Quality of healthcare and admission rates for acute cardiac events during COVID-19 pandemic: a retrospective cohort study on ST-segment-elevation myocardial infarction in China.

The impact of public health restrictions may lead to unexpected out-of-hospital deaths and compromised quality of healthcare for acute cardiac events. Delay or absence in patients should be continuously considered avoiding the secondary disaster of the pandemic. System delay should be modifiable for reversing the worst clinical outcomes from the COVID-19 outbreak, by coordination measures with focus on the balance between timely PCI procedure and minimising contamination of cardiac catheterisation rooms.
