Iron supplementation for chronic heart failure.
If you have been told you have chronic heart failure (CHF) it means that your heart is not working well enough to pump the blood to your organs and tissues around your body.
Your heart may have been damaged or weakened by several conditions such as coronary artery disease, high blood pressure, heart valve defects or other factors such as alcohol misuse or viral infection.1
About 50 % of heart failure patients have some form of iron deficiency (ID), with or without anaemia. 2,3 If you are suffering from CHF, there are a few reasons why you may also be suffering from ID: 4
- You may be absorbing less iron from your food into your bloodstream because of changes to the gut wall
- You may not have enough iron in your diet
- Drug interactions may reduce the amount of iron you absorb
- Medications may also cause internal bleeding which means that more iron is lost from your body than normal
