Why the study?
Does the pulse-contour method accurately determine stroke volume compared to indicator-dilution methods in patients with ischemic heart disease or mitral valve disease?
Population
42 patients (21 with ischemic heart disease and 21 with mitral valve disease)

Pulse-contour estimates show moderate agreement with dilution methods in ischemic or mitral disease; leaves open precision for serial monitoring.
Does the pulse-contour method accurately determine stroke volume compared to indicator-dilution methods in patients with ischemic heart disease or mitral valve disease?
The pulse-contour method correlates well with indicator-dilution for stroke volume but has a 20% coefficient of variation, making it useful for rapid monitoring but not for detecting small changes.
