Reduced rate of admissions for acute coronary syndromes during the COVID-19 pandemic: an observational analysis from a tertiary hospital in Germany.

backgroundSeveral observational studies have suggested a worrying reduction in hospitalisations for acute coronary syndromes in the emergency cardiology department in the last few months all over the world. The aim of the present study is to assess the impact of the current COVID-19 health crisis on admission for acute coronary syndrome (ACS) in the cardiology department of a tertiary general hospital in Germany with a COVID-19 ward. METHODS AND

resultsThe authors retrieved clinical data evaluating consecutive patients with ACS admitted to their emergency cardiology department. Data from January to June 2020, as well as for a 5-week period corresponding to this year's COVID-19 outbreak in south-west Germany (23rd March-26th April), were analysed and compared to data from equivalent weeks in the previous 2 years. A trend of reduction in admissions for ACS was observed from the beginning of the outbreak in the region at the end of March 2020. This trend continued and even intensified after a fall in COVID-19 cases in the area; the number of ACS patients in April 2020 was 25% and in June 29% lower than in January 2020 (p-value for linear trend <0.001). An even more consistent reduction was observed as compared with the equivalent weeks in the previous 2 years (38% and 30% lower than in 2019 and 2018, respectively; p = 0.009).

conclusionsThe COVID-19 health and social crisis has caused a worrying trend of reduced cardiological admissions for ACS, without evidence of a decrease in its incidence. Understanding and counteracting the causes appears to be crucial to avoiding major long-term consequences for healthcare systems worldwide.
