Comparative Value of NYHA Functional Class and Quality-of-Life Questionnaire Scores in Assessing Heart Failure

Abstract

Cardiopulmonary exercise variables and plasma NT-proBNP are associated more with NYHA functional class and SAQ score than with MLHF score. When combined, SAQ score, NT-proBNP, and etiology of heart failure can satisfactorily predict peak oxygen uptake.
