Abstract

Objective: The COVID-19 pandemic has been associated with decreased incidence of acute coronary syndrome with worsened outcomes. Few studies have addressed the effects beyond the initial phases of the pandemic. This study elucidated the incidence, clinical characteristics, management, and outcomes of NSTEMI at a tertiary referral center from sample time periods of 2019–2022. Methods: This study included consecutive NSTEMI patients from March 14–May 9, 2019–2022. Variables included baseline characteristics, clinical features on arrival, management strategy, time parameters, and adverse outcomes. The primary outcome was defined as death, heart failure requiring diuretics, and/or sustained ventricular arrhythmia. Results: This study comprised 250 patients of whom 181 who were admitted during the COVID-19 outbreak. Baseline characteristics were similar among groups. There was a reduction in door-to-angiography time from 29 h in 2019 to 19 h in 2020 [p = 0.01] and 20 h in 2021 [p = 0.02]. PCI intervention increased from 31.8% in 2019% to 50.0% in 2020 [p = 0.05] and 54.7% in 2021 [p < 0.01]. Median length-of-stay (LOS) was reduced from 3 days in 2019 to 2 days in 2020 [p = 0.03]. There was no significant change in outcomes in COVID-19 cohorts compared to control year. Conclusions: NSTEMI patients during the first 2 years of the COVID-19 pandemic were associated with reduced door-to-angiography times and increased percutaneous coronary intervention (PCI), and patients in year one were associated with reduced LOS. This study suggests that NSTEMI may be managed more efficiently thus reducing hospital bed utilization and potential costs.
