Continuous Central Haemodynamic Measurements During the Six-Minute Walk Test and Daily Life in Patients with Chronic Heart Failure
Why the study?
Do haemodynamic responses differ between the 6-minute walk test and daily living activities in patients with chronic heart failure?
Population
18 patients with chronic heart failure
Comparison
Continuous haemodynamic monitoring via… vs Haemodynamic monitoring during the 6-minute walk…
Design
Cohort
Follow-up
14-day period surrounding each 6MWT

Implication
Daily activities elicit wider HR and pressure ranges than 6MWT in HF; leaves open whether continuous monitoring refines risk assessment.
Structured PICO
Do haemodynamic responses differ between the 6-minute walk test and daily living activities in patients with chronic heart failure?
P
Population
18 patients with chronic heart failure
I
Intervention
Continuous haemodynamic monitoring via implantable monitor during daily life (14-day period)
C
Comparator
Haemodynamic monitoring during the 6-minute walk test (6MWT)
O
Outcome
Haemodynamic responses (heart rate, estimated pulmonary artery diastolic pressure, and right ventricular pressure parameters)surrogate
Haemodynamic ranges during daily life exceed those observed during the 6-minute walk test in heart failure patients, suggesting daily monitoring may capture a broader physiological profile.
