Management of a Patient with Pulmonary Embolism Taking Eliquis
A patient with pulmonary embolism (PE) who is already taking Eliquis (apixaban) does not need to go to the emergency room for a heparin drip unless they are experiencing hemodynamic instability (hypotension, shock) or significant clinical deterioration.
Risk Stratification and Initial Assessment
- Risk stratification is essential for determining appropriate management of PE patients, categorizing them as high-risk (hemodynamically unstable), intermediate-risk, or low-risk 1
- Patients with PE who present with hemodynamic instability (systolic BP <90 mmHg) are classified as high-risk and require immediate intervention 1
- For patients already on Eliquis without hemodynamic compromise, switching to heparin is generally unnecessary as NOACs (Novel Oral Anticoagulants) are recommended as first-line therapy for PE 1, 2
When Emergency Room Evaluation IS Necessary
Go to the ER immediately if experiencing:
- Hemodynamic instability (hypotension, systolic BP <90 mmHg) 1
- Significant respiratory distress or hypoxemia not responding to supplemental oxygen 3
- Signs of right ventricular dysfunction with clinical deterioration 1
- Severe, persistent chest pain unresponsive to analgesics 2
- New-onset syncope or altered mental status 2
When Switching from Eliquis to Heparin May Be Indicated
- FDA labeling specifically states: "Initiation of apixaban tablets are not recommended as an alternative to unfractionated heparin for the initial treatment of patients with PE who present with hemodynamic instability or who may receive thrombolysis or pulmonary embolectomy" 4
- For patients with high-risk PE (with hemodynamic instability), systemic thrombolytic therapy is recommended, which requires hospitalization and typically heparin administration 1
- Rescue thrombolytic therapy is recommended for patients who show hemodynamic deterioration while on anticoagulation treatment 1
Continued Management on Eliquis
For stable PE patients already taking Eliquis:
- Continue the prescribed Eliquis regimen without interruption 1
- NOACs like Eliquis are recommended over vitamin K antagonists for PE treatment in eligible patients 1
- Eliquis has been shown to be noninferior to conventional anticoagulation with a lower bleeding risk in PE patients without hemodynamic compromise 2, 5
- Regular follow-up is recommended to assess treatment response and monitor for complications 1
Common Pitfalls to Avoid
- Unnecessarily switching from an effective NOAC (Eliquis) to parenteral therapy when not clinically indicated 1, 5
- Failing to recognize signs of clinical deterioration that would warrant emergency evaluation 1, 3
- Overlooking the need for risk stratification in determining the appropriate treatment setting 1
- Not considering rescue thrombolytic therapy in patients with worsening clinical status despite anticoagulation 1
Conclusion for Clinical Practice
- For hemodynamically stable patients with PE already taking Eliquis appropriately, continuing the current regimen is recommended rather than switching to heparin 1, 2
- Only patients with high-risk PE (hemodynamic instability) or those showing clinical deterioration while on Eliquis should be considered for emergency room evaluation and potential switch to heparin with consideration of thrombolysis 1, 4
