TNFi Cut Risk for Recurrent Cardiovascular Events in AxSpA

TOPLINE:
Tumor necrosis factor (TNF) inhibitors are associated with a reduced risk for recurrent cardiovascular events in patients with radiographic axial spondyloarthritis (axSpA) and a history of cardiovascular events.
METHODOLOGY:
The researchers conducted a nationwide cohort study using data from the Korean National Claims Database, including 413 patients diagnosed with cardiovascular events following a radiographic axSpA diagnosis.
Of all patients, 75 received TNF inhibitors (mean age, 51.9 years; 92% men) and 338 did not receive TNF inhibitors (mean age, 60.7 years; 74.9% men).
Patients were followed from the date of the first cardiovascular event to the date of recurrence, the last date with claims data, or up to December 2021.
The study outcome was recurrent cardiovascular events that occurred within 28 days of the first incidence and included myocardial infarction and stroke.
The effect of TNF inhibitor exposure on the risk for recurrent cardiovascular events was assessed using an inverse probability weighted Cox regression analysis.
TAKEAWAY:
The incidence of recurrent cardiovascular events in patients with radiographic axSpA was 32 per 1000 person-years.
The incidence was 19 per 1000 person-years in the patients exposed to TNF inhibitors, whereas it was 36 per 1000 person-years in those not exposed to TNF inhibitors.
Exposure to TNF inhibitors was associated with a 67% lower risk for recurrent cardiovascular events than non-exposure (P = .038).
IN PRACTICE:
“Our data add to previous knowledge by providing more direct evidence that TNFi [tumor necrosis factor inhibitors] could reduce the risk of recurrent cardiovascular events,” the authors wrote.
SOURCE:
The study was led by Oh Chan Kwon, MD, PhD, and Hye Sun Lee, PhD, Yonsei University College of Medicine, Seoul, South Korea. It was published online on October 4, 2024, in Arthritis Research & Therapy.
LIMITATIONS:
The lack of data on certain cardiovascular risk factors such as obesity, smoking, and lifestyle may have led to residual confounding. The patient count in the TNF inhibitor exposure group was not adequate to analyze each TNF inhibitor medication separately. The study included only Korean patients, limiting the generalizability to other ethnic populations. The number of recurrent stroke events was relatively small, making it infeasible to analyze myocardial infarction and stroke separately.
DISCLOSURES:
The study was funded by Yuhan Corporation as part of its “2023 Investigator Initiated Translation Research Program.” The authors declared no conflicts of interest.
