INTRODUCTION AND OBJECTIVES: Prior studies demonstrated that plasma osmolality may have a predictive value for in-hospital mortality in patients with heart failure and acute coronary syndrome. In addition, plasma glucose and blood urea nitrogen (BUN) levels, the components of plasma osmolality, have been shown to be an important contributor for in-hospital mortality in acute pulmonary embolism (APE) patients. Hence, the objective of the current study is to evaluate the effect of plasma osmolality upon admission with in-hospital mortality in patients with APE. METHODS:A total of 245 consecutive intermediate or high risk APE patients were enrolled into the study. The study population was divided into three tertile groups (T1, T2 and T3) based on the increased plasma osmolality. The in-hospital mortality was the primary end-point. RESULTS: After adjusting for all risk factors, in-hospital mortality was significantly higher in the T3 group compared to T1 and T2 groups (OR: 3.6, 95% CI: 1.3 to 18.8, P < .001). In addition, the incidence of asystolia, hypotension and cardiogenic shock were significantly higher in the T3 group. An area under the receiver operating characteristic curve value of plasma osmolality for the in-hospital mortality was 0.76 with sensitivity 67.2% and specificity 74.1% 95% CI: (0.66-0.87, P < .001). CONCLUSION: This is the first study to demonstrate that elevated levels of plasma osmolality may have a predictive value for in-hospital mortality in APE patients. Our findings are novel and deserve further studies whether the treatment of higher plasma osmolality may reduce the risk of in-hospital mortality in APE patients.
