OBJECTIVES: The aim of the present study was to evaluate the relationship between exercise capacity and n/lymphocyte ratio (NLR) in patients enrolled in a cardiopulmonary rehabilitation program.
BACKGROUND: NLR has recently been used as a potential marker to determine inflammation in cardiac and non-cardiac diseases.
METHODS: In this retrospective study, an exercise test and six-minute walking test (6MWT) were carried out in 23 patients with coronary artery disease and 28 patients with pulmonary disease before cardiopulmonary rehabilitation program, and routine hemogram test results were evaluated.

RESULTS: The result of 6MWT test distance was 333.43 ± 86.58 m in the cardiac rehabilitation group and 348.46 ± 81.37 m in the pulmonary rehabilitation group. There was a negative correlation between 6MWT and NLR in the cardiac rehabilitation group (p < 0.05). As NLR increased, the MET value and duration of exercise decreased in the pulmonary rehabilitation group (p < 0.05).
CONCLUSION: NLR could be used as a predictor to evaluate the exercise capacity in patients to be enrolled in cardiopulmonary rehabilitation program (Tab. 3, Ref. 30)
