Correlation of the New York Heart Association classification and the cardiopulmonary exercise test: A systematic review

摘要

Aims: The New York Heart Association (NYHA) classification is frequently used in the management of heart failure but may be limited by patient and physician subjectivity. Cardiopulmonary exercise testing (CPET) provides a potentially more objective measurement of functional status. We aim to study the correlation between NYHA classification and peak oxygen consumption (pVO(2)) on Cardiopulmonary Exercise Testing (CPET) within and across published studies.
