Abstract
Abstract
Background
To identify disease-specific factors associated with cardiovascular events in patients with Takayasu arteritis (TAK).
Methods
Patients with TAK who fulfilled the American College of Rheumatology 1990 criteria for the classification of TAK and were followed up between 2006 and 2019 were included. Traditional cardiovascular risk factors and TAK disease-specific factors at the index date and incident cardiovascular events during the follow-up were retrospectively assessed. To estimate the risk of cardiovascular events according to TAK disease-specific factors, Cox regression analysis with adjustment for traditional cardiovascular risk factors was performed.
Results
Of the total 207 patients with TAK, cardiovascular events occurred in 41 (19.8%) patients. Compared with patients who did not develop cardiovascular events, patients who developed cardiovascular events were older (38.5 ± 13.4 years vs. 43.6 ± 11.8 years, p = 0.028), more commonly had diabetes mellitus (6.6% vs. 19.5%, p = 0.029), had lower high-density lipoprotein cholesterol (57.3 ± 17.1 mg/dl vs. 51.2 ± 15.7 mg/dl, p = 0.040), more commonly had type V vascular involvement (33.1% vs. 63.4%, p 0.001), and less commonly received methotrexate (65.1% vs. 43.9%, p = 0.013). In Cox regression analysis, type V vascular involvement was significantly associated with increased risk of cardiovascular events (adjusted HR 2.852, 95% CI 1.474–5.518, p = 0.002), whereas the use of methotrexate was associated with reduced risk of cardiovascular events (adjusted HR 0.515, 95% CI 0.268–0.993, p = 0.047).
Conclusion
Type V vascular involvement was associated with increased risk of cardiovascular events, while the use of methotrexate was associated with reduced risk of cardiovascular events, in patients with TAK.
