BackgroundAcute coronary syndrome (ACS) is responsible for one-third of total deaths in people older than 35 years old. Number of prognostic models aims to estimate the future risk of mortality, or the combined risk of all-cause mortality or MI has been developed, such as GRACE score.ObjectiveThe aim of our study is to assess the utility of GA and CHA2DS2-VASc score in predicting outcomes in patients admitted with acute coronary syndromes.Patients and methodsThis study was conducted on 90 patients diagnosed with acute coronary syndrome who were admitted receiving PCI, CHA2DS2-VASc score was calculated on admission, and a serum sample for GA was withdrawn within 24 h from admission.ResultsCombined GA and CHA2DS2-VASc score could significantly predict MACCE with sensitivity 100%, specificity 79%, and diagnostic accuracy 80.9% and significantly predict hospital mortality with sensitivity 100%, specificity 75.3%, and diagnostic accuracy 76.7%; on the other hand, GRACE score can predict MACCE using cutoff point 112.5 with sensitivity 75% and specificity 66%.ConclusionIt was concluded that GA and CHADSVASC score can significantly predict major adverse cardiovascular events, in-hospital mortality, and poor clinical outcomes.
