Exercise echocardiography in rheumatoid arthritis: a case-control study.

Area of Science:

• Cardiology
• Rheumatology
• Diagnostic Imaging

Background:

• Rheumatoid arthritis (RA) is a systemic autoimmune disease.
• RA is independently associated with a significantly elevated risk of cardiovascular disease.
• Early detection of cardiovascular complications in RA is crucial.

Purpose of the Study:

• To evaluate the utility of exercise echocardiography (EE) in assessing cardiovascular risk in rheumatoid arthritis (RA) patients.
• To determine the association between RA and myocardial ischemia.
• To investigate the impact of RA duration on ischemia risk and subsequent mortality.

Main Methods:

• Retrospective analysis of 159 RA patients who underwent EE.
• Matching RA patients with 454 controls based on age, gender, and cardiovascular risk factors.
• Follow-up duration averaged 6.7 years.

Main Results:

• RA patients had a 2.32-fold increased likelihood of positive ischemia results on EE.
• Rest and exercise wall motion score indexes were significantly higher in the RA group.
• Myocardial ischemia risk on EE increased by 1.06-fold per year of RA duration.
• Five-year all-cause mortality was 14.9% in RA patients with ischemia versus 4.3% without.

Conclusions:

• Exercise echocardiography is a valuable tool for identifying myocardial ischemia in RA patients.
• RA is strongly associated with a 2-fold increased risk of myocardial ischemia.
• Increased RA duration correlates with higher ischemia risk and mortality in RA patients.
