Prognostic impact of renal dysfunction in patients with acute coronary syndrome-role beyond the CHA2DS2-VASc score: Data from Taiwan acute coronary syndrome full spectrum registry

Aim CHA2DS2‐VASc score has been proven to have great prognostic value in patients with acute coronary syndrome (ACS). We aimed to determine whether the addition of renal dysfunction in the CHA2DS2‐VASc score would improve the prognostic impact of the scoring system to predict prognosis among ACS patients. Methods A total of 3031 ACS patients were prospectively enrolled at 39 hospitals and followed for 1 year. The patients were divided into three groups based on estimated glomerular filtration rate (eGFR) (group 1, eGFR>90; group 2, eGFR between 60 and 90; and group 3, eGFR
