Insights
Patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) had a low incidence of coronavirus disease 2019 (COVID-19). Proceeding with primary PCI is reasonable when community infection rates are low.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- The incidence of coronavirus disease 2019 (COVID-19) among patients with ST-segment elevation myocardial infarction (STEMI) is not well-documented.
- Understanding this overlap is crucial for patient management during the pandemic.
Purpose of the Study:
- To determine the incidence of COVID-19 in STEMI patients undergoing primary percutaneous coronary intervention (PCI).
- To compare COVID-19 rates in STEMI patients with the general population during the early pandemic.
Main Methods:
- Population-based retrospective study in Ontario, Canada (March 1 - September 30, 2020).
- Included STEMI patients undergoing primary PCI.
- Ascertained COVID-19 test positivity rates from January 1, 2020, to the date of STEMI presentation and compared with the general Ontario population.
Main Results:
- 3606 STEMI patients undergoing primary PCI were identified.
- Sixteen patients (0.44%) tested positive for COVID-19.
- This rate was similar to the background infection rate (0.34%) in the general Ontario population.
Conclusions:
- The incidence of COVID-19 among STEMI patients undergoing primary PCI was low during the study period.
- Primary PCI can be safely performed in STEMI patients with appropriate infection control measures, even with concurrent COVID-19 circulation.
- This supports the continuation of timely reperfusion therapy for STEMI during public health crises.
Background:
The incidence of coronavirus disease 2019 (COVID-19) in patients with ST-segment elevation myocardial infarction (STEMI) has not been fully described.
Methods:
All patients with STEMI undergoing primary percutaneous coronary intervention (PCI) in Ontario, Canada between March 1 and September 30, 2020 were included. Rates of positive COVID-19 tests from January 1, 2020 to the date of STEMI presentation were ascertained. For comparison, COVID-19 results were also evaluated in the adult Ontario population between January 1, 2020 and September 30, 2020, using provincial laboratory testing data.
Results:
There were 3606 unique patients presenting with STEMI and receiving PCI in Ontario, Canada during the study period. Sixteen patients (0.44%) tested positive for COVID-19. The background infection rate among all 12,448,541 Ontario residents was similar, at 0.34%.
Conclusions:
The results of this population-based analysis suggest that proceeding with primary PCI with appropriate infection control practices is reasonable when community infection rates are low.
