Abstract:Objective To analyze the clinical characteristics in the Uygur elderly patients with chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension (PH). Methods Two hundred and eighteen Uygur elderly patients with stable COPD admitted in the People’s Hospital of Yarkant County from February 2014 to May 2015 were enrolled in this study. According to the results of echocardiography, they were divided into 3 groups, that is, the patients complicated with no PH (n=96), suspected PH (n=68) and identified PH (n=54). Age, sex, body mass index, medical history, lung function, blood gas analysis, and serum levels of hemoglobin (HGB) and pro-brain natriuretic peptide (pro-BNP) were compared between those with identified PH and with no PH. Results The complicated PH group had significantly longer history of chronic cough and phlegm (P<0.01), obviously higher incidence of diabetes (P<0.05), and remarkably higher serum levels of HGB and pro-BNP (both P<0.01) when compared with those with no PH. They also had significantly higher values in forced expiratory volume in one second percentage of predicted value (FEV1%pred), diffusing capacity percent predicted (DLCO% pred), and arterial partial pressure of oxygen (PaO2; P<0.01), but not in other indices of lung function(P>0.05). Conclusion Attention should be paid to the above abnormal features and standard treatment given correspondingly, which might delay the progression and improve the prognosis in the Uygur elderly patients of COPD combined with PH.
