This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study looks at two methods of giving the blood thinner heparin during a procedure called atrial fibrillation ablation. The goal is to see which method keeps the blood's clotting time in a safe range more often. Researchers reviewed records of 300 patients who had the procedure between 2018 and 2020. The findings could help reduce complications like stroke or bleeding.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
heparin
What this could lead to
If successful, this could point to a safer, more consistent way to give heparin during heart procedures, potentially reducing stroke and bleeding risks.
What could go wrong
This is a small, single-center retrospective study, not a large randomized trial. Results may not apply to all patients or hospitals.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This is a single-center and retrospective cohort study. The study will enroll patients above 20 years old and received RF ablation for AF from 2018 to the end of 2020. The baseline characteristics of the patients will be obtained from the electronic medical records, including age, sex, body weight, body height, risk factors of stroke, cardiac echo, laboratory data, and medications. Three experienced attending physicians are involved in the study. Two used the prespecified continuous infusion protocol to adjust heparin doses.
