Abstract

Abstract: Background: T he COVID-19 pandemic led to an alteration of algorithms in emergency medicine, which may influence the management of patients with similar symptoms but underlying cardiovascular diseases. We evaluated key differential diagnoses to acute COVID-19 infection and the prevalence and the prognosis of myocardial injury in patients presenting for suspected COIVD-19 infection. Methods: This prospective observational study includes patients presenting with symptoms suggestive of COVID-19 infection during the pandemic. In patients without COVID-19, leading diagnoses was classified according to ICD-10. Myocardial injury was defined as elevated high-sensitivity Troponin I with at least one value above the 99th percentile upper reference limit and its prevalence together with 90-days mortality rate was compared in patients with vs without COVID-infection. Results: From 497 included patients (age 62.9 ± 17.2 years, 56 % male), 314 (63 %) were tested positive on COVID-19 based on PCR-testing, while another cause of symptom was detected in 183 patients (37 %). Cardiovascular diseases were the most frequent differential diagnoses (40 % of patients without COVID-19), followed by bacterial infection (24 %) and malignancies (16 %). Myocardial injury was present in 91 patients (COVID-19 positive: n = 34, COVID-19 negative: n = 57). 90-day mortality rate was higher in patients with myocardial injury (13.4 vs 4.6 %, p = 0.009). Conclusion: Cardiovascular diseases represent the most frequent differential diagnoses in patients presenting to a tertiary care emergency department with symptoms suggestive of an acute infection. Screening for cardiovascular disease is crucial in the initial evaluation of symptomatic patients during the COVID pandemic to identify patients at increased risk.
