Myocardial necrosis caused by ischemia is called a myocardial infarction (MI). which interrupts coronary blood supply. When the oxygen supply to the heart is insufficient to meet metabolic demands, myocardial ischemia occurs. Atherosclerosis, which obstructs the coronary arteries, is the most common underlying cause of myocardial ischemia. The role of arginase-1 (ARG-1) and serum lipids in the pathogenesis of myocardial infarction is becoming clearer. This study aims to see if there is a link between ARG-1 activity and MI in the Iraqi population. Between the first of November 2021 and the first of February 2022, 90 people were separated into two groups: 45 patients with MI and 45 healthy controls. Human ARG-1 was measured in serum blood using the ELISA method. The serum lipid was measured using the spectrophotometry technique. The current investigation discovered a substantial (p=0.01) rise in ARG-1 concentration compared to control groups, as well as a significant difference in blood lipid content between patients and control groups (p
