Trends in All-Cause & CVD Mortality in Patients With RA

In a 20-year follow-up matched case-cohort study, all-cause and cardiovascular disease (CVD) mortality were significantly increased in patients with rheumatoid arthritis (RA) from 1994-2003, but not in patients diagnosed after 2004. Patients with disease onset 1994-2008 and 10 matched comparators for each case were linked to the Norwegian Cause of Death Registry. Hazard ratios for all-cause and CVD mortality were calculated for 5, 10, 15, and 20 years of observation using stratified Cox regression models. Researchers found:

  • Patients diagnosed with RA from 1994-2003 had significantly increased mortality vs controls.
  • Mortality was not significantly increased in patients diagnosed with RA from 2004 - 2008.
  • The risk of mortality for those diagnosed with RA before 2004 was increased throughout the observation period.
