New hemoglobin type discovered causing mock diagnosis of cardiac insufficiency

Until now it was assumed that diagnosis of low oxygen in usually oygen-rich areas of the blood vessels are evidence for a cardiac insufficiency . Now scientists from the university of Bonn, Germany found (more coincidentally) out that a new type of hemoglobin could have caused mock diagnosis of heart diseases in the past: when examining two patients (father and 4-year old son) with seemingly low oxygen saturation in the blood they diagnosed a cardiac insufficiency, although neither father nor the son showed symptoms.
Taking a closer look to the hemoglobin of both patients Dr. Berndt Zur (workgroup of Prof. Birgit Stoffel-Wagner, pediatric clinic, University of Bonn) found that father and son had an unknow type of hemoglobin which does not change color when un-or uploading oxygen as it has been known, being the background for the optical checking device-method of the pulse oxymeter.
In the future doctors will have to take an ever closer look to their measurements when dealing with cardiac insufficiency.
