Purpose of review: The impact of the coronavirus disease 2019 (COVID-19) on the cardiovascular system has been highlighted since the very first weeks after the severe acute respiratory syndrome coronavirus 2 identification. We reviewed the influence of COVID-19 pandemic on cardiac arrest, both considering those occurred out of the hospital (OHCA) and in the hospital (IHCA).
Recent findings: An increase in OHCA incidence occurred in different countries, especially in those regions most burdened by the COVID-19, as this seems to be bounded to the pandemic trend. A change of OHCA patients' characteristics, with an increase of the OHCA occurred at home, a decrease in bystander cardiopulmonary resuscitation and automated external defibrillator use before Emergency Medical Service (EMS) arrival and an increase in non-shockable rhythms, have been highlighted. A dramatic drop in the OHCA patients' survival was pointed out in almost all the countries, regardless of the high or low-incidence of COVID-19 cases. Concerning IHCA, a reduction in survival was highlighted in patients with COVID-19 who sustained a cardiac arrest.
Summary: Cardiac arrest occurrence and survival were deeply affected by the pandemic. Informative campaigns to the population to call EMS in case of need and the re-allocation of the prehospital resources basing on the pandemic trend are needed to improve survival.
