Rheumatoid arthritis (RA) patients face an increased risk of major adverse cardiovascular events (MACE) and mortality. Standard risk factors do not fully account for these risks in RA patients, prompting researchers to investigate alternative measures such as high-sensitivity cardiac troponin T (hs-cTnT) testing. A recent study conducted at Brigham and Women’s Hospital in Boston revealed significant associations between positive hs-cTnT test results and subsequent cardiovascular events in RA patients.
Research Findings
The study followed a group of RA patients for an average of 5 years, during which positive hs-cTnT test results were linked to a higher risk of MACE and all-cause mortality. Even after adjusting for conventional risk factors and C-reactive protein (CRP) levels, the association remained strong. The use of hs-cTnT testing provided additional insights into the cardiovascular risks faced by RA patients, beyond what traditional risk assessment tools can predict.
Identifying RA patients with an elevated cardiovascular risk remains a challenge for clinicians. The study suggests that regular hs-cTnT testing could be a valuable tool in assessing and monitoring cardiovascular risk in RA patients. The findings indicate that hs-cTnT is an independent risk factor for MACE and mortality in RA patients, highlighting the importance of incorporating this test into routine clinical practice.
The researchers analyzed data from the BRASS study, a longitudinal study of RA patients that began in 2003. Blood samples collected annually from participants were tested for hs-cTnT, allowing for a comprehensive assessment of cardiovascular risk over a 10-year period. The study included over 1,500 participants, with 331 individuals providing sufficient data for detailed analyses.
Among the study participants, positive hs-cTnT results were associated with a significantly higher risk of MACE and mortality. The elevated risk observed in the presence of detectable hs-cTnT levels suggests the potential utility of this test in identifying RA patients at increased cardiovascular risk. Further research is needed to explore the relationship between hs-cTnT levels and atherosclerotic plaque burden in asymptomatic RA patients.
The study highlights the importance of regular hs-cTnT testing in monitoring cardiovascular risk in RA patients. By incorporating this sensitive test into routine care, clinicians may be able to identify high-risk individuals who could benefit from early intervention strategies. Further investigation into the long-term effects of disease-modifying treatments on MACE risk in RA patients is warranted to improve outcomes in this at-risk population.
