BackgroundIn 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.ObjectiveThis 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).MethodsA 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.ResultsThe 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.ConclusionA 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.
