Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

HF is an advanced or terminal stage of various heart diseases, with high rehospitalization and mortality rates. In HF patients, undernutrition is not uncommon and represents one of the most significant determinants of poor clinical outcomes. Therefore, nutritional management is of paramount importance for patients with HF.The basic method of nutritional management is to effectively identify the nutritional status of patients with heart failure, especially in elderly patients with heart failure who are not easy to find in the early stage. Limited data are available regarding the association between CONUT score and prognosis in elder patients with HFpEF, despite its easy availability in routine blood chemistry. Therefore, we aimed to evaluate the prognostic significance of CONUT score and to compare it with other well-established nutritional indices in HFpEF, a common HF phenotype in the elderly population with coronary artery disease.

This was a single-center retrospective cohort study which were approved by the Clinical Research Ethics Committee of our hospital (TRECKY2021-185). Written informed consent was obtained from all patients.

Participants were accorded with diagnostic criteria of CAD and HFpEF excluding rheumatic heart disease, congenital heart disease, acute myocardial infarction, hemodialysis or hemofiltration, tumour activity, urgent surgery, death during hospitalization, HF of unknown reasons, New York Heart Association(NYHA) class1and data deficiency. Demographic characteristics and medical parameters were collected from the electronic medical record system . All enrolled patients were followed-up in an outpatients setting. The primary endpoint of this study was readmission due to heart failure and all-cause mortality in the first year after hospitalization. To explore the prognostic significance of controlling nutritional status score in elderly with ejection fraction preserved heart failure and compare controlling nutritional status score with other objective nutritional indices.All analyses were performed using Statistical Product Service Solutions(SPSS) version 19.0 .
