COPD in chronic heart failure: Less common than previously thought?

Item does not contain fulltextBACKGROUND: Using a fixed ratio of forced expiratory volume in 1 s to forced vital capacity (FEV1/FVC) LLN). In contrast to patients with LLN-COPD, potentially misclassified patients did not differ significantly from those without COPD regarding respiratory symptoms and risk factors for COPD. CONCLUSIONS: One fifth, rather than one third, of the patients with chronic HF had concomitant COPD using the LLN instead of the fixed ratio. LLN may identify clinically more important COPD than a fixed ratio of 0.7
