ABSTRACT
BACKGROUND:
Coronavirus disease 2019 (COVID-19) has forced dramatic changes to the healthcare systems throughout the world. Time-sensitive management of cardiovascular emergencies such as ST-elevation myocardial infarction (STEMI) has yet to be evaluated in the context of these new policies, particularly in so-called "hot spot" cities.METHODS:
We evaluated the early impact of the pandemic on STEMI performance in the Greater Montreal Area. A total of 167 patients from 3 different study periods were included. Patients presenting in the lockdown period from mid-March to mid-May 2020 (Group C, 53 patients) were compared to those from mid-March to mid-May 2019 (Group A, 60 patients) and the 2020 pre-COVID-19 period (Group B, 54 patients).RESULTS:
The number of STEMI admissions was unaffected during the lockdown. However, significantly longer delays between symptom onset and first medical contact (FMC) were noted (Group C 189.0 IQR [70.0, 840.0] min vs. Group A 103.0 IQR [42.5, 263.0] min vs. Group B 91.0 IQR [38.0, 235.5 min], P = 0.007). In contrast, additional safety protocols do not appear to have significantly affected delays between FMC and first intracoronary device activation (Group C 102 IQR [73.0, 133.0] min vs. Group A 104 IQR [87.0, 146.0] min vs. Group B 99.5 IQR [80.0, 150.0] min, P = 0.37). Patients that presented during the outbreak were more likely to be unstable with a higher incidence of Killip classes II-IV compared to groups A and B (28.3% vs. 18.3% vs. 5.6% respectively, P = 0.008). Worse in-hospital outcomes were also noted with a significantly higher rate of major adverse cardiac events (Group A 5.0% vs. Group B 11.1% vs. Group C 22.6%, P = 0.007).CONCLUSION:
During the lockdown period, many patients appear to have been reluctant to present to hospitals. This was associated with more unstable STEMI presentations and worse in-hospital course. Importantly, the health care system appears able to ensure timely acute cardiac care while ensuring that COVID-19 protocols are respected.Keywords
