Summary
Genetic variations influencing oxidative stress are key to understanding heart failure susceptibility and progression. This review examines polymorphisms in genes related to oxidative stress and their impact on heart failure development.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Molecular Biology
Background:
- Heart failure stems from cardiovascular diseases or idiopathic dilated cardiomyopathy.
- Understanding cellular events in heart failure pathogenesis is crucial for diagnosis, prevention, and therapy.
- Genetic background research in cardiomyopathies lags behind monogenic diseases.
Purpose of the Study:
- To review current data on the role of gene polymorphisms related to oxidative stress.
- To explore the influence of these polymorphisms on heart failure susceptibility and progression.
Main Methods:
- Review of existing clinical association studies.
- Analysis of genetic polymorphisms in genes involved in oxidative stress pathways.
Main Results:
- Reactive oxygen species are significantly implicated in heart failure pathogenesis.
- Genetic polymorphisms in oxidative stress-related genes may influence heart failure risk and progression.
Conclusions:
- Oxidative stress-related gene polymorphisms are important factors in heart failure.
- Further research into these genetic variations can aid in identifying susceptible individuals and guiding therapeutic strategies.
