Abstract
The intriguing role of the oxidation system in cardiovascular disease lies in its contribution to chronic and acute increases in intracellular reactive oxygen species (ROS), driving the progression of cardiovascular diseases (CVDs). ROS, produced as by-products of oxidative physiological and metabolic events, act as mediators in various signaling pathways contributing to cardiovascular pathology. The delicate equilibrium between the production of free radicals and antioxidant defense shifts in favor of the former, resulting in redox imbalance and extensive cellular damage. Among CVDs, coronary artery disease (CAD) remains as the leading cause of death globally. Understanding the significance of oxidative damage in the dysfunction of endothelial cells, atherosclerosis, and other pathogenic events and pathways is crucial for preventing and managing CVD. Consequently, it is imperative to comprehend the mechanism/s underlying the pathogenic alterations of CVD due to oxidative damage to develop effective prevention strategies. Many studies have reported bioactive phytochemical/s as potential therapies against CVDs, modulating ROS generation, controlling the CVD-related inflammatory mediators and protecting the vascular system. Therefore, this review provides an update for understanding how the phytoconstituents exhibit preventive roles in oxidative stress-related CVD, thus improving the quality of life of people. This study conducted a thorough literature search on CVD, oxidative imbalance, and phytoconstituents. The search was performed using multiple search engines and the main keywords, and only English publications until June 2023 were included. However, there is a need for more research and clinical trials to fully elucidate the efficacy and safety of these phytochemicals for managing the disease.
