CHADS-VASc Score can predict no-reflow in the settings of acute ST-elevated myocardial infarction.

BACKGROUND

No-reflow (NR) is one of the serious complications of primary percutaneous coronary intervention (PCI) and it is related to higher short- and long-term mortality. In this study, we aim to determine NR possibility with a scoring system.

METHODS

This retrospective, single-center study included consecutive patients diagnosed with acute ST- segment elevation myocardial infarction (STEMI) and treated by PCI, between May 2019 and May 2024.

RESULTS

A total 1050 patients were included: patients were divided to two groups according to the final coronary flow: NR group ( = 139) and control group ( = 930). CHADS-VASc score was calculated for all the patients and multivariable regression and receiver operating characteristic curve analyses were conducted to determine the independent predictors of NR and cut-off value of CHAD-VASc score. CHAD-VASc cut-off values of 2 have a sensitivity of 84.2% and a specificity of 30% (The area under the curve (AUC) was calculated to be 0.615).

CONCLUSION

A CHADS-VASc score ≥ 2 may serve as a valuable predictive tool for identifying the occurrence of NR in patients with STEMI. The sensitivity demonstrated in our study offers clinicians a practical approach for risk stratification and management of patients at risk of developing NR.
