Summary

This study looked at 750 people hospitalized for a COPD flare-up to find out how many also had a pulmonary embolism (a blood clot in the lung). Doctors used a standard set of tests, including a blood test and special scans, to check for clots. Participants were followed for 3 months to see if any clots appeared later. The goal was to understand how common this serious complication is in COPD patients.
