Value of Cardiac Biomarkers for Predicting Hypotension in Non-high-risk Patients with Acute Pulmonary Embolism

ABSTRACT

PURPOSE: Recent and numerous studies have indicated that cardiac biomarker elevation during acute pulmonary embolism (PE) predicts in-hospital death. However, the role of cardiac biomarkers for predicting the occurrence of hypotension is unknown. The aim of the present study was to evaluate whether increased levels of cardiac biomarkers can predict the occurrence of hypotension (sytolic blood pressure (SBP) 0.05 ng/mL) upon admission were an independent predictor for developing hypotension within 24 hours in patients with stable acute PE at the time of ED admission (odds ratio 11.0, 95% confidence interval (CI) 2.8-43.8, p=0.00). CONCLUSION: In stable patients with acute PE, an elevated TnI can predict the in-hospital development of hypotension within 24 hours. This finding is valuable for selecting patients who might benefit from intensive clinical surveillance and escalated treatment.
