A new test to diagnose heart failures better
Posted by evolvingwheel on November 29, 2007
With a special interest for remote healthcare and innovative diagnostics, this news couldn’t go past me. A group of researchers at the University of Leeds have come up with a new technique that helps to identify the difference between a heart attack potential and a chest pain due to other causes. Currently, when a patient lands up in the Er with chest pain, the physician administers a troponin test which can detect and evaluate heart injury and separate it from other chest pains. The test looks for troponin protein in the blood, which is generated when heart cells have died. However this test is not comprehensive and can give both false negatives and false positives. The predictor looks for the protein and only isolates between a scenario of real heart damage and a case of chest pain with no death of heart cells yet. It misses the spectrum in between.
A new test has been developed by the team that looks for a heart-type fatty acid-binding protein (H-FABP) which is released into the circulation following heart injury (myocardial ischemia). According to Alistair Hall, Professor of Clinical Cardiology at Leeds “The H-FABP test is a major advance on what we had before. It appears to be able to detect milder and earlier degrees of heart injury than do current tests which detect heart cell death.”
The uniqueness of the test lies in its ability to identify patients whose chest pains are an indication that they are susceptible to heart attack in the following weeks or months. The aspect of prevention makes this test a winner. It not only saves lives, but also saves money and unnecessary services. I will look forward to the eventual commercialization of such a test with an affordable price proposition. And then if such a test can be made portable and easy to administer at the point of care, i.e., homes.
