Congratulations Dr. Adesina! and thanks for the Morning Report!
Management of Submassive (Intermediate Risk) PE
Massive PE (high risk): acute PE causing hemodynamic instability and hypotension, pulselessness, or profound bradycardia
Submassive PE (intermediate risk): hemodynamically stable PE w/ right ventricular dysfunction (RVD) or myocardial necrosis.
Low risk PE: lacks RVD or hypotension.
| RV DysfunctionPresence of at least 1 of the following: |
| — RV dilation (apical 4-chamber RV diameter divided by LV diameter >0.9) or RV systolic dysfunction on echocardiography — RV dilation (4-chamber RV diameter divided by LV diameter >0.9) on CT
— Elevation of BNP (>90 pg/mL) — Electrocardiographic changes (new complete or incomplete right bundle-branch block, anteroseptal ST elevation or depression, or anteroseptal T-wave inversion) |
PEITHO
- Effectiveness of full dose tenecteplase with heparin(TG) compared to heparin(CG) in patients with intermediate-risk pulmonary embolus.
- TG had less hemodynamic compromise, but higher risk of hemorrhage and stroke.
MOPETT trial
- Role of half-dose alteplase with heparin in reduction of pulmonary artery pressure in moderate risk PE.
- Thrombolytic (ateplase +anticoagulation) group had less pulmonary hypertension, recurrent PE and death when compared to control (anticoagulation alone).
- Bleeding did not occur in the treatment or control group.
- The results of the study suggest that half-doses alteplase is safe and effective in moderate PE with reduction in pulmonary hypertension.
Metanalysis (Chaterjee et al.)
- Compared thrombolysis to anticoagulant therapy in patients with intermediate risk PE.
- Outcomes: all-cause mortality and bleeding risk.
- Thrombolytics were associated with overall lower all-cause mortality, lower rate of recurrent PE, and greater risk of major bleeding.
- However, major bleeding was not seen in patients 65 and younger
