Abstract

Aims: Soluble suppression of tumorigenicity 2 (sST2) was validated to independently predict prognosis for heart failure (HF) and ST-segment elevation myocardial infarction (STEMI). In this study, we aimed to evaluate the relation between sST2 and coronary artery stenosis, and no-reflow phenomenon and one-year prognosis in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).

Methods: This prospective study consecutively enrolled 205 patients who were diagnosed with NSTE-ACS and underwent percutaneous coronary intervention (PCI). sST2 was measured for all patients during admission. Patients were divided into two groups based on the optimal cutoff value: sST2 >34.2 ng/ml and sST2 ≤ 34.2 ng/ml groups.

Results: Patients in the sST2 >34.2 ng/ml group was associated with higher Gensini scores and multivessel disease. sST2 had weak predictive value for no-reflow phenomenon (area under the curve [AUC], 0.662; 95% confidence interval [CI], 0.53–0.79; P=0.015) with 66.7% sensitivity and 65.2% specificity, and it also had independent predictive value of no-reflow phenomenon after adjusting for confounding factors (odds ratio [OR], 3.802; 95% CI, 1.03–14.11; P=0.046). sST2 >34.2 ng/ml had a commendable predictive value for the one-year prognosis (AUC, 0.84; 95% CI, 0.75–0.93; P<0.001) with 72% sensitivity and 84% specificity , and it independently predicted one-year major cardiovascular and cerebrovascular events (MACCE) (hazard ratio [HR], 10.22;95% CI, 4.05–25.7; P<0.001).

Conclusion: The sST2 concentration on admission is correlated with the degree of coronary artery stenosis. sST2 can predict both no-reflow and MACCE in patients with NSTE-ACS after PCI and was an independent predictor of MACCE and no-reflow phenomenon.
