However, its antifibrotic activity can be associated with serosal inflammation and fluid retention. We report a case of an adult patient who, after allogenic hematopoietic stem cell transplantation, developed a GvHD treated with imatinib at low dosage, followed by multiorgan failure. Clinical examination and cardiac ultrasound were unable to clearly recognize the low cardiac output state; laboratory analysis, filling pressure, and computed tomography examination clarified the correct diagnosis. Low cardiac output state, secondary to pericardial effusion, is a diagnostic challenge. However, the association of four elements can help in its early recognition: increase in lactate levels and central venous pressure, associated with a low central venous saturation and a low brain natriuretic peptide level. Pericardial effusion with cardiac tamponade is a difficult diagnosis even with ultrasound. Lactate levels, central venous pressure plus venous saturation, and brain natriuretic peptide could help in early detection %K Cardiac tamponade %K central venous pressure %K graft versus host disease %U https://journals.sagepub.com/doi/full/10.1177/0300891618794890
