de Araujo GN, Beltrame R, Machado GP, et al. - Researchers sought to assess the correlation between left ventricular end-diastolic pressure (LVEDP) and bedside lung ultrasound (LUS) as well as to compare prognostic worth of these in patients receiving primary percutaneous coronary intervention, in this prospective cohort study. Participants were ST-segment–elevation myocardial infarction patients managed in a tertiary care hospital in Brazil. Findings demonstrated a weak correlation between LVEDP and LUS in this patient population. In acute heart failure, pulmonary congestion was recognized as a complex pathophysiological process and goes beyond fluid overload and hemodynamics. Multivariable analysis revealed a significant link of LUS, unlike LVEDP, with in-hospital major adverse cardiovascular events, new cardiogenic shock, and in-hospital mortality.
