Abstract 2870: Peripheral Vascular Intervention in the Elderly: Is It Safe?
Background: The prevalence of peripheral arterial disease (PAD) increases with age. Advanced age has been linked to adverse outcomes associated with percutaneous coronary interventions. Advanced age may influence clinical outcomes of patients undergoing peripheral vascular intervention (PVI).
Objective: To evaluate the effect of age on procedure type, peri-procedural management, and in-hospital outcomes in patients undergoing PVI.
Methods: The study sample included 1545 patients (501 age ≥ 75, 1044 age < 75) undergoing PVI in a regional, contemporary, multicenter, multidisciplinary registry. Peri-procedural characteristics, and in-hospital outcomes were compared between older (age ≥ 75) and younger (age < 75) patients.
Results: See table⇓. Procedural success was > 97% in both groups. The post-procedure transfusion rate trended to be higher in the elderly, but overall adverse events did not differ. In older patients, predictors of post-procedure transfusion were female sex (OR 2.8, CI 1.1–6.9, p=0.02) and low pre-procedure hemoglobin (OR 3.8, CI 1.6–9.4, p=0.003).
Conclusions: PVIs were performed in elderly patients with very high procedural success and extremely low rates of peri-procedural complications. Elderly patients undergoing PVI were more likely female, had more renal, femoral popliteal, and below the knee arterial interventions. Post-procedure transfusion rates were significantly higher in elderly women, but this did not appear to affect in-hospital outcomes, and may be related to baseline hemoglobin differences.
