[Analysis on inpatient pulmonary hypertension surveillance in Fuwai Cardiovascular Hospital from 1996 to 2005].

Objective: To investigate the inpatient pulmonary hypertension (PH) surveillance in a single center of cardiovascular hospital during last ten years.

Methods: In this retrospective analysis, data from patients with discharge diagnosis as PH from Jan. 1996 to Dec. 2005 were collected.

Results: A total of 7085 out of 106 640 patients (6.63%) were documented as PH during the survey period and 3.77% PH was idiopathic, 65.93% PH originated from congenital heart diseases, 22.61% from left heart diseases, 5.66% from thrombotic diseases, 0.89% from respiratory diseases, 0.61% from connective tissue diseases, 0.51% from pulmonary vasculitis and 0.03% from portal hypertensive diseases. Both total inpatient number and patients with PH increased year by year during the last 10 years in our hospital. The number of in-hospital patients with PH was significantly higher in 2004 - 2005 than that in 1996 - 2003 (P < 0.0001) and more PH was originated from cardiomyopathy and valvular heart diseases. Idiopathic pulmonary hypertension also tended to increase and PH due to congenital heart diseases was significantly reduced during 2004 - 2005.

Conclusion: The data from a single center of cardiovascular hospital shows a tendency for increased in-hospital prevalence of pulmonary hypertension during the last ten years.
