Platelet-to-lymphocyte ratio as a novel marker of in-hospital and long-term adverse outcomes among patients with acute pulmonary embolism: A single center large-scale study
We assess the prognostic role of PLR in acute pulmonary embolism. In-hospital adverse events occurred more frequently in the highest tertile of PLR. Long-term all-cause mortality occurred more frequently in the third PLR tertile. PLR is significantly correlated with RV/LV ratio, cTnI levels and CTPAOI. PLR is a predictor of in-hospital adverse events and long-term all-cause mortality.
