Abstract:
Background and Objects: chronic obstructive pulmonary disease (COPD) is one of the most common respiratory diseases. Its etiologic factor of the first magnitude is cigarette smoking. In its course, COPD has many complications in which there are cardiovascular ones showed by ECG abnormalities. To investigate ECG abnormalities at different stages of CODP and the correlation between cigarette smoking and severity of the disease, we analyzed cigarette consumption, ventilation function tests and ECG at 68 patients with COPD, Staging of COPD was based on American Thoracic Society's criteria 1995. Results: 52.3% of the patients had ECG abnormalities (ECG abnormality rates of the patients at stage 1,2 and 3 are 29.5%, 50% and 74.1% respectively). The frequent ECG abnormalities in COPD were right atrial hypertrophy (29.23%), right ventricular hypertrophy (7.69%) or both of them (15.38%). There was a negative and high correlation between cigarette consumption and% FEV1 (r=-0.8484), and cigarette consumption increased significantly from stage 1 to stage 3 of COPD. Conclusions: COPD at the more severe stage had the higher ECG abnormalities in COPD were right atrial hypertrophy, or right ventricular hypertrophy, or the both. The patients smoking more cigarettes were of more severe stage. Therefore, it is extremely important to advise the patients to stop smoking as soon as possible to prevent and manage COPD.
