VIDEO: Cardiovascular events in rheumatoid arthritis have decreased over decades

 

Key clinical point: Recent improvements in the management of rheumatoid arthritis may have had a positive impact on cardiovascular comorbidity.

Major finding: Risk ratios for myocardial infarction, heart failure, and CV mortality were lower between the period of 2000-2016 than for the period up to 2000.

Data source: Meta-analysis of 28 studies published up to March 2016 that provided data on CV event rates in RA patients and the general population.

Disclosures: Dr. Gaujoux-Viala had no relevant conflicts of interest to disclose.

– Recent improvements in the management of rheumatoid arthritis may have had a positive impact on common cardiovascular comorbidities, according to the results of a systematic review and meta-analysis.

Risk ratios (RR) for several CV events in rheumatoid arthritis (RA) patients were found to be lower for data published after 2000 and up to March 2016 when compared with data published up until 2000. Indeed, comparing these two time periods, French researchers found that the RR for myocardial infarction (MI) were a respective 1.32 and 1.18, for heart failure a respective 1.25 and 1.17, and for CV mortality a respective 1.21 and 1.07.

“Systemic inflammation is the cornerstone of both rheumatoid arthritis and atherosclerosis,” Cécile Gaujoux-Viala, MD, PhD, professor of rheumatology at Montpellier University, Nîmes, France, and chief of the rheumatology service at Nîmes University Hospital, said during a press briefing at the European Congress of Rheumatology.

“Over the past 15 years, new treatment strategies such as ‘tight control,’ ‘treat-to-target,’ methotrexate optimization, and use of biologic DMARDs [disease-modifying antirheumatic drugs] have led to better control of this inflammation,” Dr. Gaujoux-Viala added.

The aim of the meta-analysis was to look at the overall risk for CV events in RA patients versus the general population, she said, as well as to see if there had been any temporal shift by analyzing data obtained within two time periods – before 2000 and after 2000.

A systematic literature review was performed using the PubMed and Cochrane Library databases to search for observational studies that provided data about the occurrence of CV events in RA patients and controls. Of 5,714 papers that included reports of stroke, MI, heart failure, or CV death, 28 had the necessary data that could be used for the meta-analysis. Overall, the 28 studies included 227,871 RA patients, with a mean age of 55 years.

Results showed that RA patients had a 17% increased risk for stroke versus controls overall (P = .002), with a RR of 1.17. The RRs were 1.12 before 2000 and 1.23 after 2000, making stroke the only CV event that did not appear to show a downward trend.

Compared with the general population, RA patients had a 24% excess risk of MI, a 22% excess risk of heart failure, and a 18% excess risk of dying from a CV event (all P less than .00001).

These data provide “confirmation of an increased CV risk in RA patients compared to the general population,” said Dr. Gaujoux-Viala, who also discussed the study and its implications in a video interview.

Commenting on the study, Philip J. Mease, MD, of the University of Washington, Seattle, wondered where the studies used in the meta-analysis had been performed because of the potential impact that reduced access to CV medications or prevention strategies in certain countries could have on the results. However, the investigators did not determine where each of the studies used in the review took place.

Dr. Gaujoux-Viala had no relevant conflicts of interest to disclose.
