Heart failure & cardiomyopathies

Relationship of red blood cell mass profiles and anemia type to outcomes and cardiopulmonary exercise performance in chronic heart failure

Am Heart JPublished Prospective cohort study

Authors' conclusion

Dilutional pseudo-anemia demonstrated higher HF hospitalizations compared to true anemia, while true anemia had a trend towards worse peak VO2.

Study context

Population
Chronic stable heart failure (HF) patients undergoing blood volume analysis (63% HFrEF)58 (48%) anemic
Participants
120 patients
Exposure
Anemia types and red blood cell mass (RBCM) profiles by blood volume analysis
Outcome
HF hospitalization
Follow-up
6 months

Main finding
