ABSTRACT

Abstract Background: In clinical observation, patients with acute coronary syndrome complicated with peripheral artery disease have poor prognosis, so the relationship between the diseases and clinical characteristics need to be further explored. Objective: This study aims to investigate clinical characteristics and independent risk factors for in-hospital adverse events in acute coronary syndrome patients with a history of peripheral arterial disease (PAD). Methods: A total of 5,682 patients with acute coronary syndrome were included into this study. These patients were divided into two groups according to the presence or absence of a history of PAD: PAD group (n = 188), and non-PAD (control) group (n = 5,494). Then, the clinical characteristics and incidence of in-hospital adverse events were analyzed; p < 0.05 was considered statistically significant. Results: The age of PAD patients was higher than that in the control group (65.5 ± 10.3 years vs. 58.6 ± 11 years, p < 0.001), and the proportion of PAD patients with diabetes history and stroke history was higher than that in the control group (73 [39%] vs. 1472 [26.8%], p = 0.018; 36 [19.3%] vs. 396 [7.2%], p < 0.001). The multivariate logistic regression analysis between groups based on in-hospital adverse events revealed that a history of PAD (OR = 1.791, p = 0.01), a history of diabetes (OR = 1.223, p = 0.001), and age of > 65 years old (OR = 4.670, p < 0.001) were independent risk factors for in-hospital adverse events. Conclusion: A history of PAD, advanced age, and a history of diabetes are independent risk factors for in-hospital adverse events in patients with acute coronary syndrome.


Resumo Fundamento: Na observação clínica, os pacientes com síndrome coronariana aguda com doença arterial periférica têm prognóstico ruim, portanto, a relação entre as doenças e as características clínicas precisa ser mais explorada. Objetivos: Este estudo tem o objetivo de investigar características clínicas e fatores de risco independentes para eventos adversos hospitalares em pacientes com síndrome coronariana aguda e história de doença arterial periférica (DAP). Métodos: Foram incluídos no estudo 5682 pacientes com síndrome coronariana aguda. Os pacientes foram divididos em dois grupos de acordo com a presença ou ausência de DAP prévia: grupo DAP (n = 188) e grupo sem DAP (n = 5494, grupo controle). Em seguida, foram analisadas características clínicas e a incidência de eventos adversos hospitalares nesses grupos; um p < 0,05 foi considerado estatisticamente significativo. Resultados: A idade dos pacientes com DAP foi maior que a idade do grupo controle (65,5 ± 10,3 anos vs. 58,6 ± 11 anos, p < 0,001), e a proporção de pacientes com história de diabetes ou acidente vascular cerebral foi maior no grupo DAP que no grupo controle [73 (39%) vs. 1472 (26,8%), p = 0,018; 36 (19,3%) vs. 396 (7,2%), p < 0,001). A análise de regressão logística multivariada para eventos adversos hospitalares mostrou que história de DAP (OR = 1,791, p = 0,01), história de diabetes (OR = 1,223, p = 0,001), e idade >65 anos de idade (OR = 4,670, p < 0,001) foram fatores de risco independentes para eventos adversos hospitalares. Conclusão: DAP prévia, idade avançada, e história de diabetes são fatores de risco independentes para eventos adversos hospitalares em pacientes com síndrome coronariana aguda.
