介绍

Obesity-related cardiomyopathy is a form of heart disease caused by chronic metabolic stress, excess adiposity, 和炎症, even in the absence of traditional risk factors like hypertension or coronary artery disease.

Patients may develop:

• 左心室肥厚
• Diastolic dysfunction
• 心肌纤维化
• 微血管损伤

Traditional therapies—weight loss, 生活方式的改变, and pharmacological treatments—often fail to reverse structural heart damage.

干细胞治疗 offers a novel regenerative approach to:

• Repair myocardial tissue
• 减少纤维化
• Restore microvascular circulation
• Improve overall cardiac function

How Obesity Impacts the Heart

问题: How does obesity cause cardiomyopathy?
回答: Obesity affects the heart through:

• 慢性炎症
• 氧化应激增加
• Lipotoxicity in cardiomyocytes
• 微血管稀疏
• 内皮功能障碍

这些变化导致 structural remodeling, impaired contractility, 以及最终的心力衰竭.

问题: Can obesity-related cardiomyopathy be asymptomatic?
回答: 是的. Many patients develop diastolic dysfunction without early symptoms, delaying diagnosis and treatment.
