AB  - Objective To assess trends in incidence of cardiovascular disease (CVD) and mortality following incident CVD events in patients with rheumatoid arthritis (RA) onset in 1980- 2009 versus non-RA subjects. Methods We studied Olmsted County, Minnesota residents with incident RA (age ≥ 18 years, 1987 ACR criteria met in 1980-2009) and non-RA subjects from the same source population with similar age, sex and calendar year of index. All subjects were followed until death, migration, or 12/31/2016. Incident CVD events included myocardial infarction and stroke. Patients with CVD before RA incidence/index date were excluded. Cox models were used to compare incident CVD events by decade, adjusting for age, sex and CVD risk factors. Results The study included 905 patients with RA and 904 non-RA subjects. Cumulative incidence of any CVD event was lower in patients with incident RA in 2000s versus 1980s. Hazard Ratio [HR] for any incident CVD 2000s versus 1980s: 0.53; 95% confidence interval (CI): 0.31-0.93. The strength of association attenuated after adjustment for anti-rheumatic medication use: HR 0.64, 95%CI 0.34-1.22. Patients with RA in 2000s had no excess in CVD over non-RA subjects (HR: 0.71, 95%CI:0.42-1.19). Risk of death after a CVD event was somewhat lower in patients with RA after 1980s: HR: 0.54, 95%CI:0.33-0.90 in 1990s and HR: 0.68, 95%CI:0.33-1.41 in 2000s versus 1980s. Conclusion Incidence of major CVD events in RA has declined in recent decades. The gap in CVD occurrence between RA patients and the general population is closing. Mortality after CVD events in RA may be improving.
