The value of growth differentiation factor 15 in early diagnosis of acute chest pain / 中华急诊医学杂志

ABSTRACT

Objective:To explore the value of growth differentiation factor 15 (GDF15) in the early diagnosis of acute chest pain.Methods:A total of 96 patients with acute chest pain admitted to the Emergency Department of Hainan Hospital of PLA General Hospital from January to November 2020 were retrospectively collected. The sex, age, troponin T, creatine kinase, creatine kinase isoenzyme, GDF15 and B-type natriuretic peptide of patients within 30 min after admission were recorded, and the differences of each index in different groups were compared. ROC curve was drawn to evaluate the diagnostic value of GDF15 and TNT/BNP in acute coronary syndrome (ACS). The Gensini score, left ventricular ejection fraction, length of stay in hospital and the number of stents were calculated, and the correlation between these indexes and GDF15 concentration was evaluated.Results:The general trend of acute chest pain was more male than female (72.92% vs. 27.08%) , the oldest group was the UA group (64.67 ± 13.87) years old , the youngest group was cardiac arrest group (47.29 ± 9.99) years old . There were higher rates of hypertension in the STEMI group, NSTEMI group and UA group, and none of the groups showed significant advantage in diabetes. The GDF15 concentration was higher in ACS related chest pain group [(2.360 ± 1.710) ng/mL vs. (1.380 ± 1.040) ng/mL, P<0.01]. The area under the Receiver Operating Characteristic Curve (AUC) of GDF15 combined with TNT was up to 0.863. GDF15 concentration was negatively correlated with ejection fraction, positively correlated with Gensini score, positively correlated with the number of stents implanted, and positively correlated with the length of hospital stay. Conclusions:GDF15 is valuable in the diagnosis and prognosis of acute chest pain. The combination of GDF15 and TNT can improve the diagnostic rate of ACS.
