RESUMEN
BACKGROUND: The COVID-19 pandemic has disrupted healthcare systems across the world. The rate of acute coronary syndrome (ACS) admissions during the pandemic has varied significantly. OBJECTIVES: The purpose of this study is to investigate the effect of the pandemic on ACS hospital admissions and to determine whether this is related to the number of COVID-19 cases in each country. METHOD: Search engines including PubMed, Embase, Ovid and Google Scholar were searched from December 2019 to the 15 September 2020 to identify studies reporting ACS admission data during COVID-19 pandemic months in 2020 compared with 2019 admissions. RESULTS: A total of 40 studies were included in this multistudy analysis. They demonstrated a 28.1% reduction in the rate of admission with ACS during the COVID-19 pandemic period compared with the same period in 2019 (total of 28 613 patients in 2020 vs 39 225 in 2019). There was a significant correlation between the absolute risk reduction in the total number of ACS cases and the number of COVID-19 cases per 100 000 population (Pearson correlation=0.361 (p=0.028)). However, the correlation was not significant for each of the ACS subgroups: non-ST-elevation myocardial infarction (STEMI) (p=0.508), STEMI (p=0883) and unstable angina (p=0.175). CONCLUSION: There was a significant reduction in the rate of ACS admission during the COVID-19 pandemic period compared with the same period in 2019 with a significant correlation with COVID-19 prevalence.

Although a reduction in hospital admissions of acute coronary syndromes (ACS) patients has been observed globally during the coronavirus disease 2019 (COVID-19) pandemic, clinical features of those patients have not been fully investigated. The aim of the present analysis is to investigate the incidence, clinical presentation, and outcomes of patients with ACS during the COVID-19 pandemic. We performed a retrospective analysis of consecutive patients who were admitted for ACS at our institution between March 1 and April 20, 2020 and compared with the equivalent period in 2019. Admissions for acute myocardial infarction (AMI) reduced by 39.5% in 2020 compared with the equivalent period in 2019. Owing to the emergency medical services (EMS) of our region, all time components of ST-elevated myocardial infarction care were similar during the COVID-19 outbreak as compared with the previous year's dataset. Among the 106 ACS patients in 2020, 7 patients tested positive for COVID-19. Higher incidence of type 2 myocardial infarction (29% vs. 4%, p = 0.0497) and elevated D-dimer levels (5650 µg/l [interquartile range (IQR) 1905-13,625 µg/l] vs. 400 µg/l [IQR 270-1050 µg/l], p = 0.02) were observed in COVID-19 patients. In sum, a significant reduction in admission for AMI was observed during the COVID-19 pandemic. COVID-19 patients were characterized by elevated D-dimer levels on admission, reflecting enhanced COVID-19 related thrombogenicity. The prehospital evaluation by EMS may have played an important role for the timely revascularization for STEMI patients.
