title: [Classification and composition change of hospitalized patients with pulmonary hypertension in Xiangya Hospital from 2009 to 2013].
abstract: OBJECTIVE
  To analyze the classification and composition change of hospitalized patients with pulmonary hypertension (PH) in our hospital during recent 5 years.
  
  
  METHODS
  This retrospective analysis was performed for hospitalized patients with PH between January 2009 and November 2013.
  
  
  RESULTS
  A total of 1 003 patients diagnosed with PH were included, the PH-to-total discharged patients ratio was 2.30%. Majority PH (682, 68.00%) was originated from congenital heart diseases (CHD-PH), 11.67% (117) from connective tissue diseases, 11.26% (113) from valvular heart diseases, 4.99% (50) from idiopathic, 2.00% (20) from respiratory diseases. The CHD-PH decreased gradually (P = 0.041) while the VHD-PH increased gradually (P = 0.017) , especially in 2013. The percentage of right cardiac catheterization examination in this PH cohort was 18.64% (187/1 003). Excluding CHD-PAH and VHD-PH, the ratio of right cardiac catheterization examination in PH patients was 40.38% (84/208). Correct PH diagnosis by echocardiography was 74.00% (187/253) according to right cardiac catheterization examination. A total of 186 PH patients received pulmonary vascular-targeted medication, 84.90% patients were treated with mono-therapy.
  
  
  CONCLUSIONS
  The clinical data from Xiangya hospital in 2009-2013 shows a stable composition of hospitalized patients with PH, the rate of right cardiac catheterization in these patients is low and the rate of specific target treatment of PH is high (mostly mono-therapy) excluding CHD-PAH and VHD-PH patients.
