Outcomes in Cardiac Transthyretin Amyloidosis and Association With New York Heart Association Class: Real-World Data.

BACKGROUND: Results from ATTR-ACT (Safety and Efficacy of Tafamidis in Patients With Transthyretin Cardiomyopathy) indicate that tafamidis prolongs survival and reduces cardiovascular hospitalizations in cardiac transthyretin amyloidosis (ATTR-CA). However, real-world data supporting these findings are scarce. Thus, we sought to characterize the clinical outcome of patients with ATTR-CA treated with tafamidis in a real-world setting and assess the prognostic role of the New York Heart Association (NYHA) classification. METHODS AND RESULTS: We conducted a retrospective observational study, enrolling a consecutive sample of patients with ATTR-CA (wild-type or variant) treated with tafamidis. Clinical outcome was tracked through follow-up visits or phone calls. Primary outcomes were death and major adverse cardiac events (MACE), a composite end point of death and hospitalizations for acute cardiac decompensation, myocardial infarction, severe arrythmias, or stroke. Kaplan-Meier analysis estimated overall and MACE-free survival including NYHA subgroups (NYHA I/II versus NYHA III). One hundred sixty-seven patients with ATTR-CA (94.6% wild-type) were enrolled and followed for a median of 539 [323-869] days. Median overall survival was not reached. Estimated 1-year, 2-year, and 5-year overall survival among the whole cohort was 93.5%, 85.9%, and 70.2%, respectively. Overall survival was higher in the NYHA I/II subgroup (P=0.002). Median MACE-free survival time was 1082 (95% CI, 962-1202) days. MACE-free survival was higher in the NYHA I/II subgroup (P<0.001). With respective hazard ratios of 5.85 (95% CI, 1.48-23.18; P=0.012) and 3.95 (95% CI, 1.99-7.84; P<0.001), NYHA III was an independent predictor of death and MACE. CONCLUSIONS: Treatment of ATTR-CA with tafamidis led to substantial improvements of clinical outcome. NYHA classification at treatment initiation is a reliable tool to provide patients with individualized prognostic information.

Diagnostic value of left ventricular layer strain and specific regional strain patterns in cardiac amyloidosis and Fabry disease.

Aims: Layer-specific left ventricular (LV) strain alterations have been suggested as a specific finding in Fabry disease (FD). Our study aimed to assess the diagnostic value of layer-specific radial strain (RS) indices compared to the established LV regional strain pattern in cardiac amyloidosis (CA) and FD, i.e. apical sparing and posterolateral strain deficiency (PLSD). Methods and results: We retrospectively analysed the global, subendocardial, subepicardial LV radial strain, the corresponding strain gradient, as well as the regional and global longitudinal strain. The diagnostic accuracy of the diverse LV strain analyses was comparatively assessed using receiver operating characteristic curve and multivariable regression analyses. In 40 FD and 76 CA patients, CA featured more reduced layer strain values [global RS -12.3 (-15.6 to -9.6) in CA vs. -16.7 (-20.0 to -13.6) in FD; P < 0.001; subendocardial RS -22.3 (-27.4 to -15.9) vs. -28.3 (-31.8 to -23.6), P < 0.001; subepicardial RS -6.6 (-8.6 to -4.7) in CA vs. -8.9 (-11.7 to - 6.5) in FD; P < 0.001]. Global radial and longitudinal strain held an area under the curve (AUC) of 0.75 (0.66-0.84) and AUC 0.73 (0.63-0.83). While the apical sparing and PLSD strain pattern showed the highest accuracy as single parameters [AUC 0.87 (0.79-0.95) and 0.81 (0.72-0.89), P < 0.001], the combination of subendocardial RS and the apical sparing pattern featured the highest diagnostic accuracy [AUC 0.92 (0.87-0.97)]. Conclusion: Combining radial strain-derived parameters to the established strain pattern apical sparing and PLSD improve the diagnostic accuracy in the echocardiographic assessment in suspected storage disease.

Impact of telemedical management on hospitalization and mortality in heart failure patients with diabetes: a post-hoc subgroup analysis of the TIM-HF2 trial.

BACKGROUND: The TIM-HF2 study demonstrated that remote patient management (RPM) in a well-defined heart failure (HF) population reduced the percentage of days lost due to unplanned cardiovascular hospital admissions or all-cause death during 1-year follow-up (hazard ratio 0.80) and all-cause mortality alone (HR 0.70). Higher rates of hospital admissions and mortality have been reported in HF patients with diabetes compared with HF patients without diabetes. Therefore, in a post-hoc analysis of the TIM-HF2 study, we investigated the efficacy of RPM in HF patients with diabetes. METHODS: TIM-HF2 study was a randomized, controlled, unmasked (concealed randomization), multicentre trial, performed in Germany between August 2013 and May 2018. HF-Patients in NYHA class II/III who had a HF-related hospital admission within the previous 12 months, irrespective of left ventricular ejection fraction, and were randomized to usual care with or without added RPM and followed for 1 year. The primary endpoint was days lost due to unplanned cardiovascular hospitalization or due to death of any cause. This post-hoc analysis included 707 HF patients with diabetes. RESULTS: In HF patients with diabetes, RPM reduced the percentage of days lost due to cardiovascular hospitalization or death compared with usual care (HR 0.66, 95% CI 0.48-0.90), and the rate of all-cause mortality alone (HR 0.52, 95% CI 0.32-0.85). RPM was also associated with an improvement in quality of life (mean difference in change in global score of Minnesota Living with Heart Failure Questionnaire score (MLHFQ): - 3.4, 95% CI - 6.2 to - 0.6). CONCLUSION: These results support the use of RPM in HF patients with diabetes. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT01878630.

Neurological affection and serum neurofilament light chain in wild type transthyretin amyloidosis.

In contrast to inherited transthyretin amyloidosis (A-ATTRv), neuropathy is not a classic leading symptom of wild type transthyretin amyloidosis (A-ATTRwt). However, neurological symptoms are increasingly relevant in A-ATTRwt as well. To better understand the role of neurological symptoms in A-ATTRwt, A-ATTRwt patients were prospectively characterized at Amyloidosis Center Charité Berlin (ACCB) between 2018 and 2023 using detailed neurological examination, quality of life questionnaires, and analysis of age- and BMI-adapted serum neurofilament light chain (NFL) levels. 16 out of 73 (21.9%) patients presented with a severe neuropathy which we defined by a Neuropathy Impairment Score (NIS) of 20 or more. In this group, quality of life was reduced, peripheral neuropathy was more severe, and spinal stenosis and joint replacements were frequent. Age- and BMI matched serum NFL levels were markedly elevated in patients with a NIS ≥ 20. We therefore conclude that highly abnormal values in neuropathy scores such as the NIS occur in A-ATTRwt, and have an important impact on quality of life. Both peripheral neuropathy and spinal canal stenosis are likely contributors. Serum NFL may serve as a biomarker for neurological affection in patients with A-ATTRwt. It will be important to consider neurological aspects of A-ATTRwt for diagnosis, clinical follow-up, and future treatment development.

Right heart and left atrial strain to differentiate cardiac amyloidosis and Fabry disease.

Echocardiographic differentiation of cardiac amyloidosis (CA) and Fabry disease (FD) is often challenging using standard echocardiographic parameters. We retrospectively analyzed the diagnostic accuracy of right heart and left atrial strain parameters to discriminate CA from FD using receiver operating characteristic curve analyses and logistic regression models. A total of 47 FD and 88 CA patients with left ventricular wall thickening were analyzed. The comparison of both cardiomyopathies revealed significantly reduced global and free wall longitudinal right ventricular strain (RVS; global RVS: CA - 13 ± 4%, n = 67, vs. FD - 18 ± 4%, n = 39, p < 0.001) as well as right atrial strain (RAS; reservoir RAS: CA 12 ± 8%, n = 70, vs. FD 26 ± 9%, n = 40, p < 0.001) and left atrial strain (LAS) in CA patients. Individually, global RVS as well as phasic LAS and RAS showed the highest diagnostic accuracy to distinguish CA and FD. The best diagnostic accuracy was achieved by combining the age, basal RV diameter, global RVS, and reservoir and conduit RAS (area under the curve 0.96 [95% CI 0.90-1.00]). Differential echocardiographic diagnostic work-up of patients with suspected CA or FD can be improved by integrating structural and functional parameters of the right heart and the left atrium.Trial registration: DRKS00027403.

Impact of ACE I gene insertion/deletion, A-240T polymorphisms and the renin-angiotensin-aldosterone system on COVID-19 disease.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is driven by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which has led to an enormous burden on patient morbidity and mortality. The renin-angiotensin-aldosterone system (RAAS) plays a significant role in various pulmonary diseases. Since SARS-CoV-2 utilizes the angiotensin-converting enzyme (ACE)2 receptor to exert its virulence and pathogenicity, the RAAS is of particular importance in COVID 19. METHODS: Our preliminary study investigates retrospectively the influence of selected ACE-polymorphisms (I/D location at intron 16 in the B-coding sequence (rs4646994) and A-240T (rs 4291) at the A-promoter) as well as ACE1 and ACE2 serum levels on disease severity and the inflammatory response in inpatients and outpatients with COVID-19. RESULTS: Our study included 96 outpatients and 88 inpatients (65.9% male, mean age 60 years) with COVID-19 from April to December 2020 in four locations in Germany. Of the hospitalized patients, 88.6% participants were moderately ill (n = 78, 64% male, median age 60 years), and 11.4% participants were severely ill or deceased (n = 10, 90% male, median age 71 years). We found no polymorphism-related difference in disease, in age distribution, time to hospitalization and time of hospitalization for the inpatient group. ACE1 serum levels were significantly increased in the DD compared to the II polymorphism and in the TT compared to the AA polymorphism. There was no significant difference in ACE 1 serum levels l between moderately ill and severely ill patients. However, participants requiring oxygen supplementation had significantly elevated ACE1 levels compared to participants not requiring oxygen, with no difference in ACE2 levels whereas females had significantly higher ACE2 levels. CONCLUSIONS: Although there were no differences in the distribution of ACE polymorphisms in disease severity, we found increased proinflammatory regulation of the RAAS in patients with oxygen demand and increased serum ACE2 levels in women, indicating a possible enhanced anti-inflammatory immune response.

Diagnostic value of papillary muscle hypertrophy and mitral valve thickness to discriminate cardiac amyloidosis and Fabry disease.

BACKGROUND: Cardiac amyloidosis (CA) and Fabry disease (FD) cause myocardial damage but may also affect the valvular and subvalvular apparatus. We aimed to evaluate the diagnostic accuracy of new echocardiographic indices including mitral valve thickness and papillary muscle (PM) hypertrophy to differentiate CA and FD. METHODS: In patients with confirmed CA and FD, a detailed assessment of valvular function, mitral valve leaflet thickness and PM area as well as PM left ventricular area ratio (PM/LV-ratio) was performed in offline analyses. Receiver operating characteristic curve analyses were conducted to determine the diagnostic accuracy of mitral valve thickness, PM hypertrophy, and PM/LV-ratio to distinguish CA from FD. RESULTS: We retrospectively analyzed a cohort of 129 patients (FD n = 49, CA n = 80). CA patients showed significantly more thickened mitral valve leaflets (4.1 ± 1.3 mm vs. 2.9 ± 1.1 mm, p < 0.001) and a higher PM area [4.0 (3.1-4.6) mm2 vs. 2.8 (2.1-4.6) mm2, p = 0.009] with a comparable PM/LV-ratio in both groups. Mitral valve thickness showed the highest diagnostic accuracy to discriminate CA [AUC 0.77 (95% CI 0.67-0.87)]. The prevalence of aortic, tricuspid, and pulmonary valve regurgitation was significantly higher in CA (aortic regurgitation ≥ II° 13% vs. 4%, tricuspid regurgitation≥ II° 19% vs. 8%, p < 0.001). CONCLUSION: Our results suggest that the assessment of mitral valve thickness may be a new useful echocardiographic parameter to differentiate CA and FD, whereas papillary muscle hypertrophy and PM/LV-ratio showed a limited diagnostic performance to discriminate CA.

mRNA vaccines for COVID-19 are safe and clinically effective in patients with cardiac amyloidosis.

INTRODUCTION: Amyloidosis is a rare disease in which malformed proteins are deposited in tissues occurring mostly commonly in older age. These deposits can lead to severe organ dysfunction e.g. in the myocardium with great impact on prognosis. The Covid-19 pandemic has caused excess mortality worldwide since 2020. Risk factors for a severe course include pre-existing cardiac diseases like heart failure and advanced age. Therefore, vaccination against Sars-CoV2 viruses is highly recommended for patients with cardiac amyloidosis. However, since there are no specific data on mRNA vaccines in patients with cardiac amyloidosis, some patients have concerns about cardiac adverse events following immunization (AEFI), such as myocarditis. PURPOSE: The purpose of the study is to assess the safety and efficacy of mRNA vaccines in patients with cardiac amyloidosis. METHODS: Patients of the Amyloidosis Center Charité Berlin (ACCB) were assessed about the vaccination, its tolerability and clinical effectiveness. To date, we included 62 patients (54 men) with a median age of 82,5 years (range 37 to 92). 46 patients had wtATTR amyloidosis, ten patients had hATTR amyloidosis, and six patients had AL amyloidosis. The mean systolic left ventricular function was 51% (range 30 to 62) with a mean global strain of -11,5% (range -18,5 to -3,1). The mean NT-pro-BNP was 1145 ng/l (range 24 to 48297). RESULTS: 59 patients were triple vaccinated and three patients so far are double vaccinated. Three of the patients were unvaccinated. 171 of the vaccine doses administered were mRNA vaccines and eight doses were a viral vector-vaccine. None of the patients reported severe side effects. Thirteen patients reported feeling of pressure and pain at the injection site after vaccination and four patients had fever of maximum two days, eight patients reported lower general condition of maximum five days. One patient reported malaise for 14 days after each vaccination, which resolved spontaneously. There was no clinical or laboratory evidence of suspected vaccine-induced myocarditis. Five patients reported of a COVID-19 breakthrough infection, all of which with a mild course of disease. None of the patients had symptoms of worsening heart failure in temporal relation to the vaccination. Most of the vaccinations (103) were performed at an official vaccination center, 59 were performed at a general practitioner. CONCLUSION: In patients with cardiac amyloidosis, mRNA vaccines for COVID-19 are safe with respect to severe cardiac adverse events and show effective protection against clinically relevant SARS-CoV2 infection.

Serum interleukin-6, procalcitonin, and C-reactive protein at hospital admission can identify patients at low risk for severe COVID-19 progression.

Background: COVID-19 can show a variable course, from asymptomatic infections to acute respiratory failure and death. For efficient allocation of resources, patients should be stratified according to their risk for a severe course as early as possible. Methods: 135 hospitalized patients with COVID-19 pneumonia at four German hospitals were prospectively included in this observational study. A standardized clinical laboratory profile was taken at hospital admission and a panel of serum markers with possible roles in the COVID-associated cytokine storm were also determined. 112 patients could be evaluated. The primary endpoint of ventilator requirement or death within 30 days of symptom onset was met by 13 patients. Results: Serum elevations of interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) at hospital admission were each highly significantly (p < 0.001) associated with ventilator requirement/death within 30 days of symptom onset. With a sensitivity of 92% and a specificity of 65-67%, IL-6 ≥ 52.8 pg/ml, PCT ≥ 0.11 ng/ml, and CRP ≥ 71.1 mg/L were predictive of a severe course of COVID-19. Positive likelihood ratios were between 2.6-2.8 and negative likelihood ratios were between 0.11-0.13 for these three markers. Conclusion: Negative likelihood ratios indicate that IL-6, PCT, and CRP at hospital admission can be used for identifying patients at low risk for severe COVID-19 progression.

[Clinical application of large language models : Does ChatGPT replace medical report formulation? An experience report]. / Anwendung von "large language models" in der Klinik : Ersetzt ChatGPT die Arztbrieferstellung? Ein Erfahrungsbericht.

Artificial intelligence (AI)-based language models, such as ChatGPT offer an enormous potential for research and medical care but also for clinical workflow optimization by making medical documentation easier and more efficient in taking over standardized routine tasks. With their ability to guess a text's content using word statistics and thus outputting contextually relevant results in chat dialogues, large language models (LLM) can provide appropriate summaries of medical documentation for different target groups. For instance, text generation in easy to understand language could potentially contribute to an increase in patients' health literacy and, consequently, to increased adherence to treatment. Subsequent, the function of AI-based chatbot models to improve user experiences and enhance competence in the use of AI-based language models will be adressed. Current limitations and chances in creating epicrises are presented as an experience report. In the future, the implementation of local LLMs in medical management systems (hospital information systems, HIS and practice administration systems, PAS) and in conjunction with the electronic patient records (ePA) can fundamentally change clinical and outpatient care.

From Videogames to Teaching - Different Camera Perspectives in an Interactive Synchronous Online Tutorial.

The global COVID-19 pandemic has required clinical skills training to be transferred to an online format. An interactive synchronous online tutorial with different camera perspectives was developed. In a survey, 79% of the students preferred the first-person perspective, which allowed students to view the abdominal examination through the examiner's eyes.

Gaze patterns reflect and predict expertise in dynamic echocardiographic imaging.

Purpose: Echocardiography is the most important modality in cardiac imaging. Rapid valid visual assessment is a critical skill for image interpretation. However, it is unclear how skilled viewers assess echocardiographic images. Therefore, guidance and implicit advice are needed for learners to achieve valid image interpretation. Approach: Using a signal detection approach, we compared 15 certified experts with 15 medical students in their diagnostic decision-making and viewing behavior. To quantify attention allocation, we recorded eye movements while viewing dynamic echocardiographic imaging loops of patients with reduced ejection fraction and healthy controls. Participants evaluated left ventricular ejection fraction and image quality (as diagnostic and visual control tasks, respectively). Results: Experts were much better at discriminating between patients and healthy controls ( d ' of 2.58, versus 0.98 for novices). Eye tracking revealed that experts fixated diagnostically relevant areas earlier and more often, whereas novices were distracted by visually salient task-irrelevant stimuli. We show that expertise status can be almost perfectly classified either based on judgments or purely on eye movements and that an expertise score derived from viewing behavior predicts diagnostic quality. Conclusions: Judgments and eye tracking revealed significant differences between echocardiography experts and novices that can be used to derive numerical expertise scores. Experts have implicitly learned to ignore the salient motion cue presented by the mitral valve and to focus on the diagnostically more relevant left ventricle. These findings have implications for echocardiography training, objective characterization of echocardiographic expertise, and the design of user-friendly interfaces for echocardiography.

Patient reported experience and adherence to remote patient management in chronic heart failure patients: a posthoc analysis of the TIM-HF2 trial.

AIMS: Remote patient management (RPM) enables early detection and prevention of deterioration in heart failure (HF) patients by measuring vital parameters. The analysis objective is to assess patient reported experience with RPM, adherence to daily measurements, and outline affecting factors both. METHODS AND RESULTS: Telemedical interventional management in-HF2 was conducted in 2013-18 with 1 538 HF patients with a 12-month follow-up. Under guidance of HF nurses, patients had to measure daily weight, blood pressure, electrocardiogram, and self-rated health status. At the end of the study, patients received a programme survey to analyse patient perceptions and satisfaction with telemedicine care and study organization. Adherence was distinguished between measurement of at least one [incomplete adherence (IA)] and all vital parameters [complete adherence (CA)] and defined as ratio of the number of days of measurements taken divided by the number of days of possible measurements. All data and group differences were analysed descriptively (mean ± SD) and by analysis of variance and t-test. Survey response rate was 79.7%. Patients were satisfied with the programme and device usability. CA was 89.1 ± 14.1%, consistently high over the study course and independent of severity of disease (left ventricular ejection fraction, N terminals pro brain natriuretic peptide, New York Heart Association). Lower IA was found with patients <70 years and prior to unplanned cardiovascular (CV) hospitalizations (difference by -5.2 ± 20.5%) and after unplanned CV hospitalizations compared with the entire study period (lower by -12.8 ± 24.7%). Patients from rural areas were found to have higher CA than patients from urban regions. CONCLUSIONS: With user-friendly devices, pre-interventional patient training, regular patient contact and close cooperation between primary physicians and telemedical centre, a long-lasting high adherence and satisfaction could be achieved. A change in adherence might detect health deterioration and indicate the need to intensify RPM.

[Telemedicine in chronic heart failure-From clinical studies to standard care]. / Telemedizin bei chronischer Herzinsuffizienz ­ von klinischen Studien zur Regelversorgung.

Telemedicine has the potential to solve many current and especially future challenges in medical care. Using the example of heart failure (HF), the transition of telemedicine from clinical studies to standard care is presented. In patients with chronic HF, randomized controlled trials have shown that telemedicine-based care leads to a reduction in mortality and cardiovascular morbidity. Based on these data, the Federal Joint Committee (G-BA) decided that for the first time a digital method should be introduced into standard care for high-risk patients with reduced left ventricular ejection fraction. In the future, this group of patients will be entitled to telemedical care using active rhythm devices or noninvasive measuring devices. The indications are assessed by the primary treating physician (PBA), who works together with a telemedicine center (TMZ) managed through cardiology that receives daily telemetric data and notifies the PBA of abnormal findings. Alternatively, a cardiologist PBA with an associated TMZ infrastructure can also provide telemedical care. In the future, advanced technologies such as artificial intelligence or mobile communication standard 5G will help to make telemedicine both widely available and usable for alternative sensor technology.

Cost-effectiveness of noninvasive telemedical interventional management in patients with heart failure: health economic analysis of the TIM-HF2 trial.

BACKGROUND: Noninvasive remote patient management (RPM) in patients with heart failure (HF) has been shown to reduce the days lost due to unplanned cardiovascular hospital admissions and all-cause mortality in the Telemedical Interventional Management in Heart Failure II trial (TIM-HF2). The health economic implications of these findings are the focus of the present analyses from the payer perspective. METHODS AND RESULTS: A total of 1538 participants of the TIM-HF2 randomized controlled trial were assigned to the RPM and Usual Care group. Health claims data were available for 1450 patients (n = 715 RPM group, n = 735 Usual Care group), which represents 94.3% of the original TIM-HF2 patient population, were linked to primary data from the study documentation and evaluated in terms of the health care cost, total cost (accounting for intervention costs), costs per day alive and out of hospital (DAOH), and cost per quality-adjusted life year (QALY). The average health care costs per patient year amounted to € 14,412 (95% CI 13,284-15,539) in the RPM group and € 17,537 (95% CI 16,179-18,894) in the UC group. RPM led to cost savings of € 3125 per patient year (p = 0.001). After including the intervention costs, a cost saving of € 1758 per patient year remained (p = 0.048). CONCLUSION: The additional noninvasive telemedical interventional management in patients with HF was cost-effective compared to standard care alone, since such intervention was associated with overall cost savings and superior clinical effectiveness.

Digital preventive measures for arterial hypertension (DiPaH) - a mixed-methods study protocol for health services research.

Introduction: Digital health measures promise to further improve the quality of cardiovascular care but have not yet been widely implemented in routine care. The research project Digital preventive measures for arterial hypertension (DiPaH) will systematically identify structural and individual factors in different stakeholders that influence the use of digital preventive measures in patients with arterial hypertension in Germany. Special focus is given to remote and sparsely populated areas, the age-specific impact, as well as influence of digital health literacy. Methods and analysis: The DiPaH project is an exploratory cross-sectional study with a mixed-methods design, in which written surveys and interviews with patients and physicians will be conducted. In addition, secondary data from a health insurance company will be analyzed. In module 1, individuals from the database of the health insurance company with confirmed arterial hypertension will be interviewed (1,600 questionnaires, 30 interviews). Module 2 includes users of digital prevention offers and apps (400 questionnaires, 40 interviews) and in module 3, family physicians and cardiologists will be interviewed (400 questionnaires, 40 interviews). In a final module, the overall results will be analyzed and recommendations for interventions in clinical care will be derived. Discussion: The DiPaH project will contribute to a patient-oriented and demand-based improvement of arterial hypertension prevention services in health care. Challenges and barriers will be analyzed and the respective target groups identified based on their prevention needs and social characteristics to enable a patient-centered implementation of digital prevention of arterial hypertension and cardiovascular services in general, and finally to improve cardiovascular outcomes.

Mortality and morbidity 1 year after stopping a remote patient management intervention: extended follow-up results from the telemedical interventional management in patients with heart failure II (TIM-HF2) randomised trial.

BACKGROUND: The Telemedical Interventional Management in Heart Failure II (TIM-HF2) trial showed that, compared with usual care, a structured remote patient management (RPM) intervention done over 12-months reduced the percentage of days lost due to unplanned cardiovascular hospitalisations and all-cause death. The aim of the study was to evaluate whether this clinical benefit seen for the RPM group during the initial 12 month follow-up of the TIM-HF2 trial would be sustained 1 year after stopping the RPM intervention. METHODS: TIM-HF2 was a prospective, randomised, multicentre trial done in 43 hospitals, 60 cardiology practices, and 87 general practitioners in Germany. Patients with heart failure, New York Heart Association functional class II or III, and who had been hospitalised for heart failure within 12 months before randomisation were randomly assigned to either the RPM intervention or usual care. At the final study visit (main trial), the RPM intervention was stopped and the 1 year extended follow-up period started, which lasted 1 year. The primary outcome was percentage of days lost due to unplanned cardiovascular hospitalisations and all-cause mortality. Analyses were done using the intention-to-treat principle. This trial is registered with ClinicalTrials.gov, number NCT01878630. FINDINGS: Between Aug 13, 2013, and May 12, 2017, 1538 patients were enrolled (765 to the remote patient management group and 773 to the usual care group) in the main trial. 671 of 765 patients in the remote patient management group and 673 of 773 in the usual care group completed the main trial and started the extended follow-up period up to 1 year later. In the extended follow-up period, the percentage of days lost due to unplanned cardiovascular hospital admissions and all-cause mortality did not differ significantly between groups weighted mean 5·95% [95% CI 4·59-7·31] in the RPM group vs 6·64% [95% CI 5·19-8·08] in the usual care group [rate ratio 0·79; 95% CI 0·78-1·21]). However, when data from the main trial and the extended follow-up period were combined, the percentage of days lost due to unplanned cardiovascular hospitalisation or all-cause death was significantly less in patients allocated to the RPM group (382 [50%] of 765; weighted mean 9·28%; 95% CI 7·76-10·81) than in the UC group (398 [51%] of 773; 11·78%; 95% CI 10·08-13·49; ratio of weighted average 0·79; 95% CI 0·62-1·00; p=0·0486). INTERPRETATION: The positive effect of our RPM intervention on morbidity and mortality over the course of the main trial was no longer observed 1 year after stopping the RPM intervention. However, because the TIM-HF2 trial was not powered to show significance during the extended follow-up period, our results are exploratory and require further research.

[German recommendations on lung and thoracic ultrasonography in patients with COVID-19]. / Empfehlungen zur Lungen- und Thoraxsonographie bei Patienten mit COVID-19-Erkrankung.

Lung and chest ultrasound are further examination modalities in addition to computed tomography and laboratory diagnostics in patients with COVID-19. It extends the clinical-physical examination because it can examine lung surface sensitively. Lung surface pattern changes have been found in sonograms of patients with COVID-19 pneumonia and during the course of the disease. German specialist societies of clinical acute, emergency and intensive care medicine as well as imaging, which are concerned with the care of patients with SARS-CoV­2 infection and COVID-19, have coordinated recommendations for lung and thorax sonography. This document has been created within a transparent process, led by the German Society of Interdisciplinary Emergency and Acute Medicine e. V. (DGINA), and worked out by an expert panel and delegates from the societies. Sources of the first 200 cases were summarized. Typical thorax sonographic findings are presented. International sources or standards that were available in PubMed until May 24, 2020 were included. Using case studies and multimedia content, the document is intended to not only support users but also demonstrate quality features and the potential of chest and lung sonography. The German Society for Ultrasound in Medicine (DEGUM) is carrying out a multicenter study (study coordination at the TU Munich).
