OBJECTIVE
To investigate the risk profiles, treatment, and outcomes of patients with rheumatoid arthritis (RA) with myocardial infarction (MI) and matched MI patients without RA.
METHODS
We used a population-based cohort of Olmsted County, Minnesota, residents with MI from the period 1979-2009. We identified 77 patients who fulfilled the American College of Rheumatology 1987 criteria for RA and 154 MI patients without RA matched for age, sex, and calendar year. Data collection from medical records included RA and MI characteristics, antirheumatic and cardioprotective medications, reperfusion therapy, and outcomes (mortality, heart failure, and recurrent ischemia).
RESULTS
The mean age at MI was 72.4 years and 55% of patients were female in both cohorts. Cardiovascular risk factor profiles, MI characteristics, and treatment with reperfusion therapy or cardioprotective medications were similar in MI patients with and those without RA. Patients with RA experienced poorer longterm outcomes compared to patients without RA--for mortality: hazard ratio (HR) 1.47; 95% CI 1.04, 2.08; and for recurrent ischemia: HR 1.51; 95% CI 1.04, 2.18.
CONCLUSIONS
MI patients with RA received similar treatment with reperfusion therapy and cardioprotective medications and had similar short-term outcomes compared to patients without RA. Patients with RA had poorer longterm outcomes. Despite similar treatment, MI patients with RA had worse longterm outcomes than MI patients without RA.
