Amino acids predict prognosis in patients with acute dyspnea.

Background: To identify amino acids that can predict risk of 90-day mortality in patients with acute dyspnea.

Method: Plasma levels of nine amino acids were analyzed 663 adult patients admitted to the Emergency Department (ED) with acute dyspnea. Cox proportional hazards models were used to examine the relation between amino acid levels and the risk of 90-day mortality.

Inflammatory biomarkers predicting prognosis in patients with acute dyspnea.

Objective/purpose: The objective was to identify inflammatory biomarkers that predict risk of 90-day mortality in patients with acute dyspnea.

Method: We analyzed 25 inflammatory biomarkers, in plasma, in 407 adult patients admitted to the emergency department (ED) with acute dyspnea and related them to risk of 90-day mortality using Cox proportional hazard models adjusted for age, sex, oxygen saturation, respiratory rate, C-reactive protein, and Medical Emergency Triage and Treatment System-Adult score.

Results: Fifty patients (12%) died within 90 day from admission.
