Introduction. Pulmonary hypertension is the most common complication of chronic obstructive pulmonary disease (COPD). Mortality rate will increase when COPD complication with pulmonary hypertension. Right heart catheterization (RHC) is the most common tool to measure mean pulmonary arterial pressure (mPAP) either in COPD patients with exacerbations treated in intensive care unit. Data of pulmonary hypertension in stable COPD group is still relatively rare. Alternatively to RHC, nowadays echocardiography is used to measure mean pulmonary arterial pressure in stable COPD group. Methods. A cross-sectional study was conducted on fifty-eight stable male COPD patients (mean age: 67,6) underwent spirometry. Mean pulmonary arterial pressure was measured using transthoracic echocardiography at short axis view in aortic level. Results. Mean value of forced expiratory volume in 1 second (FEV1)% was 26,6 % (SD 4,7) with median value of mean pulmonary arterial pressure was 37,61 mmHg (range 18,3-59). As many as 74% subjects were pulmonary hypertension; 24 % mild, 31 % moderate and 19% severe respectively. The correlation test showed a significant strong-negative correlation (r = -0,948, p <0,001). The best cut-off point of FEV1% prediction, which had a clinical value correlated with mPAP, was 55,3% with the sensitivity 93 %. Conclusions. Forced expiratory volume in one second (FEV1)% prediction has a significant correlation with mean pulmonary arterial pressure in stable COPD patients. The cut-off point FEV1% prediction 55,3% has a good capability to discriminate pulmonary hypertension in stable COPD patient.
