Daxor Corporation announced a new study in the prestigious Journal of Cardiac Failure demonstrating the importance and clinical utility of Daxor's BVA-100 blood test in heart failure (HF). The researchers showed that Daxor's BVA-100 was able to measure intravascular volume overload in heart failure patients -- a key metric targeted to successfully manage heart failure. Common surrogate markers and clinical evaluation to assess volume overload in contrast were shown to be ineffective at making a comparative clinically actionable measure, despite common usage in many hospitals.

The Journal of Cardiac Failure is the official peer reviewed journal of the Heart Failure Society of America and the Japanese Heart Failure Society. Data from this study was cited at the 2022 Annual Heart Failure Society of America meeting in a session focused on congestion measurement which called for the use of the BVA-100 diagnostic. Dr. Wayne Miller, Mayo Clinic, cited data from this study and concluded that "there are limitations to the use of the surrogates, if you need to know information about volume [in heart failure patients], you need to measure volume." The study titled, "Blood Volume Analysis and Hemodynamic Measures of Vascular Compliance in Patients with Worsening Heart Failure," assessed the relationship between blood volume, resting, and stress cardiovascular pressures in worsening HF.

Patients presenting to the hospital or outpatient clinic with clinical worsening HF underwent blood volume analysis measured with Daxor's BVA-100 diagnostic blood test, right heart catheterization, provocative testing including blood pressure measurement, leg raises, breathing techniques, and patient symptoms and physical exam findings.
