Background: In chronic obstructive pulmonary disease (COPD), gender-specific differences in the level of symptoms and prevalence of comorbidities have been described. We studied whether the relationship between these characteristics was dependent on gender and whether they had different diagnostic value for cardiac comorbidities. Study Design and Methods: The analysis was based on 2046 patients (795 women; 38.8% ) of GOLD grades 1-4 from the COSYCONET COPD cohort. Assessments comprised the determination of clinical history and comorbidities, lung function, the COPD Assessment Test (CAT) and the modified Medical Research Council dyspnea scale (mMRC). Using multivariate regression analyses, potential gender differences in the relationship between symptoms, especially single CAT items, and the pattern of comorbidities and functional alterations were determined. In addition, we performed logistic regression analyses with age, BMI, smoking status, mMRC, CAT items, and z-scores of FEV1 and FEV1/FVC as predictors, to reveal the relationship to cardiac disease (defined as myocardial infarction, heart failure, or coronary artery disease) separately in men and women. Results: Most functional parameters and comorbidities, as well as CAT items 1 (cough), 2 (phlegm) and 5 (activities), showed significant (p<0.05) different values in men and women. Beyond this, the relationship between functional parameters and comorbidities versus symptoms showed gender-specific differences, especially for single CAT items. In men, logistic regression identified CAT item 8 (energy), mMRC, smoking status, BMI, age and spirometric lung function being related to cardiac disease. In women, only age was of predictive value for this disease. Conclusion: Gender-specific differences in COPD comprised not only differences in the level or prevalence of symptoms, comorbidities and functional alterations but also differences in their mutual relationships. This was reflected in different sets of predictors for cardiac disease. Our findings give hints how diagnostic information might be used differently in men and women.
