Heart valve patients test home blood monitoring
NCT ID NCT00506870
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether people with mechanical heart valves can safely check their own blood thinning levels at home instead of going to a lab. Over 900 adults who recently had valve surgery used a device to measure their INR (a clotting test) and had monthly lab checks. The goal was to see if self-monitoring is medically safe and costs less than standard care.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- INRatio or Coaguchek XS device for self-monitoring of INR
- What this could lead to
- If successful, this could show that self-monitoring is as safe and cheaper than regular lab visits for managing blood thinners after mechanical heart valve surgery.
- What could go wrong
- This trial is completed but results are not yet widely known. Self-monitoring requires training and may not suit all patients; errors in testing could lead to bleeding or clots.
