A high CHA 2 DS 2 VASc Score corresponds to a greater risk of stroke, while a low CHA 2 DS 2-VASc score corresponds to a lower risk of stroke. Der CHA 2 DS 2-VASc-Score ist eine Weiterentwicklung des CHADS 2-Scores, die vor allem in Europa, seit 2014 aber auch in den USA verwendet wird.Er dient wie der CHADS 2-Scores der Risikoabschätzung eines Schlaganfalls bei Vorhofflimmern.. The CHA2DS2-VASc score is a refinement of CHADS2 score and extends the latter by including additional common stroke risk factors. 2 Hintergrund. 1 Definition. How does this CHA2DS2 VASc score for atrial fibrillation stroke risk calculator work? The CHA 2 DS 2-VASc score (Birmingham 2009) was developed after identifying additional stroke risk factors in patients with atrial fibrillation (AF).. Go to the MDCalc CHA 2 DS 2-VASc Score for Atrial Fibrillation Stroke Risk.. Notes. CHADs-VASC-Score und CHA 2 DS 2-VASC-Score sind Synonyme für das gleiche Punktesystem, das zur Abschätzung des Schlaganfallrisikos angewendet wird. Die Bezeichnung CHA 2 DS 2 -VASC ist etwas genauer: Die Buchstaben stehen für die berücksichtigten Risikofaktoren, die Zahlen geben die Gewichtung an. The maximum CHADS 2 score is 6, while the maximum CHA 2 DS 2-VASc score is 9. Die Sinnhaftigkeit dieses Scores wurde anfangs kontrovers diskutiert. Consider using the CHA 2 DS 2-VASc score to further risk stratify patients who are identified as low risk by their CHADS 2 score. One recommendation suggests a 0 score is low risk and may not require anticoagulation, however there is literature that suggests that not all patients with a CHADS 2 score of 0 are at low risk for ischemic stroke.. This is a health tool that is used to estimate the thromboembolic status of patients suffering from non valvular atrial fibrillation who are not under any anticoagulation treatment at the moment of the assessment.It is based on the CHA2DS2-VASc score which is an improved version of the previous CHADS2 score.
