Background: Cardiomyopathy (CM) is a cardiac muscle disorder that can lead to heart failure (HF). It has several phenotypes, including dilated, hypertrophic, and restricted. Pro-inflammatory cytokines play a crucial part in the development and advancement of CM. Objective: This study aimed to measure the concentration of certain cytokines [Interleukin- 1β (IL-1β), Interleukin-6 (IL-6), and Tumor Necrosis Factor (TNF-α)] in the serum of Iraqi patients with CM. Materials and Methods: Sixty CM patients and 30 healthy individuals with age ranged from 40 to 70 years old were enrolled in this study through their presence at Iraqi Center for Heart Diseases, Ghazy Al-Hariri Hospital for Surgical Specialties in the Medical City in Baghdad. The study was conducted from November 2021 to April 2022. Blood samples were collected to evaluate the level of Interleukin IL-1β, IL-6, and TNF- α using ELISA technique. Results: The findings revealed a highly significant (P≤0.01) increase in the level of IL-1β IL-6 and TNF- α (15.71 ±0.33 pg/ml, 65.84 ±0.73pg/ml, and 17.81 ±0.58 pg/mL) respectively in comparison with control (4.59 ±0.17 pg/ml, 7.60 ±0.18pg/ml, and 6.26 ±0.34 pg/mL) respectively. Conclusion: It can be concluded from the current results that the pro-inflammatory cytokines play a major role in the development and severity of cardiomyopathy in Iraqi patients.
