Abstract

Background Soluble ST2 (sST2) is a marker of cardiac mechanical strain hypothesized to adversely impact short-term prognosis after myocardial infarction. We examined the association of sST2 with longer-term outcomes after myocardial infarction in a geographically defined community. Methods Olmsted County, Minnesota residents who experienced an incident (first-ever) myocardial infarction between November 1, 2002 and December 31, 2012 were prospectively enrolled; sST2 levels were measured. Patients were followed for heart failure and death. Results We studied 1401 patients with incident myocardial infarction (mean age 67 years; 61% men; 79% non-ST-elevation myocardial infarction). Median sST2 (ng/mL) was 48.7 (25th-75th percentile 32.5-103.3). Soluble ST2 was elevated in 51% of patients. Higher values of sST2 were associated with increased age, female sex, and comorbidities. During 5 years of follow-up, 388 persons died and 360 developed heart failure. After adjustment for age, sex, comorbidities, Killip class, and troponin T, the hazard ratios for death were 1.73 (95% confidence interval [CI], 1.22-2.45) and 3.57 (95% CI, 2.57-4.96) for sST2 tertiles 2 and 3, respectively (Ptrend <.001). For heart failure, the hazard ratios were 1.67 (95% CI, 1.18-2.37) and 2.88 (95% CI, 2.05-4.05), respectively (Ptrend <.001). Results were similar among 30-day survivors. Conclusions In the community, sST2 elevation is present in half of myocardial infarctions. Higher values of sST2 are associated with a large excess risk of death and heart failure independently of other prognostic indicators. Measurement of sST2 should be considered for risk stratification after myocardial infarction.
