Novel composite scoring system to predict unknown atrial fibrillation in acute ischemic stroke patients

Both CHADS2 and CHA2DS2-VASc scores are useful but not optimal for predicting newly detected AF in patients with acute ischemic stroke. A newly identified embolic features combining with the CHADS2 or CHA2DS2-VASc score for predicting AF in patients with stroke is superior to the CHADS2 or CHA2DS2-VASc score alone.
