Effect of estimated plasma volume status and left atrial diameter on prognosis of patients with acute heart failure
Abstract
ObjectiveAcute heart failure (AHF) is a frequent cardiovascular emergency presenting with high mortality as well as readmission rates. The aim was to investigate the predictive value of estimated plasma volume status (ePVs) and left atrial diameter (LAD) for the prognosis of patients with AHF.MethodsClinical profiles were collected from 259 cases of AHF patients at the Affiliated Hospital of Putian University between September 2019 and October 2021.ResultsSix patients lost follow-up, resulting in 253 patients enrolled. Cardiogenic death and heart failure readmission during follow-up were defined as major cardiovascular events (MACE) group, other patients were defined as Non-MACE group. Apart from age, no significant differences were found between the two groups in demographics and comorbidities. The comparison between the two groups was statistically significant in terms of ePVs, LAD, and N-terminal-pro B-type natriuretic peptide (Nt-pro-BNP). On binary logistic regression analysis, ePVs (OR = 2.061, 95% CI 1.322∼3.214, P = 0.001), LAD (OR = 1.054, 95% CI 1.012∼1.098, P = 0.011), and Nt-pro-bnp (OR = 1.006, 95% CI 1.003∼1.010, P = 0.036) as predicting factors for MACE. Kaplan-Meier analysis indicated that the risk for cardiogenic death increasing with ePVs (p < 0.05).ConclusionEstimated plasma volume status and LADs have some predictive value in assessing cardiogenic death and heart failure readmission in patients with AHF.
