Serum galectin-3 level increase correlates with poor prognosis in acute coronary syndrome
摘要
Levels of galectin-3 (GAL-3), a pro-inflammation biomarker, are closely associated with a diagnosis of acute coronary syndrome (ACS). However, the predictive ability of GAL-3 for long-term adverse prognosis in ACS has not been well-investigated. This prospective cohort study aimed to evaluate the predictive value of GAL-3 using classification and regression tree (CART) analysis.
ResultsA total of 134 patients with ACS at The Affiliated Hospital of Chengde Medical University were consecutively enrolled between January 2016 and May 2017. All included patients (102 [76.1%] male, median age, 58.18 years) completed follow-up (median, 6.5 years). The primary end-point was major adverse cardiovascular events (MACEs), including all-cause death, need for rehospitalization due to severe angina, and revascularization (re-percutaneous coronary intervention). CART results showed that GAL-3 had better prognostic ability than the other four cytokines and that the optimal GAL-3 cut-off value was 1.778 ng/mL. Kaplan–Meier analysis showed that the cumulative survival rate in the GAL-3 ≥ 1.778 ng/mL group was significantly lower than that in the GAL-3 < 1.778 ng/mL group (log-rank test, all p = 0.010). Cox regression analysis identified GAL-3 ≥ 1.778 ng/mL as an independent risk factor of long-term adverse prognosis in ACS.
ConclusionSerum level of the pro-inflammation cytokine GAL-3 ≥ 1.778 ng/mL was independently associated with a high risk of MACEs in patients with ACS.
