  • Clinical and laboratory data to explore mechanisms of RV dysfunction in each mechanistic category: ARDS, disordered coagulation, myocardial injury and ventilation.

  • ARDS, acute respiratory distress syndrome; BNP, brain natriuretic peptide; LV, left ventricle; NT-proBNP, N-terminal pro b-type natriuretic peptide; RV, right ventricle; TTE, transthoracic echocardiogram.
