Peripheral artery disease (PAD) is highly prevalent and associated with poor outcomes. Depression is a risk factor for adverse outcomes in patients with coronary artery disease. Despite evidence showing that depression is common in patients with PAD, less is known about its association with adverse prognostic outcomes. To address this, we conducted a systematic review and meta-analysis to summarize the association between depression and outcomes in patients with PAD. We performed a systematic search of eight databases to January 2022 including studies that reported a risk estimate for the association of depression or depressive symptoms with all-cause mortality or major adverse limb events (MALE) in patients with PAD and pooled results in a meta-analysis. Risk of bias was assessed using ROBINS-I. Of the 7048 articles screened, 5 observational studies with 119,123 patients were included. A total of 16.2 % had depression or depressive symptoms. Depression was associated with a statistically significant increased risk of all-cause mortality (HR 1.24, confidence interval 1.07–1.25, p = .005). The association between depression and MALE was not significant but trended toward a positive association. Due to lack of data, results were limited by a single study with a large sample size, overrepresentation of men, and lack of information of depression severity or treatment status. Depression or depressive symptoms are associated with a 24 % increased risk of all-cause mortality in patients with PAD. Future work should explore the mechanisms and directionality of this association and identify depression as an important comorbidity to address for patients with PAD.
