AB  - Background: Pulmonary Hypertension(PH) has been proposed a higher incidence in Interstitial Lung Diseases(ILDs).PH in different ILDs has different pathogenesis. PH in patients with ILDs is not well recognized and can occur in the absence of advanced pulmonary dysfunction or hypoxemia.Objective: To investigate the incidence of pulmonary hypertension in different types of interstitial lung diseases.Methods: Two hundred and five patients with ILD between 24 and 89 years old(mean age one hundred and four male, one hundred and one female) were evaluated, to discuss the incidence with different primary diseases, age and gender. ILD was diagnosed according to ATS/ERS classification standards in 2002, and according to ESC/ERS Guidelines in 2009, PH was diagnosed when SPAP of > 50mmHg was measured by UCG.Results: Two hundred and five ILDs in Beijing Chao-Yang Hospital, ranging from January 1st 2010 to June 8th 2011, 27 were diagnosed as PH, so the incidence of PH in ILD is 13.2%. There was no significant difference of the incidence of PH in ILD between males and females (p=0.901).There was a significant difference of the incidence of PH in ILD between age > 60ys and < 60ys (p=0.017).The incidence of PH has no statistically significant difference among different types of ILD (p=0.455).Conclusion: The total incidence of PH in ILDs is 13.2%, the patients with age ≥60y have higher incidence of PH. Whether PH develops in ILD seems to have no relation with the ILD types.Key words: Interstitial lung diseases, pulmonary hypertension, incidence.
