Avci A, Biricik S, Avci BS, et al. - Researchers investigated if the monocyte to HDL cholesterol ratio in patients diagnosed with pulmonary embolism could be used to effectively predicting intra-hospital mortality. They retrospectively studied a total of 269 patients (Mean age: 64.51 ± 12.4 years) diagnosed with pulmonary embolism in the emergency clinic. The group with mortality had significantly higher Pulmonary Embolism Severity Index (PESI), number of monocytes and MHR and had significantly lower HDL values compared with the group without mortality. Sensitivity was 89.3%, and specificity was 82.0% for MHR 19 cut off value. Findings emphasize the significance of using predictors for mortality estimation in patients diagnosed with acute pulmonary embolism for faster administration of treatment modalities. The hemogram parameters and biochemical results suggest the potential value of MHR as a strong predictor.
