Objectives  To analyze the risk factors for cardiovascular disease (CVD) in patients with chronic obstructive pulmonary disease (COPD) of different severities. Methods  The study included 50 patients with mild-to-moderate COPD and 50 with severe-to-very severe COPD admitted between January 2014 and January 2016. Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS) score was determined in each subject. Results  There were more prevalences of smoking, depression and dyslipidemia in the patients with mild-to-moderate COPD than those with severe-to-very severe COPD (all P<0.001). The prevalences of high blood pressure, diabetes mellitus, alcoholism, and chronic heart failure were not different significantly between the two groups. The Charlson comorbidity index and HADS scores were not different between the two groups. Conclusions  Comorbidities are fairly common in COPD regardless of its severity. Certain risk factors for CVD, as smoking, dyslipidemia, and depression, appear to be more prevalent in patients with mild-to-moderate COPD.
