介绍

Cardiovascular aging is one of the primary drivers of morbidity and mortality worldwide. 随着心脏年龄的增长, it undergoes structural and functional changes, including myocardial stiffness, reduced regenerative capacity, 内皮功能障碍, and increased fibrosis.

These changes lead to increased risk of heart failure, 心律失常, 和血管疾病, even in otherwise healthy individuals.

Traditional approaches—such as lifestyle interventions and medications—can slow aging but cannot reverse the underlying biological decline of cardiac tissue.

干细胞治疗 is emerging as a powerful tool in regenerative cardiology and longevity medicine, offering the possibility to rejuvenate the aging heart, 恢复功能, and extend cardiovascular healthspan.

What Happens to the Heart During Aging?

问题: Why does the heart age?
回答: Cardiac aging results from multiple processes:

• Cellular senescence
• 线粒体功能障碍
• 氧化应激
• 慢性低度炎症
• Reduced stem cell activity

These changes lead to decreased cardiac regeneration and progressive structural decline.

问题: What are the main effects of cardiac aging?
回答:

• 心肌僵硬度增加
• Reduced diastolic function
• 内皮功能障碍
• Increased fibrosis
• 运动能力降低
