Oxidative Stress in Cardiovascular Diseases

Cardiovascular diseases encompass a range of pathologies that affect the heart or blood vessels. Oxidative stress is an important factor that contributes to the development of these pathologies. Adverse effects due to oxidative stress manifest when there is an imbalance between the production and elimination of reactive oxygen species (ROS), or when physiological mechanisms of repair for oxidative injury are overburdened. This chapter focuses on ROS accumulation and antioxidant system deficiencies in the context of their influence on cardiovascular disease. We also discuss the importance of high throughput approaches, such as proteomics, with regard to their role in advancing the field of precision medicine for cardiovascular diseases, while keeping in mind the ultimate goal of improving patient care and quality of life.
