The primary endpoint was a composite endpoint including death, circulatory assistance, urgent transplantation or rehospitalization for acute RHF within 90 days following inclusion.Among the 46 patients analysed (67% female, age 60±15 years), all received intravenous diuretics and 27 (57%) required inotropic and/or vasopressor support. At admission, the median values of RRI and RVSI were respectively 0.75 [IQR, 0.69-0.86] and 0.48 [IQR, 0.27-0.6]. RRI>0.75 was significantly associated with lower eGFR (p=0.023) and lower systemic mean arterial pressure (p=0.015). RVSI>0.48 was associated with lower eGFR (p=0.004), higher central venous pressure (p<0.001) and higher NT-proBNP (p=0.013). A primary endpoint event occurred in 12 patients (24%). In Kaplan–Meier analysis, the event rate was higher in patients with RRI>0.75 at admission (p=0.02) but not in patients with RVSI>0.48. At day-3, a decrease in both RRI and RVSI was associated with better outcomes (p=0.003 and p<0.0001, respectively). No event occurs in patients who improved both RRI and RVSI at Day 3.Arterial and venous renal doppler seem to be relevant tools for prognostic evaluation of acute decompensated precapillary PHFootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA1925.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
