Reductions in Each Cardiac Procedure Modality

The number of each procedure type in Asia (left) and in the rest of the world (ROW) (right) at March 2019, March 2020, and April 2020. All types of stress test modalities (exercise electrocardiography, stress echocardiography, nuclear stress imaging [single-photon emission computed tomography and positron emission tomography], and stress cardiac magnetic resonance [CMR]) are grouped together. Note the recovery of coronary computed tomography angiography (CTA) was observed in Asia but not in the rest of the world. CAC = coronary artery calcium; TEE = transesophageal echocardiography; TTE = transthoracic echocardiography.
