Adherence to the European Society of Cardiology/European Society of Anaesthesiology recommendations on preoperative cardiac testing and association with positive results and cardiac events: a cohort study.

BACKGROUND: European Society of Cardiology/European Society of Anaesthesiology (ESC/ESA) guidelines inform cardiac workup before noncardiac surgery based on an algorithm. Our primary hypotheses were that there would be associations between (i) the groups stratified according to the algorithms and major adverse cardiac events (MACE), and (ii) over- and underuse of cardiac testing and MACE. METHODS: This is a secondary analysis of a multicentre prospective cohort. Major adverse cardiac events were a composite of cardiac death, myocardial infarction, acute heart failure, and life-threatening arrhythmia at 30 days. For each cardiac test, pathological findings were defined a priori. We used multivariable logistic regression to measure associations. RESULTS: We registered 359 MACE at 30 days amongst 6976 patients; classification in a higher-risk group using the ESC/ESA algorithm was associated with 30-day MACE; however, discrimination of the ESC/ESA algorithms for 30-day MACE was modest; area under the curve 0.64 (95% confidence interval: 0.61-0.67). After adjustment for sex, age, and ASA physical status, discrimination was 0.72 (0.70-0.75). Overuse or underuse of cardiac tests were not consistently associated with MACE. There was no independent association between test recommendation class and pathological findings (P=0.14 for stress imaging; P=0.35 for transthoracic echocardiography; P=0.52 for coronary angiography). CONCLUSIONS: Discrimination for MACE using the ESC/ESA guidelines algorithms was limited. Overuse or underuse of cardiac tests was not consistently associated with cardiovascular events. The recommendation class of preoperative cardiac tests did not influence their yield. CLINICAL TRIAL REGISTRATION: NCT02573532.

Expert opinion paper on cardiac imaging after ischemic stroke.

This expert opinion paper on cardiac imaging after acute ischemic stroke or transient ischemic attack (TIA) includes a statement of the "Heart and Brain" consortium of the German Cardiac Society and the German Stroke Society. The Stroke Unit-Commission of the German Stroke Society and the German Atrial Fibrillation NETwork (AFNET) endorsed this paper. Cardiac imaging is a key component of etiological work-up after stroke. Enhanced echocardiographic tools, constantly improving cardiac computer tomography (CT) as well as cardiac magnetic resonance imaging (MRI) offer comprehensive non- or less-invasive cardiac evaluation at the expense of increased costs and/or radiation exposure. Certain imaging findings usually lead to a change in medical secondary stroke prevention or may influence medical treatment. However, there is no proof from a randomized controlled trial (RCT) that the choice of the imaging method influences the prognosis of stroke patients. Summarizing present knowledge, the German Heart and Brain consortium proposes an interdisciplinary, staged standard diagnostic scheme for the detection of risk factors of cardio-embolic stroke. This expert opinion paper aims to give practical advice to physicians who are involved in stroke care. In line with the nature of an expert opinion paper, labeling of classes of recommendations is not provided, since many statements are based on expert opinion, reported case series, and clinical experience.

Endothelial function in cardiovascular medicine: a consensus paper of the European Society of Cardiology Working Groups on Atherosclerosis and Vascular Biology, Aorta and Peripheral Vascular Diseases, Coronary Pathophysiology and Microcirculation, and Thrombosis.

Endothelial cells (ECs) are sentinels of cardiovascular health. Their function is reduced by the presence of cardiovascular risk factors, and is regained once pathological stimuli are removed. In this European Society for Cardiology Position Paper, we describe endothelial dysfunction as a spectrum of phenotypic states and advocate further studies to determine the role of EC subtypes in cardiovascular disease. We conclude that there is no single ideal method for measurement of endothelial function. Techniques to measure coronary epicardial and micro-vascular function are well established but they are invasive, time-consuming, and expensive. Flow-mediated dilatation (FMD) of the brachial arteries provides a non-invasive alternative but is technically challenging and requires extensive training and standardization. We, therefore, propose that a consensus methodology for FMD is universally adopted to minimize technical variation between studies, and that reference FMD values are established for different populations of healthy individuals and patient groups. Newer techniques to measure endothelial function that are relatively easy to perform, such as finger plethysmography and the retinal flicker test, have the potential for increased clinical use provided a consensus is achieved on the measurement protocol used. We recommend further clinical studies to establish reference values for these techniques and to assess their ability to improve cardiovascular risk stratification. We advocate future studies to determine whether integration of endothelial function measurements with patient-specific epigenetic data and other biomarkers can enhance the stratification of patients for differential diagnosis, disease progression, and responses to therapy.

[Chronic coronary syndrome : New classification of stable coronary artery disease]. / Chronisches Koronarsyndrom : Neuklassifikation der stabilen koronaren Herzkrankheit.

In 2019 the European Society for Cardiology (ESC) published guidelines for the diagnosis and management of chronic coronary syndromes (CCS). Thus the term "stable coronary artery disease" is replaced by CCS. The newly introduced term is based on the current understanding of pathogenesis and clinical features of coronary artery disease (CAD) as well as therapeutic management. CCS defines CAD as a chronic process that can be influenced by lifestyle adjustments, pharmacological therapies and invasive interventions (percutaneous coronary intervention, coronary artery bypass grafting) with the aim of stabilization or regression. The present work provides an overview of various scenarios that involve CCS and diagnostic pathways to clarify potentially relevant CAD. It also highlights therapeutic management and secondary preventive procedures in accordance with the current recommendations of the ESC.

Validation of the new index of baroreflex function to identify neurogenic orthostatic hypotension.

BACKGROUND: According to expert opinion, orthostatic hypotension (OH) associated to a change in heart rate (ΔHR) less than 15 bpm suggests neurogenic OH (NOH). Recently, the ratio between HR and systolic blood pressure changes at 3 min of tilt test (ΔHR/ΔSBP) has been proposed as a better index than the ΔHR cut-off of 17 bpm. Our aim was to validate these indexes based on HR in an independent cohort of patients who performed cardiovascular reflex tests according to standardized procedures at our Institution. METHODS: We applied the HR indexes to all cardiovascular reflex tests that fulfilled the following criteria: (1) presence of classical OH at tilt test, (2) reliable Valsalva manoeuvre (VM), (3) absence of heart disease. We classified OH according to VM (absence of overshoot = NOH), and verified how many were correctly identified by ΔHR/ΔSBP (≤0.49 neurogenic) and ΔHR (≤17 and ≤15 neurogenic). RESULTS: We identified 369 tests with OH. Based on VM, 335 were NOH. The ΔHR/ΔSBP ≤ 0.49 identified NOH with a sensitivity of 91% and a specificity of 59%, the ΔHR ≤ 17 bpm with 88% sensitivity and 38% specificity, and the ΔHR ≤ 15 bpm with 84% sensitivity and 50% specificity. CONCLUSION: In our cohort, the ΔHR/ΔSBP ratio had a good sensitivity but a limited specificity to identify NOH. This easily applicable test may represent a valuable screening tool in a clinical setting to identify patients who need further detailed autonomic testing to confirm the neurogenic origin of OH.

Standardized definitions for evaluation of heart failure therapies: scientific expert panel from the Heart Failure Collaboratory and Academic Research Consortium.

The Heart Failure Academic Research Consortium is a partnership between the Heart Failure Collaboratory (HFC) and Academic Research Consortium (ARC), comprised of leading heart failure (HF) academic research investigators, patients, United States (US) Food and Drug Administration representatives, and industry members from the US and Europe. A series of meetings were convened to establish definitions and key concepts for the evaluation of HF therapies including optimal medical and device background therapy, clinical trial design elements and statistical concepts, and study endpoints. This manuscript summarizes the expert panel discussions as consensus recommendations focused on populations and endpoint definitions; it is not exhaustive or restrictive, but designed to stimulate HF clinical trial innovation.

Implementation of a systematic comprehensive geriatric assessment for elderly patients suspected of pulmonary hypertension.

BACKGROUND: The phenotype of patients seen for a suspicion of pulmonary hypertension has changed, with an increasing age and frequency of comorbidities. Selection of elderly patients, in whom a classical work-up is mandatory, is challenging. Comprehensive geriatric assessment (CGA) has modified the management of elderly patients with cancer. Pulmonary hypertension (PH) shares with cancer a functional impact and may evolve rapidly, depending on the group of PH. We assessed the impact of a systematic CGA in patients over 70 years old referred for a suspicion of PH. METHODS: A standardised CGA was performed on every patient older than 70 years old, referred for a PH suspicion, before considering invasive tests for diagnosis and treatment, between July 2014 and May 2019. Our primary aim was to describe the impact of CGA on the decision to stop or pursue the recommended diagnostic work-up for PH. RESULTS: Among the thirty-one patients evaluated [mean age 81,5 (72-91) years], a negative CGA leads to stop the diagnostic work-up in eleven patients. Among the nineteen remaining patients, sixteen had confirmed PH, with half being chronic thromboembolic pulmonary hypertension. CONCLUSIONS: Our study indicates that comprehensive geriatric assessment could be an excellent first screen for elderly patients referred for a PH suspicion. Involving a geriatric physician stopped the investigations in one third of patients. In patients with a favourable CGA, PH was confirmed in most of the cases, with chronic thromboembolic pulmonary hypertension being the first cause of PH.

[Evaluation of the use of a simulation software in the learning of cardiopulmonary auscultation in undergraduate medical students]. / Evaluation de l'utilisation d'un logiciel de simulation dans l'apprentissage de l'auscultation cardio-pulmonaire chez les étudiants en premier cycle d'études médicales.

INTRODUCTION: Medsounds™ software allows to create an auscultation learning platform, by providing real pre-recorded cardiopulmonary sounds on virtual chests. The study aimed at comparing the skills in cardiopulmonary auscultation between students who benefited from this platform and students who did not have access to it. METHODS: A controlled trial was conducted with 2nd year medical students randomised into three groups. Groups A, B and C received 10 h of cardiopulmonary clinical training. In addition, group B benefited from an online access to the educative platform, and group C had a demonstration of the platform during their clinical training, then an online access. The main outcome was a 3-point multiple-choice questionnaire based on 2 original case vignettes about the description of cardiopulmonary sounds. The secondary outcome was the faculty exam on high-fidelity cardiopulmonary simulator. RESULTS: Groups A and B included 127 students, and group C 117. Students in group C had a significantly higher score than those in group A (1.72/3 versus 1.48/3; p = 0.02), without difference between the groups B and C. Students who actually had a demonstration of the platform and used it at home had a higher score than those who did not use it (1.87 versus 1.51; p = 0.01). Students who had a demonstration of the platform before using it performed a better pulmonary examination on high-fidelity simulators. CONCLUSION: The supervised use of an online auscultation simulation software in addition to the traditional clinical training seems to improve the auscultation performances of undergraduated medical students.

Testing cardiovascular autonomic function in the COVID-19 era: lessons from Bologna's Autonomic Unit.

The coronavirus disease 2019 (COVID-19) pandemic has changed the way most medical procedures are performed. Autonomic units, as well as other healthcare sectors, are required to undergo a thorough reorganization of the protocols in order to guarantee the safety of patients and healthcare staff. Cardiovascular autonomic function testing (CAFT) is necessary in certain situations; however, it poses several concerns which need to be addressed. Here, we provide some practical advice based on current national and international health authorities' recommendations and our experience about how to perform CAFT during the COVID-19 emergency. We examine aspects regarding patients, healthcare staff, laboratory preparation, and test performance.

Management of valvular and structural heart diseases during the coronavirus disease 2019 pandemic: an expert opinion of the Working Group on Valvular Heart Diseases, the Working Group on Cardiac Surgery, and the Association of Cardiovascular Interventions of the Polish Cardiac Society.

The ongoing pandemic of coronavirus disease 2019 (COVID­19), caused by severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2), represents a major challenge for healthcare. The involvement of cardiovascular system in COVID­19 has been proven and increased healthcare system resources are redirected towards handling infected patients, which induces major changes in access to services and prioritization in the management of patients with chronic cardiovascular disease unrelated to COVID­19. In this expert opinion, conceived by the task force involving the Working Groups on Valvular Heart Diseases and Cardiac Surgery as well as the Association of Cardiovascular Intervention of the Polish Cardiac Society, modification of diagnostic pathways, principles of healthcare personnel protection, and treatment guidelines regarding triage and prioritization are suggested. Heart Teams responsible for the treatment of valvular heart disease should continue their work using telemedicine and digital technology. Diagnostic tests must be simplified or deferred to minimize the number of potentially dangerous aerosol­generating procedures, such as transesophageal echocardiography or exercise imaging. The treatment of aortic stenosis and mitral regurgitation has to be offered particularly due to urgent indications and in patients with advanced disease and poor prognosis. Expert risk stratification is essential for triage and setting the priority lists. In each case, an appropriate level of personal protection must be ensured for the healthcare personnel to prevent spreading infection and preserve specialized manpower, who will supply the continuing need for handling serious chronic cardiovascular disease. Importantly, as soon as the local epidemic situation improves, efforts must be made to restore standard opportunities for elective treatment of valvular heart disease and occluder­based therapies according to existing guidelines, thus rebuilding the state ­of ­the ­art cardiovascular services.

Nonrenal Complications of Contrast Media.

Injection of contrast media is the foundation of invasive and interventional cardiovascular practice. Iodine-based contrast was first used in the 1920s for urologic procedures and examinations. The initially used agents had high ionic and osmolar concentrations, which led to significant side effects, namely nausea, vomiting, and hypotension. Newer contrast agents had lower ionic concentrations and lower osmolarity. Modifications to the ionic structure and iodine content led to the development of ionic low-osmolar, nonionic low-osmolar, and nonionic iso-osmolar contrast media. Contemporary contrast agents are better tolerated and produce fewer major side effects.

2019 Italian Society of Cardiology Census on telemedicine in cardiovascular disease: a report from the working group on telecardiology and informatics.

Background: The aim of this study was to assess by a census supported by the Italian Society of Cardiology (Società Italiana di Cardiologia, SIC) the present implementation of telemedicine in the field of cardiovascular disease in Italy. Methods: A dedicated questionnaire was sent by email to all the members of the SIC: data on telemedicine providers, service provided, reimbursement, funding and organisational solutions were collected and analysed. Results: Reported telemedicine activities were mostly stable and public hospital based, focused on acute cardiovascular disease and prehospital triage of suspected acute myocardial infarction (prehospital ECG, always interpreted by a cardiologist and not automatically reported by computerised algorithms). Private companies delivering telemedicine services in cardiology (ECGs, ambulatory ECG monitoring) were also present. In 16% of cases, ECGs were also delivered through pharmacies or general practitioners. ICD/CRT-D remote control was performed in 42% of cases, heart failure patient remote monitoring in 37% (21% vital parameters monitoring, 32% nurse telephone monitoring). Telemedicine service was public in 74% of cases, paid by the patient in 26%. About half of telemedicine service received no funding, 17% received State and/or European Union funding. Conclusions: Several telemedicine activities have been reported for the management of acute and chronic cardiovascular disease in Italy. The whole continuum of cardiovascular disease is covered by telemedicine solutions. A periodic census may be useful to assess the implementation of guidelines recommendations on telemedicine.

Testing for Coronary Artery Disease in Older Patients With New-Onset Heart Failure: Findings From Get With The Guidelines-Heart Failure.

BACKGROUND: Current guidelines recommend evaluation for underlying heart disease and reversible conditions for patients with new-onset heart failure (HF). There are limited data on contemporary testing for coronary artery disease (CAD) in patients with new-onset HF. METHODS: We performed an observational cohort study using the Get With The Guidelines-Heart Failure registry linked to Medicare claims. All patients were aged ≥65 and hospitalized for new-onset HF from 2009 to 2015. We collected left ventricular ejection fraction (LVEF), prior HF history, and in-hospital CAD testing from the registry, as well as testing for CAD using claims from 90 days before to 90 days after index HF hospitalization. RESULTS: Among 17 185 patients with new-onset HF, 6672 (39%) received testing for CAD, including 3997 (23%) during the index hospitalization. Testing for CAD differed by LVEF: 53% in HF with reduced EF (LVEF ≤40%), 42% in HF with borderline EF (LVEF, 41%-49%), and 31% in HF with preserved EF (LVEF ≥50%). After multivariable adjustment, patients who received testing for CAD, compared with those who did not, were younger and more likely to be male, have a smoking history, have hyperlipidemia, and have HF with reduced ejection fraction or HF with borderline ejection fraction (all P<0.05). CONCLUSIONS: The majority of patients hospitalized for new-onset HF did not receive testing for CAD either during the hospitalization or in the 90 days before and after. The rates of testing for CAD were higher in patients with LVEF ≤40% though remained low. These data highlight an opportunity to improve care by identifying appropriate candidates for optimal CAD medical therapy and revascularization.

[ANMCO/SICI-GISE/SIC/SIECVI/SIRM Consensus document: Appropriateness of multimodality imaging in cardiovascular disease]. / Documento di consenso ANMCO/SICI-GISE/SIC/SIECVI/SIRM: Appropriatezza dell'imaging multimodale nelle patologie cardiovascolari.

The complexity of cardiovascular diseases has led to an extensive use of technological instruments and the development of multimodality imaging. This extensive use of different cardiovascular imaging tests in the same patient has increased costs and waiting times.The concept of appropriateness has changed over time. Appropriateness criteria address the need for specific cardiovascular imaging tests in well-defined clinical scenarios, and define the kind of cardiovascular imaging that is appropriated for each clinical scenario in different stages of the disease. The concept of appropriateness criteria has replaced the old idea of appropriate use criteria and reflects the increasing effort of the international Scientific Societies to create and review in a critical way the management of diagnostic tests used by clinicians.The aim of this Italian consensus document is to address the use of multimodality imaging in the diagnosis and management of the major cardiovascular clinical scenarios, taking into consideration not only the international guidelines and scientific documents already published, but also the reality of Italian laws as well as the various professional profiles involved in patient management and availability of technological diagnostic instruments.

Symptom perception in heart failure: a scoping review on definition, factors and instruments.

BACKGROUND: Symptom perception in heart failure has been identified as crucial for effective self-care that is a modifiable factor related to decreased hospital readmission and improved survival. AIMS: To review systematically the heart failure symptom perception literature and synthesise knowledge on definition, description, factors and instruments. METHODS: We conducted a scoping review including studies reporting patient-reported symptom perception in adults with heart failure. Structured searches were conducted in Medline, PubMed, Embase, CINAHL, PsychINFO, Web of Science, Cochrane, JBI and grey literature. Two authors independently reviewed references for eligibility. Data were charted in tables and results narratively summarised. RESULTS: The search yielded 3057 references, of which 106 were included. The definition of heart failure symptom perception comprised body listening, monitoring signs, recognising, interpreting and labelling symptoms, and furthermore awareness of and assigning meaning to the change. Symptom monitoring, recognition and interpretation were identified as challenging. Symptom perception facilitators include prior heart failure hospitalisation, heart failure self-care maintenance, symptom perception confidence, illness uncertainty and social support. Barriers include knowledge deficits, symptom clusters and lack of tools/materials. Factors with inconsistent impact on symptom perception include age, sex, education, experiences of living with heart failure, comorbidities, cognitive impairment, depression and symptom progression. One instrument measuring all dimensions of heart failure symptom perception was identified. CONCLUSION: Heart failure symptom perception definition and description have been elucidated. Several factors facilitating or hampering symptom perception are known. Further research is needed to determine a risk profile for poor symptom perception - which can then be taken into consideration when supporting heart failure self-care.

The Asia-Pacific Society of Cardiology (APSC) Expert Committee Consensus Recommendations for Assessment of Suspected Acute Coronary Syndrome Using High-Sensitivity Cardiac Troponin T in the Emergency Department.

The Asia-Pacific Society of Cardiology (APSC) high-sensitivity troponin T (hs-TnT) consensus recommendations and rapid algorithm were developed to provide guidance for healthcare professionals in the Asia-Pacific region on assessing patients with suspected acute coronary syndrome (ACS) using a hs-TnT assay. Experts from Asia-Pacific convened in 2 meetings to develop evidence-based consensus recommendations and an algorithm for appropriate use of the hs-TnT assay. The Expert Committee defined a cardiac troponin assay as a high-sensitivity assay if the total imprecision is ≤10% at the 99th percentile of the upper reference limit and measurable concentrations below the 99th percentile are attainable with an assay at a concentration value above the assay's limit of detection for at least 50% of healthy individuals. Recommendations for single-measurement rule-out/rule-in cutoff values, as well as for serial measurements, were also developed. The Expert Committee also adopted similar hs-TnT cutoff values for men and women, recommended serial hs-TnT measurements for special populations, and provided guidance on the use of point-of-care troponin T devices in individuals suspected of ACS. These recommendations should be used in conjunction with all available clinical evidence when making the diagnosis of ACS.

Historical reviews of the assessment of human cardiovascular function: interrogation and understanding of the control of skin blood flow.

Several techniques exist for the determination of skin blood flow that have historically been used in the investigation of thermoregulatory control of skin blood flow, and more recently, in clinical assessments or as an index of global vascular function. Skin blood flow measurement techniques differ in their methodology and their strengths and limitations. To examine the historical development of techniques for assessing skin blood flow by describing the origin, basic principles, and important aspects of each procedure and to provide recommendations for best practise. Venous occlusion plethysmography was one of the earliest techniques to intermittently index a limb's skin blood flow under conditions in which local muscle blood flow does not change. The introduction of laser Doppler flowmetry provided a method that continuously records an index of skin blood flow (red cell flux) (albeit from a relatively small skin area) that requires normalisation due to high site-to-site variability. The subsequent development of laser Doppler and laser speckle imaging techniques allows the mapping of skin blood flow from larger surface areas and the visualisation of capillary filling from the dermal plexus in two dimensions. The use of iontophoresis or intradermal microdialysis in conjunction with laser Doppler methods allows for the local delivery of pharmacological agents to interrogate the local and neural control of skin blood flow. The recent development of optical coherence tomography promises further advances in assessment of the skin circulation via three-dimensional imaging of the skin microvasculature for quantification of vessel diameter and vessel recruitment.

[Exercise testing: New guidelines]. / Nouvelles recommandations concernant la pratique des tests d'effort en cardiologie.

The GERS-P (Exercise Rehabilitation Sports Prevention Group of the French Society of Cardiology) has decided to update current guidelines regarding the practice of EKG stress tests. Since the last update dates from 1997, the GERS judged it necessary to integrate data from new works and advancements made in the last 20 years. Good clinical practices and safety conditions are better defined regarding the structure, location, material, staff competency, as well as convention with hospital structures. The diagnosis of coronary artery disease remains the principal indication for a stress test. Interpretation of the results is crucial - it must be multivariate and provide either a low, intermediate or strong probability of the existence of coronary lesions, taking into account the studied population (risk factors, age, sex and symptoms). We no longer have to talk about a "positive, negative or litigious" test. Several new indications for a stress test have been defined for the assessment of cardiac pathologies. With such indications, the use of gas expiration measurements is highly recommended in order to provide a precise prognosis for all the various cardiac pathologies : congenital, ischemic, valvular, cardiomyopathy, congestive heart failure, rhythm and conduction disorders, pacemaker fine-tuning, or pulmonary hypertension. Indications for stress tests and contraindications are defined according to different population subgroups, for instance : athletes, women, children, the elderly, asymptomatic patients, diabetics, hypertensive patients, peripheral arteritis disease patients, or in the context of a non-cardiac surgery pre-op visit. The new guidelines are considerably different from those dating from 1997 and further pinpoint the relevance and importance of an EKG stress test within the arsenal of complementary cardiologic exams. With the improvements made in providing diagnostic value in CAD, as well as better prognostic value for any underlying pathology, the indication for an EKG stress test has extended to all cardiovascular disease.

[ECG in sportsmen: Distinguishing the normal from the pathological]. / ECG du sportif : distinguer le normal du pathologique.

An ECG is recommended by the French Society of Cardiology in the screening of a competitive athlete. An intense and prolonged physical activity (>4 hours of intense sport/week) can lead to a physiological electric remodeling. In addition to physical activity (type, intensity, duration), the ECG should be interpreted according to the athlete's ethnicity and age. It is necessary to know the physiological modifications related to sport practice to avoid either false reassurances or the realization of unjustified additional examinations because of a wrong interpretation. The latest athlete ECG classification published in 2017 can be used to identify in which athlete additional tests are recommended (figure 1).
