Stromal Cell Derived Factor-1 and Long-term Prognosis in Acute Coronary Syndrome

To explore long-term prognostic value of SDF-1 in acute coronary syndrome (ACS). We included 254 patients with ACS. Plasma SDF-1 was measured and patients were classified into tertiles of SDF-1. Multivariate analysis showed third tertile of SDF-1 as an independent predictor of all-cause death (HR: 2.5; 95% CI: 1.2-5.2; p = 0.011) and the composite of major adverse cardiovascular and cerebrovascular events (HR: 1.8; 95% CI: 1.1-3.1; p = 0.031). SDF-1 added to a clinical model can improve all-cause death prediction (net reclassification improvement 0.362; 95% CI: 0.423-0.681; p = 0.027). SDF-1 is an independent predictor of all-cause mortality and major adverse cardiovascular and cerebrovascular events in long-term follow-up of patients with ACS and adds prognostic information beyond traditional cardiovascular risks factors.
