Can a simple heart ultrasound predict a dangerous lung complication?

This study aims to find out how often people develop a serious lung condition called chronic thromboembolic pulmonary hypertension (CTEPH) after having a blood clot in the lungs (pulmonary embolism). Researchers will use heart ultrasounds to look for early signs of heart strain in 100 adults who had a moderate-to-severe clot. The goal is to better predict who might develop CTEPH, so they can be monitored and treated earlier.
