Heart valve patients test home blood monitoring
NCT ID NCT00506870
First seen Jun 05, 2026 · Last updated Jun 22, 2026 · Updated 3 times
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.
