Implication
May support Specific Activity Scale in functional class research; leaves open whether it alters clinical decisions versus NYHA or CCS.
Structured PICO
Is the Specific Activity Scale more reproducible and valid than NYHA and CCS criteria for assessing cardiovascular functional class?
P
Population
Patients undergoing assessment of cardiac functional class
I
Intervention
Specific Activity Scale based on the metabolic costs of specific activities
C
Comparator
New York Heart Association (NYHA) criteria and Canadian Cardiovascular Society (CCS) criteria
O
Outcome
Reproducibility and validity (agreement with treadmill exercise performance)
The Specific Activity Scale offers improved validity and comparable reproducibility to existing functional classification systems like NYHA and CCS.
