Acute Heart Failure Mortality, Rehospitalizations Reduced With Blood Volume Measurement

Controlled study of BVA-100 blood volume analyzer showed 86 percent reduction in one-year mortality

Acute Heart Failure Mortality, Rehospitalizations Reduced With Blood Volume Measurement

November 2, 2018 — In a new study, acute heart failure patients who received individualized treatment by blood volume measurement with the BVA-100 blood volume analyzer showed statistically significantly reduced 30-day readmission and 30-day and one-year mortality rates. The study, published in the Journal of the American College of Cardiology - Heart Failure,1 compared the experimental group to propensity-matched controls.

Treatment guided by the BVA-100 blood volume analyzer resulted in a statistically significant decrease in rehospitalization (12.2 percent vs. 27.7 percent, p<0.001), 30-day mortality (2 percent vs. 11.1 percent, p<0.001) and 365-day mortality (4.9 percent vs. 35.5. percent, p<0.001), compared to a propensity score control. Further, an analysis of 30-day readmission by diagnosis showed fewer heart failure readmissions (6.1 percent vs. 20.2 percent, p<0.001) and fewer cardiac non-heart failure admissions (1.6 percent vs. 3.9 percent, p<0.001).

"The results of this outcome study demonstrate without question that accurate blood volume measurement substantially improves the physician’s ability to prescribe decongestion therapy that will result in significantly better outcomes in acute heart failure, particularly with regard to rehospitalization and mortality,” said John E. Strobeck, M.D., Ph.D., director, Heart-Lung Consultants Inc., Hawthorne, N.J., and lead author of the study. “These results clearly show that BVA measurement has a one-to-one relationship in achieving meaningful improvements in clinical and resource-use outcomes in patients hospitalized for acute heart failure.”

Total blood volume, red blood cell volume and plasma volume were measured using Daxor’s BVA-100, an I-131 labeled albumin indicator dilution technique that is unique to the BVA-100. Patients were assigned a decongestion and treatment strategy based on the BVA-100 measurement. Propensity score control matching was derived from CMS data matching 10:1 for demographics, comorbidity and year of treatment.
