ABSTRACT
Objective To investigate serum levels of soluble matrix lysin 2 (sST2) in patients with different stages of heart failure and its relationship with prognosis. Methods Data of 300 patients with heart failure of stages A, B, C and D were included in this study. Thirty-three cases of healthy elderly population for physical examination were used as control group. The general information, echocardiography and related biochemical tests containing sST2 and NT-proBNP were collected in the two groups. The survival periods of patients were evaluated according to the Seattle heart failure mode (SHFM). Patients were followed up for 1 year to record the occurrence of adverse events. Results The sST2 level was higher in heart failure group than that of control group. The sST2 level began to increase in stage B, and which increased with the development of cardiac function staging. The sST2 levels were significantly higher in stages B, C and D than those of stage A, and which were significantly higher in stage D than those of stages B and C (P<0.05). There were significantly higher incidence rates of adverse events, left ventricular end diastolic diameter (LVEDD) and left ventricular mass index (LVMI) in the patients with high sST2 level than those of patients with lower sST2 level (P<0.05). Values of sST2, NT-proBNP, LVEDD and LVMI were significantly higher, and values of LVEF and SHFM life expectancy were significantly lower, in patients with adverse events than those of patients without adverse events (P<0.05). There was a negative correlation between sST2 and LVEF, and positive correlation between sST2 with NT-proBNP, LVEDD and LVMI (P<0.05). The size under ROC curve, which was used to predict the cardiovascular endpoint events judged by sST2 was 0.665 (95%CI0.574-0.757, P<0.01), and the one by NT-proBNP was 0.790 (95% CI 0.731-0.848, P<0.01). The best cut-off value of predicting the clinical adverse events was 139.27μg/L by sST2 and 855.35μg/L by NT-proBNP. Conclusion The serum level of sST2 is early indicator of heart failure, which not only reflects the severity of ventricular remodeling but also is one of indicators to estimate the prognosis of heart failure in one year.
