    Objective: Based on our previous reports, ipsilateral systolic toe pressure (STP) and toe-brachial index (TBI) have a strong association with midterm cardiovascular and overall mortality as well as with amputation-free survival in patients with symptomatic lower extremity peripheral artery disease (PAD). The effect of the often overlooked contralateral lower limb on patient outcome remains unknown. This study aimed to resolve the significance of contralateral STP (CL_STP) and contralateral TBI for long-term overall and cardiovascular mortality. Methods: This is a retrospective cohort study of 727 consecutive patients with symptomatic lower extremity PAD. All patients admitted to the Department of Vascular Surgery at Turku University Hospital for digital subtraction angiography between January 2009 and August 2011 and for whom STP measurements were available were recruited and observed for up to 7 years. Dates and causes of death were collected from the national cause of death registry of Statistics Finland. Results: In the study cohort, STP was Conclusions: Low STP and TBI of both contralateral and ipsilateral lower extremities are associated with high cardiovascular and overall mortality in symptomatic PAD patients. Bilaterally low STP and TBI are associated with a particularly poor prognosis.
