Infective Endocarditis in Belgium: Prospective Data in Adults from the ESC EORP European Endocarditis Registry.

(1) Background: infective endocarditis (IE) is a significant health concern associated with important morbidity and mortality. Only limited, often monocentric, retrospective data on IE in Belgium are available. This prospective study sought to assess the clinical characteristics and outcomes of Belgian IE patients in the ESC EORP European endocarditis (EURO-ENDO) registry; (2) Methods: 132 IE patients were identified based on the ESC 2015 criteria and included in six tertiary hospitals in Belgium; (3) Results: The average Belgian IE patient was male and 62.8 ± 14.9 years old. The native valve was most affected (56.8%), but prosthetic/repaired valves (34.1%) and intracardiac device-related (5.3%) IE are increasing. The most frequently identified microorganisms were S. aureus (37.2%), enterococci (15.5%), and S. viridans (15.5%). The most frequent complications were acute renal failure (36.2%) and embolic events (23.6%). Cardiac surgery was effectively performed when indicated in 71.7% of the cases. In-hospital mortality occurred in 15.7% of patients. Predictors of mortality in the multivariate analysis were S. aureus (HR = 2.99 [1.07-8.33], p = 0.036) and unperformed cardiac surgery when indicated (HR = 19.54 [1.91-200.17], p = 0.012). (4) Conclusion: This prospective EURO-ENDO ancillary analysis provides valuable contemporary insights into the profile, treatment, and clinical outcomes of IE patients in Belgium.

Extensive CArdioVAscular Characterization and Follow-Up of Patients Receiving Immune Checkpoint Inhibitors: A Prospective Multicenter Study.

BACKGROUND: The increasing use of immune checkpoint inhibitors (ICIs) in the treatment of both advanced and early stages of various malignancies has resulted in a substantial increase in the incidence of cardiovascular (CV) immune-related adverse events (irAEs). The current follow-up guidelines are based on anecdotal evidence and expert opinions, due to a lack of solid data and prospective studies. As many questions remain unanswered, cardiac monitoring, in patients receiving ICIs, is not always implemented by oncologists. Hence, an urgent need to investigate the possible short- and long-term CV effects of ICIs, as ICI approval is continuing to expand to the (neo)adjuvant setting. METHODS: We have initiated a prospective, multicenter study, i.e., the CAVACI trial, in which a minimum of 276 patients with a solid tumor, eligible for ICI treatment, will be enrolled. The study consists of routine investigations of blood parameters (troponin and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, in particular) and a thorough CV follow-up (electrocardiograms, transthoracic echocardiograms, and coronary calcium scoring) at fixed time points for a total period of two years. The primary endpoint is the cumulative incidence of troponin elevation in the first three months of ICI treatment, compared to baseline levels. Furthermore, secondary endpoints include incidence above the upper limit of normal of both troponin and NT-proBNP levels, evolution in troponin and NT-proBNP levels, the incidence of CV abnormalities/major adverse cardiac events, evaluation of associations between patient characteristics/biochemical parameters and CV events, transthoracic echocardiography parameters, electrocardiography parameters, and progression of coronary atherosclerosis. Recruitment of patients started in January 2022. Enrolment is ongoing in AZ Maria Middelares, Antwerp University Hospital, AZ Sint-Vincentius Deinze, and AZ Sint-Elisabeth Zottegem. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05699915, registered 26 January 2023.

Gender differences in risk factor management and pharmacological treatment among CHD patients: Belgian results of the EUROASPIRE IV and EUROASPIRE V surveys.

AIMS: The aim of this study was to provide an up-to-date overview of gender differences or similarities in risk factor control and medical management in the Belgian CHD population. METHODS: All analyses are based on the ESC EORP EUROASPIRE IV and EUROASPIRE V (European Survey Of Cardiovascular Disease Prevention And Diabetes) surveys. Patients between 18 and 80 years old, hospitalised for a first or recurrent coronary event, were included in the survey. RESULTS: Data were available for 10,519 patients, of which 23.9% were women. Women had a worse risk factor profile compared to men. Women were more physical inactive (OR = 1.31, 95% CI = 1.19-1.44), had a higher prevalence of obesity (OR = 1.37, 95% CI = 1.25-1.50) and had a worse LDL-C control (OR = 1.52, 95% CI = 1.36-1.70). Moreover, women were less likely to use ACE-I/ARBs (OR = 0.84, 95% CI = 0.76-0.94) and statins (OR = 0.79, 95% CI = 0.70-0.90). In addition, little gender differences were found in patients' risk factor awareness, except on cholesterol awareness. Women were more aware about their total cholesterol levels (OR = 1.37, 95% CI = 1.21-1.56). CONCLUSION: Despite little to no gender differences in the management of CHD patients, women still have a worse risk factor profile, both in Belgian and in other European high-income countries.

Impact of the initial clinical presentation on the outcome of patients with infective endocarditis.

BACKGROUND: Infective endocarditis (IE) is a life-threatening disease. Despite advancements in diagnostic methods, the initial clinical presentation of IE remains a valuable asset. Therefore, the impact of clinical presentation on outcomes and its association with microorganisms and IE localization were assessed herein. METHODS: This retrospective study included 183 patients (age 68.9 ± 14.2 years old, 68.9% men) with definite IE at two tertiary care hospitals in Belgium. Demographic data, medical history, clinical presentation, blood cultures, imaging data and outcomes were recorded. RESULTS: In-hospital mortality rate was 22.4%. Sixty (32.8%) patients developed embolism, 42 (23%) shock, and 103 (56.3%) underwent surgery during hospitalization. Shock at admission predicted embolism during hospitalization (odds ratio [OR] 2.631, 95% confidence interval [CI] 1.119-6.184, p = 0.027). A new cardiac murmur at admission predicted cardiac surgery (OR 1.949, 95% CI 1.007- -3.774, p = 0.048). Methicillin resistant Staphylococcus aureus predicted in-hospital mortality and shock (p = 0.005, OR 6.945, 95% CI 1.774-27.192 and p = 0.015, OR 4.691, 95% CI 1.348-16.322, respectively). Mitral valve and aortic valve IE predicted in-hospital death (p = 0.039, OR 2.258, 95% CI 1.043-4.888) and embolism (p = 0.017, OR 2.328, 95% CI 1.163-4.659), respectively. CONCLUSIONS: In this retrospective study, shock at admission independently predicted embolism during hospitalization in IE patients. Moreover, a new cardiac murmur at admission predicted the need for cardiac surgery. This emphasizes the importance of a comprehensive initial clinical evaluation in combination with imaging and microbiological data, in order to identify high-risk IE patients early.

Autonomic symptoms and associated factors in patients with chronic heart failure.

OBJECTIVE: Autonomic disorders are common in chronic illness, and their symptoms may restrict the daily functioning of patients. However, in chronic heart failure, extensive knowledge about autonomic symptoms is still lacking. This study aims to explore self-perceived autonomic symptoms, associated factors, and their relationship with health-related quality of life in chronic heart failure. METHODS: One hundred and twenty-four patients with documented chronic heart failure (men and women; 50-86 years) and 124 sex and age-matched controls participated in this study. The participants filled validated questionnaires about autonomic symptom profile (COMPASS 31), fatigue (CIS, Checklist for individual strength), anxiety and depression (HADS, Hospital Anxiety and Depression), and health-related quality of life (SF36). Non-parametric statistics were performed to analyse the data. RESULTS: Total score for autonomic symptoms was higher in chronic heart failure compared to controls [Median: 14.9; IQR: 6.2-25.1 vs. 7.3; 0-18; p < 0.001], especially for orthostatic hypotension [Median: 8; IQR: 0-16 vs. 0; 0-12; p < 0.001], vasomotor [Median: 0; IQR: 0-0 vs. 0; 0-0; p < 0.001] and secretomotor function [Median: 0; IQR: 0-4.2 vs. 0; 0-2.1; p = 0.013]. High scores for autonomic symptoms were moderate correlated with higher scores of fatigue, anxiety and depression (0.343 ≤ rs ≥ 0.420; p < 0.001) and with decreased health-related quality of life (-0.454; p < 0.01). CONCLUSION: Autonomic symptoms, especially for orthostatic intolerance, vasomotor and secretomotor subdomains, are prevalent and are associated with fatigue complaints and poor health-related quality of life in CHF.

Changes in lipid lowering medication and lipid levels over time in patients with stable coronary artery disease.

BACKGROUND/AIM: To provide longitudinal data on the evolution of lipid levels and the intake of lipid-lowering therapies in patients with stable coronary artery disease. METHODS: Single-centre retrospective study with inclusion of 350 patients with a first coronary artery event in 2014 or earlier and outpatient cardiac clinic follow-up in 2015 and 2019. Lipid levels were collected within a time frame of 3 months of their visits.This retrospective study protocol (2020.086) was approved by the ethical committee and by the Data Privacy Officer of AZ Maria Middelares Ghent. For this type of study, formal consent is not required, following local law and regulations. RESULTS: Average LDL levels were 82 (±26) mg/dl in 2015 and 70 (±24) mg/dl in 2019 (p < 0.001). Most patients included were already on statin treatment before inclusion in the trial (94%), with a significant increase in high-intensity statin use (45% vs. 58%) after a 5-year follow-up. At the same time, we observed a significant increase in ezetimibe use (in combination with statin therapy or in monotherapy) (8% vs. 22%) during follow-up. LDL ≤70 mg/dl was 34% in 2015 and 53% in 2019. LDL ≤55 mg/dl was 13% in 2015 and 28% in 2019. CONCLUSION: This study shows significant intensification of lipid-lowering therapy use during follow-up, and a significant lipid level lowering after 5-year follow-up, in an outpatient cardiac clinic follow-up. Further improvement in lipid control is still desirable, especially after the European Society of Cardiology recommend stricter lipid levels in the 2021 Prevention Guidelines.

Cardiac electrophysiology studies in mice via the transjugular route: a comprehensive practical guide.

Cardiac arrhythmias are associated with cardiovascular morbidity and mortality. Cardiac electrophysiology studies (EPS) use intracardiac catheter recording and stimulation for profound evaluation of the heart's electrical properties. The main clinical application is investigation and treatment of rhythm disorders. These techniques have been translated to the murine setting to open opportunities for detailed evaluation of the impact of different characteristics (including genetics) and interventions on cardiac electrophysiology and -pathology. Currently, a detailed description of the technique of murine transjugular EPS (which is the standard route of catheter introduction) is lacking. This article provides detailed information on EPS in mice via the transjugular route. This includes catheter placement, stimulation protocols, intracardiac tracing interpretation, artifact reduction, and surface ECG recording. In addition, reference values as obtained in C57BL/6N mice are presented for common electrophysiological parameters. This detailed methodological description aims to increase accessibility and standardization of EPS in mice. Ultimately, also human research and patient care may benefit from translation of the knowledge obtained in preclinical models using this technique.NEW & NOTEWORTHY Electrophysiology studies (EPS) allow in-depth evaluation of cardiac electrophysiology and -pathology. These techniques have been adapted to the murine setting for (translational) studies, mainly focusing on arrhythmogenesis. Despite the frequent application of EPS via the transjugular route, a thorough description of the technique is currently lacking. This article aims to function as a comprehensive guide, also elaborating (for the first time) on nonsurgical aspects such as catheter positioning, tracing artifacts, stimulation protocols, and reference values.

Impact of routine use of a cerebral protection device on the TAVR procedure and its short-term outcomes: a single-centre experience.

BACKGROUND: Stroke is a major concern in transcatheter aortic valve replacement (TAVR). The introduction of a cerebral protection devices may counteract the evolution towards minimally invasive TAVR. At this time, there is insufficient data to support the routine use of these devices. METHODS: We aimed to evaluate the outcome of the routine use of the Sentinel Cerebral protection system® (CPS) in patients undergoing TAVR, after completing a CT-based screening process for feasibility of Sentinel implantation. We report our initial experience with the routine implementation of the Sentinel CPS in all anatomically suitable patients undergoing TAVR. We retrospectively compared the procedural characteristics and outcomes between all TAVR patients treated with (n = 78) and without (n = 79) intended Sentinel. RESULTS: The Sentinel CPS could successfully be deployed in 99% of intended cases after CT feasibility screening. TAVR procedures with Sentinel CPS were not longer than procedures without Sentinel use (89 ± 20 versus 120 ± 50 min, p = 0.007). Sentinel CPS use was not associated with an increased risk of procedural complications. Stroke was observed in none (0%) of the Sentinel CPS patients, and in 6.3% of the non-Sentinel CPS patients (p = 0.05). The finding of stroke was associated with a high risk of early postprocedural mortality: 60% of stroke patients died within 3 months. CONCLUSION: Routine use of the Sentinel CPS in CT-screened TAVR patients is feasible with high procedural success, without significant adverse events and without counteracting the evolution towards minimally invasive TAVR. Clinically relevant stroke was observed in none of the Sentinel CPS patients.

Nuclear cardiac imaging for the diagnosis and management of heart failure: what can be learned from recent guidelines?

The aim of this review is to provide the clinical cardiologist and nuclear medicine specialist a brief overview of the currently accepted clinical use of cardiac nuclear imaging for the diagnosis and management of patients with heart failure based on recent (2012-2015) European Society of Cardiology (ESC) guidelines. We used the most recent ESC guidelines on heart failure, management of stable coronary artery disease, cardiac pacing, myocardial revascularisation, non-cardiac surgery and ventricular arrhythmias and sudden death. Nowadays cardiac nuclear imaging is useful in almost every step in heart failure from diagnostics to treatment. In first diagnosis of heart failure radionuclide imaging can provide information on ventricular function and volumes and nuclear imaging techniques provide accurate and reproducible left ventricular function assessment. In work out of the aetiology of the heart failure CMR, SPECT and PET imaging can demonstrate presence of inducible ischemia and myocardial viability. For prognostic information MIBG might be promising in the future. In treatment planning cardiac nuclear imaging is important to evaluate new angina and to assess accurate left ventricular ejection fraction before cardiac resynchronization therapy. Imaging stress testing is useful in the preoperative evaluation for non-cardiac surgery of heart failure patients. There is until now no recommended place for cardiac nuclear imaging in the follow-up of heart failure patients or prior to the initiation of cardiac rehabilitation.

SPECT-CCTA: guiding treatment in ischaemic heart disease.

Combining myocardial perfusion single photon emission computed tomography (SPECT-MPI) and coronary computed tomography angiography (CCTA) is an interesting hybrid imaging option in modern cardiovascular medicine. The integrated hybrid technique has a number of advantages compared to visual side-by-side analysis of the separate modalities. CT attenuation map can correct for attenuation artefacts and thus improve the diagnostic accuracy of SPECT-MPI. Moreover, the anatomical information of the CCTA and the perfusion map of SPECT-MPI allow for vessel-based correlation and culprit vessel identification. Combining SPECT-MPI with CCTA is an appealing tool in the work-up of complex ischaemic heart disease and might help determine the optimal treatment strategy. This case series illustrates the role of SPECT-CCTA in decision-making of revascularization strategy in complex ischaemic heart disease.

Prediction of recurrent event in patients with coronary heart disease: the EUROASPIRE Risk Model.

AIMS: Most patients with established atherosclerotic cardiovascular disease (CVD) are at very high risk for developing recurrent events. Since this risk varies a lot between patients there is a need to identify those in whom an even more intensive secondary prevention strategy should be envisaged. Using data from the EUROASPIRE IV and V cohorts of coronary heart disease (CHD) patients from 27 European countries, we aimed at developing and internally and externally validating a risk model predicting recurrent CVD events in patients aged < 75 years. METHODS AND RESULTS: Prospective data were available for 12 484 patients after a median follow-up time of 1.7 years. The primary endpoint, a composite of fatal CVD or new hospitalizations for non-fatal myocardial infarction (MI), stroke, heart failure, coronary artery bypass graft, or percutaneous coronary intervention (PCI), occurred in 1424 patients. The model was developed based on data from 8000 randomly selected patients in whom the association between potential risk factors and the incidence of the primary endpoint was investigated. This model was then validated in the remaining 4484 patients. The final multivariate model revealed a higher risk for the primary endpoint with increasing age, a previous hospitalization for stroke, heart failure or PCI, a previous diagnosis of peripheral artery disease, self-reported diabetes and its glycaemic control, higher non-high-density lipoprotein cholesterol, reduced renal function, symptoms of depression and anxiety and living in a higher risk country. The model demonstrated excellent internal validity and proved very adequate in the validation cohort. Regarding external validity, the model demonstrated good discriminative ability in 20 148 MI patients participating in the SWEDEHEART register. Finally, we developed a risk calculator to estimate risks at 1 and 2 years for patients with stable CHD. CONCLUSION: In patients with CHD, fatal and non-fatal rates of recurrent CVD events are high. However, there are still opportunities to optimize their management in order to prevent further disease or death. The EUROASPIRE Risk Calculator may be of help to reach this goal.

Toll-Like Receptors: Are They Taking a Toll on the Heart in Viral Myocarditis?

Myocarditis is an inflammatory disease of the heart with viral infections being the most common aetiology. Its complex biology remains poorly understood and its clinical management is one of the most challenging in the field of cardiology. Toll-like receptors (TLRs), a family of evolutionarily conserved pattern recognition receptors, are increasingly known to be implicated in the pathophysiology of viral myocarditis. Their central role in innate and adaptive immune responses, and in the inflammatory reaction that ensues, indeed makes them prime candidates to profoundly affect every stage of the disease process. This review describes the pathogenesis and pathophysiology of viral myocarditis, and scrutinises the role of TLRs in every phase. We conclude with directions for future research in this field.

A systematic literature review on the effects of exercise on human Toll-like receptor expression.

BACKGROUND: Toll-like receptors (TLRs) are a family of transmembrane pattern recognition receptors that are mainly expressed on immune cells. Recognition of various exogenous and endogenous molecular patterns activates the TLR signalling cascade, which orchestrates an inflammatory immune response. Dysfunctional immune responses, including aberrant TLR signalling, are increasingly implicated in the associations between sedentarism, chronic low-grade systemic inflammation and various non-communicable diseases. Conversely, exercise exerts anti-inflammatory effects, which could be conferred through its immunomodulatory properties, potentially affecting TLRs. This study aims to systematically review the effects of exercise on human TLR expression. METHOD: A systematic literature search of Pubmed, Embase, The Cochrane Library and SPORTDiscus for articles addressing the impact of exercise (as isolated intervention) on TLRs in humans was conducted, ending in February 2020. RESULTS: A total of 66 articles were included. The publications were categorised according to exercise modality and duration: acute resistance exercise (4 studies), acute aerobic exercise (26 studies), resistance training program (9 studies), aerobic training program (16 studies), combined (i.e. resistance and aerobic) training program (8 studies) and chronic exercise not otherwise classifiable (9 studies). Five articles investigated more than one of the aforementioned exercise categories. Several trends could be discerned with regard to the TLR response in the different exercise categories. Acute resistance exercise seemed to elicit TLR upregulation, whereas acute aerobic exercise had less activating potential with the majority of responses being neutral or, especially in healthy participants, downregulatory. Chronic resistance and combined exercise programs predominantly resulted in unaltered or decreased TLR levels. In the chronic aerobic exercise category, mixed effects were observed, but the majority of measurements demonstrated unchanged TLR expression. CONCLUSION: Currently published research supports an interplay between exercise and TLR signalling, which seems to depend on the characteristics of the exercise. However, there was large heterogeneity in the study designs and methodologies. Therefore, additional research is required to further corroborate these findings, to define its pathophysiological implications and to elucidate the mechanism(s) linking exercise to TLR signalling.

Proof-of-concept trial results of the HeartMan mobile personal health system for self-management in congestive heart failure.

This study tested the effectiveness of HeartMan-a mobile personal health system offering decisional support for management of congestive heart failure (CHF)-on health-related quality of life (HRQoL), self-management, exercise capacity, illness perception, mental and sexual health. A randomized controlled proof-of-concept trial (1:2 ratio of control:intervention) was set up with ambulatory CHF patients in stable condition in Belgium and Italy. Data were collected by means of a 6-min walking test and a number of standardized questionnaire instruments. A total of 56 (34 intervention and 22 control group) participants completed the study (77% male; mean age 63 years, sd 10.5). All depression and anxiety dimensions decreased in the intervention group (p < 0.001), while the need for sexual counselling decreased in the control group (p < 0.05). Although the group differences were not significant, self-care increased (p < 0.05), and sexual problems decreased (p < 0.05) in the intervention group only. No significant intervention effects were observed for HRQoL, self-care confidence, illness perception and exercise capacity. Overall, results of this proof-of-concept trial suggest that the HeartMan personal health system significantly improved mental and sexual health and self-care behaviour in CHF patients. These observations were in contrast to the lack of intervention effects on HRQoL, illness perception and exercise capacity.

Sexual counselling in patients with heart failure: Perceptions and current practice by healthcare providers in Flanders.

BACKGROUND: Although heart failure (HF) patients often consider sexual activity as an essential aspect of their quality of life (QoL) and are usually uncertain if it is safe to perform sexual activity, this topic is overall poorly addressed in clinical practice. AIMS: The aim of this study was to explore the perceptions and practices of Flemish caregivers. METHODS: Healthcare providers were recruited through convenience sampling and filled in an adapted version of the UNITE Sexual Counselling Instrument. Several relevant network structures in Flanders were used to distribute the questionnaires-online as well as on paper-to healthcare workers being involved in the care to HF patients. RESULTS: Results of 180 participants indicated that 51.5% of the healthcare providers have never provided sexual counselling in HF patients. Being male, having a masters' degree, having more than 10 years of experience in cardiovascular disease, working in an ambulatory care department and having more positive attitudes were independently associated with a higher provision of sexual counselling in practice. CONCLUSION: Although healthcare providers perceive it as their responsibility to discuss patients' sexual concerns, these issues are not often addressed in daily practice. Increasing knowledge in healthcare providers and specific practical training in providing information on sexual activity in HF patients are recommended. Further studies are needed to investigate how sexual counselling can be provided in agreement with HF patients' expectations and needs.

Feasibility and cost of FH cascade screening in Belgium (BEL-CASCADE) including a novel rapid rule-out strategy.

BACKGROUND: Familial hypercholesterolaemia (FH) is underdiagnosed in most countries. We report our first experience from a national pilot project of cascade screening in relatives of FH patients. METHODOLOGY: Participating specialists recruited consecutive index patients (IP) with Dutch Lipid Clinic Network (DLCN) score ≥6. After informed consent, the relatives were visited by the nurses to collect relevant clinical data and perform blood sampling for lipid profile measurement. FH diagnosis in the relatives was based on the DLCN and/or MEDPED FH (Make-Early-Diagnosis-to-Prevent-Early-Deaths-in-FH) criteria. RESULTS: In a period of 18 months, a total of 127 IP (90 with definite FH and 37 with probable FH) were enrolled in 15 centres. Out of the 270 relatives visited by the nurses, 105 were suspected of having FH: 31 with DCLN score >8, 33 with DLCN score 5-8 and 41 with MEDPED FH criteria. In a post-hoc analysis, another set of MEDPED FH criteria established in the Netherlands and adapted to Belgium allowed to detect FH in 51 additional relatives. CONCLUSION: In a country with no national FH screening program, our pilot project demonstrated that implementing a simple phenotypical FH cascade screening strategy using the collaboration of motivated specialists and two nurses, allowed to diagnose FH in 127 index patients and an additional 105 of their relatives over the two-year period. Newly developed MEDPED FH cut-offs, easily applicable by a nurse with a single blood sample, might further improve the sensitivity of detecting FH within families.

Peripheral arterial disease and intermittent claudication in coronary heart disease patients.

BACKGROUND AND AIM: Peripheral artery disease (PAD) is associated with an increased risk of fatal and non-fatal coronary heart disease (CHD). The aims of the this study were 1) to investigate the prevalence of PAD and suspected PAD in a large population of established CHD patients, and 2) to assess the prevalence and control of risk factors in these patients as well health-related quality of life. MATERIAL AND METHODS: In the EUROASPIRE V survey, 8243 patients with documented CHD were recruited from 27 ESC member countries and were invited to attend a study visit. Patients were investigated using questionnaires, in-depth interviews and a clinical examination. Intermittent claudication (IC) was assessed using the Edinburgh Claudication Questionnaire. Patients without previously diagnosed PAD were suspected of having PAD if they were found to have IC. RESULTS: Overall, 6.4% of the patients had already a confirmed diagnosis of PAD and another 6.3% were suspected of having PAD. Independent of age and gender, patients with previously diagnosed PAD were significantly more frequently current smokers, had the lowest smoking cessation rates, were less physically active, reported more often previously diagnosed diabetes and had significantly higher blood pressure levels, compared to patients without PAD. They had also significantly higher levels of serum triglycerides, lower HDL-C levels, and had more often renal insufficiency. In comparison with patients without PAD, those with suspected PAD demonstrated significantly higher smoking cessation rates but their obesity rates were significantly higher. In CHD patients with a history of PAD, the use of calcium channel blockers and diuretics was significantly higher than in patients without PAD. Compared to the latter group, the use of diuretics, anti-arrhythmics and anti-depressants in patients with suspected PAD was significantly higher. Moreover, patients with previously diagnosed PAD had significantly higher levels of anxiety and depression and reported a significantly worse health-related quality of life (HRQoL), in comparison with those without PAD. HRQoL levels were significantly reduced in patients with suspected PAD as well. CONCLUSION: In CHD patients without a previous diagnosis of PAD, IC is not infrequent. Diagnosed PAD was significantly associated with a worse CHD risk factor profile. Patients with known PAD as well as those with suspected PAD had a considerable loss of health-related quality of life. Therefore, physicians should consider to screen for IC in all their CHD patients.

Use of cardiac telerehabilitation during COVID-19 pandemic in Belgium.

BACKGROUND: The COVID-19 pandemic has forced many cardiac rehabilitation centres to focus more on the remote delivery of cardiac rehabilitation (CR) components. This increased focus and the lessons learned from this period could enhance the implementation of telerehabilitation and increase the participation in CR in Belgium. METHODS: We conducted a survey between April and May 2020 about the implementation of telerehabilitation services during the COVID-19 pandemic. The electronic questionnaire was sent via email to the heads of 42 Belgian CR centres. Three reminders via email were sent during the study period. RESULTS: 27 CR centres (64%) returned completed questionnaires after three mailings. 52% of the CR centres provided remote CR services during the lockdown due to the COVID-19 pandemic. All CR centres that provided remote CR services delivered exercise training. The most used medium to deliver the CR components were online videos (71%) followed by online information on the website (64%) and emails (64%). CONCLUSION: It is interesting that the COVID-19 pandemic has encouraged many CR centres to implement remote delivery of CR components. This can help to speed up the research and implementation of telerehabilitation in daily clinical practice. The COVID-19 pandemic could be the push for a large multicentre implementation study that could prove that telerehabilitation is feasible and effective in the Belgian setting.

The role of cardiac rehabilitation in vocational reintegration Belgian working group of cardiovascular prevention and rehabilitation position paper.

Cardiovascular disease is one of the main causes of morbidity and sick leave in Belgium, imposing a great socio-economic burden on the contemporary healthcare system and society. Cardiac rehabilitation is an evidence-based treatment strategy that not only improves the cardiac patients' health state but also holds promise so as to facilitate vocational reintegration in the society. This position paper was developed and endorsed by the Belgian Working Group of Cardiovascular Prevention and Rehabilitation. It provides an overview of the currently available Belgian data with regard to the role of cardiac rehabilitation in return to work after an initial cardiac event. It identifies the relevant barriers and facilitators of vocational integration of cardiac patients and summarises the contemporary Belgian legal and medical framework in this regard. Cardiac rehabilitation remains a primordial component of the post-acute event management of the cardiac patient, facilitating vocational reintegrating and thereby decreasing the pressure on social security. Despite the availability of a relevant legislative framework, there is a need for well-defined algorithms to assess readiness for return to work that can be used in daily clinical practice.
