The most frequent cause of hospitalization in adults over 65 in Western nations is acute decompensation of heart failure (ADHF). Due to the high death rate, it places a heavy load on healthcare systems as well as people. The present study’s objective was to ascertain the connection between polymorphisms in the Glutathione S-transferase Mu 1 (GSTM1) gene and heart-failure-reduced ejection fraction (HFrEF) patients. Sixty patients with a mean age of 25–94 were taken from both genders after the clinical diagnosis by a specialist to cases who were referred to the Ibn Al-Baitar Specialized Center for Cardiac Surgery and Ramadi Teaching Hospital, and thirty apparently healthy people were taken as a control. Blood and serum containing EDTA were drawn from sick and healthy people to extract DNA for multiplex PCR detection of the GSTM1 polymorphism. The GSTM1 genotype was found in 23 (38.33%) and the null gene in 37 (61.66%) of the 60 ADHF patients. Of 30 healthy people, 8 (26.66%) had the GSTM1 gene and 22 (73.33%) had the null gene. According to the present study, the etiology of acute decompensated heart failure (ADHF) and the antioxidant null gene (GSTM1) are related. The present study has been achieved to determine the relationship between the presence of the antioxidant gene (GSTM1) and the incidence of ADHF with reduced ejection fraction for research and therapeutic purposes, which opens new spaces in the treatment of the mentioned condition.
