C inhiba oxidarea lipoproteinele cu densitate joasa - LDL si ateroscleroza
- Liproproteina(a) are efect de lipire (Adeziune) de peretii vasculari,
a moleculei LDL (Low Density Lipoprotein) a depunerilor de molecule de Calciu
si molecule de Zahar (glucoza).
| Placa aterosclerotica cu tromb |
 |
Cardiopatia ischemica poate fi produsa de cauze organice cum ar
fi:
Leziuni in peretii vasculari datorita oxidatiei din insuficienta a antioxidantilor
pentru reducerea radicalilor liberi, Coenzima Q10 este un antioxidant puternic.
- Din lipsa cronica de Vitamina C peretii vasculari primesc leziuni
iar efectele de reparatie a organizmului compenseaza necontrolat cresterea
cu celule musculare
