Initial Single-Center ST-Segment Elevation Myocardial Infarction Experience in New York Before and During the COVID-19 Pandemic.

ABSTRACT

BACKGROUND/PURPOSE: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a highly contagious and lethal virus, devastating healthcare systems throughout the world. Following a period of stability, the coronavirus disease 2019 (COVID-19) pandemic appears to be re-intensifying globally. As the virus continues to evolve, so does our understanding of its implications on ST-segment elevation myocardial infarction (STEMI). We sought to describe a single center STEMI experience at one of the epicenters during the COVID-19 pandemic. METHODS/MATERIALS We conducted a retrospective, observational study comparing STEMI patients during the pandemic period (March 1 to August 31, 2020) to those with STEMI during the pre-pandemic period (March 1 to August 31, 2019) at NYU Langone Hospital - Long Island, a tertiary-care center in Nassau County, New York. Additionally, we describe our subset of COVID-19 patients with STEMI during the pandemic. RESULTS: The acute myocardial infarction (AMI) team was activated for 183 patients during both periods. There were a similar number of AMI team activations during the pandemic period (n = 93) compared to the pre-pandemic period (n = 90). Baseline characteristics did not differ during both periods; however, infection control measures and additional investigation were required to clarify the diagnosis during the pandemic, resulting in a signal toward longer door-to-balloon times (95.9 min vs. 74.4 min, p = 0.0587). We observed similar inpatient length of stay (LOS) (3.6 days vs. 5.0 days, p = 0.0901) and mortality (13.2% vs. 9.2%, p = 0.5876). There were 6 COVID-19-positive patients who presented with STEMI, of whom 4 were emergently taken to the cardiac catheterization laboratory with successful percutaneous coronary intervention (PCI) performed in 3 patients. The 2 patients who were not offered primary PCI expired, as both were treated medically, one with thrombolytics. CONCLUSIONS: Our single-center study, in New York, at one of the epicenters of the pandemic, demonstrated a similar number of AMI team activations, mimicking the seasonal variability seen in 2019, but with a signal toward longer door-to-balloon time. Despite this, inpatient LOS and mortality remained similar.
