The difference between the tools in the predictive ability for MACE was highly significant (p =0.0001). The Thrombolysis in Myocardial Infarction (TIMI) Score is used to determine the likelihood of ischemic events or mortality in patients with unstable angina or nonST-segment elevation. Results: TIMI risk score has the highest predictive performance of all risk stratification tools, as AUG is greatest (0.93) also, it has the highest sensitivity for MACE (96.5%) Goldman risk score has the highest specificity for MACE (60%). Potentially eligible patients were identified in the ED triage area and assessed for study with follow-up throughout their hospital stays for Major Adverse Cardiac Events (MACE). TIMI risk score is a simple risk stratification tool established to predict secondary events in patients with ACS and currently is applied for patients having. Methods: The study was carried out among 60 patients presenting with non-traumatic chest pain for which no definitive non-ischemic cause was found. Aim: of the study was improving the management process in patients with Acute Coronary Syndrome and predicts their outcome at the emergency department. Background: The Thrombolysis in Myocardial Infarction (TIMI) score is considered a method for early risk stratification in patients with unstable angina/non-ST. Moreover, the problem of (no monitored bed available) with increasing the length of stay at the emergency department. Unnecessary admissions for chest pain in the U.S. Of those admitted for chest pain, more than 60 percent do not have acute coronary syndromes. Of the patients presenting to the emergency department for chest pain, 55 to 85 percent do not have a cardiac cause for their symptoms. It is superior to ECG changes and troponin alone, although this simpler method also achieves good risk stratification. Introduction: Emergency department clinicians have a difficult task identifying which patients to admit and which patients to discharge home. Discussion: The TIMI risk score is a valid tool for risk stratification in unselected cases with possible acute coronary syndrome.
