Background: A prolonged heart rate-corrected QT interval (QTc) has been as sociated with peripheral artery disease (PAD) in the general population. Howe ver, no study to date has identified a link between prolonged QTc and the severity of PAD in patients with diabetes mellitus and foot ulcers (DFUs). This study aimed to investigat e this relationship. Methods: This multicenter study enrolled 281 patients with DFUs. The se verity of PAD was classified into no severe PAD group (without stenosis or occ lusion) and severe PAD group (with stenosis or occlusion) based on duplex ultrasonogra phy. The association of prolonged QTc with severe PAD was evaluated in a multivariable mixed-effect logistic regression model, with the hospital as a random effect. Directed acyclic graphs were used to drive the selection of variables to fit the regression m odel. Results: Patients with severe PAD had longer QTc than those without. Ba sed on the multivariable mixed-effect logistic regression model, a prolonged QTc was positively associated with severe PAD (odds ratio (OR) = 2.61; 95% CI: 1.07–6.35) and severe DFUs (Wagner grade score ≥ 3) (OR = 2.87; 95% CI: 1.42–5.81). Conclusions: A prolonged QTc was associated with severe PAD in patients wit h DFUs. Further research is required to ascertain whether the associati on is causal. |
