- In the literature, echocardiographic assessment of the prognosis of acute pulmonary embolism is based on analysis of right ventricle free-wall motion or on a composite index combining right ventricular dilatation, paradoxical septal wall motion, and pulmonary hypertension. The aim of this study was to determine the prognostic value of a single quantitative echocardiographic criterion, the right/left ventricular end-diastolic diameter (RV/LV) ratio.
- More aggressive management may be warranted for patients with acute pulmonary embolism (PE) and the greatest pulmonary vascular obstruction. We hypothesized that a scoring system based on the ECG might identify such patients.
- To compare the diagnostic performance of volumetric capnography (VCap), which is the plot of the expired CO2 partial pressure against the expired volume during a single breath, with the Paco2 to end-tidal CO2 (EtCO2) gradient, in the case of suspected pulmonary embolism (PE).
- Massive pulmonary embolism (PE) that causes severe pulmonary hypertension can produce specific ECG abnormalities. We hypothesized that an ECG scoring system would vary in proportion to the severity of pulmonary hypertension and would help to distinguish patients with massive PE from patients with smaller PE and those without PE.
