Right ventricular (RV) function is predictive of outcome in patients with acute pulmonary embolism (PE). We assessed the possible incremental value of ventricular function with ECG-synchronized cardiac CT scanning over pulmonary CT scan angiography (CTA) for predicting short-term outcome in patients with suspected acute PE. ⋯ RVEF was the best predictor for clinical outcome in patients with acute PE. However, incremental value of RVEF over axial RV/LV ratio was not found.

All stroke risk stratification schemes categorize a history of stroke as a "truly high" risk factor. Therefore, stratifying stroke risk in atrial fibrillation (AF) should perhaps concentrate on primary prevention. However, the risk factors for stroke also lead to an increase in the risk of bleeding. Our objective was to evaluate the agreement among the currently used stroke risk stratification schemes in "real-world" patients with AF in the primary prevention setting, their correlation with adverse events recorded during warfarin treatment, and the relationship between stroke and bleeding risk. ⋯ Stroke risk stratification models differed widely when categorizing subjects into the moderate- and high-stroke-risk categories. Bleeding and stroke risk were closely correlated and both were low among low-risk patients and were similarly high among moderate/high-risk groups.
