مقدمة

Arrhythmogenic cardiomyopathy (ACM), including arrhythmogenic right ventricular cardiomyopathy (ARVC), is a genetic heart disorder characterized by fibrofatty replacement of myocardium, ventricular arrhythmias, and progressive cardiac dysfunction. It is a major cause of sudden cardiac death in young individuals and athletes.

Current treatment strategies—such as antiarrhythmic drugs, implantable cardioverter-defibrillators (ICDs), and lifestyle modification—primarily focus on preventing arrhythmias rather than repairing myocardial damage.

العلاج بالخلايا الجذعية represents a novel regenerative approach aimed at restoring myocardial structure, الحد من التليف, and stabilizing electrical activity in patients with ACM.

This article explores cutting-edge stem cell therapies for arrhythmogenic cardiomyopathy, including mechanisms of action, clinical evidence, and answers to key questions frequently asked by clinicians and patients.

Which Stem Cells Are Used in Arrhythmogenic Cardiomyopathy?

الخلايا الجذعية الوسيطة (اللجان الدائمة)

سؤال: Why are MSCs promising for ACM treatment?
إجابة: MSCs possess strong anti-inflammatory and anti-fibrotic properties, helping to reduce fibrofatty infiltration of the myocardium. They also secrete factors that stabilize electrical conduction and reduce arrhythmogenic risk.

الخلايا الجذعية المحفزة (iPSCs)

سؤال: Can iPSCs correct genetic defects in ACM?
إجابة: iPSCs can be derived from patients and genetically corrected in vitro. These corrected cells can then differentiate into healthy cardiomyocytes, offering a potential personalized therapy for genetic cardiomyopathies.
