In 183 patients we found metabolic syndrome (MS) according to IDF criteria.<\/jats:p>\n<jats:p><jats:bold>Results:<\/jats:bold> We found prevalence of cardiovascular diseases (CVD) of 73.5% (hyper-tension 70.4%, CHF 47.4%, ishemic heart disease 37.5%, and cardiac arrhythmias 12.6%), with higher prevalence in patients with more severe disease. We found prevalence of type 2 diabetes of 21.1%, and 12.4% prevalence of bronchiectasis. In a subpopulation of the patients we found 48.1% prevalence of MS and the serum levels of CRP were significantly higher in patients with COPD and MS compared to those without the syndrome: 7.4 (3.14 \u2013 11. 54) mg\/ml vs 4.06 (2.64 \u2013 6.93) mg\/ml, p=0.006.<\/jats:p>\n<jats:p><jats:bold>Conclusion:<\/jats:bold> The present study suggests high prevalence of CVD comorbidities in COPD patients and association with the disease severity.
