Background: A quick but thorough assessment of the patient’s history and findings on physical examination, electrocardiography, and cardiac biomarker tests permit accurate diagnosis and aid in early risk stratification. This work aimed to analyze the diagnostic and prognostic tools, the modalities of management, and the hospital outcome of patients with acute coronary syndrome (ACS) at Tanta University Hospital in one year.
 Methods: This ACS registry at Tanta university hospital is a prospective observational registry for 200 consecutive admitted patients with proven ACS from January 2019 to January 2020.
 Results: A higher percent of hypertension, family history of ischemic heart disease and SCD, previous history of chronic kidney disease (CKD), and lower percent of a previous history of IHD in STEMI compared to NSTEMI/UA. In-hospital death, in-hospital reinfarction, and reduced ejection fraction are higher in STEMI than in NSTEMI/UA patients. (P value = 0.015, 0.018 and 0.001 respectively) without significant differences regarding in-hospital congestive heart failure (CHF) and ischemic stroke. History of CKD, higher Killip class, and in-hospital stroke were independently affecting in-hospital mortality. Also, the history of higher Killip class was independently affecting in-hospital reinfarction and in-hospital CHF. Old age and occurrence of in-hospital reinfarction were independently affecting in-hospital stroke.
 Conclusion: Hypertension, diabetes, dyslipidemia, and smoking are the major risk factors for ACS so, controlling these risk factors will improve in-hospital outcomes. In STEMI, most patients underwent PPCI, which was reflected in the outcome. In NSTEMI/UA patients, both conservative and invasive management was done, taking into consideration the risk stratification of each patient, making management easier and with a good outcome.
