摘要
Plasma extracellular vesicles (EV) are an emerging source of biomarkers for diagnosis and prognosis of cardiovascular disease (CVD). Risk stratification for common adverse events such as major adverse limb events (MALE) and major adverse cardiovascular events (MACE) by an EV blood sample could improve healthcare management by individualising drug therapy or improving informed decision making regarding revascularisations in patients with peripheral artery disease (PAD). As such, this study investigated the associations between plasma EV proteins and prospectively registered MALE and MACE in consecutive patients undergoing femoral endarterectomy.Using the Athero-Express biobank study, four EV proteins (Cystatin C, CD14, Serpin C1, and Serpin G1) were measured in the high density lipoprotein subfraction isolated from plasma of 317 PAD patients undergoing arterial revascularisation. Multivariable Cox proportional hazard regression was used to investigate the association between plasma EV protein levels and MACE and MALE in the three year post-operative period.Most patients were treated for claudication (Fontaine II, 52.8%), although rest pain (Fontaine III, 30.1%) and ischaemic wounds (Fontaine IV, 17.1%) were common in this cohort. Within three years 51 patients died, amongst whom 25 deaths were due to CVD, 39 patients experienced a MACE, and 125 patients experienced a MALE. Multivariable regression models, based on statistically proven covariables and literature, showed a significant association of Serpin G1 (HR 1.49; 95% CI 1.08 - 2.06; p = .016) and CD14 (HR 1.40; 1.03 - 1.90; p = .029) with MACE, and of Serpin G1 (HR 1.29; 1.07 - 1.57; p = .009) with MALE.Serpin G1 and CD14 plasma EV protein levels are associated with future MACE and MALE in patients with severe PAD.
