Daxor Corporation announced new data validating the benefits of the Company's BVA-100 blood test (BVA) in improving survival for advanced heart failure patients with left ventricular assist device (LVAD). These data were presented at the International Society for Heart and Lung Transplant (ISHLT) Annual Meeting and Scientific Sessions – which brought together the world's leading experts in heart and lung transplant, held from April 27-30th, in Boston, MA. Implantable left ventricular assist devices have dramatically changed the face of advanced heart failure treatment and constitute a $350M annual market in the U.S. Patients suffering from persistent blood volume derangements have lower survival and decreased LVAD functionality but absent a BVA test go largely undiagnosed.

The study titled, “Intravascular Volume Derangement and Value of Blood Volume Analysis In Stable Ambulatory Patients with Advanced Heart Failure Supported with Left Ventricular Assist Device,” described variations in blood volume status (total blood and red blood cell volume) in 45 stable ambulatory patients with LVAD. Blood volume parameters were measured with Daxor's BVA-100 diagnostic blood test, which is a safe, 98% accurate, and objective test to directly quantify blood volume and composition. The study concluded that plasma volume abnormality was found in 75% of patients.

The data revealed that only 9% of these patients had normal blood volume results; 54% had significant red blood cell deficit and 12% had red blood cell excess. It was assumed from a clinical perspective and from LVAD device monitoring that there was no awareness or suspicion of significant alterations in intravascular volumes.
