AIMS: Rheumatologic disorders are characterised by inflammation and an increased risk of coronary artery disease (CAD). However, the association between rheumatologic disorders and long-term prognosis in CAD patients undergoing percutaneous coronary intervention (PCI) is unknown. Thus, we aimed to examine the association between rheumatologic disorders and long-term prognosis in CAD patients undergoing PCI.
METHODS AND RESULTS: A post-hoc analysis was performed in 4605 patients (age: 63.3 ± 11.0 years; male: 76.6%) with ST-segment elevation myocardial infarction (STEMI; n = 1396), non-STEMI ( n = 1541), and stable CAD ( n = 1668) from the all-comer stent trials, the BAsel Stent Kosten-Effektivitäts Trial-PROspective Validation Examination (BASKET-PROVE) I and II trials. We evaluated the association between rheumatologic disorders and 2-year major adverse cardiac events (MACEs; cardiac death, nonfatal myocardial infarction (MI), and target vessel revascularisation (TVR)) by Cox regression analysis. Patients with rheumatologic disorders ( n = 197) were older, more often female, had a higher prevalence of renal disease, multi-vessel coronary disease, and bifurcation lesions, and had longer total stent lengths. During the 2-year follow-up, the MACE rate was 8.6% in the total cohort. After adjustment for potential confounders, rheumatologic disorders were associated with MACEs in the total cohort (adjusted hazard ratio: 1.55; 95% confidence interval (CI): 1.04-2.31) driven by the STEMI subgroup (adjusted hazard ratio: 2.38; 95% CI: 1.26-4.51). In all patients, rheumatologic disorders were associated with all-cause death (adjusted hazard ratio: 2.05; 95% CI: 1.14-3.70), cardiac death (adjusted hazard ratio: 2.63; 95% CI: 1.27-5.43), and non-fatal MI (adjusted hazard ratio: 2.64; 95% CI: 1.36-5.13), but not with TVR (adjusted hazard ratio: 0.81; 95% CI: 0.41-1.58).
CONCLUSIONS: The presence of rheumatologic disorders appears to be independently associated with worse outcome in CAD patients undergoing PCI. This calls for further studies and focus on this high-risk group of patients following PCI.
