Figure 2:

Change in total procedure volumes by procedure type. Clustered bar graphs show the total procedure volumes for March 2019 (blue), April 2020 (red), and April 2021 (gray) by procedure type for U.S., non-U.S., and NUHIC facilities. Percentage change values represent the change in total summed procedures of all individual facilities in each category (in contrast to the median of the individual percentage change values shown in the central illustration) from 2019 to 2020 (bottom bracket) and 2019 to 2021 (top bracket). Nuclear stress testing includes stress SPECT and stress PET. PET infection testing is not shown in the figure because of the small sample size. CAC = coronary artery calcium, CCTA = coronary CT angiography, ECG = electrocardiography, Echo = echocardiography, ICA = invasive coronary angiography, NUHIC = non-U.S. high-income country, TEE = transesophageal echocardiography, TTE = transthoracic echocardiography.
