Data ID 527
Factor breathless with lower 6-minute walk distance
Description The CHD-APAH patients were more breathless with lower 6-minute walk distance (360 m versus 558 m versus 622 m, P=0.00001).
Biomarker NA
Classification C3 (lifestycle factor - exercise habit)

Objective The CHD-APAH patients were more breathless with lower 6-minute walk distance
p Value 0.00001
Conclusion Raised biomarkers for inflammation were found in CHD-APAH. Significant abnormalities in airway physiology may contribute to the dyspnea but are not driven by inflammation as assessed by circulating and sputum cytokines. A relationship between increased serum endothelin-1 and airway dysfunction may relate to its bronchoconstrictive properties.
