Blood Volume and Hemodynamic Analysis in Patients With Chronic Heart Failure
Study type: Interventional What is this?
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
The primary hypothesis is that patients with HFREF (heart failure with reduced ejection fraction) will demonstrate a markedly expanded intravascular volume which will correlate with elevated right heart hemodynamics and increased venous capacitance parameters, whereas patients with HFPEF(heart failure with preserved ejection fraction) will demonstrate euvolemia to mild volume expansion and a lack of correlation with hemodynamic and venous compliance parameters.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
