review of the literature on their topic. Finally, each expert presented their interpretation of the literature on their topic to the expert panel and a consensus was made together regarding recommendations.
