The aging of cells within the body is one of the major reasons for the development of diseases like atherosclerosis and heart failure by weakening the functionality of vascular smooth muscle cells as they age, leading to issues such as reduced nitric oxide generation and impaired contractility that contribute to problems like endothelial dysfunction and increased vascular stiffness. In addition, senescent cells release inflammatory substances as part of the senescence-related secretory phenotype (SASP), which worsens inflammation in the area and boosts plaque instability while speeding up atherosclerosis development. The continuous buildup of these cells worsens the process of aging by causing issues like dysfunction and oxidative stress as well as changes in epigenetics—all of which upset the balance in blood vessels. This chapter focuses on the dire need to lower the impact of senescence on heart health. Exploring pathways like NF-κB, p38MAP kinase, and mTOR that regulate SASPs and drive processes reveals promising possibilities in targeting these pathways with treatments such as senolytics and senomorphics, showing the potential to lower burdens of senescent cells to reduce inflammation and enhance function. This study focuses on opportunities for creating potential strategies to slow down or reverse aging in blood vessels, thereby decreasing cardiovascular diseases in older individuals. Addressed cellular senescence and related inflammatory reactions could pave the way for future therapies that greatly improve heart health and longevity.
