Short-term clinical outcome of normotensive patients with acute PE and high plasma lactate

Background Strategies for identifying normotensive patients with acute symptomatic PE at high risk of PE-related complications remain to be defined. Methods This prospective cohort study aimed to determine the role of plasma lactate levels in the risk assessment of normotensive patients with acute PE. Outcomes assessed over the 7 days after the diagnosis of PE included PE-related mortality and haemodynamic collapse, defined as need for cardiopulmonary resuscitation, systolic blood pressure
