Updates to Article Attributes
Body
was changed:
A submassive pulmonary embolism refers to an acute PEpulmonary embolism with evidence of myocardial necrosis or right ventricular dysfunction in the absence of systemic hypotension. An elevation in troponin I or T provides evidence of myocardial necrosis. Right ventricular dysfunction is defined by the presence of any of the following:
- echocardiographic evidence of right ventricular dilation or systolic dysfunction
- an RV/LV diameter ratio >0.9 on CT 4
- biomarker elevations
- brain natiuretic peptide (BNP) > 90 pg/mL or pro-BNP >500 pg/mL
- characteristic electrocardiographic abnormalities
- right bundle branch block
- anteroseptal ST-T wave abnormalities
