Conclusion
Syncope-associated pulmonary embolism is a medical emergency that can be associated with poor prognosis and rapid decompensation. With a 90-day mortality rate of 17.4%. [3] pulmonary embolism requires heightened clinical suspicion and immediate therapy to prevent fatal pulmonary and cardiac complications. While current guidelines indicate that systemic and catheter-directed thrombolysis are reserved for those with hemodynamic instability, those presenting with recurrent syncope may predict rapid decompensation and may also benefit from early thrombolytic therapy or mechanical thrombectomy if contraindications exist.
