Electrocardiographic findings associated with early clinical deterioration in acute pulmonary embolism.
Investigators sought to determine associations of early ECG patterns with clinical deterioration (CD) within 5 days and with RV abnormality (abnlRV) by echocardiography in PE. They found that supraventricular tachycardia was an independent predictor of CD, while T-wave inversion, incomplete right bundle branch block, ST-segment elevation aVR, sinus tachycardia, and S1-Q3-T3 were independent predictors of abnlRV. They suggested that finding one or more of these ECG patterns may increase considerations for performance of echocardiography to look for RV abnormalities and, if present, inform concerns for early clinical deterioration.

Can right ventricular assessments improve triaging of low risk pulmonary embolism?
Researchers sought to determine if right ventricle (RV) assessment variables add prognostic accuracy for 5-day clinical deterioration in patients classified low risk by the Simplified Pulmonary Embolism Severity Index and to determine the prognostic importance of RV assessments compared to other variables and to each other. They found that a pulmonary embolism triaging strategy with RV imaging assessments had superior prognostic performance at classifying low risk for 5-day clinical deterioration versus one without.

Automated pulmonary embolism risk assessment using the Wells criteria: validation study.
The authors sought to create an automated process to calculate the Wells score for pulmonary embolism for emergency department patients, which might reduce unnecessary computed tomography pulmonary angiography (CTPA) testing. They designed the process using electronic health records data elements, including free-text fields, and calculated Wells scores for a sample of adult emergency department visits that resulted in a CTPA study for pulmonary embolism at two tertiary care hospitals in New York. After validation, the authors concluded that the development of the automated process to classify risk for pulmonary embolism in emergency department visits was successful.
