BackgroundWe investigated the measurement of soluble ST2 (sST2) in stable heart failure (HF) with a normal ejection fraction (HFNEF) in hypertensive patients.Methods and ResultsEchocardiography and serum N-terminal pro–B-type natriuretic peptide (NT-proBNP) and sST2 concentrations were evaluated in 107 hypertensive patients (65 ± 12 years, 57 male) with ejection fraction (EF) >50%. Among them, 68 patients with stable HF in functional class II and III were the HFNEF group. We found that the area under the receiver operating characteristic curve (AUC) for sST2 was 0.80 (95% CI 0.70–0.89; P < .001), relatively better than that for NT-proBNP (AUC 0.70, 95% CI 0.58–0.79; P = .003) to detect HFNEF. However, the NT-proBNP concentration, rather than sST2, was higher in HFNEF patients with functional class III (562 ± 891 vs 185 ± 242 pg/mL in functional class II; P = .009), and correlated better with mitral E/e′ (annular early diastolic velocity) (r = 0.327; P = .008) than sST2 concentrations in HFNEF patients. Multivariate analysis showed that sST2 >13.5 ng/mL was independently associated with HFNEF in hypertensive patients (odds ratio 11.7, 95% CI = 2.9–47.4; P = .001).ConclusionssST2 measurement provides diagnostic aid of stable HFNEF for hypertensive patients. Addition of NT-proBNP to sST2 could give further information regarding HF functional class and diastolic abnormality.
