Abstract:
Objective: To preliminarily investigate the relationship between the baseline level of serum soluble ST2 (sST2) and 30-day MACE occurrence rate in patients with ST-elevation myocardial infarction (STEMI).
Methods: A total of 121 patients with confirmed diagnosis of STEMI in our hospital from 2015-05-01 to 2015-07-30 were consecutively enrolled. According to baseline sST2 level, the patients were divided into 2 groups:Low sST2 group, the patients with sST2≤56.68 ng/ml, n=61 and High sST2 group, the patients with sST2>56.68 ng/ml, n=60. Clinical condition and 30-day MACE (defined as death and new onset of congestive heart failure) occurrence rate were compared between 2 groups.
Results: ① The systolic blood pressure (SBP), Killip class≥II grade, blood levels of cTNI, NT-proBNP, hs-CRP and LVEF were different between 2 groups, all P<0.05. ② Baseline sST2 level was positively related to heart rate (r=0.271, P=0.003), Hs-CRP (r=0.359, P=0.000), cTNI (r=0.324, P=0.000) and NT-proBNP (r=0.425, P=0.000);negatively related to SBP (r=-0.226, P=0.013) and LVEF (r=-0.406, P=0.000).③30-day MACE occurrence rate was different between 2 groups (8.2%vs 30%, P=0.002). ④ Multivariate Cox regression analysis presented that sST2>56.68 ng/ml was the risk factor for 30-day MACE occurrence (HR=1.152, 95%CI 1.078-1.231, P=0.000).
Conclusion: Increased baseline level of sST2 implied the higher incidence of death and new onset of congestive heart failure in STEMI patients.
