ABSTRACT
OBJECTIVE:
The nature of peripheral arterial disease and postoperative outcomes are understudied in Asian patients. We aimed to determine if there are disparities in disease severity at the time of presentation and postoperative outcomes with regard to Asian race.METHODS:
We analyzed the Society for Vascular Surgery Vascular Quality Initiative Peripheral Vascular Intervention dataset from 2017 to 2021, which includes endovascular lower extremity interventions. Propensity scores were used to match White and Asian patients based on age, sex, comorbidities, ambulatory/functional status, and intervention level. Differences were examined with regard to Asian race across all patients in the United States, Canada, and Singapore, and separately in the United States and Canada only. The primary outcome was emergent intervention. We also examined differences in severity of disease and postoperative outcomes.RESULTS:
A total of 80,312 White and 1689 Asian patients underwent peripheral vascular intervention. After propensity score matching, we identified 1669 matched pairs of patients across all centers including Singapore and 1072 matched pairs in the United States and Canada only. Among the matched cohort consisting of all centers, Asian patients had a higher rate of emergent intervention to prevent limb loss (5.6% vs 1.7%, P < .001). The majority of Asian patients presented with chronic limb threatening ischemia at a higher rate than White patients within the cohort including Singapore (71% vs 66%, P = .005). Within both propensity-matched cohorts, the rate of in-hospital death was higher in Asian patients (all centers 3.1% vs 1.2%, P < .001; United States and Canada only 2.1% vs 0.8%, P = .010). Logistic regression demonstrated greater odds of emergent intervention in Asian patients from all centers including Singapore (odds ratio [OR], 3.3; 95% confidence interval [CI], 2.2-5.1, P < .001) but not in the United States and Canada only (OR, 1.4; 95% CI, 0.8-2.8, P = .261). In addition, Asian patients had greater odds of in-hospital death in both matched cohorts (all centers OR, 2.6; 95% CI, 1.5-4.4, P < .001; United States and Canada OR, 2.5; 95% CI, 1.1-5.8, P = .026). Asian race was associated with a greater risk of loss of primary patency at 18 months (all centers hazard ratio, 1.5; CI, 1.2-1.8, P = .001; United States and Canada only hazard ratio, 1.5; CI, 1.2-1.9, P = .002).CONCLUSIONS:
Asian patients are more likely to present with advanced peripheral arterial disease and undergo emergent intervention to prevent limb loss, in addition to having worse postoperative outcomes and long-term patency. These results highlight the need for improved screening and postoperative follow-up in this understudied population.Palabras clave
