Abstract

PURPOSE: . This study was designed to evaluate the role of bio-ADM in congestion assessment and risk stratification in acute dyspnea.

METHODS: . This is a sub-analysis of Lithuanian Echocardiography Study of Dyspnea in Acute Settings. Congestion was assessed by means of clinical (peripheral oedema, rales) and sonographic (estimated right atrial pressure [eRAP]) parameters. Ninety-day mortality was chosen for outcome analysis.

RESULTS: . 1188 patients were included. Bio-ADM concentration was higher in patients with peripheral oedema at admission (48.2 [28.2-92.6] vs 35.4 [20.9-59.2] ng/L, p<0.001). There was a stepwise increase in bio-ADM concentration with increasing prevalence of rales: 29.8 [18.8-51.1], 38.5 [27.5-67.1], and 51.1 [33.1-103.2] ng/L in patients with no rales, rales covering < ½, and ≥ ½ of the pulmonary area, respectively (p<0.001). Bio-ADM concentration demonstrated gradual elevation in patients with normal, moderately, and severely increased eRAP: 25.1 [17.6-42.4] ng/L, 36.1 [23.1-50.2] and 47.1 [30.7-86.7] ng/L, respectively (p<0.05). Patients with bio-ADM concentration > 35.5 ng/L were at more than two-fold increased risk of dying (p<0.001). Survival in those with high bio-ADM was significantly modified by neurohormonal blockade at admission (p<0.05), especially if NT-proBNP levels were lower than the median (p = 0.002 for interaction).

CONCLUSION: . Bio-ADM reflects the presence and the degree of pulmonary, peripheral, and intravascular volume overload and is strongly related to 90-day mortality in acute dyspnea. Patients with high bio-ADM levels demonstrated survival benefit from neurohormonal blockade.
