Objectives: To compare the effectiveness of pretreatment with beta blocker vs without beta blocker in patients presenting with acute coronary syndrome (ACS) in terms of early mortality. Methodology: A total of 348 consecutive patients presenting with ACS were included in the study. All patients with diabetes mellitus were excluded. All patients were monitored in the CCU and echocardiograms were performed. All were examined and evaluated for third heart sound and crepitations. Group A (Pretreatment group) was those who are taking beta blocker already for any cause before presentation and Group B (control group) was those who are not taking beta blocker before. Results: In Group A, mean age was 52±1.27 years where as in Group B it was 54±1.32. In Group A, 62% patients were male and 38% patients were female where as in Group B 60% patients were male and 40% patients were female
