Prognostic value of biomarkers of ischaemia in patients with peripheral arterial disease following endovascular revascularisation.

Our aim was to evaluate the prognostic value of detectable high-sensitivity cardiac troponin I (hs-cTnI) and ischaemia-modified albumin (IMA) in predicting all-cause death or non-fatal ischaemic events in patients with PAD after endovascular revascularisation of the lower limbs. Patients who underwent successful endovascular revascularisation for chronic limb-threatening ischaemia (CLTI) or disabling intermittent claudication (IC) were prospectively included. Pre-procedural levels of hs-cTnI and IMA were measured, and patients were followed for one year for the occurrence of the composite outcome of all-cause death, non-fatal myocardial infarction, new-onset angina, non-fatal ischaemic stroke, transient ischaemic attack, or progression of PAD.
