Why the study?
Cardiomyocyte death is a key pathophysiological basis for ischemic cardiomyopathy, and ferroptosis is thought to play an important role, prompting exploration of ferroptosis-related genes and immune infiltration.
Population
Patients with ICM and healthy controls
Comparison
Patients with ICM vs healthy controls
Design
Bioinformatics dataset analysis and qRT-PCR validation study
Key result
Patients with ischemic cardiomyopathy exhibited significantly higher expression of ferroptosis-related genes IL6 and JUN, and lower expression of STAT3 and ATM, compared to healthy controls.

Hypothesis-generating for ferroptosis in ischemic cardiomyopathy; prospective validation required before clinical relevance.
Case-Control (n=40)
No
Ferroptosis-related genes and immune checkpoint factors are significantly altered in ischemic cardiomyopathy, suggesting a role for ferroptosis and immune infiltration in its pathogenesis.
Huang et al. (2023) conducted a case-control in Ischemic cardiomyopathy (n=40). Ischemic cardiomyopathy vs. Healthy controls was evaluated on Expression levels of ferroptosis-related genes (IL6, JUN, STAT3, ATM). Patients with ischemic cardiomyopathy exhibited significantly higher expression of ferroptosis-related genes IL6 and JUN, and lower expression of STAT3 and ATM, compared to healthy controls.
