介绍

Heart failure is one of the leading causes of morbidity and mortality worldwide. 然而, it does not develop suddenly—it is the result of progressive structural and functional changes in the heart over time.

Early stages of cardiac dysfunction, 通常被称为 pre-heart failure or Stage A/B heart failure, involve subtle changes such as:

• Mild ventricular dysfunction
• Early fibrosis
• 微血管损伤
• Reduced cardiac reserve

现阶段, the heart still has the potential to recover and regenerate, making early intervention critical.

Traditional therapies focus on risk factor management but do not actively repair damaged myocardium.

干细胞治疗 represents a paradigm shift by offering the possibility to intervene early, regenerate cardiac tissue, and prevent progression to overt heart failure.

What Is Early Heart Failure and Why Is It Important?

问题: What is early-stage heart failure?
回答: Early heart failure refers to the initial phases of cardiac dysfunction where structural changes are present but symptoms may be minimal or absent.

问题: Why is early intervention critical?
回答: 因为:

• Damage is still reversible
• Fibrosis is limited
• Cardiomyocytes are still viable
• Regenerative therapies are more effective

Early treatment can delay or even prevent progression to advanced heart failure.

Which Stem Cells Are Used for Early Heart Failure Prevention?

间充质干细胞 (间充质干细胞)

问题: Why are MSCs ideal for early intervention?
回答: 间充质干细胞减少炎症, 限制纤维化, 并促进血管生成, 帮助 preserve cardiac function before irreversible damage occurs.

诱导多能干细胞 (诱导多能干细胞)

问题: Can iPSCs prevent heart failure progression?
回答: 是的. iPSCs can generate new cardiomyocytes and vascular cells, supporting early regeneration and structural repair.

内皮祖细胞 (EPC)

问题: What role do EPCs play in prevention?
回答: EPCs improve endothelial function and microcirculation, 寻址 one of the earliest abnormalities in heart failure development.
