Between 1 January 2021 and 1 July 2021, 120 blood samples from acute myocardial infarction (AMI) patients—60 as controls and 60 patients—of both sexes who were accepted to the cardiac surgery unit at AL- Salam teaching hospital, the intensive cardiac care unit, and outpatient clinics in Mosul City/Iraq, were taken. In the presented research, the ejection fraction regarding patients with AMI was evaluated by echocardiography, and the blood-liver enzyme levels (ALP and AST \ ALT ratio) were examined in those patients. The findings indicate that patients with AMI in the age range of 35 to 45 years have a (52.41) % ejection fraction (EF) rate, which is closer to (51.344%) than it is in samples from healthy controls. In addition to that, findings indicate that patients in an age range of 46 to 56 years have heart failure with a mid-range EF (HFmrEF), with a (48.13%) percentage, whereas this heart failure type in healthy controls has been preserved ejection fraction (HFpEF) with (53.368 %). In the case of the comparison of the AST/ALT ratio and EF across all of the age groups that have been tested, the results suggest a significant level (P ≤ 0.050) relation between the ALP enzyme and EF for the patients within the (35-45 years) age group additionally, as there has been a positive and weak linear connection (r = 0.10650) and a nominal p-value (p = 0.47240) at a threshold of probability ≤ P 0.050, the link and correlation between the AST/ALT ratio and cardiac EF have been investigated.
