Li X, Zeng Z, Yang X, et al. - CHADS2 and CHA2DS2-VASc scores were evaluated for their value in predicting coronary artery lesions and in-hospital prognosis of patients with acute ST-segment elevation myocardial infarction (STEMI).

• A retrospective review of a total of 524 patients who were diagnosed with STEMI.

• Mainly single and double coronary lesions were observed in STEMI patients.

• No prediction of the number of coronary lesions could be made using the CHADS2 and CHA2DS2-VASc scores.

• However, for the left main coronary artery lesion, significantly increased CHADS2 score was recorded when the number increased.

• In STEMI patients, the incidence of target lesions was mainly left anterior descending coronary artery (LAD) and right coronary artery (RCA).

• There was no predictive value of the two scores for target lesions.

• For the severity of coronary lesions, positive correlation appeared between CHADS2 score with Gensini score, but there was no exact correlation between CHA2DS2-VASc score and Gensini score.

• The stratifications of CHADS2 score and CHA2DS2-VASc score revealed longer hospitalization time and more AEs during hospitalization in the high score group than the low score group and the middle group.

• Overall, there is a certain value of CHADS2 score in predicting the severity of coronary lesion and the presence of left main coronary artery.
