Background and Aims: Recognition of heart failure with preserved ejection fraction (HFpEF) at an early stage in mass screening is desirable, but difficult to achieve. We examined whether the fibrosis (Fib)-4 index, a simple index of liver stiffness/fibrosis, could be used as a screening tool to select candidates requiring expert diagnostics. Methods: Individuals who participated in annual health checks between 2006 and 2007 in Arita-cho, Saga, Japan, with no history of cardiovascular disease and EF ≥ 50% were enrolled (total 710; 258 men; median age, 59 years). Results: Participants were divided into 5 groups according to HFpEF risk: 215 (30%), 100 (14%), 171 (24%), 163 (23%), and 61 (9%) with Heart Failure Association (HFA)-PEFF scores of 0, 1, 2, 3, and 4–6 points, respectively. The highest HFpEF risk group (HFA-PEFF score, 4–6 points) showed poor prognosis for the clinical events of all-cause mortality and hospitalization for HF (log-rank test, P = .002). The Fib-4 index was correlated with HFpEF risk stratification (rs = 0.526), and increment in the Fib-4 index was independently linked to high HFpEF risk by multiple logistic regression analysis (adjusted odds ratio, 1.311; 95% confidence interval, 1.078–1.595; P = .007). The Fib-4 index stratified clinical prognosis (log-rank test, P < .001) was an independent predictor of all-cause mortality and hospitalization for HF (hazard ratio, 1.305; 95% confidence interval, 1.139–1.495; P < .001). Conclusion: The Fib-4 index can be used to select appropriate candidates for a detailed examination of HFpEF in a subclinical population. |
