Emergency study on testing for blood clots in the lungs
Part of Heart & circulation, Lungs & breathing clinical trials.
This study looks at how doctors decide to test for pulmonary embolism (a blood clot in the lungs) in the emergency department. It helps understand what factors lead to testing, which could improve care for future patients.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are being seen in the emergency department for possible blood clot in the lungs (pulmonary embolism).
- You are 18 years or older.
- You have a D-dimer blood test done as part of your emergency visit.
- You live in Ontario and have a valid Ontario Health Insurance Plan (OHIP) card.
- You have not had imaging for blood clots (like a CT scan or ultrasound) in the past 30 days.
- You are not on blood thinners for a reason other than a blood clot.

This trial tests a new computer tool that helps doctors decide whether you likely have a blood clot in your leg or lung. If you have symptoms and are not already on blood thinners, you may be able to join.
This trial compares three treatments for an intermediate-high risk pulmonary embolism: a minimally invasive clot removal procedure (embolectomy), a low-dose clot-dissolving medication, or standard blood thinning (heparin). The goal is to see which approach works best to prevent worsening while reducing bleeding risks.
This real-world study compares different treatment approaches for pulmonary embolism (PE)—a serious blood clot in the lung arteries—in patients who are stable but at intermediate-to-high risk of complications. The goal is to understand which treatments work best and safest in everyday practice.
This study looks at how pressure measurements in the lung's main blood vessel can help doctors quickly identify patients with blood clots in the lungs (pulmonary embolism). Researchers will review past medical records and test results to see if this measurement is a useful tool for diagnosis.
This study compares two ways of checking for a pulmonary embolism (a blood clot in the lung) in the emergency room. It looks at the PERC score and the YEARS algorithm to see if they can help doctors decide when to do a D-dimer test and chest imaging, potentially reducing unnecessary tests.
This trial tests a treatment that uses ultrasound to guide a thin tube (catheter) to deliver clot-busting medicine directly into the blood clot in your lung. It may be an option for people whose clot is serious but not yet causing shock, and who have symptoms that started within the last two weeks.
