ABSTRACT
The epidemiological necessity for distancing during the COVID-19 pandemic has resulted in postponement of non-emergent hospitalizations and increase use of telemedicine. The feasibility of virtual antiarrhythmic drug (AAD) loading specifically with digital QTc electrocardiographic monitoring (EM) in conjunction with telemedicine video visits is not well established. We tested the hypothesis that existing digital health technologies and virtual communication platforms could provide EM and support medically guided AAD loading for patients with symptomatic tachyarrhythmia in the ambulatory setting, while reducing physical contact between patient and healthcare system. A prospective pilot, case series was approved by the institutional ethics committee, entailing three subjects with symptomatic arrhythmia during the COVID-19 pandemic who were enrolled for virtual AAD loading at home. Clinicians met with participants twice daily via video visits conducted after QTc analysis (Kardia 6L mobile sensor) and telemetry review (Mobile Cardiac Outpatient Telemetry of silent arrhythmias). Participants received direct instruction to either terminate the study or proceed with the next single dose of AAD. All participants completed contactless loading of five AAD doses, without untoward event. Scheduled video visits allowed dialogue and participant counselling where decision-making was guided by remote review of EM. Participant adherence with transmissions and scheduled visits was 98.3%; a single electrocardiogram was delayed beyond the 2 hours of post-dose schedule. This virtual approach reduced overall expenditures based on retrospective comparison with previous AAD load hospitalizations. We found that a 'virtual hospitalization' for AAD loading with remote EM and twice-daily virtual rounding is feasible using existing digital health technologies.
ABSTRACT
BACKGROUND: The incidence of coronavirus disease 2019 (COVID-19) in patients with ST-segment elevation myocardial infarction (STEMI) has not been fully described. METHODS: All patients with STEMI undergoing primary percutaneous coronary intervention (PCI) in Ontario, Canada between March 1 and September 30, 2020 were included. Rates of positive COVID-19 tests from January 1, 2020 to the date of STEMI presentation were ascertained. For comparison, COVID-19 results were also evaluated in the adult Ontario population between January 1, 2020 and September 30, 2020, using provincial laboratory testing data. RESULTS: There were 3606 unique patients presenting with STEMI and receiving PCI in Ontario, Canada during the study period. Sixteen patients (0.44%) tested positive for COVID-19. The background infection rate among all 12,448,541 Ontario residents was similar, at 0.34%. CONCLUSIONS: The results of this population-based analysis suggest that proceeding with primary PCI with appropriate infection control practices is reasonable when community infection rates are low.
CONTEXTE: L'incidence de la maladie à coronavirus 2019 (COVID-19) chez les patients présentant un infarctus du myocarde avec élévation du segment ST (STEMI) n'a pas été entièrement décrite. MÉTHODOLOGIE: Tous les patients atteints de STEMI ayant subi une intervention coronarienne percutanée (ICP) primaire en Ontario (Canada) entre le 1er mars et le 30 septembre 2020 ont été inclus. Les taux de tests positifs à la COVID entre le 1er janvier 2020 et le moment de la présentation du STEMI ont été vérifiés. Aux fins de comparaison, les résultats des tests de dépistage de la COVID-19 ont également été évalués au sein de la population adulte de l'Ontario entre le 1er janvier 2020 et le 30 septembre 2020 au moyen des données des laboratoires provinciaux. RÉSULTATS: Pendant la période d'étude, 3 606 patients présentant un STEMI et ayant subi une ICP en Ontario (Canada) ont été recensés. Seize patients (0,44 %) ont reçu un résultat positif au test de dépistage de la COVID-19. Le taux d'infection parmi les 12 448 541 résidents de l'Ontario était similaire, soit 0,34 %. CONCLUSIONS: Les résultats de cette analyse populationnelle portent à penser qu'il est raisonnable de procéder à une ICP primaire avec des mesures appropriées de contrôle des infections lorsque les taux d'infection dans la collectivité sont faibles.
