Abstract
BACKGROUND: To investigate whether liver stiffness (LS) can predict adverse cardiac events in Chinese patients with heart failure (HF). METHODS: A total of 53 hospitalized patients with HF were enrolled, and LS and tricuspid annual plane systolic excursion (TAPSE) were determined with Fibroscan® and echocardiography before discharge. They were divided into two groups: high LS group (LS > 6.9 Kpa, n = 23) and low LS group (LS ≤ 6.9 Kpa, n = 30). Patients were followed up for 24 months at an interval of 3 months. The endpoint of follow-up was death or rehospitalization for HF. RESULTS: All patients were followed up for 24 months or until the endpoint. Patients in the high LS group had lower platelet count (P = 0.014), lower creatine clear rate (P = 0.014), higher level of B-type natriuretic peptide at discharge (P = 0.012), and lower TAPSE (P < 0.001) than those in the low LS group. During 24 months of follow-up, 3 (5.7%) deaths and 21 (39.6%) hospitalizations for HF were observed. Patients in the high LS group had a higher rate of death/rehospitalization than those in the low LS group (Hazard ratio 4.81; 95% confidence interval 1.69-13.7, P = 0.003) after adjustment for age, sex, platelet count, creatine clear rate, and B-type natriuretic peptide level. Moreover, TAPSE ≤ 16 could predict adverse cardiac events with an HR of 6.63 (95% confidence interval 1.69-13.7, P = 0.004) after adjustment for age, sex, platelet count, creatine clear rate, and B-type natriuretic peptide level. CONCLUSION: LS and TAPSE could be used to predict worse outcomes in patients with HF.
