Insights
Patients with seropositive rheumatoid arthritis (RA) have a significantly increased risk of developing congestive heart failure (CHF). This longitudinal study highlights the importance of monitoring cardiovascular health in RA patients.
Area of Science:
- Rheumatology
- Cardiology
- Epidemiology
Background:
- Rheumatoid arthritis (RA) is a chronic autoimmune disease.
- Cardiovascular complications, including congestive heart failure (CHF), are a concern in RA patients.
- The specific risk of CHF in seropositive RA populations requires further investigation.
Purpose of the Study:
- To determine the association between seropositive rheumatoid arthritis (RA) and the risk of congestive heart failure (CHF).
- To analyze the 12-year incidence of CHF in a nationwide Korean cohort with seropositive RA.
Main Methods:
- A longitudinal cohort study using National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) data (2002-2015).
- Defined seropositive RA by prescription of disease-modifying anti-rheumatic drugs (DMARDs) and ICD code M05.
- Compared 2765 seropositive RA patients with 13,825 controls using Kaplan-Meier and Cox proportional hazards regression.
Main Results:
- The adjusted hazard ratio for CHF in the seropositive RA group was 2.50 (95% CI: 1.45-4.30).
- Increased CHF incidence rates were observed in seropositive RA females across different age groups, particularly in those without hypertension, diabetes, or dyslipidemia.
- The risk of CHF was significantly elevated in the seropositive RA cohort.
Conclusions:
- Seropositive rheumatoid arthritis is associated with a substantially increased risk of congestive heart failure.
- These findings underscore the need for proactive cardiovascular risk assessment and management in patients with seropositive RA.
- Further research may explore the underlying mechanisms linking RA and CHF.
Abstract:
Objectives: The aim of this nationwide longitudinal cohort study is to determine the risk of congestive heart failure (CHF) associated with a seropositive rheumatoid arthritis (RA) population in Korea. Methods: In this study, National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) data from 2002 to 2003 were used. The cohort was followed up with for 12 years until December of 2015. Seropositive RA was defined as a patient prescribed with a disease-modifying anti-rheumatic drug (DMARD) among patients with the International Classification of Diseases code M05 (seropositive RA). Patients who were diagnosed before 2004 were excluded. The seropositive RA group consisted of 2765 patients, and a total of 13,825 patients were in the control group. The Kaplan-Meier method was used to calculate the 12-year CHF incidence rate for each group. A Cox proportional hazards regression analysis was used to estimate the hazard ratio of CHF. Results: The hazard ratio of CHF in the seropositive RA group was 2.41 (95% confidence interval (CI): 1.40-4.14) after adjusting for age and sex. The adjusted hazard ratio of CHF in the seropositive RA group was 2.50 (95% CI: 1.45-4.30) after adjusting for age, sex, income, and comorbidities. In females aged ≥65 and aged <65, the incidence rates in the non-hypertension, non-diabetes mellitus, and non-dyslipidemia subgroups were significantly higher in the seropositive RA group than in the control group. Conclusions: This nationwide longitudinal cohort study shows an increased risk of CHF in patients with seropositive RA.
