The main outcome measures were all-cause death and HF hospitalisation at 1 year.<h4>Results</h4>Among 830 patients, a restrictive filling pattern was observed in 144 (17.3%) patients, who had higher prevalence of a history of atrial fibrillation and supranormal left ventricular ejection fraction (>65%), and higher brain natriuretic peptide level at discharge. The gene discussed is NPPB; the disease is hydrops fetalis.
