On Jun. 19, 2020, the COVID-19 pandemic in New York City caused a surge in out-of-hospital cardiac arrests and deaths, according to a study co-authored by researchers at Albert Einstein College of Medicine, Montefiore Health System, and the Fire Department of the City of New York (FDNY).

The study, published in JAMA Cardiology, found a three-fold increase in out-of-hospital non-traumatic cardiac-arrest cases in Mar. and Apr. 2020 compared to the same period in 2019.
