Safety and Efficacy of Direct Blood Volume Measurement in the Treatment of Heart Failure (TEAM-HF)
2015年10月8日 更新者：Stuart Katz、NYU Langone Health
Treating to Euvolemia by Clinical Assessment and Measured Blood Volume in Heart Failure
Heart failure is a common cardiac condition affecting nearly 6 million Americans.
Silent blood volume overload is common in patients with heart failure and is associated with increased risk of death.
This study is designed to determine if adjustment of therapy based on direct measurement of blood volume will reduce risk of hospitalization and death when compared with therapy based on clinical assessment of blood volume in patients with chronic heart failure.
研究概览
详细说明
Multicenter prospective randomized trial to compare heart failure management strategies based on clinical assessment of volume status vs. direct measurement of blood volume with a radioisotope technique.
Subjects will be randomly assigned to a standard care strategy with guideline recommended treatment based on serial clinical assessment of blood volume or a measured blood volume strategy with guideline recommended treatment based on serial measured blood volume.
All subjects will undergo blood volume measurement procedures, but the testing results will only be returned to the physician in the group assigned to management according to measured blood volume status.
Subjects will be blinded to their study treatment assignment status.
