Figure 1. Cardiac catheterization volume in the setting of ACS. (a) The number of cardiac catheterizations for each clinical indication separated by month. (b) The mean number of monthly cardiac catheterizations prior to the COVID-19 era compared with the number of cases during the COVID-19 era. Standard error bars are shown. *Statistically significant difference with a P value < 0.05. COVID-19: coronavirus disease 2019; ACS: acute coronary syndrome; UA: unstable angina; NSTEMI: non-ST-segment elevation myocardial infarction; STEMI: ST-segment elevation myocardial infarction; OHCA: out-of-hospital cardiac arrest.
