Overview
In most cases, anticoagulant therapy is the mainstay of treatment.
Treatment Protocol[1]

Heparin
Subcutaneous Low molecular weight heparin, fondapariux or or Intravenous heparin is indicated in hemodynamically stable patients.
Dosages
Following doses are recommended[2]:
- Low molecular weight heparin
- Enoxaparin : 1 mg/Kg body weight (twice daily).
- Tinzaparin : 175 U/Kg body weight (once daily).
- Factor Xa Inhibitors/Fondaparinux
- Patient weighing less than 50 Kg (110 lb) : 5 mg (once daily).
- Patient weighing 50 Kg (110 lb) to 110 Kg (220 lb): 7.5 mg (once daily).
- Patient weighing more than 100 Kg (220 lb) : 10 mg (once daily).
- Unfractionated heparin
- Loading Dose: 80 IU/Kg or 5000 IU
- Mantainace Dose: 18 IU/Kg/Hr to achieve a target aPTT 1.5 to 2.5 times the normal value.

Class I1. Anticoagulation with unfractionated heparin should be initiated without delay in patients with high-risk PE. (Level of Evidence: A) 2. Systemic hypotension should be corrected to prevent progression of RV failure and death due to PE. (Level of Evidence: C) 3. Vasopressive drugs are recommended for hypotensive patients with PE. (Level of Evidence: C) Class IIa4. Dobutamine and dopamine may be used in patients with PE, low cardiac output and normal blood pressure. (Level of Evidence: B) Class III5. Aggressive fluid challenge is not recommended. (Level of Evidence: B) Class I6. Oxygen should be administered in patients with hypoxaemia.(Level of Evidence: C) 7. Thrombolytic therapy should be used in patients with high-risk PE presenting with cardiogenic shock and/or persistent arterial hypotension.(Level of Evidence: A) 8. Surgical pulmonary embolectomy is a recommended therapeutic alternative in patients with high-risk PE in whom thrombolysis is absolutely contraindicated or has failed.(Level of Evidence: C) Class IIb9.Catheter embolectomy or fragmentation of proximal pulmonary arterial clots may be considered as an alternative to surgical treatment in high-risk patients when thrombolysis is absolutely contraindicated or has failed. (Level of Evidence: C) |

Class I1. Anticoagulation should be initiated without delay in patients with high or intermediate clinical probability of PE while diagnostic workup is still ongoing. (Level of Evidence: C) 2. Use of LMWH or fondaparinux is the recommended form of initial treatment for most patients with non-high-risk PE. (Level of Evidence: A) 3. In patients at high risk of bleeding and in those with severe renal dysfunction, unfractionated heparin with an aPTT target range of 1.5–2.5 times normal is a recommended form of initial treatment. (Level of Evidence: C) 4. Initial treatment with unfractionated heparin, LMWH or fondaparinux should be continued for at least 5 days and (Level of Evidence: A) may be replaced by vitamin K antagonists only after achieving target INR levels for at least 2 consecutive days (Level of Evidence: C) Class IIb5. Routine use of thrombolysis in non–high-risk PE patients is not recommended, but it may be considered in selected patients with intermediate-risk PE (Level of Evidence: B) Class III6. Thrombolytic therapy should be not used in patients with low-risk PE (Level of Evidence: B) |

ESC Guidelines Recommendations Long-term treatment (DO NOT EDIT)
| “ |
Class I1. For patients with PE secondary to a transient (reversible) risk factor, treatment with a VKA is recommended for 3 months.(Level of Evidence: A) 2. For patients with unprovoked PE, treatment with a VKA is recommended for at least 3 months. (Level of Evidence: A) 3. For patients with a second episode of unprovoked PE, long-term treatment is recommended. (Level of Evidence: A) 4. In patients who receive long-term anticoagulant treatment, the risk/benefit ratio of continuing such treatment should be reassessed at regular intervals. (Level of Evidence: C) 5. In patients with PE, the dose of VKA should be adjusted to maintain a target INR of 2.5 (range 2.0–3.0) regardless of treatment duration. (Level of Evidence: A) Class IIb6. Patients with a first episode of unprovoked PE and low risk of bleeding, and in whom stable anticoagulation can be achieved, may be considered for long-term oral anticoagulation. (Level of Evidence: B) Class IIa7. For patients with PE and cancer, LMWH should be considered for the first 3–6 months (Level of Evidence: B) after this period, anticoagulant therapy with VKA or LMWH should be continued indefinitely or until the cancer is considered cured. (Class I,Level of Evidence: C) |
