Hi eesha,
Heart failure in thals occur due to iron overload in heart,as Sajid explained that once the liver maxes out it's iron storing capacity,the iron starts to get stored in other organs including heart, so the only precaution we can take against heart failure is chelation ,or may i say strict schedule of chelation,according to what your ferritin levels are,that way iron would not be stored in heart,And i believe supplementation of megnesium and calcium is also necessary for keeping your heart well functioning,do share with us what exactly your ferritin level is,which chelators are you using?
ZAINI.
