AI-Summary

What this Trial Is About

In this study, we will assess the efficacy and safety of a reduced dose of thrombolytic therapy given in addition to low-molecular-weight heparin in patients with intermediate-high-risk acute pulmonary embolism. Half of participants will receive thrombolytic treatment, while the other half will receive a placebo.
