Hello and thank you for using HCM. I carefully read you question and i got through your query. Don t worry, you should not avoid salt completely. It is not necessary such an extreme modality. Let me explain you something. The fact that you have done an angioplasty means that you have ischemic heart disease. It is mandatory for you now to maintain your heart as healthy as possible, lowering her excessive work. This means that the heart must have an adapt frequency and work within normal blood pressure. Restricting your salt intake helps you to maintain low blood pressure values, helping your heart to work within normal conditions.This is why we advise you to avoid salt, but it is not necessary to completely leave it, but just to reduce it as much as posible in food intakes You should all sow be very careful with your cholesterol, with a healthy rich fiber and low cholesterol diet. Hope I was helpful. BEST REGARDS
