Physiologists/scientists were the most frequently involved staff (81.9%). The primary indication for stress echocardiography was ischaemia evaluation (89.4%).

This evolution has paralleled advancements in disease diagnosis and facilitated the use of echocardiography as an important player in other disciplines such as cardio-oncology and interventional cardiology. Echocardiography research has made great progress, with new developments rapidly shaping the field. This continued innovation underscores the singular focus of improving patient care.
