Yes, research suggets that patients already having chronic heart diseases are susceptible to sudden pain in the chest or angina due to low levels of iron in the body. Hence, it is advisable to maintain healthy iron levels in the body to prevent angina.

Two years ago I had a crawling sensation in my throat and I thought it was a worm. I also felt it in my stomach. I consulted an MD doctor and he said it was only gas in my stomach. He took my blood samples and the report showed very low haemoglobin even though I had a balanced diet. He prescribed me some vitamins. After a few weeks I started feeling the same again. Sometimes it is normal but while sleeping I start to feel the same crawling sensation in my throat and stomach.
