ABSTRACT
Objective: To explore the relationship between plasma levels of soluble ST2 (sST2), galectin-3 (Gal-3) and clinical prognosis of ventricular septal myectomy in patients with obstructive hypertrophic cardiomyopathy (HOCM). Methods: A total of 200 consecutive HOCM patients received modified Morrow surgery in our hospital from 2011-03 to 2016-02 were studied. According to plasma levels of sST2, patients were divided into 3 groups: Low sST2 group (sST2<9.05 ng/ml), Middle sST2 group (sST2 9.05-16.74 ng/ml) and High sST2 group (sST2>16.74 ng/ml); based on plasma levels of Gal-3, patients were divided into another 3 groups: Low Gal-3 group (Gal-3<6.19 ng/ml), Middle group (Gal-3 6.19-8.22 ng/ml) and High Gal-3 group (Gal-3>8.22 ng/ml); in addition, Control group, n=42 volunteers without heart disease. Plasma levels of sST2 and Gal-3 were measured by ELISA, compared between Control group and HOCM group (n=42 patients with matched gender and age to Control group). The predictive value of sST2 and Gal-3 on major endpoint events including all cause death or cardiovascular hospitalization were assessed by Cox regression analysis.Results: Compared with Control group, plasma levels of sST2 and Gal-3 were increased in HOCM patients, P<0.01. The patients were followed-up for the average of 26 months, Kaplan-meier survival analysis showed that the incidences of composite endpoint event were similar at different levels of sST2 and Gal-3 (log-rank P=0.06 and P=0.68). Cox regression analysis indicated that either sST2 or Gal-3 could not independently predict the endpoint events, both P>0.05, while age was an independent risk factor for composite endpoint event occurrence (HR=1.06, 95% CI 1.02-1.11, P<0.01). Conclusion: Plasma levels of sST2 and Gal-3 were not related to clinical prognosis of ventricular septal myectomy in HOCM patients even they had increased sST2 and Gal-3; while advanced age was the independent predictor for endpoint event occurrence.
