ABSTRACT
SESSION TITLE: Outcomes Across COVID-19 SESSION TYPE: Rapid Fire Original Inv PRESENTED ON: 10/19/2022 11:15 am - 12:15 pm PURPOSE: Coronavirus disease 2019 (COVID-19) and influenza infections are associated with systemic inflammatory reactions that predispose to Takotsubo cardiomyopathy (TTS). Studies have investigated the epidemiology and clinical features of TTS in COVID-19 and influenza infection, however, there are limited data comparing TTS between patients with COVID-19 and influenza. METHODS: We searched PubMed/Medline, Web of Science, SCOPUS, EMBASE, and Google Scholar until November 1st, 2021, for case reports, case series, and observational cohort studies using these keywords: takotsubo syndrome/takotsubo cardiomyopathy, stress-induced cardiomyopathy, and broken heart syndrome combined with the terms COVID-19 and/or SARS-CoV-2, flu and/or influenza. All the published case reports included in the final analysis were in English and were categorized into patients with ‘COVID-19 + TTS’ and ‘Flu + TTS’. RESULTS: We identified 37 studies describing 64 patients with COVID-19+TTS and 10 case reports describing 10 patients with Flu + TTS. The mean age of patients in the COVID-19 + TTS was similar to the influenza group (69 years). Although women were more disproportionately affected by TTS in both groups, COVID-19 + TTS patients had a higher proportion of men than the Flu + TTS group (44% vs 30%) and previously reported incidence of TTS in men in the general population. Compared to patients with Flu + TTS, COVID-19 + TTS had a longer mean time from testing positive to developing TTS (7.3 days vs. 3.1 days), higher incidence rates of acute respiratory distress syndrome (77% vs. 40%), hypoxemic respiratory failure (86% vs. 60%), more likely to require invasive mechanical ventilation (63% vs. 40%) and higher in-hospital mortality rates (36%, n=23 vs 10%, n=1) CONCLUSIONS: Our systematic review highlights some important differences in the presentation and outcomes of TTS in patients with COVID-19 compared to seasonal influenza. Patients with COVID-19 + TTS had higher rates of respiratory complications and excess all-cause mortality compared to Flu + TTS. In contrast to the general population and patients infected with influenza, TTS tends to affect more men with COVID-19 infection. CLINICAL IMPLICATIONS: Hospitalized patients with COVID-19 who develop TTS appear to have a more severe disease course and poorer outcome compared to hospitalized patients with Flu+TTS. The study findings provide additional knowledge comparing complications between COVID-19 and influenza infections and may contribute to the continued efforts to manage the COVID-19 pandemic.
