Insights
Osteoarthritis (OA) is linked to a higher risk of cardiovascular disease (CVD), especially for older men and adult women. This includes increased risks for ischemic heart disease (IHD) and congestive heart failure (CHF).
Area of Science:
- Cardiology
- Rheumatology
- Epidemiology
Background:
- Osteoarthritis (OA) is a prevalent degenerative joint disease.
- Cardiovascular disease (CVD) remains a leading cause of morbidity and mortality.
- The relationship between OA and CVD risk requires further investigation.
Purpose of the Study:
- To investigate the association between osteoarthritis and the risk of developing cardiovascular disease.
- To determine if OA is an independent predictor of CVD events.
- To analyze CVD risk stratification based on age and sex in OA patients.
Main Methods:
- Utilized population-based administrative data from British Columbia, Canada (1991-2009).
- Analyzed a cohort of 12,745 OA cases and matched non-OA controls.
- Employed Cox proportional hazards and Poisson regression models for risk estimation, adjusting for covariates.
Main Results:
- Osteoarthritis was identified as an independent predictor of CVD.
- Adjusted relative risks (RRs) for CVD were elevated in older men (1.15), younger women (1.26), and older women (1.17).
- Significant increases in risk for ischemic heart disease (IHD) and congestive heart failure (CHF) were observed, particularly in specific age-sex strata. OA patients undergoing total joint replacement showed a 26% increased CVD risk.
Conclusions:
- This study suggests a significant association between osteoarthritis and an increased risk of cardiovascular disease.
- Older men and adult women with OA face a heightened risk, particularly for IHD and CHF.
- Further research is warranted to confirm these findings and explore underlying biological mechanisms.
Objective:
To determine the risk of cardiovascular disease (CVD) among osteoarthritis (OA) patients using population-based administrative data from British Columbia, Canada.
Methods:
The medical history of a random sample of 600,000 individuals from 1991-2009 was analyzed. A total of 12,745 OA cases and up to 3 non-OA individuals matched by age, sex, and year of diagnosis were followed for CVD events. Cox proportional hazards and Poisson regression models were used to estimate the relative risks (RRs) of CVD, myocardial infarction, ischemic heart disease (IHD), congestive heart failure (CHF), and stroke after adjusting for available sociodemographic and medical factors.
Results:
OA was an independent predictor of CVD. The adjusted RRs were 1.15 (95% confidence interval [95% CI] 1.04-1.27), 1.26 (95% CI 1.13-1.42), and 1.17 (95% CI 1.07-1.26) among older men, younger women, and older women, respectively. Analyses were stratified by age and sex due to statistically significant interactions between OA and age and sex. RRs among older men, younger women, and older women were 1.33 (95% CI 1.11-1.62), 1.66 (95% CI 1.37-2.01), and 1.45 (95% CI 1.22-1.72) for IHD, respectively, and 1.25 (95% CI 1.02-1.54), 1.29 (95% CI 1.00-1.68), and 1.20 (95% CI 1.03-1.39) for CHF, respectively. Compared to non-OA individuals, OA cases who underwent total joint replacements had a 26% increased risk of CVD.
Conclusion:
This prospective longitudinal study suggests that OA is associated with an increased risk of CVD. Older men and adult women with OA had a higher risk of CVD, particularly IHD and CHF. Further studies are needed to confirm these results and to elucidate the potential biologic mechanisms.
