Males With Rheumatoid Arthritis Often Evidence Carotid Atheromas on Panoramic Imaging: A Risk Indicator of Future Cardiovascular Events

Purpose Males with rheumatoid arthritis (RA) are at an exceedingly high risk of adverse intraoperative ischemic events, given the role of systemic inflammation in the atherogenic process. We hypothesized that their panoramic images would demonstrate calcified carotid artery atheromas (CCAPs) significantly more often than those from a general population of similarly aged men. Patients and Methods We implemented a retrospective observational study. The sample was composed of male patients older than 55 years of age who had undergone panoramic imaging studies. The predictor variable was the diagnosis of RA confirmed by a positive rheumatoid factor (RF) titer, and the outcome variable was the prevalence rate of CCAPs. The other major study variable was the level of RF among the patients evidencing CCAPs. The prevalence of CCAPs among the patients with RA was then compared with that of a historical general population of similarly aged men. Descriptive and bivariate statistics were computed, and the P value was set at .05. Results Of the 100 men (mean age 69.89 ± 8.927 years) with RA, 29 (29%; mean age 72.10 ± 7.68 years) had atheromas (CCAP+). Of these 29 men, 25 (86%; mean age 71.88 ± 7.43 years) had a RF titer of ≥41 IU/mL, twice that of normal. A statistically significant ( P Conclusions The results of the present study suggest that CCAP, a risk indicator of future adverse cardiovascular events, is frequently seen on panoramic images of male patients with RA and that these individuals routinely manifest high titer levels of RF, a biologic marker of inflammation. Oral and maxillofacial surgeons planning surgery for male patients with RA must be uniquely vigilant for the presence of these lesions.
