The bimodal "rise and fall" ACS curve overlapping COVID-19 pandemic peaks

ABSTRACT

Background: The COVID-19 outbreak harmed acute coronary syndromes. During the national lockdown in Italy, the fear of post-admission contagion translated into significant delays in seeking medical help among STEMI (ST-elevation myocardial infarction) patients. Objective and methods: Our analysis aimed to assess the ACS (Acute Coronary Syndromes) admissions during the pandemic, together with time to presentation and clinical outcomes compared to 2019 in a cardiovascular hub in Milan. Data of ACS patients admitted during the pandemic year 2020 were extracted by the hospital & rsquo;s database and compared to a historical cohort of patients admitted for the same clinical indications in 2019. Results: A total of 599 ACS cases were recorded in 2020 vs. 386 cases in 2019, with a net 55% increase, associated with late clinical presentations, a threefold increase in cardiogenic shock, and a more than two-fold higher mortality rate. Conclusions: The ultimate goal of this analysis is to preserve the life-saving focus on universal and prompt STEMI diagnosis and treatment, even in a time of dynamic global crisis.
