Aims The H 2 FPEF score is a convenient risk stratification tool for diagnosing heart failure with preserved ejection fraction (HFpEF). This study examined the value of the H 2 FPEF score for predicting all‐cause mortality and rehospitalization in HFpEF patients. Methods and results This was a retrospective cohort study of patients diagnosed with HFpEF by echocardiography at a single tertiary centre between 1 January 2015 and 30 April 2018. According to the H 2 FPEF score, the subjects were divided into low (0–1 points), intermediate (2–5 points), and high (6–9 points) score groups. The primary outcomes were all‐cause mortality and rehospitalization. A total of 476 patients (mean age: 70.5 ± 8.4 years, 60.7% female) were included. Of these, 47 (9.9%), 262 (55.0%), and 167 (35.1%) were classified into the low, intermediate, and high score groups, respectively. Over a mean follow‐up of 27.5 months, 63 patients (13.2%) died, and 311 patients (65.3%) were rehospitalized. The mortality rates were 3 (6.4%), 29 (11.1%), and 31 (18.6%), and the number of patients with rehospitalization was 28 (59.6%), 159 (60.7%), and 124 (74.3%) for the low, intermediate, and high score groups, respectively. Multivariate Cox regression identified H 2 FPEF score as an independent predictor of all‐cause mortality (hazard ratio [HR]: 1.46, 95% CI: 1.23–1.73, P < 0.0001) and rehospitalization (HR: 1.15, 95% CI: 1.08–1.22, P < 0.0001). Receiver operating characteristic (ROC) analysis demonstrated the H 2 FPEF score can effectively predict all‐cause mortality (AUC 0.67, 95% CI: 0.60–0.73, P < 0.0001) and rehospitalization (AUC 0.59, 95% CI: 0.54–0.65, P = 0.001) after adjusting for age and NYHA class. With a cut‐off value of 5.5, the sensitivity and specificity were 68.3% and 55.4% for all‐cause mortality and 50.5% and 66.7% for rehospitalization. Conclusions The H 2 FPEF score can be used to predict prognosis in HFpEF patients. Higher scores are associated with higher all‐cause mortality and rehospitalization.
