Impact of cardiovascular risk factors and cardiac diseases on mortality in patients with moderate to severe ARDS: A retrospective cohort study.

Background: Histor of coronary artery disease (CAD) and/or atrial fibrillation (AF) and/or valvular replacement (VR) are prevalent among patients admitted to intensive care units (ICUs). The impact of these conditions on outcomes in patients with acute respiratory distress syndrome (ARDS) remains insufficiently explored.

Methods: We performed a retrospective study on prospectively collected data from patients with ARDS and a PaO/FiO ratio ≤150 mmHg.
