Insights
Elderly patients with rheumatoid arthritis (RA) undergoing percutaneous coronary intervention (PCI) face higher mortality risks. Young-onset RA patients showed better survival than elderly-onset RA patients after PCI.
Area of Science:
- Cardiology
- Rheumatology
- Geriatrics
Background:
- Rheumatoid arthritis (RA) is a significant risk factor for cardiovascular disease.
- Understanding the impact of RA on outcomes after percutaneous coronary intervention (PCI) in elderly populations is crucial.
Purpose of the Study:
- To evaluate and compare the clinical outcomes, specifically survival rates, of elderly patients with and without rheumatoid arthritis (RA) following percutaneous coronary intervention (PCI).
Main Methods:
- A retrospective analysis of 74,623 elderly patients (≥ 65 years) who underwent PCI for acute coronary syndrome between 2008-2019 using the Korean National Health Insurance Service claims database.
- Comparison of all-cause mortality between patients with RA (n=14,074) and without RA (n=60,549).
- Subgroup analysis of survival outcomes based on the onset age of RA (young-onset vs. elderly-onset).
Main Results:
- Elderly patients with RA had a significantly lower survival rate compared to those without RA over a 10-year follow-up (53.7% vs. 58.3%, p < 0.001).
- Within the RA subgroup, patients with young-onset RA demonstrated better survival outcomes than those with elderly-onset RA and patients without RA (73.7% vs. 48.1% vs. 58.3%, p < 0.001).
- Elderly RA patients undergoing PCI experienced an elevated mortality risk, particularly those with elderly-onset RA.
Conclusions:
- Elderly patients with rheumatoid arthritis undergoing PCI have an increased risk of mortality.
- The age of RA onset significantly influences survival outcomes in elderly patients post-PCI, with young-onset RA associated with better prognosis than elderly-onset RA.
Abstract:
Rheumatoid arthritis (RA) increases the risk of cardiovascular disease. This study aimed to evaluate the clinical outcomes of elderly patients with and without RA who underwent percutaneous coronary intervention (PCI). The Korean National Health Insurance Service claims database was used to extract data on 74,623 patients (14,074 with RA and 60,549 without RA) aged ≥ 65 years who were diagnosed with acute coronary syndrome and underwent PCI between 2008 and 2019. The primary outcome was survival of elderly patients with and without RA. The secondary outcome was survival in the RA subgroup. During a 10-year follow-up, the all-cause mortality survival rate was lower in patients with RA than that in patients without (53.7% vs. 58.3%, respectively, log-rank: p < 0.001). In the all-cause mortality RA subgroup, patients with elderly-onset RA had poor survival outcomes, whereas patients with young-onset RA had good survival outcomes compared with that in patients without RA (48.1% vs. 73.7% vs. 58.3%, respectively, log-rank: p < 0.001). Elderly patients with RA who underwent PCI had an increased mortality risk, particularly those with elderly rather than young-onset RA.
