Patients and Study DesignThe study recruited 800 consecutive patients with HF who were hospitalized between 2018 and 2019 at the Gunma Prefectural Cardiovascular Center. After excluding patients who died during hospitalization, 743 patients who were discharged were enrolled.SRC was conducted by professional nutritionists (registered dietitians) to help HF patients reduce salt intake to <6 g/day after discharge. The counseling session was held once during HF hospitalization, and session lasted at least 30 min. Patients were followed up after discharge to record any deaths or HF rehospitalization events, which were analyzed as outcomes, together with the combined outcome of with or without SRC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
