Natriuretic peptides (BNP and NT-proBNP) are recognized as gold-standard predictive markers in Heart Failure (HF). However, currently ST2 (member of the interleukin 1 receptor family) has emerged as marker of inflammation, fibrosis and cardiac stress. We evaluated ST2 and CRP as prognostic markers in 178 patients with chronic heart failure in comparison with other classical markers such as clinical established parameters but also biological markers: NT-proBNP, hs-cTnT alone or in combination. In multivariate analysis, subsequent addition of ST2 led to age, CRP and ST2 as the only remaining predictors of all-cause mortality (HR 1.03, HR 1.61 and HR 2.75, respectively) as well as of cardiovascular mortality (HR 1.00, HR 2.27 and HR 3.78, respectively). The combined increase of ST2 and CRP was significant for predicting worsened outcomes leading to identify a high risk subgroup that individual assessment of either marker. The same analysis was performed with ST2 in combination with Barcelona score. Overall, our findings extend previous data demonstrating that ST2 in combination with CRP as a valuable tool for identifying patients at risk of death.
We assessed the predictive ability of circulating biomarkers involved in collagen synthesis (procollagen type I N-terminal propeptide [PINP], and procollagen type III N-terminal propeptide [PIIINP], collagen degradation (c-terminal telopeptide of collagen type I [CTx] and mediators of cardiac fibrosis (Galectin-3 and soluble suppression of tumorigenicity 2 protein or sST2) as prognosis markers in 182 subjects with chronic heart failure (HF). In univariate analysis, all markers predicted mortality (except for PINP). A multivariate baseline model was fitted including variables potentially associated with mortality in HF patients. The baseline regression model included age, clinical data and biomarkers. We created four models from the baseline model augmented with the levels of hs-cTnT, CRP and NT-proBNP (model 1), CTx/PIIINP ratio, sST2 and Galectine-3 (model 2), NT-proBNP and sST2 (model 3) and NT-proBNP, CTx/PIIINP ratio and sST2 (model 4), to test whether these biomarkers have an incremental value for predicting mortality. After the addition of all biomarkers to the baseline model, age, CTx/PIIINP ratio and sST2 remained significant predictors. By contrast, Galectin-3 was not significantly associated with mortality. A multimarker strategy, demonstrated that the greatest prognostic improvement was attained with the combined addition of CTx/PIIINP ratio and sST2 highlighting the potential role of fibrosis pathways in risk stratification.
Aims Biomarkers are not recommended until now to guide the management of patients with heart failure (HF). Soluble suppression of tumorigenicity 2 (sST2) appears as a promising biomarker. The current study considered pre-discharged sST2 values as a guide for medical management in patients admitted for acute HF decompensation, in an attempt to reduce hospital readmission. Methods and results STADE-HF was a blinded prospective randomized controlled trial and included 123 patients admitted for acute HF. They were randomized into the usual treatment group (unknown sST2 level) or the interventional treatment group, for whom sST2 level was known and used on Day 4 of hospitalization to guide the treatment. The primary endpoint was the readmission rate for any cause at 1 month. It occurred in 10 patients (19%) in the usual group and 18 (32%) in the sST2 group without statistical difference (P = 0.11). Post hoc analysis in the whole group shows that the mean duration of hospitalization was lower in patients with low sST2 (<37 ng/mL) at admission vs. high sST2 (8.5 ± 9.5 vs. 14.8 ± 14.9 days, respectively, P = 0.003). In addition, a decrease in sST2 greater than 18% is significantly associated with a lower readmission rate. Conclusions Soluble suppression of tumorigenicity 2-guided therapy over a short period of time does not reduce readmissions. However, sST2 was clearly associated with duration of hospitalization, and the decrease in sST2 was associated with decreased rehospitalizations. Long-term outcome using sST2-guided therapy deserves further investigations.

Objectives: The aim of this study was to determine the 3-year outcomes of patients treated with Absorb bioresorbable vascular scaffold (BVS) implantation.Background: Randomized trials and observational registries performed in patients undergoing percutaneous coronary intervention have demonstrated higher 1-year and midterm rates of device thrombosis and adverse events with BVS compared to contemporary drug eluting stent. Data on long-term follow-up of patients treated with BVS are scarce.Methods: All patients treated with BVS were included in a large nationwide prospective multicenter registry (FRANCE ABSORB). The primary endpoint was a composite of cardiovascular death, myocardial infarction, and target lesion revascularization at 3 years. Secondary endpoints were 3-year scaffold thrombosis and target vessel revascularization (TVR).
