Key result
The COVID-19 pandemic was associated with up to a 25% decrease in STEMI cases and a drop to 28% in patients achieving guideline targets for first medical contact to balloon time at PCI sites.
Why the study?
To evaluate the impact of the COVID-19 pandemic and provincial emergency declarations on cardiac catheterization procedures for STEMI across Ontario.
Did the early COVID-19 pandemic affect STEMI case volumes and primary PCI treatment times in Ontario?

The early COVID-19 pandemic was associated with a significant decrease in STEMI presentations and substantial delays in primary PCI treatment times in Ontario.
BACKGROUND: In response to the COVID-19 pandemic, Ontario issued a declaration of emergency, implementing public health interventions on March 16, 2020. METHODS: We compared cardiac catheterization procedures for ST-elevation myocardial infarction (STEMI) between January 1 and May 10, 2020 to the same time frame in 2019. RESULTS: From March 16 to May 10, 2020, after implementation of provincial directives, STEMI cases significantly decreased by up to 25%. The proportion of patients who achieved guideline targets for first medical contact balloon for primary percutaneous coronary intervention (PCI) decreased substantially to 28% (median, 101 minutes) for patients who presented directly to a PCI site and to 37% (median, 149 minutes) for patients transferred from a non-PCI site, compared with 2019. CONCLUSIONS: STEMI cases across Ontario have been substantially affected during the COVID-19 pandemic.

Natarajan et al. (2020) conducted an observational in ST-elevation myocardial infarction (STEMI). COVID-19 pandemic timeframe vs. Same time frame in 2019 was evaluated on STEMI cases and proportion of patients achieving guideline targets for first medical contact to balloon time. The COVID-19 pandemic was associated with up to a 25% decrease in STEMI cases and a drop to 28% in patients achieving guideline targets for first medical contact to balloon time at PCI sites.
