Education curriculum assessment for teaching electrocardiography: Rationale and design for the prospective, international, randomized controlled EDUCATE trial.

BACKGROUND: Electrocardiogram (ECG) interpretation training is a fundamental component of medical education across disciplines. However, the skill of interpreting ECGs is not universal among medical graduates, and numerous barriers and challenges exist in medical training and clinical practice. An evidence-based and widely accessible learning solution is needed. DESIGN: The EDUcation Curriculum Assessment for Teaching Electrocardiography (EDUCATE) Trial is a prospective, international, investigator-initiated, open-label, randomized controlled trial designed to determine the efficacy of self-directed and active-learning approaches of a web-based educational platform for improving ECG interpretation proficiency. Target enrollment is 1000 medical professionals from a variety of medical disciplines and training levels. Participants will complete a pre-intervention baseline survey and an ECG interpretation proficiency test. After completion, participants will be randomized into one of four groups in a 1:1:1:1 fashion: (i) an online, question-based learning resource, (ii) an online, lecture-based learning resource, (iii) an online, hybrid question- and lecture-based learning resource, or (iv) a control group with no ECG learning resources. The primary endpoint will be the change in overall ECG interpretation performance according to pre- and post-intervention tests, and it will be measured within and compared between medical professional groups. Secondary endpoints will include changes in ECG interpretation time, self-reported confidence, and interpretation accuracy for specific ECG findings. CONCLUSIONS: The EDUCATE Trial is a pioneering initiative aiming to establish a practical, widely available, evidence-based solution to enhance ECG interpretation proficiency among medical professionals. Through its innovative study design, it tackles the currently unaddressed challenges of ECG interpretation education in the modern era. The trial seeks to pinpoint performance gaps across medical professions, compare the effectiveness of different web-based ECG content delivery methods, and create initial evidence for competency-based standards. If successful, the EDUCATE Trial will represent a significant stride towards data-driven solutions for improving ECG interpretation skills in the medical community.

High-Sensitivity Troponin T For The Risk Assessment Of Patients With Acute Atrial Fibrillation.

Elevations of high-sensitivity troponin T (Hs-TnT) in the setting of acute atrial fibrillation (AF) are not clearly understood. This study evaluated factors associated with these elevations and its prognostic implication. We prospectively included 413 consecutive patients who presented to our institution with acute AF. The median Hs-TnT on admission was 12 ng/l and 39.4% had values above the 99th percentile. At 1-year, AF recurrence occurred in 38.3% of patients, and MACE in 5.6%. Hs-TnT levels were not associated with AF reversion (p 0.869) or with 1-year AF recurrence (p 0.132) but they were with MACE (12 vs 24 ng/l, p 0.001). Thus, Hs-TnT was a strong predictor of MACE (HR 3.486, 95% CI 1.256-5.379, p 0.009) in this population. In conclusion, Hs-TnT elevation was frequently observed in patients with acute AF, and although it was not associated with AF reversion or recurrence, it was highly predictive of MACE at 1-year.

Ambulatory External Electrocardiography Monitoring: Holter, Extended Holter, Mobile Cardiac Telemetry Monitoring.

Ambulatory external electrocardiography (AECG) monitoring is effective as an evidence-based diagnostic tool when suspicion for cardiac arrhythmia is high. Multiple modalities of AECG monitoring exist, with unique advantages and limitations that predict effectiveness in a variety of clinical settings. Knowledge of these characteristics allows appropriate use of AECG, maximizing patient adherence, diagnostic yield, and cost-effectiveness. In addition, new technology has allowed the development of a modern generation of devices that offer increased efficacy and functionality compared with Holter monitors.

Ambulatory Patients with Cardiometabolic Disease and Without Evidence of COVID-19 During the Pandemic. The CorCOVID LATAM Study.

Background: SARS-CoV-2 pandemic has modified the cardiovascular care of ambulatory patients. The aim of this survey was to study changes in lifestyle habits, treatment adherence, and mental health status in patients with cardiometabolic disease, but no clinical evidence of COVID-19. Methods: A cross-sectional survey was conducted in ambulatory patients with cardiometabolic disease using paper/digital surveys. Variables investigated included socioeconomic status, physical activity, diet, tobacco use, alcohol intake, treatment discontinuation, and psychological symptoms. Results: A total of 4,216 patients (50.9% males, mean age 60.3 ± 15.3 years old) from 13 Spanish-speaking Latin American countries were enrolled. Among the study population, 46.4% of patients did not have contact with a healthcare provider, 31.5% reported access barriers to treatments and 17% discontinued some medication. Multivariate analysis showed that non-adherence to treatment was more prevalent in the secondary prevention group: peripheral vascular disease (OR 1.55, CI 1.08-2.24; p = 0.018), heart failure (OR 1.36, CI 1.05-1.75; p = 0.017), and coronary artery disease (OR 1.29 CI 1.04-1.60; p = 0.018). No physical activity was reported by 38% of patients. Only 15% of patients met minimum recommendations of physical activity (more than 150 minutes/week) and vegetable and fruit intake. Low/very low income (45.5%) was associated with a lower level of physical activity (p < 0.0001), less fruit and vegetables intake (p < 0.0001), more tobacco use (p < 0.001) and perception of depression (p < 0.001). Low educational level was also associated with the perception of depression (OR 1.46, CI 1.26-1.70; p < 0.01). Conclusions: Patients with cardiometabolic disease but without clinical evidence of COVID-19 showed significant medication non-adherence, especially in secondary prevention patients. Deterioration in lifestyle habits and appearance of depressive symptoms during the pandemic were frequent and related to socioeconomic status.

Gender Equity Imbalance in Cardiology Scientific Sessions in the Americas.

Women remain largely under-represented in cardiology worldwide. This is especially reflected in scientific sessions where panelists have a male preponderant representation. The amount of gender equity in cardiology during scientific activities in the American continent is unknown. The objective was to compare gender distribution of invited panelists in cardiology scientific sessions across the Americas during the period 2019-2020. A retrospective analysis of the cardiology scientific sessions held in North, Central, and South America was conducted. Sessions published on the official site and social networks of the national cardiology societies from January 1, 2019 to August 10, 2020 were included. Gender distribution and all-male panels were compared according to geographic regions, year, roles in the panel, and the main topics of the session. Seven hundred fifty-two scientific sessions were analyzed, with 3786 participants. The median participation of women was 20% (IQR 0%-37.5%). Specifically, the statistics reflected a female participation of 25% (IQR 0%-43.6%) in North America, 12.5% (IQR 0%-43%) in Central America and 10% (IQR 0%-33.3%) in South America (P < 0.0001). Women participation in the panels was different according to the main topic of the session (P < 0.0001), with higher proportions in topics such as cardiovascular diseases in women, congenital heart disease and cardio oncology. The frequency of all-male panels was 36.8% (CI95% 33.3-40.1), and it increased over time (2019: 30.9% vs 2020: 40.3%; P = 0.012). There is gender inequity in cardiology scientific sessions held in different regions of the Americas, with low participation of women especially in interventionist panels and leadership roles.

Assessment of Radiation-Induced Malfunction in Cardiac Implantable Electronic Devices.

BACKGROUND: Radiation therapy (RT) is a standard cancer treatment modality, and an increasing number of patients with cardiac implantable electronic devices (CIEDs) are being referred for RT. The goals of this study were as follows: (i) to determine the incidence of CIED malfunction following RT; (ii) to characterize the various types of malfunctions that occur; and (iii) to identify risk factors associated with CIED malfunction following RT. METHODS: A retrospective study of patients with CIEDs who received RT between 2007 and 2018 at 4 Canadian centres (Sunnybrook Health Sciences Centre, Kingston General Hospital, Hamilton Health Sciences Centre, and University of Ottawa Heart Institute) was conducted. Patients underwent CIED interrogation after completion of RT, to assess for late damage to the CIEDs. Data on demographics, devices, and RT were compared for the primary outcome of device malfunction. RESULTS: Of 1041 patients with CIEDs who received RT, 811 patients with complete data were included. Device malfunctions occurred in 32 of 811 patients (4%). The most common device malfunctions were reduced ventricular/atrial sensing (in 13 of 32 [41%]), an increase in lead threshold (in 9 of 32 [22%]), lead noise (in 5 of 32 [16%]), and electrical reset (in 2 of 32 [6%]). Higher beam energy (≥ 10 MV) was associated with malfunction (P < 0.0001). Radiation dose was not significantly different between the malfunction and non-malfunction groups (58.3 cGy vs 65 cGy, respectively, P = 0.71). CONCLUSIONS: Although RT-induced CIED malfunctions are rare (occurring in 4% of patients with a CIED who undergo RT), collaborative efforts between radiation oncologists and cardiac rhythm device clinics to optimize CIED monitoring are needed, to detect and manage CIED malfunctions. Malfunctions are more common in patients receiving higher-beam energy ( ≥ 10 MV ) RT.

CONTEXTE: La radiothérapie (RT) est une modalité standard de traitement du cancer, et un nombre croissant de patients porteurs de dispositifs cardiaques électroniques implantables (DCEI) doivent recevoir un traitement de RT. Les objectifs de cette étude étaient les suivants : (i) déterminer l'incidence d'une défaillance du DCEI après une RT; (ii) caractériser les différents types de défaillances qui se produisent; (iii) déterminer les facteurs de risque associés à la défaillance du DCEI après une RT. MÉTHODOLOGIE: Une étude rétrospective des patients avec un DCEI ayant reçu une RT entre 2007 et 2018 dans quatre centres canadiens (Sunnybrook Health Sciences Centre, Kingston General Hospital, Hamilton Health Sciences Centre et Institut de cardiologie de l'Université d'Ottawa) a été menée. Le DCEI des patients a été interrogé après la fin de la RT, pour en évaluer les dommages tardifs. Les données sur les caractéristiques démographiques, les dispositifs et la RT ont été comparées pour le paramètre d'évaluation principal, soit la défaillance du dispositif. RÉSULTATS: Sur les 1 041 patients avec un DCEI ayant reçu une RT, 811 patients avec des données complètes ont été inclus. Des défaillances du dispositif sont survenues chez 32 des 811 patients (4 %). Les défaillances les plus fréquentes du dispositif étaient une détection ventriculaire/atriale réduite (chez 13 des 32 patients [41 %]), une augmentation du seuil de la sonde (chez 9 des 32 patients [22 %]), un bruit provenant de la sonde (chez 5 des 32 patients [16 %]) et une réinitialisation électrique (chez 2 des 32 patients [6 %]). Une énergie de faisceau plus élevée (≥ 10 MV) était associée à une défaillance (p < 0,0001). La dose de rayonnement ne présentait pas de différence significative entre le groupe où une défaillance a été constatée et l'autre groupe (58,3 cGy vs 65 cGy, respectivement, p = 0,71). CONCLUSIONS: Bien que les défaillances du DCEI causées par la RT soient rares (survenant chez 4 % des patients avec un DCEI qui subissent une RT), une collaboration est nécessaire entre les radio-oncologues et les cliniques de dispositifs de gestion du rythme cardiaque, afin d'optimiser la surveillance du DCEI et de détecter et de gérer ces défaillances. Les défaillances sont plus fréquentes chez les patients recevant une énergie de faisceau plus élevée au moment de la RT ( ≥ 10 MV ) .

Neglected Tropical Diseases and Other Infectious Diseases Affecting the Heart. The NET-Heart Project: Rationale and Design.

Introduction: Neglected tropical diseases (NTDs) are a group of infections that are prevalent in many of the tropical and sub-tropical developing countries where poverty is rampant. NTDs have remained largely unnoticed in the global health agenda. There is a substantial gap between the burden of disease for NTDs in cardiovascular diseases (CVD) and research devoted to the affected populations. We created a Latin-American initiative with emerging leaders (EL) from the Interamerican Society of Cardiology (IASC) with the objective to perform multiple systematic reviews of NTDs and other infectious diseases affecting the heart: The NET-Heart Project. Objective: To describe the rationale and design considerations of the NET-Heart project. Methods: The NET-Heart Project is a collaborative work of the IASC EL program. The main objective of the NET-Heart project is to systematically evaluate the available evidence of NTDs and other infectious diseases and their cardiovascular involvement. As a secondary objective, this initiative aims to offer recommendations and potential diagnostic and therapeutic algorithms that can aid the management of cardiovascular complications of these infectious diseases. After an expert discussion 17 initial infectious diseases were selected, for each disease we created one working group. The project was structured in different phases: Systematic review, brainstorming workshops, analysis and results, manuscript writing and recommendations and evaluation of clinical implications. Conclusion: The NET-Heart project is an innovative collaborative initiative created to assess burden and impact of NTDs and other infectious diseases in CVD. NTDs can no longer be ignored and must be prioritised on the health and research agenda. This project aims to review in depth the evidence regarding cardiac compromise of these serious conditions and to propose strategies to overcome barriers for efficient diagnosis and treatment of cardiovascular complications.

Charting a course for cardiac electrophysiology training in Canada: the vital role of fellows in advanced cardiovascular care.

Canadian electrophysiology (EP) fellowship programs have evolved in an ad hoc fashion over 30 years. This evolution has occurred in many fields in medicine and is natural when innovators and pioneers attract research fellows who help change the status quo from predominantly research to a predominantly clinical application and focus. Fellows not only push their supervisors and their centres into new areas of inquiry but also function at the most advanced level to encourage and teach junior trainees and to provide examples of excellence to residents, medical students, and other health professionals. Funding for fellows has never been provided in the traditional way through the Ministry of Health or the Ministry of Advanced Education. Each Canadian centre has over the years found novel ways to fund fellowship programs, and many centres have used value-adds from procurement programs. These sources of funding are eroding as provincial government agencies are beginning to assume procurement responsibilities and local flexibility to fund fellowships is lost. In particular, provincial government agencies feel that valuable financial resources should be restricted to Canadian trainees only, despite the international consensus that fellowship is an essential time for advanced trainees to travel abroad to acquire a broad a range of experience, learn new techniques and approaches, make lifelong research connections, and hopefully return home with these skills and expertise. This article summarizes the long history of EP fellowship training in Canada, as well as EP fellowship experiences at home and abroad by Canadian electrophysiologists, in an attempt to contextualize these new realities.
