Background/Aims : In patients with chronic obstructive pulmonary disease (COPD), left ventricular (LV) systolic dysfunction and structural changes are rare, while right ventricular (RV) dysfunction and structural alteration and/or LV diastolic dysfunction are common. We evaluated the cardiac structure and function in patients with COPD using echocardiography.
Methods : Echocardiography examinations were performed in 69 patients with clinically stable COPD and without a history of heart disease; 22 control subjects with normal lung function were enrolled for comparison. Echocardiography parameters of the COPD patients were compared with those of the controls, and assessed according to the COPD stage classified using the Global initiative for chronic Obstructive Lung Disease (GOLD) criteria.
Results : Patients with COPD had significantly lower body weight (p=0.001) and higher pack-years of smoking than did the controls (p=0.002). The echocardiogram showed that LV end diastolic diameter (p<0.001), LV end systolic diameter (p=0.020), left atrial (LA) diameter (p=0.026), and LV mass in the COPD patients were significantly decreased compared to the controls (p=0.003). However, there were no differences between the COPD patients and controls in the parameters reflecting LV diastolic function and mean RV systolic pressure (RVSP). According to the COPD stage, body weight (p<0.001), body mass index (BMI) (p<0.001), and LV mass were significantly different (p=0.011). In patients with COPD, LV mass (r=0.432) (p<0.001) and BMI were significantly correlated with FEV1% predicted (r=0.600) (p<0.001).
Conclusions : Patients with COPD had lower LV mass and LA and LV diameters than did the controls, even though both groups had normal LV function. In particular, the LV mass appeared to correlate with the lung function in the patients with COPD. (Korean J Med 74:162-169, 2008)
