title: Interventional cardiovascular procedures among HIV-infected individuals on antiretroviral therapy 1995-2000.
abstract: OBJECTIVE
  To calculate the rate of interventional cardiac procedures (ICP) among HIV-infected individuals ever treated with antiretroviral therapy (ART) and to describe clinical and sociodemographic characteristics associated with ICP.
  
  
  METHODS
  Since 1992, ART in British Columbia (BC) has been centrally distributed by the BC Centre for Excellence in HIV/AIDS. The BC Cardiac Registry maintains information regarding all cardiac procedures performed in BC. The two databases were linked to determine the number of HIV-positive individuals on ART who underwent ICP. Age-adjusted analyses were conducted using direct standardization, and linear regression to test for trend over time. Logistic regression was used to identify patient and treatment characteristics independently associated with having an interventional cardiac procedure.
  
  
  RESULTS
  Of the 5082 individuals who have ever received ART, 63 (< 1%) were captured in the Cardiac Registry. There were 97 events: 70 (72%) since 1999. The age-adjusted event rate per 1000 HIV-positive individuals on ART increased significantly over time (P = 0.015) whereas that for the general BC population did not increase over time (P = 0.191). In multivariate analysis, age at baseline per 10 year increase [adjusted odds ratio (AOR) 2.5; 95% confidence interval (CI), 1.8-3.2), and months on ART (AOR 1.3; 95% CI, 1.1-1.4) remained significant.
  
  
  CONCLUSIONS
  The rate of ICP among HIV-positive individuals on ART appears to be increasing; in addition, the duration of time on ART is independently associated with ICP after adjustment for patient demographic characteristics.
