About

Studies have shown that aging can promote a variety of pathological processes, such as myocardial remodeling and cardiac dysfunction caused by ischemia-reperfusion injury and pressure load. Previous studies found that the level of circulating beta-hydroxybutyric acid decreased significantly with age. It has been reported that the ketogenic diet reduces the occurrence of tumors and neurodegenerative diseases in mice, improves motor coordination and endurance, and ultimately extends life span. Current research results have confirmed that ketone bodies have multiple mechanisms to exert beneficial effects on cardiovascular diseases. However, the effect of age-related cardiovascular disease has not been reported.

In order to further clarify the role of beta-hydroxybutyric acid in age-related cardiovascular diseases, find new intervention targets for elderly cardiovascular diseases, and develop new effective prevention and treatment measures for elderly cardiovascular diseases. We will further investigate this hypothesis by establishing a clinical cohort of the elderly population.

Full description

It is predicted that by 2050, the total number of people over 65 years old in China will reach 400 million (accounting for 26.9% of the total population), and the number of people over 80 years old will reach 150 million. Population aging is the main driving force of cardiovascular diseases, and cardiovascular diseases in the elderly will become a major clinical problem threatening the health of our people and a social problem involving people's livelihood. Therefore, it is an important research direction in the cardiovascular field to deeply explore the pathogenesis of elderly cardiovascular diseases and find effective prevention and control targets.
